- @akunsansan0/teaguntur99Malicious npm package containing autopublish scripts
@akunsansan0/teaguntur99 is a malicious npm package identified as part of the tea.xyz token reward campaign that flooded npm with fraudulent packages. The package contains autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) designed to automatically generate and publish derivative packages with randomized names.
The malicious payload modifies package.json to remove private flags and changes version numbers, then generates random Indonesian-themed and English-themed package names. The scripts continuously republish variants to pollute the npm registry and artificially inflate developer reputation scores for tea protocol token rewards.
This incident was identified by Amazon Inspector and credited to the OpenSSF malicious-packages repository. The attack represents a systematic attempt to manipulate the npm ecosystem for financial gain through token reward schemes.
