Schneier on Attack Trends: More Complex Worms
Gary W. Longsine writes "Bruce Schneier has posted an interesting entry on expected attack trends to his blog. Of particular interest is the increasing sophistication of automated worm-based attacks.

Trend Micro also has information on a scanning-capable version of this worm, which they call: WORM_SPYBOT.ID" -
Device Drivers Filled with Flaws, Pose Risk
Gary W. Longsine writes "Security Focus describes device drivers as an untapped source of buffer overflows, posing substantial risk not typically considered as part of a standard risk assessment.

A flaw in its random number generator seems to have protected 10% of the internet from the Witty worm."
