According to TechFlow, Kraken Chief Strategy Officer Nick Percoco said that the trading platform regards the recent loss of nearly $3 million as a "criminal case" and is coordinating with law enforcement agencies to recover the funds.

Percoco claims the unnamed researchers stole millions of dollars in cryptocurrency from Kraken by withdrawing funds that had been deposited into their accounts before the deposits were completed. The attackers were effectively printing assets, he wrote.

Earlier news, blockchain security agency CertiK announced on a social platform that a series of serious vulnerabilities had been discovered in the Kraken exchange, which could result in potential losses of hundreds of millions of dollars.
