Socket detects traditional vulnerabilities (CVEs) but goes beyond that to scan the actual code of dependencies for malicious behavior. It proactively detects and blocks 70+ signals of supply chain risk in open source code, for comprehensive protection.
Socket detects and blocks malicious dependencies, often within just minutes of them being published to public registries, making it the most effective tool for blocking zero-day supply chain attacks.
Developers love Socket
Socket is built by a team of prolific open source maintainers whose software is downloaded over 1 billion times per month. We understand how to build tools that developers love. But don’t take our word for it.
Congrats to @feross and the @SocketSecurity team on their seed funding! 🚀 It's been a big help for us at @CoderHQ and we appreciate what y'all are doing!
The best security teams in the world use Socket to get visibility into supply chain risk, and to build a security feedback loop into the development process.

How do you track the validity of open source software libraries as they get updated? You're prob not. Check out @SocketSecurity and the updated tooling they launched.
Supply chain is a cluster in security as we all know and the tools from Socket are "duh" type tools to be implementing. Check them out and follow Feross Aboukhadijeh to see more updates coming from them in the future.
I find it surprising that we don't have _more_ supply chain attacks in software:
Imagine your airplane (the code running) was assembled (deployed) daily, with parts (dependencies) from internet strangers. How long until you get a bad part?
This is an area that I have personally been very focused on. As Nat Friedman said in the 2019 GitHub Universe keynote, Open Source won, and every time you add a new open source project you rely on someone else code and you rely on the people that build it.
This is both exciting and problematic. You are bringing real risk into your organization, and I'm excited to see progress in the industry from OpenSSF scorecards and package analyzers to the company that Feross Aboukhadijeh is building!
Attackers have taken notice of the opportunity to attack organizations through open source dependencies. Supply chain attacks rose a whopping 700% in the past year, with over 15,000 recorded attacks.

Shai Hulud v2
Shai Hulud v2 campaign: preinstall script (setup_bun.js) and loader (setup_bin.js) that installs/locates Bun and executes an obfuscated bundled malicious script (bun_environment.js) with suppressed output.

Elves on npm
A surge of auto-generated "elf-stats" npm packages is being published every two minutes from new accounts. These packages contain simple malware variants and are being rapidly removed by npm. At least 420 unique packages have been identified, often described as being generated every two minutes, with some mentioning a capture the flag challenge or test.

RubyGems Automation-Tool Infostealer
Since at least March 2023, a threat actor using multiple aliases uploaded 60 malicious gems to RubyGems that masquerade as automation tools (Instagram, TikTok, Twitter, Telegram, WordPress, and Naver). The gems display a Korean Glimmer-DSL-LibUI login window, then exfiltrate the entered username/password and the host's MAC address via HTTP POST to threat actor-controlled infrastructure.

North Korea's Contagious Interview Campaign
Since late 2024, we have tracked hundreds of malicious npm packages and supporting infrastructure tied to North Korea's Contagious Interview operation, with tens of thousands of downloads targeting developers and tech job seekers. The threat actors run a factory-style playbook: recruiter lures and fake coding tests, polished GitHub templates, and typosquatted or deceptive dependencies that install or import into real projects.

Network Reconnaissance Campaign
A malicious npm supply chain attack that leveraged 60 packages across three disposable npm accounts to fingerprint developer workstations and CI/CD servers during installation. Each package embedded a compact postinstall script that collected hostnames, internal and external IP addresses, DNS resolvers, usernames, home and working directories, and package metadata, then exfiltrated this data as a JSON blob to a hardcoded Discord webhook.
The GCVE initiative operated by CIRCL has officially opened its publishing ecosystem, letting organizations issue and share vulnerability identifiers without routing through a central authority.
