Internet Service Providers are in the perfect position to kill vast armies of compromised computers -- or bots -- that are being used by cyber-criminals to launch the majority of spam and phishing attacks, according security specialists at the AusCERT 2006 conference.
After analysing traffic from 68 ISPs around the globe, a security researcher claims that as much as five percent of all Internet traffic is from DDoS-attacks.
Thanks to bots and the rise of financially-driven cybercrime, the menace of distributed denial-of-service (DDoS) attacks are too real to ignore -- defending against such attacks however is driving collaboration between ISPs and top tier telcos to push security to the cloud.
China leads Asia in malicious online activity, racking up 42 percent of the action in the first half of 2007, up from 39 percent last year.
Authorities are cracking down on phishing and botnets, but the threats are advancing instead of diminishing, two law enforcement officials said.
Botnet operators have become public enemy number-one as consumers, businesses and governments fall foul to identity theft, DDoS attacks and spam. Yet no one appears to be able to stop the spread of bots -- except maybe the media.
If providers don't pitch in against the threat, customers might defect -- and the health of the Net itself could suffer.
