Facecrooks Security notes a highly realistic and rapidly spreading version of a fake Adobe flash player update that can compromise Facebook security controls:
QUOTE: Security researchers at Avast, an antivirus company, have found a link that has been spreading rapidly on Facebook and Twitter that prompts users to download malware that looks like Adobe Flash Player technology. Once users download the fake Adobe software, the scammers can take control of a user’s profile, posting to their feed, liking pages or becoming a fan.
Clickjacking scams like this one are all too common on social media, where users are more likely to trust links posted by their friends. However, avoiding these scams ultimately comes down to common sense. Before clicking on any link, and especially before downloading any software, examine the content of what you’re about to download carefully. If it doesn’t look or feel right, or if it doesn’t seem like something that your friends would post, then don’t click. While hackers exploit users’ inherent trust of their friends, looking at shared content with a more discerning eye can easily prevent you from falling prey to cons like this one.
