Spammers hijacking legit newsletters
Hackers have begun using newsletters to launch spam, joining legitimate newsletter creators in the hope to defy spam filters.
Researchers at Symantec say they've uncovered email messages that appear to be genuine newsletters - only to find the emails have been hijacked by spammers.
According to the US based anti-virus firm, Spammers embed their messages within a single file, which pops up after an affected user reads what he or she thinks is a normal newsletter message for a few minutes.
Doug Bowers, senior director of anti-abuse engineering for Symantec, told SCMagazine.com today that the new spammer strategy is ironic, considering the problems legit newsletters once had avoiding spam filters.
