Hackers 'recycling code' to spread worms
Despite worms such as Sasser, Bobax and Wallon wreaking havoc throughout May, security vendor Trend Micro says it detected fewer examples of new malicious coding last month than it did in April.
Trend Micro said it identified around 1,050 new computer worms, viruses, Trojans and other examples of malware in May, compared to 1,700 the month before. However, the company said despite the decrease, "actual virus activity remained high".
IDC analyst Megan Dahlgren says the results show that hackers are recycling the old codes.
"They are exploiting already existing malicious code and reintroducing it into a new environment," she said.
