Commtouch Security Number Of The Month May 2013: 50% Financial Loss For Victims Of Pump And Dump Spam

Spam attempts to lure email recipients into buying cheap stock with a low trading volume
MCLEAN, Virginia, May 22, 2013 /PRNewswire/ --

In March 2013, pump and dump spam struck back with a force not seen since 2008.

It attempts to lure email recipients into buying cheap stock with a low trading volume which the spammers previously bought at a low price. Once enough users have bought shares and the stock price has risen, the spammers sell - resulting in gains for them and losses for other buyers. In the case of a typical pump and dump campaign launched on April 19, the spammers bought the shares for as low as

$0.22 and then sold them for as high as $0.40, causing the stock to plummet to $0.20. In this way, the spammers gained more than 80% while the victims lost up to 50% (estimates based on analyses of the stock during the campaign).
