Summary
Malicious code in tinyparrot (npm)
Details

Source: amazon-inspector (ec7ebbcc82edaa241764193ea85c0492b99f9ed3be805c57ef0914518cd4b6f9)

The postinstall script src/build.js reconstructs the strings 'https', 'POST', and the destination host 'rnjkerbf.org/P' from integer-encoded arrays via base-decoders in src/const.js and src/helpers.js, then dynamically requires the resolved module and issues an HTTPS POST to https://rnjkerbf.org/P. The value of the response header 'm' is passed directly to child_process.execSync, so arbitrary shell commands returned by the attacker-controlled server run on the installer's machine at 'npm install' time. Errors are swallowed by try/catch to hide failures. The URL, HTTP method, and required module name are all hidden behind numeric-literal decoders to evade static inspection.

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.
