A chunk of Olympic themed targeted trojans

The world’s athletes and hackers now share a common focus – the Beijing Olympics. Whilst the athletes have a legitimate reason to concentrate on the Games, today’s hackers are using the 2008 Olympics for their own glory. MessageLabs today revealed new research showing the frequency and locations of targeted Trojan attacks and the tools used to avoid detection.

In the last six months MessageLabs has intercepted 13 separate Olympic themed attacks, across several different data-rich industries. With legitimate-sounding email subject titles such as “The Beijing 2008 Torch Relay” and “National Olympic Committee and Ticket Sales Agents”, some attacks purport to be from the International Olympic Committee, based in Lausanne Switzerland, however the reality is that all but one attack has been sent from an IP addresses within Asia Pacific.

Targeted Trojans are usually aimed at specific individuals within an organization with the purpose of infiltrating networks for corporate espionage. Each attack is usually small in numbers and often utilizes social engineering techniques, such as personalization, to persuade the recipient to open the email and attachment.

Hackers are constantly shifting to new delivery formats to hide the sinister malware and to avoid detection by traditional anti-virus engines, as well as using harmless and common attachment types which are not blocked. In these instances, Microsoft Office Database (MDB) files, usually hidden within a ZIP file, is one of the latest formats to be used. Once the MDB file has been downloaded the MDB exploit will drop an EXE file to the disk and steal data. MessageLabs predicts that in the coming year hackers  will vary their use of formats even further with 1 Byte XOR Key, Multiple XOR keys and ROR, ROL, ADD and SUB formats to be exploited.
