Hacken Security Breach Details
Hacken experienced a significant security breach affecting its native HAI token on June 21, 2025, linked to a human error in key management.
The incident highlights ongoing vulnerabilities in cross-chain bridge security and key management, impacting market confidence and prompting urgent preventative measures.
The breach involved Hacken, a known cybersecurity firm, compromising HAI tokens across Ethereum and Binance Smart Chain. Unauthorized minting caused a drastic 98% crash, with a total loss estimated at $5 million.
The exploit primarily impacted Hacken’s operations, with essential actions aimed at securing cross-chain bridges and safeguarding remaining assets. The breached systems involved Ethereum, BSC, and VeChain networks.
Hacken’s market capitalization suffered a sharp decline, triggering concerns over the reliability of cross-chain protocols. The core issue involved private key exposure, reflecting critical lapses in security protocol adherence.
Today, @hackenclub appears to have suffered a security breach across $BNB and $ETH networks. The deployer wallet of the $HAI token seems to be compromised, allowing the attacker to transfer funds. Root cause seems to be private key linked to the bridge deployment. – Cyvers Alerts
Expert assessments draw parallels with past incidents like the Ronin Bridge hack, underscoring longstanding risks in the Web3 ecosystem. Observers suggest enhanced regulatory oversight and technological improvements are essential to mitigate such vulnerabilities.
Cyvers Alerts, an analytics firm, stated the root cause was tied to a private key linked to bridge deployment. Hacken has yet to disclose a recovery strategy. Market responses remain cautious, awaiting further updates from the company.
