Symantec brags in a February 12 press release that it identified the infamous Slammer worm hours before it attacked computers around the world. Now security experts are angry that Symantec did nothing to avert its spread.
Jeff Johnstone says: "This was not prior knowledge of a bug or exploit, but was knowledge of a pending worldwide attack on the infrastructure of the Internet. That type of information is always shared among peers within the security community."
People subscribing to Symantec's DeepSight Threat Management System were made aware of the worm hours before it crippled much of the Internet. Telecommunications systems and ATMs were affected. However, there are those who dispute Symantec's claim. http://www.wired.com/news/infostructure/0,1377,57676,00.html
