@zaka13/thingnpm

Malicious code in @zaka13/thing (npm)
What this malware does
@zaka13/[email protected] 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.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @zaka13/thing (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @zaka13/thing across your stack and pipelines.
If you installed it — respond
Remove @zaka13/thing from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @zaka13/thing was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @zaka13/thing before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
