TrojanDownloader:JS/Qakbot.G is a JavaScript trojan that attempts to download and install Backdoor:Win32/Qakbot.gen!A.

Exploit:Java/CVE-2010-0840.KI is the detection for an obfuscated Java applet trojan that exploits a vulnerability described in CVE-2010-0840. Successful exploitation may lead to the download and execution of arbitrary files within the user's security context.

Exploit:Java/CVE-2010-0840.MB is a detection for malicious Java applets that exploit the vulnerability described in CVE-2010-0840. Successful exploitation may lead to the downloading and execution of arbitrary files under the user's security context.

Exploit:Java/CVE-2010-0840.NZ is a variant of the Exploit:Java/CVE-2010-0840 family - a detection for a malicious Java applet stored within a Java Archive (.JAR) that attempts to exploit a vulnerability in the Java Runtime Environment (JRE) up to and including version 6 update 18. The vulnerability allows an unsigned Java applet to gain elevated privileges and potentially have unrestricted access to a host system outside its "sandbox" environment. It is discussed in CVE-2010-0840.

Exploit:Java/CVE-2011-3544.T is a malicious Java applet stored within a Java Archive (.JAR) file. It attempts to exploit a vulnerability in the Java Runtime Environment (JRE) component in Oracle JAVA SE JDK and JRE 7, 6 Update 27 and earlier. The vulnerability allows an unsigned Java applet to gain elevated privileges and potentially have unrestricted access to run arbitrary Java code outside of the "sandbox" environment.

More information about the vulnerability is available in the following articles:

• CVE-2011-3544
• Oracle Java SE Critical Patch Update Advisory - October 2011

Exploit:Java/CVE-2011-3544.AV is a detection for a malicious Java applet stored within a Java Archive (.JAR) that attempts to exploit a vulnerability in a Java Runtime Environment (JRE) component in Oracle, JAVA SE JDK and JRE 7, 6 update 27 and earlier. The vulnerability, discussed in CVE-2011-3544, allows an unsigned Java applet to gain elevated privileges and potentially have unrestricted access to run arbitrary Java code outside of the "sandbox" environment.

Exploit:Java/Blacole.ES is malicious Java code that exploits a vulnerability that allows the execution of arbitrary code. The vulnerability is further described in CVE-2011-3544; successful exploitation may lead to remote code execution.

Exploit:Java/CVE-2011-3544.gen!D is the generic detection for a obfuscated malicious Java applet stored within a Java Archive (.JAR) that attempts to exploit a vulnerability in Java Runtime Environment (JRE). The vulnerability, discussed in CVE-2011-3544, allows an unsigned Java applet to gain elevated privileges and potentially have unrestricted access to run arbitrary Java code outside of the "sandbox" environment.

Exploit:Java/CVE-2010-0840.QG is a malicious and obfuscated Java class that exploits the vulnerability described in CVE-2010-0840. Successful exploitation may lead to the downloading and execution of arbitrary files under the user's security context. When a user visits a website that contains this malicious Java class using a computer that has a vulnerable version of Java, security checks may be bypassed, which allows arbitrary code execution.
