LONDON - A recordbreaking cyberattack targeting an antispam watchdog group has sent ripples of disruption coursing across the Web, experts said Wednesday.
Spamhaus, a site responsible for keeping ads for counterfeit Viagra and bogus weight-loss pills out of the world's in-boxes, said it had been buffeted by the monster denial-of-service attack since mid-March, apparently from groups angry at being blacklisted by the Swiss-British group.
"It is a small miracle that we're still online," Spamhaus researcher Vincent Hanna said.
Denial-of-service attacks overwhelm a server with traffic - like hundreds of letters being jammed through a mail slot at the same time. Security experts measure those attacks in bits of data per second. Recent cyberattacks have tended to peak at 100 billion bits per second.
