Abracadabra DeFi Hack: $13M Stolen in GMX Token Exploit

In a significant security breach that highlights the ongoing challenges in DeFi security, Abracadabra.Finance has suffered a $13 million exploit targeting its GMX-linked lending pools. The attack, which occurred on March 25, 2025, specifically targeted the platform’s “cauldrons” – specialized lending markets where users can borrow against cryptocurrency collateral.

Key Details of the Abracadabra Exploit

• Total funds stolen: 6,260 ETH (approximately $12.98 million)
• Target: Cauldrons using GM tokens (GMX liquidity tokens) as collateral
• Affected platform: Abracadabra.Finance’s lending pools
• User funds status: No user collateral affected

Technical Analysis of the Attack

Blockchain security firm PeckShield first identified the breach, which specifically targeted contracts involving GMX and Abracadabra. The exploit’s sophistication is particularly noteworthy given that the affected cauldrons had undergone full security audits by Guardian Audits, the same firm that audited GMX’s contracts.

GMX’s Response and Impact

GMX has officially distanced itself from the incident, confirming that their core infrastructure remains uncompromised. The team emphasized that the breach was exclusively related to Abracadabra’s implementation of GM tokens as collateral in their cauldrons.

Abracadabra’s Immediate Response

The protocol has taken several immediate steps to address the situation:

• Launched a comprehensive investigation with core contributors and engineers
• Offered the attacker a 20% bug bounty
• Opened communication channels via email and on-chain messaging
• Partnered with Guardian and GMX for damage assessment

Historical Context and Pattern Recognition

This isn’t Abracadabra’s first security incident. Last year, the platform experienced a $6.49 million exploit that affected its Magic Internet Money (MIM) stablecoin’s dollar peg. This pattern of recurring exploits raises important questions about DeFi security practices and audit effectiveness.
