AI + crypto news broke on September 24, 2026, as SlowMist reported a supply chain attack on MemTensor’s AI memory toolchain. Malicious code was embedded in PyPI version 2.0.34 of MemoryOS and npm versions 0.1.21, 0.1.23, and 0.1.25 of memtensor/memos-cloud-openclaw-plugin. The compromised packages execute cross-platform Go binaries, enabling attackers to steal credentials and exfiltrate data. Users are advised to uninstall or downgrade to secure versions, terminate sckit processes, and rotate credentials. On-chain developments highlight the growing risks in AI-powered infrastructure.

HuoXing Finance reports that on September 24, SlowMist issued a warning stating that MemTensor’s AI long-term memory toolchain has been compromised by a supply chain attack. The affected components are the open-source library MemoryOS (PyPI version 2.0.34) designed for LLMs/Agents, and the official plugin memtensor/memos-cloud-openclaw-plugin (npm versions 0.1.21, 0.1.23, 0.1.25) connecting to the OpenClaw runtime. These versions contain cross-platform Go binaries that execute upon import or when the OpenClaw gateway is launched. Attackers can steal developer credentials including npm/PyPI tokens, GitHub/GitLab credentials, AWS keys, SSH keys, API tokens, and environment variables, and exfiltrate the data; the npm plugin may also leak user prompts. SlowMist recommends users immediately uninstall or revert to known secure versions (npm 0.1.20, PyPI 2.0.33), terminate related sckit processes, block associated infrastructure, investigate network activity, and rotate all credentials in affected environments.
