statist-browser-typed-client-mb.reliability.android.metricsnpm
statist-browser-typed-client-mb.reliability.android.metrics is a confirmed malicious npm package (MAL-2026-12449) that executes malicious code on install (malicious version 20.9.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in statist-browser-typed-client-mb.reliability.android.metrics (npm)
What this malware does
On require() of the package, index.js loads loader.js which downloads a platform-specific binary from hardcoded Cloudflare Workers hosts assembled by string-array joins (oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev), with a base64-chunked DNS-TXT covert-channel fallback via *.dl.well1.site. The fetched bytes are written to /tmp or %TEMP% under disguised filenames (dotnet_diag<rand>.exe,.cache_<rand>), chmodded 0o755, and spawned detached via cmd.exe or /bin/sh. Destination hostnames are fragmented across string arrays and joined at runtime to defeat static string matching, and an environment-variable opt-out check is used to evade sandboxes. The package advertises itself as a telemetry exporter but ships a fetch-and-execute dropper reachable on import.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for statist-browser-typed-client-mb.reliability.android.metrics (version 20.9.3). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging statist-browser-typed-client-mb.reliability.android.metrics across your stack and pipelines.
If you installed it — respond
Remove statist-browser-typed-client-mb.reliability.android.metrics from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If statist-browser-typed-client-mb.reliability.android.metrics was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks statist-browser-typed-client-mb.reliability.android.metrics before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
