"Hackers briefly turned a widely trusted developer tool into a vehicle for credential-stealing malware that could give attackers ongoing access to infected systems," the news site Axios.com reported Tuesday, citing security researchers at Google.
The compromised package — also named axios — simplifies HTTP requests, and reportedly receives millions of downloads each day:
The malicious versions were removed within roughly three hours of being published, but Google warned the incident could have "far-reaching impacts" given the package's widespread use, according to John Hultquist, chief analyst at Google Threat Intelligence Group. Wiz estimates Axios is downloaded roughly 100 million times per week and is present in about 80% of cloud and code environments. So far, Wiz has observed the malicious versions in roughly 3% of the environments it has scanned.
Friday PCMag notes the maintainer's compromised account had two-factor authentication enabled, with the breach ultimately traced "to an elaborate AI deepfake from suspected North Korean hackers that was convincing enough to trick a developer into installing malware," according to a post-mortem published Thursday by lead developer Jason Saayman:
[Saayman] fell for a scheme from a North Korean hacking group, dubbed UNC1069, which involves sending out phishing messages and then hosting virtual meetings that use AI deepfakes to clone the face and voices of real executives. The virtual meetings will then create the impression of an audio problem, which can only be "solved" if the victim installs some software or runs a troubleshooting command. In reality, it's an effort to execute malware. The North Koreans have been using the tactic repeatedly, whether it be to phish cryptocurrency firms or to secure jobs from IT companies.
Saayman said he faced a similar playbook. "They reached out masquerading as the founder of a company, they had cloned the company's founders likeness as well as the company itself," he wrote. "They then invited me to a real Slack workspace. This workspace was branded... The Slack was thought out very well, they had channels where they were sharing LinkedIn posts. The LinkedIn posts I presume just went to the real company's account, but it was super convincing etc." The hackers then invited him to a virtual meeting on Microsoft Teams. "The meeting had what seemed to be a group of people that were involved. The meeting said something on my system was out of date. I installed the missing item as I presumed it was something to do with Teams, and this was the remote access Trojan," he added. "Everything was extremely well coordinated, looked legit and was done in a professional manner."
Friday developer security platform Socket wrote that several more maintainers in the Node.js ecosystem "have come out of the woodwork to report that they were targeted by the same social engineering campaign."
The accounts now span some of the most widely depended-upon packages in the npm registry and Node.js core itself, and together they confirm that axios was not a one-off target. It was part of a coordinated, scalable attack pattern aimed at high-trust, high-impact open source maintainers. Attackers also targeted several Socket engineers, including CEO Feross Aboukhadijeh. Feross is the creator of WebTorrent, StandardJS, buffer, and dozens of widely used npm packages with billions of downloads... Commenting on the axios post-mortem thread, he noted that this type of targeting [against individual maintainers] is no longer unusual... "We're seeing them across the ecosystem and they're only accelerating."
Jordan Harband, John-David Dalton, and other Socket engineers also confirmed they were targeted. Harband, a TC39 member, maintains hundreds of ECMAScript polyfills and shims that are foundational to the JavaScript ecosystem. Dalton is the creator of Lodash, which sees more than 137 million weekly downloads on npm. Between them, the packages they maintain are downloaded billions of times each month. Wes Todd, an Express TC member and member of the Node Package Maintenance Working Group, also confirmed he was targeted. Matteo Collina, co-founder and CTO of Platformatic, Node.js Technical Steering Committee Chair, and lead maintainer of Fastify, Pino, and Undici, disclosed on April 2 that he was also targeted. His packages also see billion downloads per year... Scott Motte, creator of dotenv, the package used by virtually every Node.js project that handles environment variables, with more than 114 million weekly downloads, also confirmed he was targeted using the same Openfort persona.
Socket reports that another maintainer was targetted with an invitation to appear on a podcast. (During the recording a suspicious technical issue appeared which required a software fix to resolve....)
Even just technical implementation, "This is among the most operationally sophisticated supply chain attacks ever documented against a top-10 npm package," the CI/CD security company StepSecurity wrote Tuesday
The dropper contacts a live command-and-control server, delivers separate second-stage payloads for macOS, Windows, and Linux, then erases itself and replaces its own package.json with a clean decoy... Three payloads were pre-built for three operating systems. Both release branches were poisoned within 39 minutes of each other. Every artifact was designed to self-destruct. Within two seconds of npm install, the malware was already calling home to the attacker's server before npm had even finished resolving dependencies... Both versions were published using the compromised npm credentials of a lead axios maintainer, bypassing the project's normal GitHub Actions CI/CD pipeline.
"As preventive steps, Saayman has now outlined several changes," reports The Hacker News, "including resetting all devices and credentials, setting up immutable releases, adopting OIDC flow for publishing, and updating GitHub Actions to adopt best practices."
The Wall Street Journal called it "the latest in a string of incidents exposing risks in the systems that underpin how modern software is built."
