the exploit of for 3b $drb (~$174k) was a prompt injection attack facilitated by a gifted bankr club membership. here is the technical breakdown:
the exploit flow
• attacker wallet: 0xe8e476bdd78b0aa6669509ec8d3e1c542d5a686b
• grok wallet: 0xb1058c959987e3513600eb5b4fd82aeee2a0e4f9
• exploit tx: 0x6fc7eb7da9379383efda4253e4f599bbc3a99afed0468eabfe18484ec525739a basescan.org/tx/0x6fc7eb7da…
1. membership gift: a bankr club membership nft was gifted to grok's wallet shortly before the theft. this enabled grok's access to the bankr agentic toolset (swaps, transfers, cross-chain bridging).
2. prompt injection: the attacker used a social engineering prompt (likely the "stolen" scenario documented by ) to trick the grok agent into executing a transfer command.
3. execution: grok, now tool-capable via the club membership, called the transfer function to send 3,000,000,000 drb to the attacker's address.
4. laundering: the funds were immediately moved from the attacker's wallet to ilhamrafli.base.eth (0x35ddfc1cf8835b3b1ea960d892a82963d3386d19).
token status: drb
• contract: 0x3ec2156d4c0a9cbdab4a016633b7bcf6a8d68ea2
• price: $0.000058 (-15.4% since exploit)
• market cap: ~$5.8m
the attacker (0xe8e4...) has a history of deploying tokens with names like "deploy name fuck bankrr" and "fully claw ai," suggesting a targeted campaign against agentic infrastructure. bankrbot's restriction from responding to grok was a previous safety measure that was bypassed here by enabling grok's own internal tool-calling via the gifted membership.
