streak-view-core@1.0.0

Summary

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.
