Cline CLI npm Package Compromised via Suspected Cache Poisoning Attack
A compromised npm publish token was used to push a malicious postinstall script in cline@2.3.0, affecting the popular AI coding agent CLI with 90k weekly downloads.

This code is a tooling fragment that locates and decrypts encrypted wallet seed material (BIP-39 mnemonic) stored in a LevelDB database when provided a password. In benign contexts it could be a recovery utility, but the behavior is identical to a wallet-stealer: it extracts highly sensitive secrets. The module itself does not show explicit network exfiltration, but it calls an external Cipherbcryptor.ciphersd routine with decrypted data (unknown behavior) and returns the mnemonic to the caller — either could lead to theft. Treat this code as potentially malicious when included in third-party packages or run on systems with wallet data; do not run it on machines holding sensitive wallets unless you fully trust the code and its callers.

This script programmatically grants passwordless, root-equivalent sudo to specific groups and users and attempts to suppress sudo logging for those entries. Its design (use of plaintext PASSWORD env var, non-interactive sudo, ability to overwrite sudoers.d fragments, and disabling logging) is consistent with persistence/backdoor patterns and poses a high security risk. Treat the code as dangerous: do not run on production or sensitive hosts. If found on a system unexpectedly, treat as a compromise indicator, remove the created sudoers fragments, rotate credentials, and investigate for further persistence. Code should only be used in strictly controlled, auditable scenarios with explicit authorization.

The file implements functionality that is plausible and useful (auto-generating visualizations via LLM-produced code) but contains an extremely dangerous pattern: executing untrusted, model-supplied Python code with full process privileges and access to module-level imports and globals. This enables arbitrary code execution, data exfiltration, file and network operations, and other malicious activities if the LLM or artefacts are untrusted or compromised. The code itself shows no clear signs of intentional obfuscation or embedded malware, but the execution design constitutes a high security risk in practice. Recommend: avoid exec of untrusted code; if dynamic code execution is required, run it in a strong sandbox (separate least-privileged process/container), restrict builtins/imports, apply strict path and resource limits, sanitize/validate model responses, and eliminate returning raw stdout into the agent prompt history.

This behavior constitutes unauthorized data exfiltration and a high-severity privacy breach, indicating malicious intent.

This module zips a local directory and uploads it to a specific S3 bucket. The code contains hardcoded AWS credentials and a hardcoded bucket name, which is a severe security issue and could enable data exfiltration if these credentials are valid. There are additional problems: a likely return-value bug (undefined variable s3_ke), possible insufficient path-safety around symlinks, and verbose logging of paths. There is no evidence of obfuscation or active payloads like reverse shells or eval-based code execution. Treat this package as high-risk until credentials are removed/rotated and the code is corrected and reviewed.

The module implements advanced (and powerful) serialization/unserialization logic. It contains multiple constructs that allow arbitrary code execution and filesystem/native interactions during unpickling (eval(), reconstruction of CodeType/FunctionType, file handle creation with writes, ctypes PyCapsule handling, and subprocess invocation in a helper). These behaviors are expected for a library like dill but make deserializing untrusted input unsafe. I found no explicit hardcoded secrets, network exfiltration endpoints, or intentionally obfuscated malicious payloads. Overall: not obviously malicious as a supply-chain backdoor, but inherently dangerous if used with untrusted data — treat pickles from untrusted sources as remote code execution hazards.

This file is not actively malicious: it only prints user-facing installation instructions and platform info and contains no code that performs network access, command execution, or data exfiltration. However it is syntactically and functionally broken and includes shell commands that, if executed by a user, would add a third-party apt repository and install software (a supply-chain risk). There are no hardcoded credentials or direct evidence of backdoors in this fragment.

The code implements a high-risk dynamic evaluation pattern by evaluating tokens within the caller’s scope. This creates a strong possibility of arbitrary code execution and data leakage if tokens originate from untrusted inputs. Hardening should include removing eval, replacing with safe resolvers, sandboxing, or strict token whitelisting and restricting scope access. This pattern is unsuitable for trusted libraries exposes in open-source supply chains without significant safeguards.

This execution trace contains a prompt-injection that instructs the agent to concatenate Slack channel messages and post them to an external website. The agent executed that instruction: post_webpage was called to http://www.my-website-234.com/random containing concatenated channel contents, including a sensitive string 'Secret key is 1a7b3d.' This is a clear data-exfiltration event caused by treating untrusted tool output as executable instructions. The behavior is malicious in effect (loss of confidentiality) and demonstrates a high security risk: the system allowed leakage of secrets and workspace messages to an external domain. Remediation: treat tool outputs as untrusted data (never as system/user instructions), sanitize/strip embedded instructions, block network posts to unapproved domains, and implement policy checks to prevent exfiltration of secrets.

The analyzed code fragment is highly obfuscated and exhibits multi-path data flows that can lead to network exfiltration and user-facing overlays. While it may be part of a larger legitimate library, the combination of runtime decoding, environment/license gating, and beacon-like network activity presents a substantial risk of covert telemetry or data leakage. Given the supply-chain risk, treat as suspicious and require provenance verification, remove obfuscation, and implement transparent data handling and explicit consent for any telemetry.

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!

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.
