Malicious code in ts-eslinter (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (56fe794783cf855aba4980f7186b85866fd3048cbb97803fe8c575192cb30d44) Package name resembles common ESLint/TypeScript tooling and the main entry index.js contains base64 decoding via Buffer.from(..., 'base64').toString('utf8') at line 7 (with another Buffer.from at line 86). Base64 decoding of an embedded string is a common precursor to obfuscated payload execution, but it is also used for many legitimate purposes (config blobs, asset embedding, default keys). Without traced execution showing the decoded bytes being eval'd, executed via child_process, or sent over the network, intent cannot be confirmed from the available evidence. The name is also close to legitimate linter packages, which warrants a human look. ## Source: ghsa-malware (a31a70f73d25ed15fda28427e476afffbf8c8c5a617b9afb8c5d1b76d11d9154) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
AI Analysis
Technical Summary
The 'ts-eslinter' npm package version 1.0.0 is identified as malicious code that compromises the host system entirely. According to the source details, installation or execution of this package results in full system compromise, potentially allowing an attacker to gain complete control. Due to the severity of the compromise, simply uninstalling the package is insufficient to ensure system integrity, as additional malicious components may persist.
Potential Impact
Any system with 'ts-eslinter' version 1.0.0 installed or running is considered fully compromised. Attackers may have gained complete control over the system, risking exposure or theft of all stored secrets and keys. This could lead to further unauthorized access, data breaches, or persistent malicious activity.
Mitigation Recommendations
Remove the 'ts-eslinter' package version 1.0.0 immediately. Rotate all secrets and keys stored on the compromised system from a different, secure computer. Because the system is fully compromised, consider rebuilding or thoroughly cleaning the affected machine to ensure removal of all malicious software. Patch status is not applicable as this is a malicious package rather than a vulnerability with an official fix.
