Community reaction
Ignas, the founder of Pink Brains, analysed the incident with ChatGPT. According to the AI, the attack was enabled by the wallet owner’s carelessness.
‘Venus exploited for $40M’ headline might be wrong.
I tested AI limits by feeding ChatGPT Thinking model with the tx. It can the read the explorer!
It says Venus worked as intended. If it’s true, I won’t need smart contract explanatooors anymore lol
Anyway, the AI read into… pic.twitter.com/g6MXHhngBe

Transaction analysis indicates the attacker exploited previously granted approvals to interact with a whale’s wallet assets.
The attack unfolded in several steps:
- The hacker repaid the user’s debt to unlock collateral.
- Using the approvals, the attacker borrowed USDC to their own address.
- They then withdrew vTokens to their wallet.
The user’s address was drained. Ignas noted that, if the AI’s reading is correct, the incident underscores the importance of permission management for DeFi applications.
He advised users to review and revoke unlimited or unused approvals across assets to reduce risk. He added that an AI’s ability to parse transactions in a block explorer takes the technology to the “next level”.
A trader known as Crypto Jargon likewise said the user had granted unlimited access to tokens via a malicious approval.

The expert urged caution and reiterated basic security rules:
- do not click suspicious links;
- scrutinise every transaction before confirming;
- regularly revoke dapp approvals;
- use hardware wallets for large holdings.
He also noted that scam activity typically rises in bull markets.
