Technical Details

Majava Generic Detections identify, among other things, malicious files that exploit known vulnerabilities in the Java Runtime Environment (JRE) to gain access and control of the system.

If successfully used, exploits can provide an attacker with a wide range of possible actions, from viewing data on a restricted-user database to almost complete control of a compromised system.

The exploit files may be delivered by other malware, such as the Blackhole exploit kit.
