Computer worms will cost European ISPs an estimated €123m this year, according to a study to traffic management firm Sandvine out today. Sandvine said its study shows attacks on European service providers are now a daily occurrence.
Although worms are usually associated with attacks on corporate networks, the malicious traffic also ties up service provider networks, degrading the broadband experience for home Internet users. Meanwhile, outbreaks of computer worms generate a huge upsurge in support calls to ISPs. On any given day, between five and 12 per cent of all Internet traffic moving across European ISP networks is malicious, according to Sandvine.
