MAL-2026-10076 Malicious code in ts-eslint-jest (npm)

The package [email protected] presents as a TypeScript/ESLint/Jest helper but ships lib/collect.js, which imports child_process and invokes execSync('bash…') at line 205 and execSync('zsh…') at line 221. This code shape — spawning interactive shells from a purported linting/testing helper — is inconsistent with the package's declared purpose and matches the shell-history / environment harvesting fingerprint used to collect credentials, tokens, and connection strings from a developer's shell state. The name is also a lookalike of legitimate TypeScript/ESLint/Jest tooling, which supports a lure/typosquat framing. Automated tracing of collect.js was blocked by the provider's malware-content filter, which corroborates that the traced code reads as operational credential-harvesting logic rather than benign build/lint helpers.

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.
