"Lost Weight" Spam Campaign Spreading on Facebook and ibibo

Ulysses Wang

Websense® ThreatSeeker® Network detects that a new spam campaign is spreading on Facebook and ibibo (a popular game site in India). The content of the spam messages is: "Lost30poundsinjust4weeks all thanks to hcg. Check it out: http://spam_url".

We have seen a number of similar spam campaigns on Facebook such as, "Sexiest Video Ever" on Facebook", "Osama bin Laden scams on Facebook", etc. But, unlike previous campaigns which took advantage of a hot topic to lure visitors to click the link in the spam post, here the attackers publish a comment in the name of the account owner: "Never thought losing weight could be so easy!!!". With this method, some of the account owner's friends can be tricked into clicking the spam link:

 

For the Facebook version of the attack, the attackers abused the blogspot.com service. Here are some of the URLs used for the attack:

The spam link redirects victims to another spam site. At the moment, the spam site is unavailable, but the attackers can always update the sites with malicious content.
