Summary
Malicious code in streak-int-lib (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (0acd9bdc8d6474a54b3c985b8472cd50295130d12029de1a8a10175f9be8bb35)

streak-int-lib@1.0.0 ships an x86-64 ELF binary as a base64 blob disguised as configuration data (defaultConfig.data joined into embeddedService in index.mjs). On module import, top-level code invokes initializeBackgroundService(), which decodes the blob, writes it to ~/.config/systemd/user/index with mode 0755, and spawns it via child_process.spawn with detached:true, stdio ignored, and proc.unref() so the native process outlives Node. The decoded binary contains TLS/networking symbols (SSL_write, SSL_connect, TLS_client_method, getaddrinfo, gethostname, setsid), indicating a network-capable backgrounded payload. Cover-story comments describe the side effect as a benign 'startup self-check' that 'touches no network and no filesystem', contradicting the observed behavior. The package's declared calendar-math purpose has no need for a bundled ELF or a systemd-path persistence artifact.

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.
