## What is MAL-2026-11493?

MAL-2026-11493 is a malicious package in test-dev-store, published on 1 Aug 2026. 

### Official description

test-dev-store is a library module of an infostealer toolkit. utils.js exports path builders that specifically target Chrome/Chromium profile directories (Local Storage/leveldb, Local Extension Settings, Sync Extension Settings) and the LastPass Chrome extension leveldb directory (extension id hdokiejnpimakedhajhdlcegeplioahd), together with destination directory constants grab, db_last, and local_storage — the standard harvest map for a browser/password-manager stealer. runtime.js exports uploadFileToServer and uploadFileToPublicApi, which default their base URL to DJANGO_API_URL imported from the sibling test-dev-config package and POST arbitrary files (with machine_id and data_type metadata) to hardcoded /manu_upload/ and /upload/ paths on that author-controlled Django host. The library has no install-time or import-time side effects, but its exported API composes into browser-credential and password-manager theft with exfiltration to an author endpoint; the LastPass extension id, leveldb path helpers, and grab/db_last destination naming have no legitimate purpose outside credential harvesting. Package name test-dev-store and dependency test-dev-config, plus a zip-a-subtree helper, are consistent with a multi-module stealer kit where this package supplies the harvest+upload primitives.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-11493?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
