There will be winners and losers in the race to become the best bitcoin extortionist emailer. The latest bitcoin scam email campaign looks like it will be one of the losers.
Starting this morning, from U.S. sources, BitcoinWhosWho.com began receiving reports of a fake bomb threat demanding $20k in bitcoin or a “mercenary” would blow up their building. So far no one has paid any of the 15 bitcoin addresses that have been identified. But, it would only take a few people falling for this to make it worthwhile for the scammer.
The email typically states the bomb or explosive device is made of “lead azide”, “Tetryl” or “Hexogen” but also “tronitrotoluene” has been reported.
Notably, the author really wants to be clear that everything is proceeding “according to my guide”. Oh, and BTW, the bomb will go off by the end of the day if you don’t pay.
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:
The total amount of bitcoin in circulation decreased by almost 9 in 2017 due to “burn” addresses. Burn addresses, like the Genesis Block, are deadlier than “zombie” addresses, because there is no chance of coming back once BTC is sent to it. There are almost 400 known bitcoin burn addresses, i.e. valid addresses with no private key, to which, for a variety of reasons, people have sent 2,759.42507135 over the years. In 2017, 9 of these addresses received 8.97140133 BTC. That is way down from 2016 when 26.04 BTC was burned. Continue reading 8.97 Bitcoins Burned In 2017→
BitcoinWhosWho.com started receiving reports of a mass email attempting to blackmail recipients out of bitcoin about a month ago. The hilariously worded text always closes with “sorry for misprints, I am foreign”. Rudimentary block exploring shows at least some of these scam addresses are being consolidated on the Russian wallet service Matbea.com. Continue reading Blackmail Scam Run on Russian Wallet Matbea→
UPDATE: WannaCry Ransomware Attack up to 14.08007493 BTC on 92 payments as of 11:30am ET May 13. Balances more than doubled in 12 hours.
Today’s widely reported WannaCry ransomware attack is extensive, growing and has already yielded ~USD$12k in profits according to a quick analysis of the BTC addresses involved. On May 12 the 3 bitcoin addresses known to be receiving extortion payments show receipt of 6.49372428 BTC in 39 separate transactions with ransom varying between .15 to .30 BTC each. None of the balances have been moved to new bitcoin addresses since receipt.
