Consumer modems are blamed for the rise in open recursive DNS servers
Internet security experts say that misconfigured DSL and cable modems are worsening a well-known problem with the Internet's DNS (domain name system), making it easier for hackers to launch distributed denial-of-service (DDoS) attacks against their victims.

US$30 will buy a one-day DDoS attack now
Cyber-crime just doesn't pay like it used to.
Security researchers show lightweight, host-based access-control scheme that dumps attack packets without overwhelming memory, CPU
Researchers have come up with host-based security software that blocks distributed denial-of-service attacks without swamping the memory and CPU of the host machines.The filtering, called identity-based privacy-protected access control (IPCAF), can also prevent session hijacking, dictionary attacks and man-in-the-middle attacks, say researchers at Auburn University in their paper, "Modeling and simulations for Identity-Based Privacy-Protected Access Control Filter (IPCAF) capability to resist massive denial of service attacks."
But an error message may have been caused by a technical glitch

Evidence suggests the attack is politically motivated and aimed at silencing a Georgian activist
More than two days after experiencing a complete outage as a result of a distribute denial-of-service (DDoS) attack, Twitter and other social networking sites such as Facebook are still battling a surge in traffic related to the attack. Twitter has taken some steps to mitigate the spike in traffic and ensure that the site is not knocked offline again, but some of those steps are having an impact on third-party tools that link to Twitter through API's (application programming interface).

Analysis contradicts assertions made by some governments of North Korean involvement
The U.K. was the likely source of a series of attacks last week that took down popular Web sites in the U.S. and South Korea, according to an analysis performed by a Vietnamese computer security analyst.
