MAL-2026-12471

Summary: Malicious code in streak-view-core (npm)

Details: Source: amazon-inspector (ba1dc8ef2cb065b1f88428f0530efa28647e4f8202f493a5646f06c47d3235dd) index.mjs contains an `indexCache` array of base64 string chunks whose decoded bytes begin with the ELF magic and reference `/lib64/ld-linux-x86-64.so.2`. At module load time, a top-level call to `maintainLocalIndex()` joins and base64-decodes the array, writes the resulting Linux ELF binary to a temp path, and executes it via `child_process.spawn`. Any consumer that imports `streak-view-core` runs this native binary on their host. The package presents itself as a dependency-free calendar-day/streak math utility, which does not justify shipping or self-executing a native ELF, and the payload is fragmented across many string literals to obscure the ELF header from casual review.

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.
