Malicious code in new-native-tools-linux-x64-gnu (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (b38b165a8872e9c65dab5b230d8a4cc26e045f5fc3fd8502fd711652913af44a) The package ships a single ~10 MB Rust-compiled Linux x86_64 N-API native module (tools.linux-x64-gnu.node) referenced by `main`, with a two-line README that describes it only as a platform binary and no source. The binary embeds Chromium browser-secret extraction primitives — the Chromium `cookies` table schema (host_key, top_frame_site_key, has_cross_site_ancestor, unique-index DDL) and the Chrome Login Data password-store fingerprint (`Found login for`), plus SQLite/SQLCipher symbols including `SQLITE_AUTH_USER` — the components required to read Chrome/Chromium Cookies and Login Data stores on the host that loads the module. The same binary embeds a full HTTPS client (hyper, ureq, TLS 1.2/1.3 handshake constants, HTTP/2 framing) with proxy-environment awareness (`HTTPS_PROXY`, `ALL_PROXY`) and host-fingerprinting reads (`/etc/lsb-release`, `/dev/disk/by-id/`, `bogomips per cpu`, `CPU implementer`, `network_adapters`, `gethostname`) — the transport layer and host-identification data for exfiltration. The version tag `3.1.40-chrom-553-fix-undeletable-import-cookies-355-1784226602` labels the actual capability (Chromium cookie import) while the package name and README hide it behind a generic "native-tools" cover story. The exfil destination is assembled at runtime rather than appearing as a static literal, consistent with obfuscation of C2. Loading this module via `require()` exposes the installer's browser cookies and saved passwords to an attacker-controlled destination.
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.
