Bitcoin Blackmail Letter Scam Raising Prices

Blackmail letter
Not all bitcoin sextortion attempts are occurring over email right now.

Krebs on Security blogged about this scam in January. Back then the amount demanded was around $2,500. In May typical reports had risen to around $8,500. Today the letters are demanding as much as $15,500. Continue reading Bitcoin Blackmail Letter Scam Raising Prices

I Know Your Password #Bitcoin Extortion Email Variant

A new twist on an old trick emerged this week. The porn ransom email claiming to have incriminating video of the recipient which will be released to contacts if not paid in bitcoin, has now included an old compromised password of the recipients in an attempt to add credibility to the scam. Gotta appreciate that dark web creativity. Where did they get all those passwords? The first report of this new variant was received July 10. Since then dozens more reports have come in relating to just over 2 dozen bitcoin addresses as of Friday. This address has been reported 9 times and also has the most total received at 2.83 BTC:

Bitcoin Porn Blackmail Scam Moved to Poloniex Wallet

When reports of this email scam first started appearing last September the perpetrators were discovered to be using a Matbea wallet. That appears to have changed. On May 30 every output transaction from hundreds of reported blackmail scam addresses went to a Poloniex wallet address.

These bitcoin addresses were reported as scams related to the porn blackmail email:

Each of them shows an output to 1E2J2DAFGToqmTxK5H8fG6V3Tp3xqSiAm4 on May 30, 2018.

A quick investigation shows 1E2J2DAFGToqmTxK5H8fG6V3Tp3xqSiAm4 is among the Poloniex wallet cluster.
