MemTensor Supply Chain Attack Delivers Sckit Credential Stealer via npm and PyPI
In September 2026, unknown threat actors compromised legitimate MemTensor packages across npm and PyPI repositories, injecting a cross-platform Go-based credential stealer called 'sckit'. The malware targeted @memtensor/memos-cloud-openclaw-plugin versions 0.1.21, 0.1.23, and 0.1.25 on npm, and MemoryOS version 2.0.34 on PyPI. The implant harvested sensitive credentials from cloud services, source-code platforms, package registries, and developer tools, exfiltrating data to skyleen[.]fr. The attackers obtained publish tokens from MemTensor's GitHub Actions pipelines and designed the malware to self-proliferate like a worm through GitHub and direct package publishing. This incident highlights the growing sophistication of supply chain attacks targeting AI and machine learning ecosystems, where attackers increasingly exploit trusted development pipelines and package repositories to distribute credential-stealing malware at scale.
