Is there life after death? If you're malicious HTML code, there might be.
"Researchers at Finjan Software Inc. say they have uncovered several instances in which malware from previously disabled Web sites or pages has reappeared, served up by caching systems that don't recognize the trouble.
When the cached pages are served up, they carry with them whatever malware may have been attached to the original page via HTML or JavaScript. This malware can be used to install spyware or Trojan horses, even after the threat has supposedly been eradicated.
Finjan advises enterprises and ISPs that use caching servers to perform periodic checks of their cached content using proactive, behavior-based security software."
