In a recent NY Times article, some of the elite hackers are taking advantage of the real-time Web. These hackers have released the next generation of Trojans which uses a Twitter-like stream to channel information back to the hacker in real-time.
The ability to report back in real-time allows hackers to get around roadblocks such as RSA’s SecureIDs, temporary one time passwords. By sending this temporary password back to the hacker immediately, it allows them to sign onto your account.
Joe Stewart, the director of malware research for SecureWorks, recently decoded a particularly nasty Trojan that uses a real-time technique called Clampi, which is used to attack people who have access to corporate bank accounts with large balances.
This Trojan is being unknowingly downloaded through people going to hacked websites that download the code onto your machine. Clampi can take advantage of a vulnerability in Windows and spread itself to all of the computers on a corporate network. Mr Stewart found that all the infected machines were coded to notice when the user visits any of 4,600 Web pages, including banks and brokerage sites.
Clampi then transmits a real-time stream of user actions using instant messaging-like software. Hackers would log into the bank account and initiate wire transfers, funneling them through accomplices or fake employees.
What can you do to limit your chances of getting one of these Trojans? One way to keep your computer clean of malware by avoiding suspicious e-mail attachments and Internet downloads. Also, keep your antivirus definition up to date. When a new piece of malware is discovered, AV companies add it to their list of checks.
