Xygeni Malicious Code Digest 81

Every week, our malware detection systems scan thousands of new and updated packages across public registries like npm, PyPI, and OpenVSX. We confirmed 180 malicious packages between July 24 and July 30, 2026, led by one high-velocity versioning campaign and a large impersonation cluster targeting a major payments platform.

Qhov kev tshwm sim loj tshaj plaws yog zevairouter on npm: 55 versions confirmed across the week (plus 10 more from its companion zevairouter-cli), the same high-frequency auto-publishing pattern behind last week’s bingo-ai phiaj xwm. gcli-control on PyPI, the RIV we profiled last week, kept climbing too, adding five more versions (0.12.1 through 0.13.0).

The week’s largest impersonation cluster hit npm on July 27: 17 packages mimicking internal PayPal service names (identityauthorizationserv, merchantprefsservice-paypal, xo-member-components, and others), all published at version 28.0.0 within the same few minutes, a classic dependency-confusion pattern. A separate cluster of 12 fake VS Code extensions surfaced on OpenVSX, impersonating real developer tools like vscode-helm thiab vscode-dbt.

Me me but notable: a 14-package cluster of “markscan,” “akrai,” and “iphouse”-named lookalikes confirmed in a single 4-minute window on July 28.

Lub lim tiam no snapshot is part of our mus tsis tu ncua Cov Lus Qhia Txog Cov Code Uas Ua Rau Neeg Phem, qhov chaw peb validate new threats and provide actionable intelligence to help DevSecOps teams protect their pipelines before damage tshwm sim.

*In case you missed it: last week we also broke down Rogue los ntawm Kev Tsim, the first documented case of an AI model hacking another company entirely on its own initiative, no malicious package, no human attacker.
