DeFi Security Tool Revoke.Cash Issues Fix For New Crypto Scam

Revoke.Cash, a leading decentralized finance (DeFi) security platform, has swiftly responded to user complaints regarding a growing crypto scam involving fake approvals. In a bid to mitigate this fraudulent activity, Revoke has introduced a new feature aimed at protecting its users from falling victim to these deceptive practices. 

Scammers Exploit Gas Tokens To Deceive Users

Scammers have reportedly found a novel way to profit from unsuspecting crypto users by leveraging a scheme involving gas tokens. Over the weekend, received complaints regarding a crypto scam that lures users into revoking what they believe to be legitimate approvals, only to face unexpectedly high transaction fees. These malicious actors create counterfeit gas tokens, which they distribute alongside fake approvals. 

According to the security platform, the scam relies on the use of so-called “gas tokens” by the perpetrators. Gas tokens were initially developed as a response to the increasing Ethereum network fees, allowing users to store low-cost gas during periods of reduced network demand. This functionality enabled users to mint gas tokens at lower fees and utilize them when fees surged, thereby securing lower transaction costs.

Revoke warned about these fake approvals on a Twitter post saying:  “Yesterday, we received reports of people seeing unknown approval transactions in their transaction history. It turns out that this is a new scam where scammers use so-called gas tokens to steal money when victims revoke these “fake approvals”.

The scammers employ psychological tactics to lure users into believing that revoking these fraudulent approvals is necessary. Once users initiate the revocation, a transaction with excessively high gas fees is triggered, enabling the scammers to profit at the expense of the victims.
