GitHub on Monday announced a broad plan to reshape how developers authenticate and publish npm packages, citing a wave of supply-chain attacks that have targeted the npm ecosystem and highlighted the risk of token abuse and self-replicating malware. The company said the changes would roll out in the near term as it works with the open-source community to bolster npm security.
The plan includes several core measures: deprecating legacy classic tokens, migrating users away from time-based one-time-password (TOTP) 2FA toward FIDO-based 2FA, and limiting granular publishing tokens to shorter lifetimes. It also calls for disallowing token-based publishing by default, promoting trusted publishers or 2FA-enabled local publishing, removing the option to bypass 2FA for local publishing, and expanding the pool of eligible trusted-publishing providers. 2FA migration to stronger methods and a tightening of granular tokens (which will require seven-day lifetimes) form part of the strategy.
To support these changes, GitHub highlighted that trusted publishing will enable secure npm publishing directly from CI/CD workflows using OpenID Connect (OIDC) and will be accompanied by cryptographic provenance attestations. In their words, “Every package published via trusted publishing includes cryptographic proof of its source and build environment” and users will be able to verify how and where a package was built. Provenance attestations are generated automatically by the npm CLI.
The move comes amid heightened scrutiny of software supply chains. In related actions, the NuGet .NET package repository added support for trusted publishing, and RubyGems announced measures to strengthen governance around gem publishing, with Ruby Central noting that administrative access will be tightened across production and GitHub repositories as policies are finalized.
Security researchers have also flagged threats targeting npm dependencies. Security firm Socket described a malicious npm package named fezbox that used a novel QR-code technique to harvest browser credentials from cookies; the package was removed from npm after attracting hundreds of downloads. The firm noted the actor attempted to fetch a QR code from a remote URL, parse it, and execute a payload designed to exfiltrate cookie-based credentials to an attacker-controlled endpoint. The related analysis and context are available here: Socket security briefing on fezbox and fezbox npm package page. The discovery underscores why dependency checks and provenance verification remain essential for developers.
The security community has also highlighted parallel efforts in other ecosystems. NuGet and RubyGems have moved to bolster trust in publishing across package repositories, with NuGet citing official trusted publishing and RubyGems indicating governance refinements to restrict administrative access during policy implementation.
Developers and security teams are watching closely as the industry adapts to more rigorous publishing workflows. In addition to policy shifts, GitHub and partner platforms emphasize the importance of cryptographic provenance and robust 2FA enforcement as a line of defense against evolving attack techniques.
