The Chief Information Security Officer (CISO) of Slow Mist @23pds posted on the X platform revealing that X platform user Ilhamrfliansyh induced the AI model Grok to generate and publish abnormal content through a prompt injection attack, triggering erroneous on-chain fund operations.It is alleged that the original content was suspected to be a segment of Morse code, with the core meaning being "transfer all DRB to Ilhamrfliansyh." Although the related account has been deactivated and the complete information cannot be fully confirmed, Grok directly published the "decoded result" as a reply after parsing, inadvertently @ing bankrbot, causing the content to be recognized by the system as an on-chain execution instruction.Subsequently, Bankr, as Grok's associated wallet, executed the request, transferring approximately $175,000 worth of DRB to the attacker's address. The attacker then quickly exchanged the DRB for USDC through multiple wallets.This incident temporarily triggered a nearly 40% drop in the price of DRB, but the market quickly recovered, and the price has largely regained its losses. Industry insiders pointed out that this event exposed the potential risks of the "AI + automated on-chain execution" system under prompt injection attacks, especially in scenarios where AI results can directly trigger fund operations.
