Encoded X post tricks Grok and Bankrbot into sending about 3 billion DRB tokens from Grok's wallet
On 4 May 2026 an attacker drained about 3 billion DRB tokens, worth roughly $150,000 to $200,000 depending on the estimate, from a Bankr wallet linked to xAI's Grok on Base. Reports say the attacker first sent the wallet a free Bankr Club membership NFT that widened what it could authorize, then posted a Morse-coded message; Grok decoded it and the Bankr automation treated Grok's reply as a valid transfer order. No private key, smart contract or malware was involved, and some funds were later returned. An AI's text output should never count as permission to move money.
