Heightened Risks for Users
The compromised Ledger connector library, widely adopted by various DApps, has added a wallet drainer, introducing the possibility of unauthorized asset access. While the draining process may not occur autonomously, prompts from browser wallets, such as MetaMask, may expose users to malicious actors.
On-Chain Analysts Issue Stark Warning
On-chain analysts are urging users to steer clear of any DApps utilizing the Ledger connector, emphasizing the vulnerability of the connect-kit-loader. The severity of the breach prompts a collective call for heightened security measures and a thorough review of applications relying on Ledger’s infrastructure.
🚨We have identified and removed a malicious version of the Ledger Connect Kit. 🚨
A genuine version is being pushed to replace the malicious file now. Do not interact with any dApps for the moment. We will keep you informed as the situation evolves.
Your Ledger device and…
