The friend said he had nothing to hide and suspects this is part of a random but well-crafted campaign to prey on men who may have a guilty conscience. The letter addressed the recipient by his first name and hometown throughout, and claimed to have evidence of the supposed dalliances.

It is just your bad luck that I stumbled across your misadventures while working on a job around Bellevue. Frankly, I am ready to forget all about you and let you get on with your life. And I am going to give you two options that will accomplish that very thing. That bitcoin address does not appear to have received any payments. Attached to the two-sided extortion note is a primer on different ways to quickly and easily obtain bitcoin. The clock is ticking, [name omitted].

However, as the extortionist rightly notes in his letter, the likelihood that authorities would ever be able to catch him is probably low. The last time I heard of or saw this type of targeted extortion by mail was in the wake of the breach at online cheating site AshleyMadison. But those attempts made more sense to me since obviously many AshleyMadison users quite clearly did have an affair to hide.

Whether that person follows through and pays the extortion, though, is another matter. I searched online for snippets of text from the extortion letter and found just one other mention of what appears to be the same letter: It was targeting people in Wellesley, Mass, according to a local news report from December The envelopes have no return address and are postmarked out of state, but from different states.

This Bitcoin version seems to have improved its premise and modernized its payment method, but otherwise it sounds like the same old rubbish. I received a very similar PDF blackmail letter via email. It included a copy of all conversation between us from their fake profile on Ashley Madison and that continued via email. They were very good. Also, a sealed physical copy of the threat was left in the parking lot where I work with my name on it. With some digging, I may have figured out who they are.

One is Chinese, lives in the Austin Texas area. Another is a network security researcher in Maryland and is part of a hacker group. And they access the internet anonymous using a TOR. The real question is…. I have emails and physical evidence they left at my workplace. I am a producer with CBS News. Can you email me at rosenblume cbsnews. I adjusted malisious soft on a porn web-site which was visited by you.

When the object press on a play button, device begins recording the screen and all cameras on ur device begins working. Moreover, my program makes a remote desktop supplied with key logger function from ur device , so I was able to collect all contacts from ya e-mail, messengers and other social networks.

NBC recently aired a special examining it and how Kaspersky labs may have been implicated in the computer attacks.

The evidence is strong enough that the Pentagon has removed it from all of their machines and Congress has a bill pending that would make it a crime to install their software on any U.
