- Hack of Ledger’s NPM JavaScript connector enabled $500K crypto drain from decentralized apps after former employee phished
- CEO Pascal Gauthier contends unaffected core systems have robust security controls that will now extend to supply chain elements
- Despite calling hack an isolated incident, Gauthier vows enhanced software supply chain oversight to match protections governing most infrastructure
Hardware wallet provider Ledger suffered a cyber intrusion this week that compromised one of its JavaScript connector libraries for nearly two hours. CEO Pascal Gauthier contends it was an isolated incident and has outlined security improvements to prevent recurrence.
My personal commitment: Ledger will dedicate as much internal and external resources as possible to help the affected individuals recover their assets.

On December 14th, an unnamed former employee fell prey to a phishing attack, resulting in their credentials being leveraged to insert malicious code into Ledger’s NPM distribution channel. This enabled the hacker to target Ledger connection integration with decentralized apps.
According to Gauthier, over 99% of Ledger’s infrastructure mandates multi-party code reviews and access controls that would have blocked such an intrusion. But this specific library setup lacked those controls – an oversight that he called an “unfortunate isolated incident”.
The exploit was quickly discovered and deactivated within 40 minutes. Gauthier confirmed Ledger hardware and the Live platform itself remained fully insulated from infringement. Nonetheless, over $504,000 in funds were reportedly drained.
In response, Ledger promises to implement much stronger oversight procedures around its NPM pipeline, enforcing strict software supply chain standards to match the security layers insulating most of its other code base and systems.
While emphasizing any organization is vulnerable to such phishing-enabled attacks, Ledger says lessons are learned.

The compromised library has already been updated and secured. And Ledger intends to lead security innovation in the crypto asset industry.
The relatively prompt detection and transparent disclosure of Ledger’s exploit is reassuring. However, robust software supply chain safeguards should become standard, especially given the surging integration of crypto into mainstream finance. High profile responses can spur emulation – an opportunity Ledger now bears in boosting security consciousness.
