Bybit Breach and CEX Vulnerabilities Trigger $2.17B Losses as Lazarus Group Exploits Systemic Weaknesses in 2025
1min read
Aime SummaryThe cryptocurrency sector experienced a significant security crisis in mid-2025, marked by the Bybit breach and a surge in centralized exchange (CEX) vulnerabilities. According to the Mid-Year 2025 Crypto Crime Report, 75% of annual crypto losses—$2.17 billion—stemmed from the Bybit hack and 10 other CEX breaches. The Bybit incident alone accounted for 70% of these losses, with attackers stealing $1.5 billion worth of
tokens through social engineering and compromised signature machines. North Korea-linked Lazarus Group exploited insider access and phishing tactics to execute the theft, laundering funds via cross-chain bridges and privacy tools [1].The attacks highlighted systemic weaknesses in CEX infrastructure, as platforms with high liquidity became prime targets for sophisticated cybercriminals. The report noted that breaches at SmartEx, Nobitex, and BitoPro further underscored vulnerabilities in centralized systems, challenging the perception that decentralized finance (DeFi) is the primary security risk [1]. Human error and social engineering were identified as critical factors, with phishing attacks alone causing $420 million in losses across 130 incidents.
The trend intensified in July 2025 when Indian exchange CoinDCX reported a $44 million breach linked to Lazarus Group. Attackers exploited misconfigured credentials and liquidity provision accounts to siphon assets without triggering alarms, mirroring methods used in the Bybit incident [9]. CoinDCX responded by launching a $11 million bounty program to recover funds, though the breach reinforced concerns about centralized control. Analysts pointed to backend access vulnerabilities—such as exposed API keys—as a recurring exploit, enabling attackers to move assets across chains undetected [9].
The stablecoin market, which surged 23.5% to $252 billion in H1 2025, faced destabilizing risks. CertiK attributed half of the sector’s losses to the Bybit breach, which eroded confidence in liquidity systems [7]. Meanwhile, FDUSD temporarily depegged to $0.76, illustrating how CEX vulnerabilities could ripple through broader financial structures. Bybit CEO Ben Zhou announced measures to enhance liquidity safeguards following the breach, but critics argue centralized systems remain fundamentally fragile [10].
The incidents prompted calls for stronger security frameworks, including multi-layered access controls and real-time monitoring. CoinDCX’s bounty initiative reflects a growing emphasis on transparency and recovery, though it does not address systemic infrastructure flaws. With CEX losses surpassing $2 billion in 2025, the sector’s resilience will hinge on adapting to increasingly sophisticated threats. Investors are urged to diversify assets and scrutinize exchange practices amid persistent risks.
