Malicious code in new-native-tools-linux-x64-gnu (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (c713b56fdb956dbd0caaa24969878e04aba9374f65d5fcfb8139771a012ff7cc) The package's only shipped artifact is a 10 MB Linux x86_64 ELF Node addon set as `main` (tools.linux-x64-gnu.node), so it is loaded automatically on `require()`. Extracted strings from the binary contain the exact Chromium Cookies SQLite schema (`FROM cookies`, `DROP INDEX IF EXISTS cookies_unique_index`, `CREATE UNIQUE INDEX cookies_unique_index ON cookies(host_key, top_frame_site_key,...)`) and password-store log lines (`Found login for`, `failed to read:`), consistent with reading Chromium/Chrome/Chromium-derivative Cookies and Login Data stores on the installer host. The same binary embeds a full outbound HTTPS stack (rustls, hyper/ureq) with proxy-environment support (`HTTPS_PROXY`, `HTTP_PROXY`, `ALL_PROXY`) and host-fingerprinting primitives (`gethostname`, `getifaddrs`, `/etc/lsb-release`, `/dev/disk/by-id/`, CPU info, `network_adapters`), plus ZIP + zstd packaging routines suitable for bundling collected data before upload. The exfiltration destination is not present as a plain string and is reconstructed at runtime. Package name mimics the `@napi-rs/*` / `@next/swc-*` platform-binary convention; the README states only "the x86_64-unknown-linux-gnu binary for new-native-tools" and does not disclose any browser-data access or network activity. The version tag `3.1.40-browser-release-151-380-1785161758` includes a unix-epoch-like suffix consistent with automated mass-publication.
AI Analysis
Technical Summary
The malicious npm package new-native-tools-linux-x64-gnu ships a 10 MB Linux x86_64 ELF Node addon binary that is automatically loaded on require(). Analysis of embedded strings reveals it reads Chromium/Chrome cookies and login data from the host system. The binary includes a full HTTPS stack with proxy environment support and host fingerprinting capabilities, enabling it to collect and exfiltrate sensitive browser data. The exfiltration destination is obfuscated and reconstructed at runtime. The package name and versioning mimic legitimate platform binaries, likely to evade detection. No vendor advisory or patch information is available.
Potential Impact
This malicious package can compromise user privacy and security by stealthily accessing and exfiltrating sensitive browser cookies and login credentials from Chromium-based browsers on Linux hosts. This can lead to account compromise, session hijacking, and unauthorized access to user accounts and services. The presence of host fingerprinting and proxy support increases the stealth and adaptability of the exfiltration mechanism.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix or official guidance is available, avoid installing or using the affected package versions. Conduct thorough audits of installed npm packages, especially those with native binaries, and remove any suspicious or untrusted packages. Monitor for unusual network activity indicative of data exfiltration.
