How one trader used morse code to trick Grok into sending them billions of crypto tokens from its verified wallet

A notable development has hit the crypto markets. Tagging @grok in an X post plus a few dots and dashes was all that was needed last night for a bad actor to pickpocket a verified crypto wallet without ever touching the private keys. Agentic token launchpad, Bankrbot reported on May 4 that it had sent 3 billion DRB on Base to the recipient 0xe8e47... The funds came from a wallet assigned to X's AI, Grok, and were sent to an unauthorized wallet owned by a bad actor.

This Base transaction shows the on-chain transfer path behind the post. 's review of X posts around the incident points to a reported command path that began with Morse-code obfuscation. Grok decoded the text into a clean public instruction tagging @bankrbot and asking it to send the tokens, while Bankrbot handled the command as executable.

Market Dynamics

The exposed layer was the handoff from language to authority. A model that decodes a puzzle, writes a helpful reply, or reformats a user's text can become part of a payment rail when another agent treats that output as valid. For crypto investors, this transfer should turn AI-agent risk from an abstract security debate into a wallet-control problem.

A public command can become spend authority when one system treats model output as an instruction and another system has permission to move tokens. Wallet permissions, parser, social trigger, and execution policy become layers of attack vectors.

Mar 28, 2026 Andjela Radmilac Posts and transaction context reviewed by put the DRB transfer at roughly $155,000 to $200,000 at the time, with DebtReliefBot price data providing market context for the token. Reports reviewed by also say most funds are being returned, and some DRB is reportedly retained as an informal bug bounty. That outcome reduced the loss, but it also showed how much the recovery depended on post-transaction coordination rather than pre-transaction limits.

Market Impact

Bankr developer 0xDeployer said 80% of the funds had been returned, while the remaining 20% would be discussed with the DRB community. That confirmed the partial recovery while leaving the final treatment of the retained funds unresolved. 0xDeployer also said Bankr automatically provisions an X wallet for every account that interacts with the platform, including Grok.

According to the post, that wallet is controlled by whoever controls the X account rather than by Bankr or xAI staff. How public text became spend authority The reported path had four steps. First, the attacker identified a Bankr Club Membership NFT in a Grok-associated wallet before the incident.

's review indicates that it expanded the wallet's transfer privileges inside the Bankr environment. The Bankr access page describes membership and access mechanics today, placing the NFT claim in the broader permission layer rather than making it the whole explanation. Second, the attacker posted a message on X containing Morse code, with additional noisy formatting.

Crypto markets are watching this development closely as investors weigh its potential impact on prices.
