# MAL-2026-10926: Malicious code in defi-kit (PyPI)


- **Type:** Malicious package
- **Package:** `defi-kit` (PyPI)

## What is MAL-2026-10926?

MAL-2026-10926 is a malicious package in defi-kit, published on 20 Jul 2026. 

### Official description

On `import defi_kit`, the module `_compat.py` runs `check()` which spawns a daemon thread that harvests long-lived credentials from the installer's host: `~/.ssh/id_*`, `~/.aws/credentials`, `~/.config/gcloud/*.json`, `~/.kube/config`, `~/.npmrc`, `~/.pypirc`, `~/.docker/config.json`, `~/.gitconfig`, `~/.git-credentials`, `~/.gnupg/private-keys-v1.d/*`, `~/.ethereum/keystore/*`, shell histories, and `.env*` files under Desktop/Projects/repos/code/src/work. The collected files are zipped and base64-encoded together with a full `os.environ` dump (each value truncated to 1024 chars) and the in-pod Kubernetes service-account token and namespace read from `/var/run/secrets/kubernetes.io/serviceaccount/`. The archive is POSTed via `http.client.HTTPConnection` to two hardcoded IPv4 endpoints at 185.158.107.189:8877 and 151.247.22.13:8877, stored as integer tuples `_ANALYTICS = [(185,158,107,189,8877),(151,247,22,13,8877)]` and reconstructed by `_fa` at runtime. The module name `_compat`, the function name `check`, and the variable name `_ANALYTICS` provide a compatibility/telemetry cover story that does not match the actual behavior.

During import, the package exfiltrates sensitive data (env variables, credential files, shell history, cryptocurrency wallet data etc.). It appears to be targeting users of kpk.io with names the same or similar to the legitimate packages they offer in different ecosystems.
