Distributed database that is used to maintain a continuously growing list of records, called blocks
New details about "well-known" exchange. The BTC-e is responsible for cashing 95% of the proceeds of the bitcoin-extortioners since 2014. This is stated in the report, which was presented at the conference on computer security Black Hat USA 2017, and reported by the BleepingComputer.
The study involved Google, Chainalysis, as well as specialists from universities in California, San Diego and New York.
During the project called "Tracking Ransomware End to End" 34 families of viruses were analyzed. From a huge set of executable files, the research project was able to create an overall picture illustrating the amount of payments related to the extortion programs carried out over the past three and a half years.
Revenue per monthly
Researchers note that 2016 was the most profitable year for ransomware, during which the monthly volume of pay-off payments reached $ 2 million or more. The largest increase in the incomes of extortionists also coincides with the periods of distribution of the programs of the Locky family and Cerber. So, crypto-hijacker Locky collected about $ 7.8 million, while Cerber - $ 6.9 million, and Cryptolocker - $ 2 million.
Is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen
Researchers agreed that the end point of 95% of all payments was the BTC-e exchange. Criminals used it to convert Bitcoins into fiat money.
The alleged co-owner of BTC-e Alexander Vinnik was detained in Greece recently.
Worth reminding that Financial Crimes Enforcement Network has imposed a $ 110 million penalty on the BTC-e crypto exchange for "deliberately violating US anti-money laundering laws (AML)." In addition, Alexander Vinnik is named the main suspect in the case of MtGox.
