“I think you are in this video” or similar Videos with no explanation “please share” “Attachment Unavailable”
Do not click and do not share!
When you click on the links on your messages, they will often propagate and send the same link to a lot or all your Messenger contacts.
You didn’t necessarily get “hacked” but Messenger just automatically forwarded the same link as you clicked on. This doesn’t mean they have your log in information (unless you gave your login after you clicked the link) – it just means an annoying or malicious link is just making the rounds through Messenger. The headline is compelling to make you want to click on it. Messenger "hack" doesn't mean you were compromised but play it safe and assume you were hacked. Don’t just click on message links. Think first.
Any time something gets odd on any social media - change your password in case you are compromised. There's also chance you accepted a code that got into your system - so pay attention to any new issues on your computer. You never know how hackers get in and take advantage.
When I get one of these, I delete it from the conversation without clicking on them. I message the person who sent it to let them know and ask if they intended to send it. Every time they didn’t willfully send the message.
Don’t panic but do inform your friends on FaceBook that you didn’t intentionally send the message – but above all DO NOT CLICK ON IT! PR
