This is a recent tech related issue that happened to someone I know. A scam unfortunately and the hacker took advantage of a very fragile situation too. Its amazing at what lengths hackers will go to take advantage of a person during their plight.
A friend of mine lost their dog so they made a post on Facebook about that and if anyone could help them find their missing dog. They put their email and phone number out there in that post. Their post was shared numerous times. A few weeks went by and someone contacted them saying they found their dog. My friend was very excited to hear the news and asked how they can get in touch. The person said they need to verify my friend really owns the dog and asked them for the security code that was just sent to their phone. Not thinking of anything other than having a chance to see their loyal friend again, they provided the security code that was sent to their phone to this stranger.
Boom. Their email was hacked.
Guard your phone number and email folks. Facebook is a new way to spread the word and get some traction for things we need urgency on, but displaying private information publicly, even in dire situations, can bite you in the butt. Even if a person who is friends with you on Facebook prods for private information you have to guard yourself and consider if they've even been hacked and someone is posing as them.
It happens and it sucks. Many of us here probably wouldn't fall for something like this, but we're all human. We can also pass things like this on to our friends who are not in the technical world like us. If you see something like this happen simply just direct message that person and recommend they remove their private information and just request anyone to contact them via private message, not on a public or 'private' facebook post.
