Removed from pypi
Blocked by Socket
The code contains high-risk unsafe behavior: exec() is used to run Python code derived directly from OpenAI function_call arguments with no sandboxing or validation, and os.system is invoked with formatted user-controlled inputs — both lead to remote code execution / command injection possibilities. There are no signs of obfuscation or explicit malicious payloads, so this is likely insecure/unsafe design rather than intentionally stealthy malware. Treat this module as dangerous in production: remove or strictly sandbox any use of exec on external content, validate/escape inputs passed to os.system (or use subprocess with argument lists), and restrict privileges/contexts where such execution is allowed.

Blocked by Socket
The bundled script contains an intrusive, targeted payload: when running in a browser with Russian locale on a .ru/.su/.xn--p1ai host and more than 3 days after a stored initiation time, it disables page interaction and injects/auto-plays looping audio from an external domain (flag-gimn.ru). This is an abusive UX hijack and constitutes a supply-chain compromise or deliberate tampering. It should be removed and the package/source verified before use.

The code exhibits several suspicious behaviors, including obfuscation, potential data exfiltration, silent error handling, and system fingerprinting. While direct malicious intent (e.g., malware payload delivery, system damage) isn't explicitly evident in the provided snippet, the overall pattern and coding practices suggest a high likelihood of being part of a larger malicious operation or having the capability to perform unauthorized actions. Caution is advised.

Live on pypi
Blocked by Socket
The code exposes powerful administrative actions: arbitrary shell execution, arbitrary file reads, full environment dumps, and building/pushing Docker images to a hardcoded registry. These are not obfuscated but are high-risk capabilities that can be abused for data exfiltration, remote code execution, and supply-chain leakage if the superuser authentication is compromised or misconfigured. The presence of a hardcoded remote image name for docker push is suspicious for unintended outbound artifact exfiltration. Recommendation: avoid including these endpoints in public packages or ensure strict, auditable authentication and input validation; remove hardcoded push targets and avoid returning full environment variables or arbitrary file contents.

Live on go
Blocked by Socket
This Go source contains routines that speak the T3 protocol to connect to Oracle WebLogic servers and deploy a serialized-Java RMI backdoor. It checks for the presence of a class named “com.supeream.payload,” installs a malicious payload if absent, then invokes arbitrary OS commands on the target and can clean up the backdoor afterward. Payload templates reference a default endpoint t3://47[.]104[.]229[.]232:7001, which is dynamically replaced with the victim IP/port. The hex-encoded Java object streams hide the backdoor installer/uninstaller and command execution logic, representing a high-severity malware threat.

Live on maven
Blocked by Socket
This class is a backdoor/memshell implant. It triggers on a custom HTTP header and Content-Type and implements a custom binary protocol to create and manage remote connections, proxy TCP streams, and forward/marshal data. It disables SSL validation, enumerates local network interfaces, and allows attacker-controlled outbound connections to arbitrary hosts/ports and HTTP(S) endpoints, enabling data exfiltration, SSRF and lateral movement. This is malicious and should be treated as a high-risk supply-chain compromise; remove and investigate any systems where it is present.

Live on pypi
Blocked by Socket
This code fragment is an abusive 'SMS BOMBER' tool. It contains dangerous primitives (network capability via requests, arbitrary shell execution via os.system, and external URL opening) and is explicitly intended to send bulk SMS/calls to targets. Even though the snippet is syntactically broken and incomplete, its intent is malicious. It should not be used and should not be included as a dependency. If encountered in a package repository or dependency tree, treat as high risk: remove or block and investigate supply-chain exposure.

This is not benign library code; it is an exploitation module that performs network probing and cookie bruteforcing against a specific class of embedded device, then extracts and discloses recovered password material from an HTTP management interface. While it is not obfuscated, its clear credential-theft/exploitation capability makes it high-risk if distributed as part of a supply chain dependency without strict isolation and explicit user authorization.

The code is a clear security threat exhibiting malicious behavior: it exfiltrates sensitive environment variables to a suspicious external server and executes arbitrary code received from that server. The obfuscation and use of eval confirm intent to hide this backdoor functionality. This module should be considered malware and avoided.

Live on actions
Blocked by Socket
The script enables a plausible supply-chain attack by allowing an attacker-controlled binary provided via $1 to be copied into the Cargo bin directory and used to shadow or replace cargo-binstall during self-update cycles. The lack of integrity checks, input validation, and signature verification significantly elevates risk, making remote code execution or persistent backdoors feasible through trusted tooling. Recommendation: prohibit overwriting core tooling, verify hashes/signatures of all binaries, validate the origin of $1, and remove or constrain the ability to modify CARGO_HOME/bin during tool updates.
sbcli-dev
5.0.2
Live on pypi
Blocked by Socket
No direct malware code is present in the fragment (no obvious backdoor, reverse shell, or exfiltration implemented in this file itself). However, the module exposes very high-risk functionality: it connects to the Docker API over plaintext TCP, allows client-controlled image pulls and runs containers as privileged with host mounts and host networking, and injects potentially sensitive credentials into container environments. These behaviors make this code a significant supply-chain and host compromise risk if the endpoints are reachable by untrusted users or if DOCKER_IP/docker daemon is exposed. Recommend restricting access, enforcing authentication/authorization, validating image names (or disallowing arbitrary images), using TLS/auth for Docker daemon, removing privileged/host_mode mounts where possible, and avoiding passing untrusted secrets into container environments.

Live on nuget
Blocked by Socket
This file contains an obfuscated runtime loader/unpacker that reads embedded/encrypted bytes, decrypts them with a hard-coded symmetric key/IV, allocates and writes memory, manipulates other process memory and modules, creates delegates from function pointers and invokes them. Those behaviors are classic indicators of in-memory code injection / runtime shellcode loading. The code is heavily obfuscated, includes direct Win32 API use for memory manipulation and process memory writes, and contains hard-coded crypto keys — all of which represent high risk for supply-chain malicious behavior or a backdoor/loader. I assess this module as malicious or at least highly suspicious and dangerous; it should be treated as untrusted and strongly reviewed/removed from trusted builds.

Blocked by Socket
This module intentionally hides a large code payload and executes it via eval after XOR-decoding with a hardcoded key. That behavior enables arbitrary hidden actions (network, file, process, credential access) and is a high-risk supply-chain indicator. Treat this package as untrusted until the decoded payload is extracted and analyzed in a safe sandbox. Immediate mitigation: do not install/run; extract and inspect decoded code offline; consider removing or replacing the dependency.

This module is a high-risk runtime packer/dropper: it embeds an encrypted payload, decrypts it using a user-supplied passphrase, writes the result to `bin/do-setup-circleci-secrets`, and immediately executes it. Because there is no integrity/authenticity validation of the decrypted artifact and the executed code is not shown here, the module should be treated as potentially malicious until the decrypted `bin/do-setup-circleci-secrets` content is inspected and validated in a safe environment.

The package.json itself does not contain explicit shell commands that exfiltrate data or launch reverse shells, but the defined install lifecycle is high-risk: it automatically installs many global tools and includes a step that copies node_modules from the global npm root into the local project. These behaviors have strong supply-chain and host-integrity implications (unexpected global modifications, potential use of attacker-controlled global packages, privilege escalation prompts). Treat this install script as dangerous: do not run npm install on this package in production or on sensitive hosts without reviewing and removing the install lifecycle scripts or running in an isolated environment.

Blocked by Socket
This module is an automation/scraping worker that intentionally executes code provided by task descriptions. That design requires trusting the task source. The code contains multiple high-risk sinks: subprocess with shell=True, exec()/eval of task-supplied code, and browser JS execution. It also copies browser user profiles (cookies/credentials) into temporary profiles, which increases risk of credential theft. If task inputs are untrusted (remote server controlled by attacker or tampered local JSON), an attacker can achieve remote code execution, data exfiltration (files, cookies), or arbitrary system changes. Recommendation: only run with tasks from trusted sources, disable remote task fetching unless secured, avoid copying full user-data profiles, and remove/guard exec/eval/subprocess paths or run worker inside a hardened sandbox/container with least privileges.

This module implements an automated SSH-based file exfiltration plugin. It uses harvested credentials to connect to SSH services, optionally escalates using sudo, enumerates and expands directories/wildcards, and retrieves and persists highly sensitive files (including /etc/shadow and sudoers). In an offensive/CTF context this behavior is likely intended; in any benign or multi-tenant environment this constitutes a serious supply-chain and insider threat risk. If you are evaluating this package for inclusion in production software, treat it as malicious-capability code: restrict its presence to isolated, audited environments, review and lock down configuration, and audit helper functions and storage to prevent unintended data theft.

The package will run postinstall.js during npm install which grants it the ability to perform arbitrary actions on the host. The self-dependency on the same package name/version is a suspicious indicator of potential tampering or a forced install trick. No obvious non-registry dependency sources or plain-HTTP URLs are present. To determine if this package is malicious, inspect the contents of postinstall.js and setup-cli.js and verify the reason for the self-dependency. Until those files are reviewed, treat install as high-risk.

If software supply chain attacks through npm don't scare the shit out of you, you're not paying close enough attention.
@SocketSecurity sounds like an awesome product. I'll be using socket.dev instead of npmjs.org to browse npm packages going forward

Elena Nadolinski
Founder and CEO at Iron Fish
Huge congrats to @SocketSecurity! 🙌
Literally the only product that proactively detects signs of JS compromised packages.

Joe Previte
Engineering Team Lead at Coder
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!

Josh Goldberg
Staff Developer at Codecademy
This is such a great idea & looks fantastic, congrats & good luck @feross + team!
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.

As a happy Socket customer, I've been impressed with how quickly they are adding value to the product, this move is a great step!

Yan Zhu
Head of Security at Brave, DEFCON, EFF, W3C
glad to hear some of the smartest people i know are working on (npm, etc.) supply chain security finally :). @SocketSecurity

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.

socket.dev is getting more appealing by the hour

Devdatta Akhawe
Head of Security at Figma
The @SocketSecurity team is on fire! Amazing progress and I am exciting to see where they go next.

Sebastian Bensusan
Engineer Manager at Stripe
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?
Excited for Socket to prevent this

Adam Baldwin
VP of Security at npm, Red Team at Auth0/Okta
Congrats to everyone at @SocketSecurity ❤️🤘🏻

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!

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.
