Malware potency increases as numbers drop

Global malware outbreaks decreased last year only to be replaced by smaller scale, stealthier attacks targeted at specific organisations or individuals, and designed to extract sensitive information. Financial gain has become the number one motive for hackers, according to IBM's latest Global Business Security Index.

Email-borne viruses went into decline last year. One in every 36.15 emails (2.8 percent) contained a virus or Trojan compared to 6.1 per cent, or one in every 16.39 emails in 2004. But this drop was accompanied by the increased integration of more sophisticated bot capabilities into existing malware. For example the Mytob worm, based on the earlier MyDoom worm, featured capabilities that allowed hackers to remotely control compromised (zombie) machines.
