Hardware wallet manufacturer Ledger recently discovered a malicious version of its Connect Kit, which has prompted a warning to users against connecting to decentralized applications (dapps). With this article, we will go into the details of the incident, highlighting the potential risks and providing insights from industry experts. Let’s get into it!
Malicious Version Identified
Ledger has identified and removed a malicious version of its Connect Kit, a library that facilitates the interaction between Ledger hardware wallets and dapps. Users are advised not to engage with any dapps until the situation is resolved. Ledger assures users that its devices and Ledger Live app remain uncompromised, and they will provide updates as the situation evolves.
Impact on Dapps
Developers on Twitter initially reported the compromised version of the Connect Kit. Web3 security firm BlockAid confirmed that dapps using versions 1.1.4 and above of Ledger’s Connect Kit, including Sushi.com and Hey.xyz, were affected. The attacker injected a wallet-draining payload into the compromised library, posing a significant risk to users’ funds.
Criticism and Recommendations
SushiSwap CTO Matthew Lilley criticized Ledger for the security breach, emphasizing the need for dapp teams to confirm mitigation measures before resuming usage. Ethereum core developer liaison Hudson Jameson highlighted the risks of using dapps without understanding the backend libraries they rely on. Even after Ledger addresses the issue, dapp projects using the compromised library must update their systems for safe usage.
Previous Security Concerns
Ledger has faced criticism regarding its security practices in recent times. The voluntary ID-based Recover service, unrelated to the current attack, received backlash from users who considered it a potential “backdoor.” The company’s co-founder acknowledged the service’s poor rollout but defended its technical integrity. Additionally, Ledger previously experienced incidents involving a fraudulent app on the Microsoft App Store and a customer email database breach.

Yet, in this cyber-age drama, Ledger’s technology and security teams emerge as the unsung heroes, responding to the breach within a remarkable 40 minutes. The malevolent file may have lingered for five hours, but the window of vulnerability, where funds faced potential drainage, appears to have been mercifully brief – less than two hours.
Collaboration becomes a central theme in this narrative as Ledger coordinates with WalletConnect, swiftly disabling the rogue project. The genuine Ledger Connect Kit version 1.1.8 is subsequently deployed, standing as a testament to the resilience of security measures.
Behind the code curtain, developers find themselves in read-only mode for safety reasons, while secrets are rotated on Ledger’s GitHub, fortifying the defenses against potential future incursions. A call is issued to developers to ensure they are utilizing the latest version, 1.1.8.
As the pursuit of justice unfolds, a complaint is filed, and law enforcement joins the investigation to apprehend the malevolent actor. Simultaneously, Ledger, along with partners such as WalletConnect, reports the bad actor’s wallet address, with Tether freezing the associated USDT.
