Malicious code in @zaka13/thing (npm)
@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. --- _-= Per source details.

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.
