SafeDep analyzed sckit (the "supplychain.local worm"), a previously unreported cross-platform Go implant framework found on September 23, 2026 in the compromised MemTensor packages @memtensor/email protected (npm) and email protected (PyPI). It harvests credentials from developer machines and CI jobs, takes signed tasks from a C2 server, …
Unit 42 researchers found that in default AWS AgentCore Harness deployments, prompt injection can steer the agent's built-in shell tool to exfiltrate plaintext credentials resolved from AgentCore Identity. The shell tool is enabled by default and runs as root, in the same UID as the harness runtime (PID 1, python3.10 -m loopy.server). Tha…

SafeDep flagged the malicious npm package ulid-xyz in June 2026. It typosquats ulidx and is a cross-platform remote access trojan. It is delivered through a three-layer transitive dependency chain: ioredis-xyz (a clone of the legitimate ioredis client) depends on redis-type-xyz (an empty manifest posing as Redis OM), which in version 1.10…
A malicious version 0.7.4 of the mrmustard photonic quantum computing library (Xanadu) was published to PyPI on July 23, 2026, after the account of the project's lead maintainer (ziofil, Filippo Miatto) was compromised. Importing the package reads SSH private keys, AWS credentials and the Kubernetes config, then sends them to an attacker-…
Kaspersky analysis of an installer first classified as adware (MD5 c24e99f9437feacaa63766a3cde3fe3d) found that it delivers the ValleyRAT backdoor. The installer drops a modified, signed Chinese wallpaper tool, QN Wallpaper, and uses it for DLL sideloading of a malicious libcef.dll. The adware's advertising function does not work. Attacke…
Elastic Security Labs is tracking REF8801, a campaign in which a fake Web3 venture capital accelerator, Apex Accelerator (Apex Foundation), targets cryptocurrency startups and founders with malicious npm packages. The packages, @apexacc/cli and @apexacc/audit, pose as an AI advisor and an MCP-based security scanner, with offers of free Cl…
Kaspersky researchers describe a new MacSync macOS infostealer variant, first seen in the wild in September 2026, that replaces the earlier AppleScript-based droppers with FAT Mach-O binaries written in Objective-C and Swift. MacSync is sold as malware-as-a-service, so delivery varies by operator. In this campaign it spread through malici…
