Malicious code in streak-view-core (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## 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.
