The SANS Internet Storm Center over the weekend counted some 1,070,000 URLs injected with the so-called lilupophilupop.com malware. That's up from 80 pages it had found in early December, according to SANS ISC handler Mark Hofman.
The attackers compromise sites via SQL injection, and it appears to have hit sites worldwide, with the most infections in The Netherlands "NL" domain, with 123,000, and includes some .com and .org sites, as well.
"At the moment it looks like it is partially automated and partially manual. The manual component and the number of sites infected suggests a reasonable size work force or a long preparation period," Hofman said in his blog post on the attack.
But the 1 million URL number might be inflated, said Mary Landesmann, senior security researcher for ScanSafe, which is part of Cisco. That count could include pages also discussing the attacks, she said. "As a result, there is always a huge 'increase' after an initial public report is made. In other words, counting the number of results from a search engine isn’t a good or viable means of measuring the breadth of a compromise," Landesmann said.
