- abina-amugi-anupcamainpm package containing malicious autopublish scripts
The npm package abina-amugi-anupcamai was identified as containing malicious code by Amazon Inspector and credited to OpenSSF's malicious-packages repository. The package includes autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) that execute automatically upon installation.
The malicious payload modifies package.json to remove private flags and alter version numbers, then generates random package names—primarily Indonesian-themed variants, with some English-language alternatives—and continuously republishes them to the npm registry. This activity is designed to artificially inflate developer reputation metrics associated with the tea protocol token reward campaign.
The attack represents a form of registry pollution and potential supply chain compromise for any developer who installed the package or its auto-generated derivatives. The campaign appears to be part of a larger coordinated effort to flood npm with similar malicious packages.
