Kraken has reported that a security researcher exploited a bug, resulting in the unauthorized withdrawal of $3 million worth of digital assets from the exchange's treasury. Despite the significant loss, Kraken has assured that no user funds were endangered.

An anonymous security researcher discovered a critical bug and alerted Kraken on June 9. However, the researcher exploited the bug, withdrawing over $3 million using two accounts associated with them. Nick Percoco, Kraken’s chief security officer, disclosed this incident in a June 19 X post, revealing that the researcher is demanding a reward for the stolen funds. Percoco described the researcher’s actions as extortion, stating, "Instead, they demanded a call with their business development team (i.e., their sales reps) and have not agreed to return any funds until we provide a speculated $ amount that this bug could have caused if they had not disclosed it. This is not white-hat hacking, it is extortion!"

Kraken emphasized that ethical hacking does not involve stealing funds. The researcher initially demonstrated the bug with a $4 crypto transfer, which would have sufficed to prove the flaw and earn a reward from Kraken’s bug bounty program. However, the researcher shared the bug with two other accounts, which siphoned nearly $3 million from Kraken. Percoco criticized the researcher’s behavior, noting that it diverges from ethical hacking principles. He stated, "In the essence of transparency, we are disclosing this bug to the industry today. We are being accused of being unreasonable and unprofessional for requesting that 'white-hat hackers' return what they stole from us. Unbelievable."

The Kraken incident highlights a broader trend of increasing crypto exploits. In the first quarter of 2024, hackers stole digital assets worth $542.7 million, a 42% increase compared to the same period in 2023. Notably, private key leaks were the leading cause of these exploits, overshadowing smart contract vulnerabilities, which saw a significant decrease in associated losses. According to Merkle Science’s "2024 Crypto HackHub Report," funds lost to smart contract vulnerabilities fell by 92% to $179 million in 2023, down from $2.6 billion in 2022. The cryptocurrency industry has faced 785 reported hacks and exploits, resulting in nearly $19 billion lost over the past 13 years, with over 55% of hacked digital assets lost to private key leaks during 2023.

Kraken’s case underscores the fine line between ethical hacking and extortion in the crypto industry. While bug bounties are designed to incentivize the discovery and responsible disclosure of vulnerabilities, exploiting bugs for personal gain and demanding rewards can undermine trust and security efforts. The rising trend of crypto exploits in 2024 highlights the ongoing need for robust security measures and ethical practices in the cryptocurrency space.
