Version Summary:

The BlackHole Exploit Kit framework may indicate ongoing exploitation.

 

Description
 

The BlackHole Exploit Kit is a malware distribution framework that allows attackers to generate exploits for vulnerabilities in an effort to install malicious software on users' systems when the users visit compromised websites.  The kit generates exploits for browser vulnerabilities pertaining to Adobe and Java components on Windows and Mac platforms.

While the software may be used for testing purposes, the presence of the software on user systems or on the network may indicate malicious activity.

Users are advised not to open e-mail messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in e-mail messages are safe, they are advised not to open them.

Administrators may consider disabling JavaScript in the vulnerable applications.
