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…
The threat actor behind the GhostAction supply chain campaign has expanded beyond malicious GitHub Actions workflows.

SafeDep reports that the PolinRider loader family now resolves its C2 servers from Ethereum mainnet. The loader reads small transactions from operator wallets and decodes the recipient address as an IP:port. SafeDep confirmed 35 GitHub repositories carrying the loader at HEAD on 2026-09-30 (7,578 stars and 2,884 forks combined). The inves…
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-…
A ClickFix malvertising campaign uses sponsored Google results for "amazon business" to lure victims to a fake Amazon login page on Google Sites and then to a fake CAPTCHA. The CAPTCHA pastejacks a command into the clipboard that the victim is told to run in the Windows Run box. The command abuses the legacy finger.exe utility to fetch a …
SafeDep reports that the npm package imgdecode (versions 1.0.0-1.0.3, publisher malfexteste8) is part of the MALFEX campaign, which targets Windows developers. After npm removed earlier JavaScript loaders, the operator moved the loader logic into a compiled Node.js native addon (a Windows DLL). On require('imgdecode') from an interactive …
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…
