the WORST hack of 2026

Axios, the most popular HTTP library with over 100 million weekly downloads, was just hijacked in one of the most sophisticated supply chain attacks in history. A hacker took over the lead maintainer's npm account, injected a phantom dependency that deploys a cross-platform remote access trojan in 1.1 seconds, and the malware erases itself leaving no trace. I break down exactly how it happened, explain what a supply chain attack is, and show you how to check if YOUR system is affected.

This video covers a major supply chain attack targeting the popular npm package Axios, which impacted over 100 million weekly downloads. The attack occurred when a malicious actor gained access to a lead maintainer's account and injected a compromised dependency, turning the standard npm install command into a security risk.

Key Highlights of the Attack:

  • The Mechanism (2:20 - 3:30): Instead of modifying Axios code directly, the attacker added a hidden dependency called plain-crypto-js. This phantom package contained a postinstall script that triggered a downloader.
  • Malware Execution (3:40 - 4:40): Upon installation, the malware would identify the OS, download a Remote Access Trojan (RAT) within 1.1 seconds, and then delete all evidence of its presence, leaving the system compromised without a trace.
  • Scope and Discovery (3:06 - 3:20): Versions 1.14.1 and 0.30.4 were confirmed as malicious. The attack was first identified by Socket.dev.

How to Check Your System:

  • Verify Installed Versions: Run npm list axios or npm list -g axios (6:09 - 6:15). If you see the bad versions mentioned above, your system may be at risk.
  • Remediation (6:51 - 7:06): If you find these versions, do not just delete the files. Treat your machine as compromised, rotate all API keys, and update all credentials.
  • Prevention: The creator suggests using npm config set min-release-age 3 as a safeguard against similar future attacks.
 
This attack was pretty blunt. Once the attacker has access to the developer's Github account, they started inserting the malicious code without trying to cover their tracks. It raised red flags almost immediately which is why it was shut down just 3 hours after the first malicious code was injected into the system.

However these supply chain hacks are going to become more and more frequent and harder and harder to identify and stop prior to execution. For example, I watched a video recently on how XZ (an extremely popular data compression tool) was subject to a much sneakier supply chain hack in 2021. The hack was ended up being included in beta versions of common Linux versions and it was only accidentally discovered just before it was to be included in the official releases of the major Linux versions. By all accounts, if one person hadn't realized there was a tiny bit of added latency and didn't give up on finding out why, the hackers would have had unfettered access to basically every Linux server on the internet once the beta versions went mainstream. Given that the vast majority of servers run Linux, this would have been catastrophic. The evidence points to the hack being state sponsored (by China).
