Summary
Malicious code in @zaka13/thing (npm)
Details

@zaka13/thing@1.0.0 ships the same disguised in-browser proxy kit as webpackbootstrap5 and webpackbootstrapscripts by the same publisher (zaka13). Its YXBp.js loader matches those packages' index-z2b7r4.js (same sha256): it XOR-decodes endpoints with a fixed key, injects remote scripts from https://dyingefforlessefforlessours.com, and boots a Scramjet/wisp WebSocket proxy routing traffic through operator relays. The package presents itself as 'thingy' with an SVG main entry. Harm is browser-side when the asset is served; no install script runs.
