Note: It seems that client-side vulns are all the rage and tossing out the term 0-day in vogue, so anything my readers can do to ensure this list is accurate is appreciated. I am looking for vulnerabilities that were identified after finding active exploits (not PoC code).

18 total since 1988. One third of them in 2006. Hmm.

Honorable Mention (which don’t quite make the list because the vulnerability information was not discovered due to an active exploit):

• RealServer ../../../ overflow
• Any of the Immunity VSC releases (Mac OS X Kernel Local, anyone?)
• Samba bug that HDM got hacked with… [this may get elevated, I am not sure]
• [Credits: Dave Aitel and Anton Chuvakin for the information]

Definitions:

Undercover Vulnerability: A vulnerability that was generally unknown (e.g. not published on any lists, not discussed by "above ground" security folks) until it was actively exploited in the wild. The vulnerability was discovered through evidence of tampering or other means, not through the usual bugfinding ritual.

Undercover Exploit: The event and/or code used to compromise a resource running the vulnerable software in the wild.

*Note: the "credit" given is not to the person who discovered the exploit/vuln, but to the person who pointed me in the right direction. Thanks, all.
