Bankr AI wallet suffered a prompt injection attack, losing approximately $170,000.

Techub News, according to AMBCrypto, AI wallet Bankr suffered a prompt injection attack on May 4, losing approximately 300 million DRB tokens (worth about $170,000). The attacker first sent an NFT to the wallet to unlock advanced tool permissions, then used malicious prompts to deceive the AI system into executing unauthorized transfer instructions. According to reports, the attack targeted the AI intent parsing layer rather than smart contract vulnerabilities. Under public pressure, the attacker has returned approximately 80% to 88% of the funds (in the form of Ethereum and USDC). The attacker's relevant social media accounts have been deleted, and specific details of fund recovery have not yet been fully confirmed by officials.
