- **Confidence:** 100.0%

Package impersonates crypto-js: name is \`js-digest\` but \`package.json\` carries crypto-js's exact description ("JavaScript library of cryptography standards."), homepage \`http://github.com/brix/js-digest\` (brix is the crypto-js org), and author "Evan Vosberg" (the crypto-js maintainer). \`package.json\` declares \`"preinstall": "./lib/install-deps.mjs"\`, but \`lib/install-deps.mjs\` is not JavaScript — it is a 3.2 MB Linux x86\_64 ELF binary (magic \`7F 45 4C 46\`, sha256 \`7883bda1ff15425f2dbe622c45a3ae105ddfa6175009bbf0b0cad9bf5c79b316\`). On \`npm install\`, npm's preinstall hook executes this native binary with the installer's privileges before any code is reviewed. Strings extracted from the binary show a multi-platform credential harvester: HTTP requests scraping GitHub (\`GET /user\`, \`/user/repos\` with \`Authorization: Bearer...\`), Slack (\`POST /api/auth.test\` with \`Cookie: d=\`), Discord, Microsoft Teams (\`/api/mt/\*\`), and HashiCorp Vault (\`X-Vault-Token\`, \`/v1/...\`); reads of \`/.vault-token\`, \`/.vault/token\`, \`gpg --batch --no-tty --list-keys\`, and \`/proc/\<pid\>/{mem,cmdline,environ}\`; and multipart POST uploads to remote endpoints. The binary also embeds systemd unit templates (\`\[Unit\]/\[Service\]/ExecStart=.../Restart=always\`) for both system (\`/etc/systemd/system/\`) and user (\`~/.config/systemd/user/\`) scopes for persistence, plus libbpf rootkit primitives (\`bpf\_object\_\_open\_mem\`, \`bpf\_map\_\_pin\`, \`bpf\_program\_\_attach\`, maps \`hidden\_pids\`/\`hidden\_inodes\`/\`hidden\_names\`, \`/sys/fs/bpf/\`) for kernel-level concealment from \`ps\`/\`ls\`/\`lsof\`. Installing this package compromises the host with a persistent, hidden credential stealer.
