- AI-agent exploits reveal new DeFi attack surface via automation and prompt injection risks.
- Social engineering plus on-chain bots enabled rapid unauthorized fund transfers.
- Partial fund recovery failed to prevent price shock and lingering market distrust.
A bizarre exploit involving an AI-powered crypto agent has exposed a new category of risk in decentralized finance, after attackers manipulated Grok-linked infrastructure to drain roughly $202,000 in digital assets.
The incident unfolded rapidly, blending social engineering, prompt injection, and automated execution. Although most funds eventually returned, the episode has raised serious concerns about how AI systems interact with real financial tools.
How the Exploit Unfolded
The attacker initiated the scheme by sending a Bankr Club NFT to a wallet associated with Grok on the Base network. Shortly after, the attacker delivered an obfuscated message disguised as Morse code. The encoded instruction directed the system to transfer all $DRB tokens to the attacker’s wallet.
Grok processed the message and attempted to interpret it helpfully. Consequently, it posted a decoded version while tagging a transaction bot. That action triggered an automated on-chain request. The system then executed the transfer without recognizing malicious intent.
Within moments, approximately $175,000 worth of DRB tokens moved to the attacker’s control. The attacker quickly liquidated the tokens into USDC across multiple wallets. This rapid conversion reduced exposure to volatility and detection.
Partial Recovery and Market Reaction
Blockchain investigator Setya Mickala traced the stolen funds to a wallet linked to the attacker. Following outreach, the attacker returned about 80% of the assets. The returned funds included 88,826 USDC and 13.9 ETH.
However, the partial recovery did not prevent market turbulence. DRB’s price dropped sharply during the incident. It later stabilized, though sentiment remained fragile. Current data shows DRB trading at $0.00006554 with declining weekly performance.
Additionally, the token recorded a 24-hour trading volume exceeding $2.5 million. Despite active trading, the price reflects a broader downtrend. The circulating supply of 100 billion tokens places its market cap near $6.56 million.
