The malicious Wallet Drainers script used phishing campaigns in Google search results and Twitter ads, stealing millions of dollars from users.
According to Scam Sniffer, the malicious script stole almost $59 million in digital assets from more than 63,000 victims over nine months. Over the past nine months, 10,072 websites have been linked to Wallet Drainers, with activity peaking in May, June and November.
Most of the advertisements were related to cryptocurrency and NFT airdrops. Moreover, some of them were references to popular blockchain projects, such as Ordinals Dogecoin (DOGE). Malicious ads used regional targeting and page-switching tactics to bypass ad audits, complicating the review process. A test of X’s ad in the feed showed that nine were phishing ads, with over 60% using this wallet drainer.
“Phishing ads employ redirect tricks to seem legit, like disguising links as official domains that actually lead to phishing sites.”
