For years, hackers have robbed Bitcoin investors, emptying their cryptocurrency wallets without fear of being caught thanks to the relative anonymity of the blockchain. Now, Cisco (csco, +4.42%) has exposed the thieves behind a string of particularly flagrant attacks.
A Ukrainian hacker group dubbed Coinhoarder has stolen more than $50 million in cryptocurrency from users of Blockchain.info, one of the most popular providers of digital currency wallets, according to a report published Wednesday by Cisco’s Talos cybersecurity team.
The report explains how thieves preyed upon their victims using a “very simple” yet treacherous technique: Buying Google ads on popular search keywords related to cryptocurrency “to poison user search results” and snatch the contents of crypto wallets. This meant people Googling terms like “blockchain” or “bitcoin wallet,” saw links to malicious websites masquerading as legitimate domains for Blockchain.info wallets.
