What a shit show this is? A person who claims he used a loophole in a site to steal money from other users... and users who ask the thief to return the money.
@FelErYun Show us a screencast of this exploit. Otherwise I say fake. And the reports you sent, why not publish them here (without the details) or on forum thread. FBC will quickly see it.
I think they are all fake... Except for a bunch of words, I didn't see any screenshots, transactions, or any kind of evidence that would back up their stories. There's a scam accusation section, if some members think they have been cheated/scammed in any way they can open a topic there and attach all the evidence they have. Without proof, no one will believe these claims.
In sum up there were two attack attempts; first was the injection of fake notification that fbc deposit address have changed and second one with defaced website containing message about locked account and attempt to get ransom from unlocking it.
If you really interested in this case just try to read my posts and my conversation with other users.
I registered account here mainly to show the issue I faced.
Luckily I avoided of being scammed and I think I described quite well my side of the story.
In my posts you can find a lot of screenshots including defaced website, emails from scammers, proof of injected malicious script etc.
Some posts above you can even find a source code of the script used to attack some other user.
I didn't deposit any funds to scammers, but other users actually posted massages with all information you mentioned (TX hash, deposit addresses, User IDs) - but this is in another topic about fbc -
