Facebook scammers have used a false rumor about the identity of Tupac's killer to trick tens of thousands of people to install a rogue spam application and complete surveys.

The spam messages produced by this scam read: "It seems they finally solved the mystery of TUPAC's killer, Suge Knight was arrested today, watch the full video! [link]"

The message also contains a picture of Sure Knight with a caption reading "Suge Knight killed Tupac Shakur? Watch the full video, this is insane I can't believe the mystery has been solved after all this years."

Suge Knight, by his real name Marion Knight, Jr., is the founder and CEO of Death Row Records, Tupac Shakur's record label at the time of his death.

Snoop Dogg, who was also signed to the label until 1997, accused Knight of being involved in Shakur's murder on several occasions, the last time in 2006.

The theory circulated again on the Internet recently because of a hoax news videoreated by a user named Kasik.

It appears this fake video raised enough interest from the general public for scammers to adopt it in their own campaign.

The advertised link takes users to a rogue Facebook app called "They Found Tupacs Killer?!" which asks for permission to post on their walls and access their information.

If installed, this app proceeds to send spam messages from people's accounts and redirects them to a page claiming they need to complete a 30-second test before being allowed to see the shocking video.

These tests, better known as surveys, try to gather personal information from users and subscribe them to premium rate services. Scammers earn hefty commissions through affiliate marketing schemes every time that happens.

If you fell victim to this scam go to Account > Privacy Settings > Applications and Websites and revoke the permissions of the rogue app. Also delete the spam messages posted on your wall.
