MAL-2026-6753: Malicious code in schemavault (PyPI)
The schemavault PyPI package versions 4.1.0 and 4.1.1 are part of a malicious campaign involving multiple interdependent packages. During installation, schemavault is used by the procwire package to execute obfuscated malicious code that downloads and runs a remote executable, likely an infostealer, which contacts a suspicious domain and then deletes itself. The malicious behavior is triggered by overriding the install command in setup.py and includes steganography to hide the malware URL. This campaign also affects other packages that depend on procwire, such as confighub, spreading the malware further.
AI Analysis
Technical Summary
The malicious campaign identified as 2026-07-procwire involves the schemavault package (versions 4.1.0 and 4.1.1) on PyPI, which is used as a dependency by procwire. Procwire overrides the installation process to execute malicious code that downloads and runs a remote executable containing an infostealer. The malware URL is hidden using steganography within an image and encoded bytes decoded by the bytekit package. The executable contacts the domain 030502[.]xyz and removes itself after execution. This campaign uses obfuscation and dependency chaining to spread malware through PyPI packages.
Potential Impact
Installation of schemavault versions 4.1.0 or 4.1.1 as a dependency of procwire or confighub leads to execution of malicious code that downloads and runs a remote infostealer executable. This compromises the affected system by potentially stealing sensitive information and executing unauthorized code. The malware uses obfuscation and steganography to evade detection and removes the executable after running, complicating forensic analysis.
Mitigation Recommendations
No official patch or remediation is currently documented for schemavault versions 4.1.0 and 4.1.1. Users should avoid installing or using these versions and any packages depending on procwire or confighub until the packages are cleaned or removed from PyPI. Verify package integrity and source before installation. Monitor PyPI advisories for updates or removal of malicious packages. Since this is not a cloud service, remediation depends on user action to avoid or remove the malicious packages.
