The helpers are labeled with calendar/cache-style names and JSDoc ('Ensure directory exists', 'Save data to cache', 'Start a background task') while their bodies dynamically import node:fs and node:child_process to perform the drop-and-run. The decoded ELF64 targets /lib64/ld-linux-x86-64.so.2 and imports TLS_client_method, SSL_CTX_new, SSL_connect, SSL_read, SSL_write, socket, bind, listen, getaddrinfo, gethostbyname, fork, setsid, dup2, execl, execv, and pthread_create — the shape of a TLS-based remote-shell implant that grants a remote peer command execution on the installer's host. The ELF is split into ~260-character base64 slices to defeat single-string signatures, and the README's 'tiny startup self-check, no postinstall' framing masks the import-time drop-and-execute.\n","affected":[{"package":{"ecosystem":"npm","name":"streak-map-metrics"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"dist/index.mjs","sha256":"d010a3f1797c2fb22fb7778a3a3a895f554a187b658512268fdffe2ddd9738ee","tlsh":"ec834cf29a863c87a5b19d18d64138082d6c66832178d177fec863ebb3e5250df5ecb4"},{"path":"dist/internal/daymath.mjs","sha256":"979124adb7a8ef046aabbf407bfd8f8df995ef54a8115d410824916b5e77ed74","tlsh":"3c518497ffe56338c774d260894ac58bf379e2313eaac8da904c66501a46036963dfc9"}],"package_integrity":[{"filename":"streak-map-metrics-1.0.0.tgz","hashes":{"sha1":"912f4eb9733d5d130d9636a2f25d52eb25441958","sha512_sri":"sha512-IkDtWd4PjDXP9bK7/dDrAKdwcEy32xIrhLJmfjNAE+ZjUlZ7XaaOgHg6fIm7l+lus5viUePhdZm2p4Pc5fsgjw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/streak-map-metrics/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-011372","import_time":"2026-08-05T00:04:39.960409978Z","modified_time":"2026-08-05T00:03:48Z","sha256":"fb9123af3cafc613a53d0dc4ab34b30f955cab139b961dcd1c5f106e952332c3","source":"amazon-inspector","versions":["1.0.0"]}]}}
