Ukrainian "poison ad" hacker group exposed after stealing $50 mln in cryptocurrency - media
A Ukrainian hacker group dubbed Coinhoarder has been exposed by Cisco’s Talos cybersecurity team after stealing more than $50 million in cryptocurrency from users of Blockchain.info, one of the most popular providers of digital currency wallets.
The report reveals how thieves mastered a “very simple” technique through buying Google ads on popular search keywords related to cryptocurrency “to poison user search results” and snatch the contents of crypto wallets, according to Express.co.uk.
In short, if you ever searched for terms like “blockchain” or “bitcoin wallet,” you would see links to malicious websites masquerading as legitimate domains for Blockchain.info wallets.
