Source: amazon-inspector (a707525e88d0f5d3004f833b17a7544655da43715d9d7af3e6d635ff3a6801a9)

streak-metricsa@1.0.0 presents itself as a calendar-day math helper but its main entry (dist/index.mjs, the default exports target) embeds a Linux x86-64 ELF binary as a base64-chunk array assigned to a variable named _. At module top level — reached on any import/require of the package — the chunks are joined via Buffer.concat and Buffer.from(b,'base64'), written to disk, chmod'd 0o755, and executed via node:child_process. The dropped ELF's dynamic symbols include SSL_connect / SSL_read / SSL_write / TLS_client_method, socket / getaddrinfo, dlopen / dlsym, popen, execl / execv, fork, pthread_create, kill, and mkdtemp — the shape of a TLS-based remote-command implant. The README describes the top-level behavior as a tiny startup self-check, which does not match a native binary drop-and-execute. Any consumer that imports streak-metricsa gains an executing native implant on the host with outbound TLS and shell-exec capability.
