A recent security issue in the Ledger Connect Kit library has put users of Ledger, a prominent hardware wallet company in the cryptocurrency industry, at risk. The malicious version of the software allowed attackers to redirect users’ funds to their own wallet through a modified interface. This means that users could unknowingly send their cryptocurrency directly to the hacker. Ledger has taken immediate action to address the situation. They have replaced the compromised version of the library with a secure one within 40 minutes of discovering the attack. However, the vulnerability was active for approximately 5 hours. As a precaution, Ledger advises users not to use the Ledger Connect Kit for at least 24 hours and to always check for the latest version (currently 1.1.8). To ensure they have the correct version, users should visit the link provided by Mudit Gupta and verify that the version is 1.1.8. If it is not, they should clear their browser cache. For Chrome users, Gupta provides step-by-step instructions on how to clear the cache using Chrome Developer Tools. Gupta also advises users to temporarily avoid interacting with any decentralized applications (dApps) until they have the fixed version of the library. Some applications may be integrating and directly serving the malicious library. For dApp developers, Gupta recommends re-deploying or regenerating their packages and notifying the community when it is safe to use their applications. Users who have used any dApp in the last ~6 hours are advised to check if they still have all their funds. If they do, they are considered safe. Fortunately, JavaScript is loaded live by default and is not included in packages, so if users have the latest version of the library, they should be safe in 99.99% of dApps. This incident highlights the importance of cybersecurity in the cryptocurrency ecosystem. Ledger’s swift response and collaboration with the crypto community demonstrate the sector’s commitment to security. While the scare was significant, it sets an example for addressing cyber challenges in the crypto world.
