Charles Guillemet Warns of Crypto Supply Chain Attack
Ledger CTO Charles Guillemet warns of a crypto-focused supply chain attack via NPM packages, putting millions of users at risk.
- Ledger CTO warns of supply chain threat to crypto
- NPM packages with 1B+ downloads compromised
- Hackers aim to steal wallet keys and assets
Charles Guillemet, the CTO of Ledger, has sounded the alarm on a major crypto supply chain attack that could impact millions. According to his recent statement, attackers have compromised widely used NPM (Node Package Manager) packages, some of which have over 1 billion downloads. These packages are now being weaponized to steal cryptocurrency from unsuspecting users and developers.
The attack has the potential to affect web apps, browser extensions, and even backend tools used by crypto platforms. The goal? To quietly extract private keys and drain digital wallets through malicious code injected into commonly used software packages.
How Developers and Users Are at Risk
NPM packages are essential building blocks for many crypto applications. When even one of these packages is compromised, it can affect every project that depends on it — from small tools to large exchanges.
The malicious code is often subtle and hidden deep within updates or dependencies, making it hard to detect. For end users, this could mean that simply using a web wallet or interacting with a dApp could expose their funds to theft.
This kind of supply chain attack is especially dangerous because it targets the foundation of modern software: open-source collaboration.
Guillemet Urges the Crypto Industry to Act
Charles Guillemet is urging the entire crypto community — from developers to end users — to take the threat seriously. He recommends strict code auditing, securing development pipelines, and using hardware wallets to minimize exposure.
For users, sticking with trusted software and avoiding browser wallets is crucial. Using hardware wallets like Ledger ensures your private keys stay offline and out of reach from such attacks.
The growing frequency of software supply chain compromises proves that even the best cryptography can’t protect users if the software handling it has been tampered with.
