The Blackhole exploit kit
The exploit file is delivered by the highly-prevalent Blackhole exploit kit, a utility program used by attackers to silently install their malware onto a user's computer during a drive-by download attack.
The exploit kit is typically hosted on a short-lived webpage, and victims are driven to these pages by either hijacking traffic from a legitimate, compromised website, by redirecting traffic from search engines using Search Engine Optimization (SEO) poisoning, or through malicious links in spam emails.
Once a visitor is on the malicious page, the exploit kit silently probes the visitor's computer system for vulnerabilities in specific applications (in some cases, specific versions of these applications). Targeted applications include Java Runtime Environment, Media Player, Adobe Flash Player and Adobe Reader, and specific Windows components.
If found, the kit automatically exploits the vulnerabilities and downloads additional files (the kit's payload) onto the victim machine. The files downloaded by Blackhole onto the victim machine are usually other known malware, including:
