Webattacker is a do-it-yourself malware creation kit that includes scripts that simplify the task of infecting computers and spam-sending techniques to lure victims to specially rigged Websites. It was allegedly created by a group of Russian programmers. The kit demands minimal technical sophistication to be manipulated and used by crackers.
Sophos has reported that WebAttacker is being sold at some hacker Web sites or through a network of individual resellers and includes technical support. The malware code is currently being delivered in at least seven exploits, including threats aimed at Microsoft's MDAC software, Mozilla's Firefox Web browser and Sun Microsystems's Java virtual machine programs.
The exploitation process usually consists of the following steps:
- Establishment of a malicious website though automated tools provided by WebAttacker
- Sending mass email (otherwise known as spam) inviting the recipient to visit the website under various pretenses
- Infecting the visitor's computer with a Trojan by exploiting numerous vulnerabilities
- Using the Trojan to run arbitrary executables on the infected PC which are typically designed to extract passwords, personal information, keystroke logging, or taking general control over the compromised computer
WebAttacker exploitation technique is currently based on the following vulnerabilities:
- Microsoft Security Bulletin MS03-011
