Also on Thursday, Specter Analyst, another blockchain intelligence platform, said Thursday that “it appears there may be a phishing attack targeting Polymarket users, with estimated losses of $2.94 million so far.”
One of the hack victims, Ash, wrote on X that his wallet had been hacked and he had no idea why at the time. Ash also shared his and the attacker’s wallet address.
Polymarket has suffered other security breaches recently. In March, blockchain researcher ZachXBT highlighted a suspected security breach. He said that more than $520,000 was reportedly drained from two smart contracts on the Polygon blockchain. Polymarket later 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 unnamed third-party login provider for those account breaches.
News of the phishing attack follows reports that Polymarket is under federal investigation following a Wall Street Journal article about the platform’s misleading social media promotion of prediction markets by users bragging about profits.
