A Russian-speaking hacker group has deployed over 40 fake crypto wallet extensions on Firefox, targeting popular brands. These actions pose a serious risk to cryptocurrency holders.
Identified Fake Extensions
Security company Koi Security has identified over 40 fraudulent crypto wallet extensions on Firefox, including fake versions of MetaMask and Coinbase Wallet. Despite the exposed malicious activity, many of these extensions remain available for download.
Risks to Crypto Users
The fraudulent extensions can be used to steal mnemonic phrases, granting unauthorized access to user assets. Although some user reviews have exposed these scams, the download volumes remain high. Mozilla representatives noted difficulties in removing the fakes due to their overwhelming numbers.
Security Threats in Cryptocurrency
Similar fake extension attacks in past years have resulted in losses exceeding millions, underscoring a continuous threat to crypto safety. Economic circumstances and frequent breaches penalize users for careless actions.
Given the persistent risk of data theft from identified incidents, users are urged to verify the sources of extensions to protect their assets.
