Warning: Pirated Windows 7 uses Trojans to build botnets

For Microsoft's upcoming Windows 7 operating system, attackers have released pirated Windows 7 systems that incorporate malware versions and have been working hard to build botnets.

According to researchers at the Damballa Institute, the attacker hid a Trojan horse program on the pirated Windows 7 operating system and then began circulating the pirated operating system on the BT website. The Damballa report indicated that they had closed some botnets on May 10 and removed botnet control of the server, but the current infection rate has risen to 552 users per hour.

Tripp Cox, vice president of the Damballa Institute, said, "This pirate system package was released around April 24th. We estimate that this botnet has successfully executed at least 27,000 before we shut down its controls and commands." Secondary installation. ”

Attacking users with pirated software is no longer a new hacking tool. As early as 2008, attackers tried to build Mac botnets for user-supported iWork’09 and CS4 pirated system software.

In addition to the threat of malware attacks, privacy is the main target of attackers. A joint report by the BSA (Business Software Alliance) and IDC showed that in 2008 software companies lost about 50 billion in privacy.

The pirated Windows 7 RC version of the Trojan horse that was circulated on the BT website, whenever users download the software, will try to install other malware on the infected computer. It is very difficult to prevent the infection from spreading, because many anti-virus software does not currently support Windows 7 systems. The operating system is already infected before these anti-virus tools can be installed.

 This malware installation is still spreading at a rate of 1600 per day," Cox said. "After the botnet was cut, no operations on this pirated Windows 7 RC could be entered." The botmaster, and the previously installed pirated software is accessible, the highest infection rates are currently in the United States, the Netherlands and Italy. ”
