Ledger, a prominent provider of hardware wallets for digital assets, has issued a stark warning to its users. The company’s “Ledger dApp Connect Kit” was recently compromised in a supply chain attack, resulting in the theft of over $484,000. The attack involved a malicious version of the Connect Kit that contained a wallet drainer embedded in the library. This compromised kit is an essential component used by decentralized apps (dApps) from various developers to integrate with the Ledger wallet service.
As a response to the breach, Ledger has urged its users to refrain from using dApps temporarily. The discovery of the malicious code highlights serious concerns regarding the security of these applications, as they can potentially enable the theft of digital assets from connected wallets.
Once the security breach was identified, Ledger’s technology and security personnel acted promptly. They removed the compromised library and promptly released a new, more secure version. Within 40 minutes of the breach being discovered, a solution had been deployed. Despite the malicious file remaining active for almost five hours, the period in which funds were compromised is estimated to be less than two hours.
Projects that utilized the affected versions (1.1.5, 1.1.6, and 1.1.7) of the Connect Kit are advised to update to the latest version (1.1.8) to safeguard their assets. Ledger recommends that users “Clear Sign” all transactions, following their instructions, to add an extra layer of security to their wallets.
In response to the security breach, proactive projects such as Kyber and RevokeCash have announced the deactivation of their front ends. This precautionary measure aims to protect users from potential risks associated with the compromised library.
Blockaid, a security firm, has identified the attack on Ledger’s Connect Kit as a supply chain attack. In this type of attack, the intruder replaces the library’s legitimate software with malicious code designed to siphon off assets. Furthermore, Ledger is also warning users about ongoing phishing attacks exploiting the situation. The incident has been linked to a phishing attack on a former Ledger employee, and the company is actively cooperating with law enforcement to apprehend the perpetrator.
This breach serves as a significant reminder of the vulnerabilities present in the web3 space. It emphasizes the necessity for continuous vigilance and swift action to protect digital assets. Users must remain cautious and stay updated with the latest security measures to mitigate the risks associated with these emerging technologies.
The compromised Ledger dApp Connect Kit highlights the critical need for robust security measures in the digital asset space. Ledger’s prompt response and the release of a secure version of the Connect Kit demonstrate their commitment to protecting user funds. However, it is crucial for users to remain proactive in safeguarding their assets and to be aware of potential phishing attacks targeting their wallets. By learning from incidents like this, the digital asset community can collectively work towards creating a more secure environment for the future.
