@akunsansan0/tehpucuk2 is a malicious npm package identified as part of a coordinated campaign to flood the npm registry with reward-seeking packages. The package contains autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) that automatically generate and republish derivative packages with randomized names, primarily Indonesian-themed but also English variants.

The malicious payload modifies package.json to remove private flags and alter version numbers, enabling continuous republication of variants to the npm registry. This behavior is designed to artificially inflate developer reputation scores for the tea protocol token reward campaign.

The incident was identified and reported by the OpenSSF's malicious-packages project (MAL-2025-181352). This represents a form of registry pollution and supply chain attack targeting the npm ecosystem's integrity and developer trust.
