The npm package streak-int-lib version 1.0.0 contains a malicious embedded x86-64 ELF binary disguised as configuration data. Upon import, the package decodes this binary, writes it to a systemd user path with executable permissions, and spawns it as a detached background process. The binary includes TLS and networking functions, indicating network communication capability, contradicting the package's stated benign purpose. This behavior suggests a hidden persistent network-capable payload unrelated to the package's declared functionality.
