Kofi Mensah The recent exploit of Ledger’s Connect Kit, a Javascript library essential for wallet connectivity, on December 14, 2023, has sparked widespread criticism regarding Ledger’s security protocols. Despite being swiftly addressed within two hours, this breach has raised significant concerns about Ledger’s approach to software security.
Ledger’s Security Breach: A Cause for Alarm in the Crypto Community
Ledger, a company renowned for its cryptocurrency security solutions and hardware wallets, experienced a security breach in its Ledger Connect Kit. This Javascript-based tool, which facilitates the integration of websites with wallets, encountered a breach that lasted under two hours. While the hardware wallets and Ledger Live platform remained unaffected, the exploit targeted third-party decentralized applications (dapps) that utilized the Connect Kit. This incident has prompted a reassessment of Ledger’s software security measures.
Jameson Lopp, the CTO of bitcoin security firm Casa and a respected figure in the cryptocurrency community, identified three key failures in Ledger’s security approach: the indiscriminate loading of code without specific version pinning and checksum verification, the absence of dual-control (‘2 man rules’) in code review and deployment processes, and the failure to terminate access for former employees.
The exploit was initiated through a phishing attack on a former employee, leading to the insertion of malicious code into Ledger’s NPMJS repository. Lefteris Karapetsas, another critic, condemned Ledger’s decision to build a security-sensitive library with the convenience of ‘loading from CDN’, bypassing the need for dapps to update.
An industry commentator, Cryptofinally, remarked on the audacity of the exploit, where the perpetrator, a former Ledger employee, left identifiable information within the code.
Ledger’s Response and Future Measures
In response, Ledger’s CEO Pascal Gauthier recognized the breach and detailed steps to bolster security. Gauthier admitted, “This was a regrettable, isolated incident. It underscores that security is an ever-evolving challenge, and Ledger must constantly enhance our security framework.” The company plans to introduce stricter controls, particularly in software supply chain security, to prevent similar incidents.
Ledger is collaborating with law enforcement and cybersecurity specialists to trace the stolen assets and assist impacted users. Gauthier expressed regret over the incident’s impact on individuals and reassured the crypto community that the threat has been neutralized. He shared a comprehensive timeline of the incident and Ledger’s response actions.
Industry Reaction and Proactive Measures
Following the Ledger exploit, several dapps and cryptocurrency organizations promptly took protective measures. Many protocols and companies temporarily disabled their front-end interfaces as a precautionary step. Among those responding were Lido, Sushi, Balancer, Revokecash, Zapper, and the NFT marketplace Opensea. Additionally, Tether’s CEO Paolo Ardoino announced that the stablecoin company had frozen the exploiter’s address to prevent further damage.
Arkham Intelligence announced a bounty for information leading to the identification of those responsible for the Ledger Library Drainer Exploit, known as “Angel Drainer.” This exploit resulted in a loss exceeding $500K across multiple dapps. The bounty, similar to the one offered after the Okx Dex incident, includes rewards for revealing the identity of Angel Drainer, leads on fund recovery, and information on any KYC exchange deposits made post-incident.

Honestly, how do you not revoke x-employee access?? That’s like cybersecurity 101, Ledger really dropped the ball here
just read about the Ledger exploit, really shocking how even big firms can mess up security..guess no ones safe!
Can’t believe they caught the guy cause he left his name in the code, talk about a rookie mistake, lol
Ledger’s CEO seems to be taking it seriously but, they really should’ve had better controls in place from the start
This whole incident just shows how important it is to stay vigilant, even in crypto which supposed to be secure n all.
