ATM Fraud: New Skimming Scheme Hits Banks
A series of skimming crimes that hit the Nashville, TN area recently is but one of many ATM fraud schemes preying upon financial institutions and their customers.
Nashville police reported last week that they were investigating an ATM card skimming scheme where at least 600 individuals were potential victims. Investigators say five Bank of America ATMs were hit, as well as an unknown number of US Bank machines. A total of 60 people had fraudulent withdrawals from their accounts for anywhere between $100 to $5,000 dollars. Investigators suspect that the skimming schemers have now moved on to other cities.
Among recent incidents:
In Las Vegas, 75 skimming attacks were reported over a three-month period, as compared to previous rates of 2-3 incidents per year.
In Sydney Australia, the New South Wales Fraud Squad reported 60 skimming attacks in the first four months of 2009, with a spokesman saying the devices used are "becoming smaller, more sophisticated and capable of storing more data."
In California, investigators reported that skimmers and card duplicators could be bought from overseas sellers on the Internet for a few thousand dollars.
Card skimming is not new. Early forms of skimming device and even dummy ATMs installed in empty shop fronts were used to capture card information in the 1990s.
The ATMIA recommends these steps to help prevent ATM fraud:
Build awareness among customers, branch employees and ATM service teams to help detect devices added to ATM exteriors. Visual clues include tape residue near or on a card reader that would show a skimming device had been placed on the ATM.
Chip-based cards house data on microchips instead of magnetic stripes, making data more difficult to steal and cards more difficult to reproduce.
Contactless cards, out-of-band authentication using cell phones and biometric readers are all new authentication technologies that can be used as alternate methods for conducting secure ATM transactions.
Alert systems monitor routine patterns of withdrawals and notify operators or financial institutions in the event of suspicious activity.

Second Windows 7 activation hack appears
Windows 7 has been available on Bittorrent sites pretty much from the get go. Most of the torrent ISOS available right now are already cracked, bypassing entirely the need to enter a Windows 7 key. But that method involves using a script to hack in an OEM key, which allows Windows 7 — barring any surreptitious Microsoft updates — to run on any machine.
That’s working well enough for now, but hackers are always interested in trying to beat the same game from a different position, so a new Windows 7 activation hack has just shown up. It doesn’t require an OEM key at all. Instead, it simply bypasses the verification DLL completely.
It works by nuking the verifying sppcompai.dll from orbit, and even goes so far as to decativate any reminder popups that might otherwise annoy, reminding you indefinitely to activate your copy of Windows 7.
This is probably a short-lived hack, though. A similar activation hack came out for Vista a couple of years ago, and Microsoft was able to patch it up without much problems. According to My Digital Life, the reason the Windows 7 hack might work right now is “due to leniency… on the part of Microsoft on [the] activation mechanism to avoid getting too many false-positives.”
In other words, Microsoft’s just biding its time right now before dropping the hammer on this activation hack. The only question is, when they finally decide to do so, whether that’ll drop the hammer on the OEM hack as well.

Spam targets financial transfers
Social Engineering, Spam and Phishing attacks altogether targeting financial transfers
Experts have spotted a new spam attack that targets a financial transfer system handling trillions of dollars in transactions annually; it turns out it's yet another case of fake emails.
The spam messages pretend to come from the National Automated Clearing House Association (NACHA), a U.S. nonprofit association that oversees the Automated Clearing House system (ACH). ACH is a widely used by system used by financial institutions for exchanging details of direct deposits, checks and cash transfers.
In the last few months, countless businesses have lost money through ACH fraud. It happens when the hackers obtain the authentication credentials required to transfer money. Although NACHA has no direct involvement in the processing of the payments, spammers have launched a campaign with messages purporting to be from the organization saying that an ACH payment has been rejected.
The spam messages have a link to a fake website that looks like NACHA's. The site asks the victim to download a PDF file, but it is actually an executable. If launched, the file will install Zbot, also known as Zeus, an advanced piece of banking malware that can harvest the authentication details required to initiate an ACH transaction, according to M86 Security.
NACHA has put an advisory on its website, warning: "NACHA does not send communications to individuals or organizations about individual ACH transactions that they originate or receive."
With this kind of sophisticated trickery, the question becomes: How do you stop it? For starters, make sure you publicize the scheme and keep ACH clients well-trained to refuse emails even if they look real. And even if you are working in another business sector, pay attention to this story because spam could be targeting you next.

8 Hackers Indicted in $9 Million ATM Theft
Eight members a hacker ring that made off with more than $9 million in a massive ATM fraud scheme last November were indicted in an Atlanta, GA courtroom this week.
The eight men, all from eastern European counties, are accused of hacking into a computer system at RBS WorldPay, the U.S. payment-processing division of Royal Bank of Scotland Group. They then allegedly cloned prepaid ATM cards, which they used to draw out cash from 2,100 ATMs in 280 cities around the world within a couple of hours.
The 16-count indictment charges Tsurikov, Pleshchuk, Covelin and "Hacker 3" with conspiracy to commit wire fraud, wire fraud, conspiracy to commit computer fraud, computer fraud, access device fraud and aggravated identity theft. The indictment states the accused group used sophisticated hacking techniques to compromise the data encryption used by RBS WorldPay to protect customer data on payroll debit cards.
Igor Grudijev, 31, Ronald Tsoi, 31, Evelin Tsoi, 20, and Mihhail Jevgenov, 33, each of Tallinn, Estonia, were indicted for access device fraud.

Firefox Tops Vulnerability List
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.

AES - Cracked or Broken?
The Advanced Encryption Standard (AES) system was long believed to be invulnerable to attack, but a group of researchers recently demonstrated that there may be an inherent flaw in AES, at least theoretically.
The study was conducted by the University of Luxembourg's Alex Biryukov and Dmitry Khovratovich, France's Orr Dunkelman, Hebrew University's Nathan Keller, and the Weizmann Institute's Adi Shamir.
In their report, "Key Recovery Attacks of Practical Complexity on AES Variants With Up to 10 Rounds," the researchers challenged the structural integrity of the AES protocol. The researchers suggest that AES may not be invulnerable and raise the question of how far is AES from becoming insecure. "The findings discussed in [in the report] are academic in nature and do not threaten the security of systems today," says AppRiver's Fred Touchette. "But because most people depend on the encryption standard to keep sensitive information secure, the findings are nonetheless significant."
AirPatrol CEO Ozzie Diaz believes that wireless systems will be the most vulnerable because many investments in network media are wireless, and there is no physical barrier to entry. Diaz says that exposing the vulnerability of the AES system could lead to innovations for filling those gaps.
Touchette says that AES cryptography is not broken, and notes that the latest attack techniques on AES-192 and AES-256 are impractical outside of a theoretical setting.

Jailbroken iPhones fall victim to Australian virus
iPhone users who have jailbroken their handset to install third-party apps have fallen victim to a virus created by an Australian hacker that alters the phone's wallpaper to a picture of singer Rick Astley.
The hacker, Ashley Towns, a 21-year-old from Wollongong, south of Sydney, claimed the virus was a "harmless" practical joke.
The virus had spread to hundreds of iPhones nationwide by early yesterday and has since gone global.
It followed a similar virus in Germany where a hacker demanded users pay a fee of five dollars for its removal. But Towns was not demanding money from his version.
iPhone users flooded online forums including Whirlpool reporting the virus as early as Friday.

Smishing Attack is New Variation of Classic Fraud
Chase Bank customers in the New York metro area have been receiving bogus text messages claiming to be from the bank, asking for account information. A local New York television station reported the phishing attack last week, claiming that "tens of millions of dollars" have already been stolen by fraudsters.
Chase media relations spokesman Tom Kelly downplays the report, saying, "As you might expect, TV is a little breathless on an issue that has been around via email and now texts for a number of years." Kelly says this attack is a variation of phishing known as "smishing." He says the amount of money taken in the attacks or the number of customers receiving the text messages is unknown.
Lesson learnt:
The new variation of phishing knows as smishing. Don't trust any sms from unknown sources regardless - period.

Rogue Security Software Still Top Threat
Microsoft this week disclosed new evidence that the good guys may be getting the upper hand on cybercriminals -- at least some of the time.
Microsoft says it is seeing decreases in scareware, those obnoxious online promotions that try to frighten you into paying for worthless antivirus protection, along with a decline in those faked Flash player updates that actually download viral coding that allows the bad guys to take full control of your PC.
During the first six months of 2009, Microsoft's Malicious Software Removal Tool cleansed scareware infections from 13.4 million Windows PCs, down from 16.8 million in the last six months of 2008.
Additionally, Microsoft in the first six months of 2009 disinfected copies of the Zlob Trojan found on 2.3 million PCs, down from 21.1 million PCs cleansed of Zlob in the last six months of 2008 -- a 10-fold decrease.
And self replicating worms, like Conficker and Taterf continue to steadily infect more and more PCs. Both Taterf and Conficker spread via tainted USB flash drives.
The main way a PC gets infected is when a viral flash drive gets inserted into its USB port. The virus launches a program that looks for computers nearby sharing the internal network, and spreads the infection to those machines. As part of this loop, it corrupts all of the USB ports on each newly infected machine. So each freshly-infected PC gets primed to taint any clean flash drive that subsequently gets plugged into any of its USB ports. And the cycle repeats exponentially.
We need to ensure, we keep our anti-virus upto date, don't click on any links unless we are really sure, don't install untrusted softwares / applications and don't open any attachments. And we will continue to stay ahead of bad guys out there.

The pros and cons of switching to Windows 7
I'll also tell you three possible reasons for keeping the new OS on the shelf — for a while, at least.
I find a solid core of real improvements in the new release. There are many aspects of Windows 7 that cry out for adopting it and just a few that suggest sticking with Vista or XP.
- Windows 7 is easier on the eyes
Windows 7's a stunner. From wallpaper that changes itself to the tightly controlled group of icons in the area near the clock, Win7 puts the things you need most where you need them. The OS also moves the flotsam out of the way.
Since there's no Sidebar in Windows 7 — good riddance, I say — Win7's gadgets move to the high-rent district of the desktop, where you can move, resize, and snap them together neatly. - The Action Center puts all the nags in one place
Windows XP and Vista are notorious for scattering important information all over creation. At the same time — and quite perversely — every two-bit application you install on an XP or Vista PC can pop up annoying messages, distracting your attention while you're trying to get some work done.
Win7 reduces the shrill impositions to a minimum by funneling almost all interactions through the Action Center. Yes, the Action Center has its roots in the old Security Center, but it's all grown up now.
The Action Center serves as traffic cop for announcements that inform, warn, and often annoy. But rather than a pop-up window, the only alert you'll see is a flag in the notification area (near the clock) that turns yellow or red as needs dictate. - Win7's security is stronger and less intrusive
Security stuff gets complicated very quickly. Suffice it to say that Windows 7 is significantly more difficult to crack than Vista, which in turn was an order or magnitude tougher to break into than XP. (Internet Explorer and the .NET Framework are noteworthy exceptions.)
Compared to Vista's User Account Control (UAC), the equivalent in Windows 7 is clipped and reined in. You can get to the settings easily. For most people, security won't be nearly so difficult in Win7 as it was in Vista. - You can make a movie of what ails your PC
If you haven't seen Windows 7's new Problem Steps Recorder (PSR), you owe it to yourself to try it. Click Start, type psr, and hit Enter. This little utility lets you record everything on the screen — except the stuff you type — as it happens. When you're done, PSR spits out an MHTML file that can be opened and played back in Internet Explorer
Like the Snipping Tool in Vista (also available in Win7), once you try PSR, you won't know how you ever lived without it. - Search works — finally!
Windows XP's built-in search feature is a slow, painful, buggy joke. In Vista, search is a little less labored, occasionally usable, but still unreliable.
In Windows 7, Microsoft has, at long last, woven search into the operating system itself. There's no noticeable system overhead, searches proceed fairly quickly, and — most important of all — the results are accurate. - You get better control of your devices
Windows 7 centralizes control of all devices: printers, MP3 players, phones, keyboards, mice, fax machines, and anything else you plug into your computer. The controls all appear in a place called Device Stage.
If you're tired of having 10 different programs in 10 different places to control your attached hardware, those days are rapidly drawing to a close. The junky little programs that go with the devices will disappear, too. At least I hope they will. So long, commercial driver-update utilities! - Win7 Libraries beat out My Documents any day
While Libraries don't do away with the need to organize your files, they make it much, much simpler to track files and put them in the right locations.
"A place for everything, and everything in its place," With Windows 7 Libraries, file management is easier than ever. - HomeGroup makes sharing safe, fast, and fun
A stroke of pure design genius, Windows 7 HomeGroup bundles all the sharing options you'd likely want in order to make files, printers, and media accessible to any other Windows 7 PC on your network.
Despite these and other Win7 positives, there are at least three good reasons for Windows XP and Vista users to stick with their current OS:
- If your PC isn't up to snuff, fuhgeddaboutit!
While Windows 7's hardware demands are less stringent than Vista's, there are zillions of PCs that simply can't handle Win7. However, if you have a desktop machine or laptop that's more than a few years old, upgrading its hardware to support Windows 7 is likely more trouble than it's worth. Don't bother. - If your hardware or software demands XP, stick with that OS
The XP Mode built into Windows 7 Professional and Ultimate is a Virtual PC–based implementation of XP. XP Mode makes sense for large companies that want to get the benefits of Windows 7 but have to put up with hardware or software that runs only under Windows XP. - Don't try to fix what ain't broke
By far the most-compelling argument for staying with Windows XP or Vista is this: The Windows you have now does everything you need, and you aren't overly concerned about rootkits or other nearly invisible malware hosing your machine. In this case, there's no compelling reason to go out on a limb with Win7.
But in a small percentage of cases, the Windows 7 installation doesn't go well at all. As they say, stuff happens. Any upgrade could potentially become calamitous, and Windows 7 isn't immune.

5 New Technologies That Will Change Everything
Five new technologies are on their way that will give users unprecedented access to data thanks to new high-speed connections and user interfaces.
First, USB 3.0 is a new standard that preserves backward compatibility by allowing older cables to plug into new jacks, but features an extra pin that boosts the data rate to 4.8 Gbps. USB 3.0, dubbed SuperSpeed by the USB Implementers Forum, can transfer a 30 GB video in just over a minute.
Second, by 2012, two new wireless protocols--802.11ac and 802.11ad--should be able to provide over-the-air data transmissions of 1 Gbps or faster. The faster wireless data rate will enable users to stream multiple high-definition videos throughout a room or house.
Third, the next wave of next-generation TVs will allow viewers to experience three-dimensional (3D) videos at home. 3D TVs are likely to rely on alternating left-eye and right-eye views for successive frames. Many HDTVs already operate at 120 Hz, so the ability to alternate left and right eye images far faster than the human eye can see is already available. This type of 3D viewing will require glasses that use rapid shutters to alternate the view to each eye, but TV manufacturers also are working on 3D sets that do not require glasses.
Fourth, augmented reality in mobile devices will become increasingly popular as consumers expect to be able to receive information on any subject in any location. Researchers also are developing contact lenses capable of projecting images into someone's sight.
Finally, HTML5 promises to do away with browser conformity issues and the need for audio, video, and interactive plug-ins. HTML5 will enable designers to create Web sites that work the same on every browser and give users a better and faster Web experience.

Tracking Devious Phishing Websites
Internet security experts have discovered that many phishers are using a trick called a flux, which allows a fake Web site to rapidly change its URL, making it difficult for defenders to block phishing sites or warn unsuspecting users. New research has found that about 10 percent of phishing sites are now using flux.
Indiana University professor Minaxi Gupta says that because phishers often have access to thousands of hijacked machines they can quickly move a site around the Internet, protecting it from security professionals while keeping the fake site operational. To use a flux, phishers must control a domain name, giving them the right to control its name server. The phisher can then set the name server so it directs each new visitor to a different set of machines, rapidly cycling through the thousands of addresses available within its botnet. If the name server also is moved to different locations on the Internet, it is particularly difficult for defenders to pinpoint a central location where the fake site can be shut down.
There are some legitimate reasons for using a flux, but a legitimate flux looks different from a flux on a botnet. Shortening the detection time of phishing sites by even a few hours can make a major difference and make the scams less profitable for criminals.

Defeat keyloggers on unsecure computer terminals
Neo’s SafeKeys is a small program that helps to defeat keyloggers on unsecure computer terminals. It's is perfect for travel – use it in internet cafes, the office or even at home as protection against stealth keylogging programs that can be installed without your knowledge. It is a custom-made tool that allows for you to mouse-click your password on an on-screen keyboard.
Neo's SafeKeys 2008 displays a small window with a simulated keyboard on which you can type your sign-in, password, and other information. Neo's SafeKeys 2008 doesn't transmit information in a way that can be picked up by keyloggers. Nor does the program use the Clipboard. Instead, you type your info in the SafeKeys 2008 window and then drag the data to the appropriate text box in your browser.
Neo's SafeKeys 2008 successfully evaded the All In One Keylogger product in my tests. Other options help you foil keyloggers that regularly take screen captures to record your PC activities. According to the Alpin Software site, however, the utility's drag-and-drop methods don't work with all products — including the Opera browser.
No product will ever be able to guarantee your safety from snoops when you use a public computer. Here are the few advantages of Neo's Safekeys 2008:
- Unlike the Windows on-screen keyboard, Neo’s SafeKeys does not translate on-screen key presses to actual key presses (the Windows on-screen keyboard does not protect you against keyloggers)
- You don’t use your keyboard (keyloggers cannot record the password)
- The utility changes width and height each time, as well as its placement on the screen (to fool mouse-loggers, buttons will always be in different positions each time you use the program)
- Nothing is stored in the clipboard (clipboard loggers cannot save the password).
- You can use upper-case letters and symbols (such as !@#${}) by pressing the CAP button – no matter how complex your password is, the utility can type it.
I highly recommend all my readers to download Neo's Safekey 2008 and protect yourself from malicious programs such as Trojans/keyloggers, which can steal your confidential information.

Bank Dumped Customer Records
A local branch of M & T Bank in Rodgers Forge, MD was found to have tossed 52 customer records into a dumpster last week. The bank says the records were dumped inadvertently.
The exposure was revealed after a local news crew from an ABC affiliate went "dumpster diving" in the bank branch's dumpster and found the records.
M&T has contacted federal and state regulators about the breach and has issued new account numbers and free credit monitoring to the customers involved in the 52 records that were dumped. "We are conducting an extensive internal investigation, and at this point, it appears to be an isolated circumstance involving a single human error," Hosmer concludes.

Prototype Security Software Blocks DDoS Attacks
Auburn University researchers have developed a software filter that protects computers against distributed denial-of-service (DDoS) attacks without bogging down the computer's CPU and memory. The identity-based privacy-protected access control filter (IPCAF) also wards against session hijacking, dictionary attacks, and man-in-the-middle attacks.
Instead of warding against IP addresses, which can be faked by hijackers, IPCAF sends a user ID and password to computer users and the Web site they are attempting to access. Then the two parties create fake IDs and values for each packet so that each one is double-checked. Computers check the value in each packet and choose whether to accept it or not. Only then are more memory and CPU resources used to deal with them.
The researchers say that IPCAF also is useful because it does not rely on separate and expensive applications that bog down memory. Instead it uses servers and client machines without affecting computer use. IPCAF uses hash-based message authentication code to create the value it will use to confirm every single packet, which saves CPU power.
When testing IPCAF, Security researchers found that the computer network was only stalled by 30 nanoseconds during an attack through a 10Gbps connection.
