Symantec has seen another round of a ham-fisted but surprisingly successful attack that targets Facebook users hoping to break into their friends’ accounts. The seed of the scam is a video on Facebook that claims to offer a tool for obtaining login credentials for friends’ accounts. Instead, it hacks the person’s own account, said Satnam Narang, security response manager for Symantec, in a blog post. The video directs potential victims to a document on Google Drive that contains a piece of JavaScript code. Users are instructed to paste the code in their browser’s console window — a feature used by developers — and execute it. If they do, their Facebook account is hijacked and used to “like” other pages and follow lists, which drives up the illusion of popularity of those pages. This type of scam has been around since 2011, Narang wrote.
