XSS For Managers

What is Cross-Site Scripting (XSS)?

Cross-Site Scripting (XSS) is a type of vulnerability which is very widespread and allows an attacker to insert malicious code (JavaScript) into your web browser via the use of a vulnerable web application. The attacker can deliver their malicious code in a number of different ways.

They can trick you into clicking on a link (Reflected XSS), or wait for you to visit a page which already has the malicious code embedded into it (Stored or Persistent XSS).


That annoying pop-up box with the number 1 in it? That's just a way that some people visually prove that their JavaScript (XSS) has been run. But don't let that lousy pop-up box fool you, there is a lot more to XSS than that!

What can hackers do with XSS?

  • A hacker may be able to steal your 'cookies' and login to the application as if they were you!
  • They may be able to redirect you to a malicious web site without you knowing in an attempt to trick you into giving away sensitive information such as your bank details.
  • They could add fake login pages to the vulnerable application to trick you into giving them your username and password.
  • They could even use XSS to bypass other security measures which are built into the application and your web browser to protect you.
  • The possibilities are almost limitless. Take over your webcam? Yep! Listen in on your computer's microphone?

For advanced attacks see the The Browser Exploitation Framework (BeEF) tool.

Who's been hacked using XSS?

  • The Apache Foundation, the creators and maintainers of one of the most popular web server software on the Internet had their servers compromised by an initial XSS attack.
  • An XSS attack on the official forum of the popular Linux Operating System, Ubuntu, allowed the attackers to download the usernames, email addresses and passwords for 1.82 million of their users.
  • XSS attacks typically target the application's users and their local networks; however, as seen in the examples above, when those users are administrative users the application's web servers are also at risk.
  • XSS vulnerabilities are discovered within Facebook, Yahoo, Google, Twitter and other high profile websites on a daily basis by independent security researchers participating in bug bounties.
Here is a list of other hacks using XSS -https://www.google.com/fusiontables/DataSource?snapid=S1158702BBoV

What can I do to protect myself against XSS?

  • Make sure that your web browser is kept up to date and that it has all of its security features enabled, such as Cross-Site Scripting (XSS) filtering. If your particular browser does not have an XSS filter, like Firefox, then you can download an XSS filter add-on called NoScript.
  • Be careful about what links you click on. A link may look harmless enough, but may contain malicious XSS payloads.
  • Log out of web sites when you are finished with them, this makes it harder for hackers to steal your 'cookies'.

The technical bit! What can I do to protect my web application against XSS?

  • Cross-Site Scripting occurs when untrusted input is output to a page without first being sanitised and/or properly encoded. For example, if a user supplies their username to login and then you display that username without sanitising and/or encoding it, what happens if the username contains HTML characters?

    The web browser will not be able to tell the difference between the user's username and what is the page's valid HTML. Data (the username) is being mixed with code (the HTML)! This could allow a user to login with a username that contains malicious JavaScript and have it execute in the browser within the context of your web application.
  • Make sure that you sanitise the username before using it, for example, if users should only have alpha numeric characters in their usernames then enforce this with input sanitisation. Use a whitelist! Compare the username against known goods instead of known bads.
  • Use the right encoding! If the username is going to be used within HTML, then HTML encode all of the username's characters.

    This way the browser will know what is meant to be rendered as HTML and what is not. It's not all about HTML encoding though! You must encode for the right output 'context'. See the links below for further information.
  • Scan your applications for XSS issues. There are many automated web application security scanners which can detect XSS issues in web applications. You could try giving the Open Source OWASP ZAP a go.
  • Set your session cookies with the HttpOnly flag. This tells the browser that the cookie should not be accessed by JavaScript, helping protect your users from having their sessions stolen.
  • A HTTP header called Content Security Policy (CSP) can be set by the web server to tell the web browser what and where JavaScript is allowed to be executed from. It uses a whitelist!
  • Finally, why not install a Web Application Firewall (WAF) such as the Open Source mod_security! A WAF will give your application that extra layer of defence to defend against those attackers but should be used in a defense in depth scenario and not as the only solution as bypasses are found often.

Where can I find further information?

The two types of XSS mentioned on this page (Reflected and Stored) are not the only two! We have only touched upon the subject here. Want to find out more?

The Open Web Application Security Project (OWASP) is a great resource for all things related to the security of web applications. Check out their wiki article on XSS or their XSS Prevention Cheat Sheet. For information on other types of web application vulnerabilities take a look at the OWASP Top 10.

Don't Get Burned by Twitter Updated-Privacy Policy

Twitter Carries a Torch for Privacy


In mid-May, Twitter published an updated privacy policy, which every Twitter user should read - and other social media sites would be smart to emulate. The policy includes a clearer explanation of the situations in which Twitter will share user information with others.


Most notably, the policy provides better clarifications about how your personal information is used than most other social media sites. The updates include a new section on how Twitter tailors content. It makes clear that Twitter can use users' contact information to help third-party services, client applications and others find Twitter accounts.


While that particular practice is not new, it is much more clearly stated today. The policy also indicates how users can opt-out of several data-sharing practices, which is incredibly important to privacy-minded individuals.


You may find Twitter very helpful to use for sharing information, learning of breaking news and doing research. It's a good option; just make sure you set your privacy settings appropriately.

Enable Do Not Track Feature In Web Browsers

How to enable the “Do Not Track feature” in a web browser, you are using?


You may not be aware about the all the modern web browser you are using, is tracking your every single details which might not be put to a good use, good or bad, not sure, but how would it feel if someone follows your every single click, every web page you are surfing, every single details you are entering somewhere and what it could mean, even I’m not sure.


But there are some features and settings which might put a stop on all these activities, a simple setting, a user have to tweak in order to enable the Do Not Track Feature. Most of the modern web browser supports “Do Not Track” Feature, it’s just you’ve to enable for it to work.


Let’s start with Google Chrome.


Unfortunately, there’s no built-in setting which you can enable Do Not Track feature in Google Chrome, but there are so many Google Chrome Extensions which you can use to add “Do Not Track” feature to it. So, simply use this Google Chrome extension to avoid any kind of web tracking. Just make sure you are using the latest Google Chrome web browser, at-least 17 or later. Add it, enable it, and you are free from spying.


Enable Do Not Track Feature In Mozilla Firefox



We don’t need any Add-on to enable Do Not Track feature in Mozilla Firefox. Just follow this quick tweak in Mozilla Firefox privacy settings and you are done. That’s the beauty of it.
  • Click on Firefox button.
firefox options tab
  • Move over to Options.
options tracking mozilla firefox
  • Under the Privacy Tab, check that box beside that says “Tell websites I do not want to be tracked”. Ok, and there you are, a free bird.

Enable Do Not Track Feature In Internet Explorer

internet explorer
To add that feature in Internet Explorer, visit this Do Not Track Test Page, and under the heading that says “To express your preference not to be tracked in IE9”, click on that link. Make sure you are clicking that using Internet Explorer 9.

Official Australian e-health info page defaced

Australian website hacked!


An apparent trio of ‘hackers’ operating under the LatinHackTeam banner has claimed the Australian Government’s Department of Health and Ageing eHealth education site as its 13,789th ‘defacement‘ victim.


The group’s latest record on Zone-H, a site that archives website vandalisations, is the department’s eHealth education site, publicleanring.ehealth.gov.au.


The site is a learning portal aimed at preparing consumers and healthcare professionals for the July 2012 launch of eHealth records in Australia. “infEkt”, “Adminp4nic” and “eCore” apparently do their homework, claiming to have targeted the site because they were “Against government corruption !!” “We are LatinHackTeam. We are three. We dont (sic) make DDOS. We do research. Respect us! Land of liberty, home of the brave..”


Most of the trio’s recent targets appear to be the websites of government organisations, but they occasionally stray to target organisations like the Spanish Red Cross in Granada, regional websites of Amnesty International, and the Creative Commons (Peru). The most recent Australian target before the eHealth site was the Australian website of global automotive stereo company, Alpine. In that defacement, which occurred on May 6, the group said it was “Against Monopoly Companies”.


The snapshot of the Department of Health and Ageing’s eHealth education site defacement appears to have been taken on May 17.

How Developers Can Secure their Code?

5 Application Security Tips

Over the last 30 years, many organizations have done an amazing job of automating their business, resulting in productivity gains, efficiencies and innovations.

Unfortunately, the threat landscape has changed dramatically during this time. A lot of that application code, written without security in mind decades ago, is still the heart-and-soul of many enterprises. That code was designed for a world where computers could not be accessed remotely.

Since then, it has been wrapped, integrated, connected, ported, and most importantly, exposed. That application code is not strong enough to withstand today's threat.

OWASP has a number of free and open-source resources that developers can use right now to help secure their code.

5 Tips for Developers

Start with the OWASP Top Ten
- This awareness document will help you understand, identify, and fix the most critical application security risks quickly.

Get hands-on with WebGoat - WebGoat is a deliberately flawed application that is riddled with holes to give people the opportunity for hands-on learning. It is open-sourced to help developers and security testers get experience with real vulnerabilities.

Leverage the OWASP Cheat Sheets - This is a fantastic series from leading experts globally. Let me know what you think of the Cross-Site Scripting Prevention Cheat Sheet, one of OWASP's most popular pages.

Verify Your Applications - There is no substitute for getting real facts about the security of your application portfolio. OWASP Application Security Verification Standard helps developers get started scanning, testing and code reviewing with tools like OWASP Zap and CSRFTester.

Get Training - Perhaps the hardest thing about application security is that there are so many different ways that software can fail, particularly when it's targeted by a motivated attacker. The key is training to get started with securing applications quickly.

If instructor-led training isn't possible, eLearning solutions are available to allow developers to learn on-demand and get hands-on, practical experience with vulnerabilities, security controls and real code. Training is a remarkably effective way to reduce vulnerabilities.

Before you trust your business to application software, make certain that the people who are writing your code know how to defend your business and its assets. It's time to learn.

Massive SQL injection attack

Mass Injection hits over 694,000 URLs

Hundreds of thousands of URLs have been compromised—at the time of writing, 694,000—in an enormous and indiscriminate SQL injection attack. The attack has modified text stored in databases, with the result that pages served up by the attacked systems include within each page one or more references to a particular JavaScript file.

The attack appears to be indiscriminate in its targets, with compromised machines running ASP, ASP.NET, ColdFusion, JSP, and PHP, and no doubt others. SQL injection attacks, which exploit badly-written Web applications to directly perform actions against databases, are largely independent of the technology used to develop the applications themselves: the programming errors that allow SQL injection can be made in virtually any language.

The underlying cause is a programmer trusting input that comes from a Web page—either a value from a form, or a parameter in a URL—and passing this input directly into the database. If the input is malformed in a particular way, the result is that the database will run code of the attacker's choosing. In this case, the injected SQL is simply updating text fields within the database, to make them include an extra fragment of HTML. This HTML in turn loads a JavaScript from a remote server, typically "http://lizamoon.com/ur.php" or more recently, "http://alisa-carter.com/ur.php." Both domain names resolve to the same IP address, and presently that server is not functional, leaving browsers unable to load the malicious script when they visit infected pages. Previously, it contained a simple script to redirect users to a fake anti-virus site.

The massive scale of these attacks (and the rapidly growing number of affected URLs) was first noticed by Websense Security Labs. On Tuesday, around 28,000 URLs were compromised; now more than 20 times more URLs are infected, and the numbers are still growing. The injected code is also found on a number of product pages on Apple's iTunes Store. Apple fetches RSS feeds from podcasters that broadcast using iTunes, and in a number of cases these broadcasters have been compromised by the SQL injection attack. As a result, the malicious code has made its way into Apple's system.

However, due to the way Apple processes the RSS feeds, there appears to be no exploitation vector; the injected HTML is safely nullified. SQL injections following this pattern appear to have been happening off and on for six or more months now. The domain name hosting the JavaScript changes each time, but the file name—ur.php—and the style of injection remain consistent. The actions of the scripts have been similar too; pop-up windows and malware downloads. Previous efforts were on a much smaller scale, however: hundreds of compromised URLs instead of hundreds of thousands.

In these earlier cases, the attacks originated from IP addresses in eastern Europe and Russia. It's been a busy week for SQL injection; at the weekend, MySQL.com, the website of Oracle-owned open source database MySQL, was hacked, again using SQL injection. A little embarrassing for a database vendor to be unable to use its own database securely.

World Cup web traffic - the distribution of malicious malware is way up

Cisco Warns Of Rising World Cup Malware


As the world’s legitimate Web traffic increases, so do instances of spam e-mail, Internet-borne malware and general hacker activity. When special or unusual events happen — such as the current Gulf oil spill or the FIFA World Cup soccer tournament in South Africa — communications traffic of all kinds skyrockets. This takes into account text messaging, e-mail, Web searches, cell phone usage, television and Web streaming video, among others.


Cisco ScanSafe SAAS Web security service reported June 18 that after a week of World Cup activities, the global increase in Web traffic is up by an average of 27 percent during World Cup matches.


Japan noted the highest increase (53 percent), followed by the U.K. (37 percent), Germany (32 percent), Australia (20 percent) and Singapore (9 percent). In the United States, the increase worked out to about 8 percent — lower because soccer isn’t the overwhelming phenomenon there as it is worldwide.

Staying Anonymous in a Time of Surveillance

Read digital books? Then your e-book provider probably knows which titles you’ve read

From Googling to e-mailing to social networking, every day millions of Internet users unknowingly leave behind digital breadcrumbs while surfing the web, sometimes at the risk of compromising their anonymity. But while there’s technology available to stay anonymous in a time of surveillance, experts say policies and legislation won’t protect us from privacy invasion or being attacked in cyberspace.

As a medium, the Internet has allowed its users an unprecedented level of anonymity. Usernames and avatars hide names and true identities in online forums and communities, and anyone can choose how much to disclose to others in cyberspace. However, while most understand how posting personal information could have severe consequences, very few realize their online activity can be monitored and cross-referenced to reveal clues about their identity.

It’s important to think about every time that you interact with a third party online, they have information about you. You may buy your books online–lots of people buy things online. It’s not just social-networking sites where we volunteer this information; we volunteer it in a lot of ways.


Take the simple task of doing a web search, for example. In 2006, The New York Times reported how
leaked records from AOL revealed how users’ search-engine queries could be linked to their identities. By collecting and analyzing a user’s web searches, AOL’s researchers peeled away the many layers of cyber anonymity, unveiling the identity of user No. 4417749: Thelma Arnold, a 62-year-old widow who lived in Lilburn, Ga.

During a three-month period, Arnold typed into AOL’s search engine sentences such as “60 single men,” “landscapers in Lilburn, Ga” and “tea for good health,” clues that led AOL researchers to her. Commenting on AOL’s practice of storing users’ information, Arnold said to The Times, “We all have a right to privacy … Nobody should have found this all out.”

Search engines are just one of many places that–unknowingly to most–track users’ activity. Traveling through cyberspace, you provide information to others almost every click of the way, including to the ISP that knows your IP address, the browser that tracks which sites you’ve visited, and the cookies that store login or registration identification and user preferences.

How you read and gather information can be very sensitive. People often go on an intellectual journey where they really discover and explore fringes of political thought or other thoughts. It’s not hard to imagine a young person reading up about homosexuality, for example, if they have questions of their sexual orientation. That’s something that’s far from illegal but something they don’t want the world to know.

However, while anonymity allows people to express themselves freely without the fear of retaliation or persecution, there is always a darker side to it: It breeds criminal behavior.

From phishing and spam to botnets and DDoS attacks, global crime rings have been able to form in an environment that fosters concealment. While anonymity in cyberspace is “generally a good thing,” one imminent problem is how criminals are using it in combination with the borderless nature of the Internet to develop international crime rings.

Cyber crime is an international problem and the lack of true authentication leads many to fall victim to scams–419 advance fee frauds, for example. Criminals can freely and openly do business via web forums because they are able to cloak themselves.

As the majority of today’s cyber threats are profit based, criminals don’t want to be caught or have their businesses hampered, either by law enforcement or by competitors, so almost all cyber threats work to be untraceable. Compromised computers act as proxies and/or illicit bulletproof hosting is used to mask true sources. Unless serious investigations are made, at best, most cyber threats can only be traced to a proxy.

The future may bring a realignment of the Internet and its network of networks–untrustworthy networks that provide cloaking for criminals may be disconnected. Businesses that are attacked from anonymous sources may well decide to pull out of those countries that allow for such attacks to [be] carried out. Google is now a prominent example of this.

Top 10 Facebook and Twitter security stories of 2009

Social Networking Hacks

Facebook and Twitter was highly in news throughout 2009, and naturally the social networking sites became magnets for hacker attacks and sparked other types of privacy concerns. CIOs have expressed doubts about the social networking sites, and these stories show there is good reason to be worried. Here, in chronological order, are the top 10 security and privacy stories concerning Facebook and Twitter from the past year.

Jan. 6: Hackers hijack Obama's, Britney's Twitter accounts

Hackers gained control of more than 30 famous Twitter accounts, including those of Barack Obama, Britney Spears and Fox News. Twitter locked the accounts down quickly and restored control to their rightful owners, but not before the hacked accounts were used to send out nasty messages.

Twitter said the accounts were hacked into using the company's own internal support tools. The breach was considered serious enough that Twitter took the support tools offline until they were secured.

April 11: Twitter wrestles with multiple worm attacks

Worm attacks kept Twitter's security team busy for several days, as the site scrambled to identify infected accounts and delete rogue tweets. "Early on Saturday, April 11, the Mikeyy worm started to spread via Twitter posts by encouraging you to click on a link to a rival micro-blogging service StalkDaily.com," PC World reported. "As soon as you clicked on the link your account would be infected and begin to send out similar messages encouraging your followers to visit StalkDaily. Then your followers would become infected and the worm's infection rate would grow. You could also catch the worm by viewing infected profiles on Twitter.com."

Four attacks were launched between April 11 and 13, but no user account information was stolen.

May 18: Phishers, viruses target Facebook users

This headline could probably be written any day of any year, but we'll just pick a story from May, when identity thieves hit Facebook with phishing attacks designed to gain passwords for profit. Other examples from 2009: A password reset e-mail reported in October turns out to be a virus; again in October some hacked Facebook applications were leading users to fake antivirus programs; and in November hackers used a sexy photo of a woman to lure people to an attack Web site.

July 15: Twitter/Google Apps hack raises questions about cloud security

Twitter executives were victimized when a hacker obtained and distributed more than 300 confidential documents that concerned Twitter's business affairs and were stored on the hosted Google Apps service. Insufficient password strength seemed to be the root cause, and Twitter co-founder Biz Stone said Google was not to blame. The hacker reportedly also claimed to have compromised the Twitter accounts of co-founder Evan Williams, his wife and several employees. Williams denied this, but said his wife's e-mail account was compromised.

Aug. 4: High-profile organizations ban Facebook, Twitter

The U.S. Marine Corps formalized a ban on social networking sites such as Facebook and Twitter, saying "these Internet sites in general are a proven haven for malicious actors and content and are particularly high risk due to information exposure, user generated content and targeting by adversaries." The ban applies to Marine Corps networks, but does not prevent Marines from posting to social networks on their own time.

The Marines were not alone in taking such action. More than half of CIOs have completely prohibited use of social networks during company time, according to a Robert Half Technology survey of more than 1,400 CIOs from U.S. companies with at least 100 employees.

Aug. 6: Twitter victimized by distributed denial-of-service attack

Twitter was taken offline for two hours by a distributed denial-of-service attack, the first Twitter outage lasting longer than five minutes since June 16. Twitter continued to battle the distributed DoS attacks for several days, experiencing several more short outages. The same attack also targeted Facebook, but merely slowed the site down rather than taking it offline. The attack was reportedly politically motivated, and may have been related to the Russia-Georgia conflict. Politics may also have contributed to another Twitter outage on Dec. 18, in which a group called the "Iranian Cyber Army" claimed to take Twitter offline.

Aug. 14: Twitter used to manage botnet

A security researcher at Arbor Networks found that hackers were using Twitter to organize a botnet, the name given to a network of infected computers that does the bidding of bad guys who manage it.

"Botnet owners are continuously working on finding new ways of keeping their networks up and running, and Twitter seems to be the latest trick," the IDG News Service reported. "A now-suspended Twitter account was being used to post tweets that had links [to] new commands or executables to download and run, which would then be used by the botnet code on infected machines."

The account was suspended and investigated by Twitter's security team, but appeared to be one of a handful of similar malicious Twitter accounts.

Oct. 30: Facebook awarded $711 million in spammer case

Facebook used the legal system to fight back against a spammer who had gained access to user accounts, winning a judgment of $711 million against one Sanford Wallace. Wallace allegedly obtained login credentials for user accounts, and used those hijacked accounts to send spam that linked to phishing sites, sought to collect more Facebook account credentials, or linked to commercial Web sites that paid spammers for referrals.

"While we don't expect to receive the vast majority of the award, we hope that this will act as a continued deterrent against these criminals," Facebook said. Wallace may also face jail time.

Dec. 8: Facebook shuts down Beacon program, donates $9.5 million to settle lawsuit

Facebook found itself on the other side of the courtroom when plaintiffs filed a class action lawsuit alleging privacy violations in Facebook's Beacon program, which let third-party Web sites -- such as Blockbuster, Fandango and Overstock.com -- distribute "stories" about users to Facebook. Facebook did not admit to any wrongdoing, but ultimately agreed to shut the Beacon program down and donate $9.5 million to create a nonprofit foundation to promote online privacy, safety and security. The same week, Facebook also set up a new advisory board designed to improve user safety.

Dec. 9: Facebook unveils controversial new privacy settings

Facebook unveiled new privacy settings that it said were designed to give users more control over what information they share, but users reacted in anger after the overhaul led many to inadvertently expose content that was previously set to private.

"Great ? job. Now everyone who isn't even my friend can see my profile," one user complained.
Some of the problem came down to confusion over how to apply the new settings.


If used correctly, the settings do allow users to hide most of the content on their profiles. Still, the incident led to some negative attention for Facebook, and the site backtracked somewhat, making it easier for people to prevent others from seeing their friend lists. The story isn't over, as the Electronic Privacy Information Center has asked the Federal Trade Commission to investigate the changes in Facebook's privacy options.

10 Fool-proof Predictions for the Internet in 2020

Researchers expect more users, sensors. But will the `net be more secure?

Network World offers 10 “surefire bets” about what the Internet will look like in 10 years.

They include:
  1. As computer scientists work to improve the Internet's design, the global network is expected to change dramatically over the next 10 years. The Internet currently has about 1.7 billion users, but the U.S. National Science Foundation (NSF) expects the Internet will have nearly 5 billion users by 2020

  2. The Internet also will be more geographically dispersed in 10 years, spreading to more developing regions.

  3. Ten years from now, the Internet will be a network of things, not computers. Today, the Internet has approximately 575 million host computers, but the NSF expects infrastructure sensors alone to surpass the number of host computers by several orders of magnitude

  4. The Internet also will carry more content. Cisco estimates that global Internet traffic will increase to about 44 exabytes per month by 2012.

  5. In 2020, the Internet will be wireless. In the second quarter of 2009, the number of mobile subscribers hit 257 million, representing an 85 percent increase year-over year for high-speed data networking technologies. By 2014, approximately 2.5 billion people will subscribe to some form of mobile broadband, according to Informa.

  6. More services will use cloud computing. The NSF is encouraging researchers to develop better ways to map users and information in a cloud-computing infrastructure.

  7. Ten years from now, the Internet also will be greener. Future Internet architecture needs to be more energy efficient, as the amount of energy used by the Internet doubled between 2000 and 2006, according to the Lawrence Berkeley National Laboratory.

  8. Network management will be more automated in 2020. The NSF is researching new network management tools for the future Internet, including automated reboot systems, self-diagnosis protocols, finer-grained data collection, and better event tracking.

  9. The Internet will not rely on constant connectivity. Researchers are studying communication techniques that can handle delays or easily forward information to different users.

  10. The Internet will attract more hackers, and computer scientists will work to make it more secure.

Firefox Tops Vulnerability List

New study places Firefox at the top of vulnerability list for for the first half of 2009

Application security vendor Cenzic today released its security trends report for the first half of 2009 application. In it, Cenzic claims that the Mozilla's Firefox browser led the field of Web browsers in terms of total vulnerabilities.

According to Cenzic, Firefox accounted for 44 percent of all browser vulnerabilities reported in the first half of 2009. In contrast, Apple's Safari had 35 percent of all reported browser vulnerability, Microsoft's Internet Explorer was third at 15 percent and Opera had just six percent share.

The 2009 figures stand in contrast to Cenzic's Q3/Q4 2008 report, where IE accounted for 43 percent of all reported Web browser vulnerabilities and Firefox followed closely at 39 percent.

Microsoft issues rare security warning

Hackers are launching attacks against an unpatched vulnerability in the Microsoft Video ActiveX Control

Microsoft has released an out-of-band, emergency security advisory and also investigating attacks targeting a vulnerability in Microsoft Video ActiveX Control that could allow a hacker to gain complete control of a system. This news is already making headlines in Information Security world.

An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. When using Internet Explorer, code execution is remote and may not require any user intervention. At this stage, no security patch has been made available by Microsoft.

In this security advisory, Microsoft workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

• Prevent Microsoft Video ActiveX Control from running in Internet Explorer - See Microsoft
Knowledge Base Article 972890 for information on how to implement this workaround automatically.

Popular IT news website,
eWeek has already confirmed that:

"Hackers are launching attacks against an unpatched vulnerability in the Microsoft Video ActiveX Control that could allow an attacker to take full control over the system. When using Internet Explorer, code execution is remote and requires no user interaction, Microsoft says."

here to read the news on eWeek and refer here to read article on ComputerWorld, who claims Microsoft may have known about critical I.E bug for months.

The unpatched vulnerability in the Video ActiveX control that Microsoft has warned about was reported to the company in 2008, but one of the security researchers who found it refused to criticize Microsoft's response to the threat.

The bug was uncovered by researchers Alex Wheeler and Ryan Smith, who at the time both worked at IBM's ISS-X-Force. A Microsoft spokesperson said the company first learned of the vulnerability in 2008 and immediately began an investigation.

Joomla! Security / Vulnerability Scanner

Detect vulnerabilities on target Joomla! website...

I stumble across another cool scanner from yegh community. A regularly-updated scanner that can detect file inclusion, sql injection, command execution vulnerabilities of a target Joomla! web site. It's handy utility to check your website after designing on Joomla! platform.

If you are not aware - Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone.

Web Trackers Systematically Compromise Users' Privacy

Website monitoring practices take advantage of many loopholes in privacy regulations

A University of California, Berkeley study found that Web users may be tracked by dozens of sources on a visit to a single site. Within a single month, the researchers found 100 monitoring agents on the site blogspot.com. Although many of the trackers used on blogging sites are low-level monitors used by bloggers to see who is reading their posts, major companies also are tracking a significant amount of Web traffic, according to the report.

The researchers found five trackers operated by Google, including Analytics, DoubleClick, AdSense, FriendConnect, and Widgets. "Among the top 100 Websites this project focused on, Google Analytics appeared on 81 of them," according to the report. When combined with the other trackers it operates, Google can track 47 of the top 50 Web sites, and 92 of the top 100 Web sites. The researchers note that even if Web users know that their online activities are being tracked, they have no way of knowing how that data is being used. The report says that 36 percent of the Web sites in the study openly acknowledge the presence of third-party tracking, but each of the sites also state that the data-collection practices of the third parties are outside the coverage of the site's privacy policy. "Based on our experience, it appears that users have no practical way of knowing with whom their data will be shared," the researchers report.

The researchers note that many large companies have hundreds or even thousands of affiliates, sometimes in completely different industries, and occasionally in foreign countries. Please refer here to read this interesting research and report on DarkReading.

Why Wikipedia is not yet trusted for source of information?

Parents warned of Wikiporn risk

Parents have been warned not to let children use the website Wikipedia unsupervised after an entry on a popular children's book was edited to contain pornographic material.

Sexual and violent acts between characters were added last week to the online plot summary for Mrs Frisby And The Rats Of NIMH, which is recommended for students in years 5 to 9. The edited page for the book, on the list for the Premier's Reading Challenge, was visible for about an hour before it was changed to the original text.

A Sydney mother was shocked to discover the article, after researching the book for her son. NSW Parents Council executive officer of communications, Michelle FitzGerald, said "all parents" should be concerned. It is a concern to the council that the internet, if used inappropriately or not supervised, can lead children into areas where they really should not be.

Wikipedia's Australian representative, Brianna Laugher, said vandalism was an continuing problem for the site."Wikipedia, in general, is not designed for a primary school audience," she said. "I don't advise any children to use it before they have had the pitfalls explained to them."

A NSW Education Department spokesman said the school attended by the woman's son had not advised students to use Wikipedia as a research tool. "The department has filters to block inappropriate material on websites being accessed from school computers."

But website expert Mat Hardy, who is doing a PhD on the use of Wikipedia in education, said filters generally worked on a domain basis and would not block sites like Wikipedia. The website used a program called a "bot", which automatically detects certain triggers, such as profanity or major edits. "If [the edited article] was only up for an hour or so, that demonstrates how robust the system is, even though that is one of the most obscure articles," Mr Hardy said.

Gazelle Browser Offers Better Security ?

Researchers Say Gazelle Browser Offers Better Security

Researchers at various universities are working with Microsoft Research to develop a more secure Web browser code-named Gazelle. The researchers recently demonstrated Gazelle on Windows Vista and with Internet Explorer's Trident renderer, and have also published a paper describing the project. Gazelle uses a browser-based operating system, a browser kernel that consists of approximately 5,000 lines of C# code and can withstand memory attacks. No existing browsers, including new architectures like IE 8, Google Chrome, and OP [another experimental browser], have a multi-principal OS construction that gives a browser-based OS, typically called browser kernel, the exclusive control to manage the protection and fair-sharing of all system resources among browser principals.

A team consisting of Microsoft Research personnel and university staff members has demonstrated a potentially more secure Web browser called Gazelle. A paper (PDF) describing the browser prototype was published at Microsoft Research Thursday.

However this research team, led by Helen J. Wang and others, appears to be doing work that's separate from Microsoft's Internet Explorer 8 team. IE8 and Google Chrome frequently appear in the paper as examples of browsers that get security wrong.

The principals, or Web sites, communicate with each other by passing messages through the browser kernel, which manages security and the sharing of system resources. The browser uses separate processes to run a Web page and its embedded principals. Still in the prototype stage, Gazelle is slow because of its level of overhead, and the team also will have to address the browser plug-in issue.

Hackers able to fool browsers into redirection

Adobe warns of 'clickjacking' attacks

Adobe has issued a security alert about its Flash software that makes it vulnerable to being abused by hackers in a practice known as clickjacking. Clickjacking involves subverting a web page so that when a visitor clicks on a link they are redirected to a site the hackers wants them to see. It is a variant of cross-site scripting attacks but appears to be more serious.

The details of the attack were due to be published at the OWASP NYC AppSec 2008 Conference but the talk was withheld at Adobe’s request until a workaround could be developed.

“Let’s be clear though, the responsibility of solving clickjacking does not rest solely at the feet of Adobe as there is a ton of moving parts to consider,” said Jeremiah Grossman, co-founder of Whitehat Security and one of the researchers who uncovered the technique.

Clickjacking - should you be worried?

Nearly all browsers are vulnerable to this new attack class, but details are scarce

Worth reading Q&A on clickjacking:

Excellent explanation by Schneier:
In plain English, clickjacking lets hackers and scammers hide malicious stuff under the cover of the content on a legitimate site. You know what happens when a carjacker takes a car? Well, clickjacking is like that, except that the click is the car.
"Clickjacking" is a stunningly sexy name, but the vulnerability is really just a variant of cross-site scripting. We don't know how bad it really is, because the details are still being withheld. But the name alone is causing dread.
