In reaction to the Sha1-Hulud incident, npm finished a significant authentication overhaul in December 2025 with the goal of lowering supply-chain attacks This article explores chainguard javascript repository. . Even though the overhaul is a positive step, supply-chain attacks can still affect npm projects.

Here are some tips for a safer Node community because npm is still vulnerable to malware attacks. ## Let's begin with the initial issue. In the past, npm has depended on classic tokens, which are credentials with a broad scope and a long lifespan that can last forever. Attackers could upload malicious versions to the author's packages directly if they were stolen; publicly verifiable source code is not required.

Because Chainguard's JavaScript repository would never publish the malicious versions available on npm, building from source would, according to historical data, reduce your attack surface by about 98.5%. In a perfect world, users who use Chainguard Libraries and follow the above advice are the most secure. According to the "Swiss cheese model of security," businesses would be better off utilizing a combination of these features, which are all layers of additive security measures.
