New Ethereum feature backfires – $150K stolen in sweeper attacks post-Pectra upgrade
Ethereum’s Pectra improve launched EIP-7702, enabling wallets to quickly perform as good contracts for a greater consumer expertise.
Proposed by Vitalik Buterin, this characteristic helps account abstraction, permitting customers to batch transactions, sponsor fuel charges, and implement stricter spending controls.
Whereas this innovation improves pockets usability and safety, it has additionally turn into a possible goal for exploitation.

Wintermute’s analysis reveals that over 80% of EIP-7702 delegations are being utilized by a single malicious contract, dubbed “CrimeEnjoyor.” The contract’s code is brief, copy-pasted, and alarmingly efficient.
As soon as it good points entry to a compromised pockets – usually via phishing – it immediately drains the funds to an attacker’s deal with.
It’s automation at scale, and it’s proving expensive.

Blockchain safety agency Rip-off Sniffer highlighted one such incident the place a sufferer misplaced almost $150,000 in a single batched transaction linked to the infamous Inferno Drainer service.
With hundreds of comparable transactions already recorded, it might be that options meant to simplify Ethereum are additionally accelerating its vulnerabilities.
Possibly it’s not the code
The core subject behind the current wave of wallet-draining assaults isn’t EIP-7702. It’s the continued downside of leaked or stolen personal keys.
The brand new characteristic merely makes it sooner and cheaper for attackers to take advantage of already-compromised wallets. Safety corporations like SlowMist are urging pockets suppliers to enhance visibility into contract interactions and strengthen consumer protections.

As Ethereum evolves, the precedence should shift towards smarter pockets design, clearer signing prompts, and higher consumer training.
As a result of even essentially the most promising options can backfire when primary safety fails.
