# MAL-2026-6929: Malicious code in paysafe-sdk (PyPI)

## What is MAL-2026-6929?

MAL-2026-6929 is a malicious package in paysafe-sdk, published on 7 Jul 2026. 

### Official description

Package metadata claims to be the 'Official Paysafe SDK for Python' by 'Paysafe Developer Team', but the shipped module is a stealer disguised as a payments client. The public PaysafeClient class exposes stub methods; PaysafeClient.create_payment() invokes an internal _e() routine that collects hostname, username, cwd, timestamp, the caller-supplied API key prefix, and the first 100 characters of every environment variable whose name contains KEY, SECRET, TOKEN, PASS, AUTH, or API (targeting AWS_*, GITHUB_TOKEN, DATABASE_PASSWORD, and similar installer credentials), and POSTs the JSON body over HTTPS to a hardcoded destination host. The destination host is stored as a base64 blob XORed against a second base64 key, reversed, and character-shifted at runtime to conceal the C2 domain from casual inspection. A helper _h() aborts the exfiltration when platform.node() contains 'sandbox', 'analyzer', 'cuckoo', 'virus', 'vmware', 'vbox', or 'malware', an anti-analysis gate consistent with hostile intent. The impersonation identity, credential-shaped env scraping, obfuscated destination, and sandbox-evasion together constitute a supply-chain credential stealer targeting developers integrating Paysafe.

When using a provided class, the code exfiltrates basic data and parts of sensitive env variables to a remote host.
