On Thursday as well, Specter Analyst, another blockchain intelligence platform, said on Thursday that “It appears there may be a phishing attack targeting Polymarket users, with estimated losses of $2.94M so far.”
One of the victims of the hack, Ash, on X wrote that his wallet had been hacked and had no idea why at the time. Ash also shared his and the attacker’s wallet addresses.
Polymarket has suffered other security breaches recently. In March, blockchain investigator ZachXBT highlighted a suspected security breach. He said over $520,000 was reportedly drained from two smart contracts on the Polygon blockchain. Polymarket then said the funds were safe.
In December, the platform confirmed a security incident on its Discord channel after users reported missing funds and suspicious login attempts. It blamed an unidentified third-party login provider for those account breaches.
The news of the phishing attack follows reports that Polymarket is under federal investigation following a Wall Street Journal article into the prediction markets platform deceptive social media promotion of users boasting winnings.
