Swedish teenager a menace

The ACM summarizes a report from the NY Times.

A 2004 penetration of a Cisco Systems network … [appears] to be one salvo in an extensive series of breaches that demonstrate how easy it is for even sophisticated Internet-connected computers to be compromised. … Surveillance software installed on the University of Minnesota computer network by security investigators last May revealed the network was being used to launch hundreds of Internet attacks, and about half of more than 100 attempted break-ins over a two-day period were successful. A nearly year-long probe into attacks on computer systems … has yielded a Swedish teenager as the primary suspect.

Imagine what trouble we would be in if someone were serious about this.
