219.141.184.178 attack
Typical blackmail attempt. But instead of the usual "I have a video of you where you visit sex sites", now a new variant. "You mess around with other women and I get your messages from it." And then the usual: The deal is next. You make a donation of $ 950 worth in Bit Coln value. Otherwise, well ... your secret will not be a secret anymore. I created a special archive with some materials for your wife that will be delivered if I don`t get my donation. It took me some time to accumulate enough information. Whoever falls for such shit is to blame. And by the way, if the idiot blackmailer reads this ... I'm not married at all. The blackmail comes via a chinese server again: 183.60.83.19#53(183.60.83.19)
