Blocked by Socket
This file implements core C2 implant behaviors: remote interactive shell spawning and arbitrary TCP port forwarding driven by protobuf messages from a controller. Sources are untrusted network messages and sinks include spawning OS processes and sending data back to the controller (exfiltration) as well as dialing arbitrary remote hosts (proxying). The code lacks input validation and contains concurrency risks (unsynchronized global cache). In a supply-chain context this is high-risk and likely malicious functionality (implant/C2). If the package is included as a dependency in benign software this represents a severe supply-chain risk and should be treated as malicious unless explicitly required and audited.
dploot
3.1.3
Live on pypi
Blocked by Socket
dploot is Python rewrite of SharpDPAPI written un C# by Harmj0y, which is itself a port of DPAPI from Mimikatz by gentilkiwi. It implements all the DPAPI logic of these tools, but this time it is usable with a python interpreter and from a Linux environment. It is meant to be an offensive security tool. It should not be used as a dependency in a production environment. This module implements a credential harvesting system that remotely extracts sensitive browser data from Windows user profiles via SMB connections. It targets Chromium-based browsers (Chrome, Edge, Brave) by reading Local State, Login Data, Cookies, and Web Data files, then decrypts stored passwords, cookies, and Google refresh tokens using DPAPI masterkeys and app-bound key handling. The code contains hardcoded AES and ChaCha20 cryptographic keys (aes_key: B31C6E241AC846728DA9C1FAC4936651CFFB944D143AB816276BCC6DA0284787, chacha20_key: E98F37D7F4E1FA433D19304DC2258042090E2D1D7EEA7670D41F738D08729660) used for decrypting app-bound encrypted payloads. The module enumerates all users on the target system and systematically harvests credentials across multiple browser profiles. Extracted secrets are exposed through configurable callbacks (per_loot_callback) that enable data exfiltration, stdout printing that may leak sensitive data to logs, and return values for programmatic access. This represents a complete credential theft capability designed for post-exploitation scenarios and unauthorized data harvesting.

High risk. The postinstall hook executes a local setup script that must be audited before installing. The declared dependency that is identical to the package name is abnormal and potentially malicious or a packaging error; it increases supply-chain risk because it may cause npm to fetch an external package/version unexpectedly. Treat this package as suspicious until scripts/setup.js is reviewed and the self-dependency is explained or removed.

Removed from pypi
Blocked by Socket
This module is intentionally obfuscated and executes a large embedded payload at import time. That design is a strong supply-chain/malicious indicator: executing compressed/reversed/base64-encoded code without any verification is dangerous. Even if the embedded payload is benign, the pattern prevents easy review and allows arbitrary harmful behavior (data theft, backdoors, remote code execution, file system damage, etc.). Treat this package as untrusted until the decompressed payload is decoded and reviewed. If this appears in a dependency, remove or quarantine it and obtain a human-reviewed, provenance-verified replacement.

This module implements an automatic downloader-and-executor (dropper/stager). Importing the module triggers a PowerShell command that downloads an executable from a hard-coded remote HTTP URL to ProgramData and runs it hidden. The behavior is strongly indicative of malicious intent or at minimum extremely risky and inappropriate for safe libraries: it enables arbitrary remote code execution, performs covert installation, and provides no integrity checks or user consent. Do not import or use this module. Treat as malicious: remove, block the domain, and investigate any hosts where this code ran.

This module is highly suspicious and should be treated as high-risk from a supply-chain/security perspective. The most concerning aspect is server-side injection of a substantial inline client-side JavaScript payload into proxied/served HTML, with apparent network/proxy/WebSocket-like behavior and route-based interaction. Combined with container exec-based environment-variable extraction and ${...} substitution that can feed into the injected payload and headers, it creates a plausible backdoor/persistent-agent pattern. Full remediation requires deobfuscating the injected script, enumerating all endpoints it contacts, and auditing/locking down container exec usage and all inputs used for HTML/header generation.

Live on npm
Blocked by Socket
This module contains a high-impact supply-chain and execution risk: it performs an automatic runtime download of JavaScript from a public CDN and executes it via eval() to bootstrap the command runner. That establishes a straightforward path to arbitrary code execution under the CLI’s privileges. It further shells out to codex and git through dynamically constructed pipelines using caller-influenced values, and it invokes codex with explicit “dangerously bypass” flags. Even if the intent is orchestration, the implementation should be treated as unsafe unless the runtime eval bootstrap is removed or cryptographically pinned/verified and command arguments are strictly validated/escaped.

This module is explicitly adversarial and returns actionable suggestions that, if consumed and executed without strict validation and authorization, can lead to privilege escalation, unauthorized financial actions, or disruptive incident-response behavior. The file does not itself perform I/O or network activity, but it is a dangerous supply-chain component: treat it as malicious/instrumental in adversarial steering and do not allow automated execution of its outputs without strong governance (human review, authorization checks, parameter validation, and mapping of endpoints to a safe execution policy).

The dominant security concern is the explicit use of eval on data-derived JSON within CarbonPHP.handlebars, which can enable arbitrary code execution if data is attacker-controlled. Additional concerns include unsanitized dynamic script/template loading and a busy-wait sleep that can degrade performance and potentially expose timing information. Overall risk is high due to the eval pattern and dynamic content loading without strong sanitization.

This module functions as a high-fidelity interaction capture component: it globally listens for keyboard and form/input-related events, captures e.key and input values (with minimal truncation rather than redaction), enriches events with DOM text and computed XPath identifiers, and sends all data to a Chrome extension via runtime messaging, along with page URL/title. While no external networking is shown here, the collected data types are highly sensitive and the behavior strongly aligns with keylogging/form-data harvesting use cases. The receiving extension logic and declared permissions should be reviewed urgently for consent, scope, minimization, and any external exfiltration.

Live on npm
Blocked by Socket
This module contains multiple security issues and at least one explicit indication of malicious intent. The error handler reflects util.inspect(err) into HTML responses (information disclosure and possible XSS) and interpolates authenticationUrl without validation. Most notably, the loginSuccess() page contains the text 'Sucessfully grabbed credentials!', which is a clear red flag — it strongly suggests the page is intended to display harvested credentials or confirm credential theft. Even if other parts are benign, the presence of that message plus unsafe leak of inspected error objects to clients makes this package unsafe to use. Recommend not using this code in production, auditing the repository for credential-harvesting behavior, removing util.inspect() from client responses, and validating/escaping any interpolated URLs and strings.

This module contains a critical vulnerability: unconstrained eval() of attacker-controlled 'input.expr' with access to local variables (including a formatted request object). This yields remote code execution and potential data exfiltration. The code likely represents an insecure design/bug rather than intentionally malicious code, but it must be remediated before handling untrusted inputs. Also fix the apparent syntax error in getAttr.

The script is a convenience bootstrapper but implements high-risk supply-chain and remote code execution patterns: installing unpinned npm packages (which may run lifecycle scripts) and piping a remote script from raw.githubusercontent.com directly into node without integrity checks. The script itself is not obfuscated and contains no embedded payloads, but it creates a simple, reliable path for arbitrary code execution and potential credential theft/exfiltration if either the remote cfat.js or any installed package is compromised. Do not run this script in sensitive or production environments without first: (1) fetching and auditing the remote cfat.js locally, (2) pinning and auditing exact package versions (use a lockfile), (3) verifying artifact integrity (checksums/signatures/pinned commit SHA), and (4) executing in a constrained environment (sandbox, least-privilege account).

This module itself is not obfuscated and contains no obvious hard-coded secrets or explicit malicious payloads. However it intentionally executes external code (registry files) and exposes registered Python callables to be invoked from request data. If an attacker can supply or modify the registry file, or can reach the server and the registry contains dangerous methods, they can achieve arbitrary code execution on the host. Recommended caution: only load trusted registry files, run behind authentication/authorization, and ensure the runtime transport is secured. For untrusted environments, treat this as high-risk functionality.

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 ❤️🤘🏻

CISO at Lyft
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.
