Summary

A file or program contains an exploit that can take advantage of a known vulnerability to gain unauthorized access or control of a program, device or service.

Technical Details

An exploit can be any object - for example, a program, a piece of code, or even just a string of characters - that can take advantage of a flaw or loophole in a program or operating system (a vulnerability).

An exploit is usually maliciously used to gain unauthorized access, or to force a vulnerable program or operating system to perform unexpected actions.

The name of the detection that identified the exploit will often indicate the vulnerability it targets, such as:

  • Exploit.Java.CVE-2012-0507

Where CVE-2012-0507 is the name used by the CVE - Common Vulnerabilities and Exposures (CVE) organization to identify the vulnerability.

Distribution

Exploits are often included in harmful programs such as trojans or worms, to facilitate their other destructive actions. These programs are usually spread in email attachments, or as disguised files that are distributed over networks.

Exploits are also used by exploit kits, which are most commonly encountered on compromised webpages. While an unsuspecting user views the webpage, the kit silently probes their computer or device for any flaws that can be exploited.

Impact

Exploits allow an attacker to perform a wide range of possible actions on an affected device, from viewing data on a restricted-user database to gaining almost complete control of a compromised system. For examples of exploits on various platfoms, see the following descriptions:
