Facecrooks security shares this improved security approach
QUOTE: Lately, we have noticed an alarming trend in how Facebook scams are being spread among users. Scammers will exploit every method and medium to disseminate their malware and mayhem. We have seen like-jacking, click-jacking & tag-jacking attacks, rogue applications, the abuse of Facebook messages and chat, browser exploits…you name it. The last couple of scams we have profiled use rogue browser extensions (sometimes called addons or plug-ins) to propagate on Facebook. This typically occurs by the scammer tricking users into downloading and installing what appears to be a theme, application or required plugin to watch an advertised video.
