U.S. intelligence officials increasingly fear that computer hackers could wreck banks and large financial institutions, or send stock markets into one more panicked frenzy, by covertly manipulating data and spreading false information.

Hackers in Austria have developed a variety of methods for hacking or jamming surveillance cameras.

Web sites in China are being used heavily to target computer networks in the Defense Department and other U.S. agencies, successfully breaching hundreds of unclassified networks, according to several U.S. officials.

A spat between rival computer worm writers has escalated into a
destructive free-for-all, with an assortment of worms infecting
thousands of computers worldwide and disrupting several high profile

Recent technological advances in so-called genetic circuits have brought closer a world where cells and viruses could be modified to more effectively serve humans, but also have raised concerns that programmable life could lead to a host of tailored threats similar to Internet worms.

The U.S. military has assembled the world's most formidable hacker posse: a super-secret, multimillion-dollar weapons program that may be ready to launch bloodless cyberwar against enemy networks -- from electric grids to telephone nets.

Design automation systems tailored to the task of genetic engineering could prove to be double-edged tools. While they represent a central thrust of the emerging synthetic biology movement, they also can lead to the accidental or deliberate creation of pathogenic biological components.

The author muses on the possibility of genetic engineering going "open source" and the risk of bio-hackers.

Biologists are crafting libraries of interchangeable DNA parts and assembling them inside microbes to create programmable, living machines

Researchers uncovered a serious flaw in the underlying technology for nearly all Internet traffic, a discovery that led to an urgent and secretive international effort to prevent global disruptions of Web surfing, e-mails and instant messages.
