Malicious code in strath (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (b9ae02b92920c1e028b5785e69013ea4662e4eb3180872531d64ccca00eef239) The package declares a postinstall script that runs dist/config.js. That script fetches JSON from https://my-api.trade-api.workers.dev?id=2 and then executes `globalThis[data.success](data.id)`, where both the method name and its argument are supplied by the remote server. This gives the operator of that endpoint arbitrary code execution on any machine that runs `npm install strath` — the invocation fires automatically as part of the default install lifecycle. The behavior is unrelated to the package's advertised path-utility purpose. The same script also references `globalThis[tag](text)` with undefined identifiers, consistent with a deliberately opaque dropper shape rather than a normal build step.
AI Analysis
Technical Summary
The 'strath' npm package versions 1.1.0 and 1.1.1 include a postinstall script that executes 'dist/config.js'. This script fetches JSON from a remote endpoint and dynamically invokes a global method with arguments provided by the server, enabling arbitrary code execution during installation. The script also references undefined global identifiers, consistent with a deliberately obfuscated malicious dropper rather than a legitimate build step. This results in remote-controlled code execution on any system installing these package versions.
Potential Impact
Any system that installs 'strath' versions 1.1.0 or 1.1.1 will execute code controlled by the remote server operator, leading to arbitrary code execution. This compromises the security and integrity of the affected system, potentially allowing full system compromise or further malicious activities.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid installing 'strath' versions 1.1.0 and 1.1.1. Remove these versions if already installed and consider using trusted package sources. Monitor for updates or advisories from the package maintainers or npm registry for remediation guidance.
