Facebook and Google Docs continue to be used by scammers as a delivery channel for malware and adware.
In October 2016, Facebook users were sent the links to supposedly adult videos  that can be played from a fake Youtube portal only when a target downloads and install the malicious Video Plugin.
In August 2017, the same attack vector is used to spread adware .
And today, I saw the following message on my Facebook arrived from the hacked mobile Facebook app of one of my students in past. In addition to the message, I and other victim’s friends were marked in the comment to the post with a fake video.
