A security firm, Certik, identified a vulnerability in Kraken's crypto exchange and withdrew $3 million to test its severity. Kraken considered this theft and accused Certik of extortion.

Certik claimed it was a white-hat test and returned the funds, but some were sent through a mixing service raising concerns about their motives.

This incident highlights the murky line between ethical hacking and exploitation, potentially damaging trust in the crypto security industry.
