renderctxPyPI
Advisory published Updated
renderctx is a confirmed malicious PyPI package (MAL-2026-3207) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.0, 0.1.1, 1.1.1…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in renderctx (PyPI)
What this malware does
Packages in this campaign are used to exfiltrate data from users installing code from prepared Github repositories. Packages contain code to exfiltrate files (typically .env files, but it could also be log, txt or code files), and may also create a persistent backdoor via embedding a hardcoded SSH key or perform other actions. The malicious actions are not triggered via the code in malicious repositories pretending to be some early-stage cryptocurrency-related projects.
Based on the attribution of some NPM packages used in malicious repositories published under https://github.com/0xsebasneuron, this is likely part of North Korean actions targeting developers via fake interviews: https://socket.dev/supply-chain-attacks/north-korea-s-contagious-interview-campaign
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for renderctx (6 malicious versions).
If you installed it — respond
renderctx is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If renderctx was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks renderctx-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
