Exploit:JAVA/CVE-2010-4454 Is back and can bypass Malware Bytes firewall and Microsoft Security Essentials fire wall.

Running Malware Bytes full scan revealed nothing. Running Microsoft Security Essentials full scan did find the Trojan and removed it.

Sends out spam emails out using your email address--screws up the operation and speed of your computer also.

I notified Malware but they said to put it on this forum site and I don't know what good that will do because the owners of this malicious malware as learned how to bypass the new firewalls so this is something the Security division is going to have to fix

MBAM and MSE are not Firewall applications.

Firewall applications are software or on appliances used to block sites and TCP and UDP protocols based upon rules based criteria.

MBAM doesn't target .CLASS files and doesn't extract files from Archive files such as; RAR, ZIP, LZH, 7z, CHM, etc.

Malicious .CLASS files are Java and exist in Java Jars which are ZIP files but with the extension.JAR.

What do you mean "I notified Malware " ??? That doesn't make any sense.

The Java exploit code represented in the detection "Exploit:JAVA/CVE-2010-4454" means that a web site was hosting a malicious Java Jar that exploits CVE-2010-4454 and is usually associated with what is called the "Black Hole Exploit Kit". The Black Hole Exploit Kit is a set of software someone with malicious intent can use to put on a web site to get you infected. The web site could be setup deliberately to be malicious or could be a legitimate site that was compromised that has had code placed on the server to redirect you to a site deliberately being malicious. It could be a site you visit or a site sent to you in email.

Right off the bat when you look at the vulnerability name "CVE-2010-4454" one can tell this vulnerability was found in 2010. That means there is a strong likelihood that an updated version of Oracle Java was released to mitigate this vulnerability.

The Black Hole Exploit Kit uses multiple vulnerabilities searching for one your computer that not been patched yet. This includes Adobe PDF, Adobe Flash and Oracle Java. What this means is that not only must you make sure the OS your computer runs is up-to-date in all patched but you must make sure ALL the software on your PC must be up-to-date. For example the latest Adobe Reader is v10.1.2 and Oracle Java is at version 7 update 3 (or version 6 update 31) . If those software reside on your computer and is an older version then your PC is not up-to-date leaving your computer "At Risk" to such malicious activity as the Black Hole Exploit Kit.
