Summary

Exploit:Java/Majava.C identifies malicious files that exploit vulnerabilities in the Java software platform.

Security programs use generic detections that look for broad patterns of code or behavior to identify similar programs or files. If you suspect the file was incorrectly detected, go to: Removal: Suspect a file is incorrectly detected (a False Positive)?.

Removal

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

Exploit:Java/Majava.C is a generic detection that identifies exploit files used to target and exploit vulnerabilities in the Java software platform, including the recently reported CVE-2013-0422 vulnerability in Java 7 Update 10.

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.
