MALICIOUS (1) package from Python Package Index.

  1. The campaign has clearly malicious intent, like infostealers.

solanakit

Affected versions: (1) 1.0.0, 1.0.1

  1. Version numbers are usually added automatically. In most cases, the packages listed here were created only to distribute malicious code.

During import, the code downloads and starts a malicious package hosted on GitHub. It then first ensures persistency e.g., through the autostart registry key. Then, based on the encrypted config, an exfiltration demon is started. It registeres the instance in the C2 server and starts searching the file system looking for files matching given filename patterns and then monitoring changes. Discovered files are exfiltrated to hardcoded remote target. The PyPI packages are used as dependencies in newly-created crypto-related repositories on GitHub.

Campaign data

Campaign information may not always be 100% accurate for every related package.

Campaign description

The campaign is built from a benign-like package (e.g. genosys) and the malicious dependency (e.g. pynosist). The dependency uses a PTH file to trigger malicious action upon Python start. First, it ensures persistency e.g., through the autostart registry key. Then, based on the encrypted config, an exfiltration demon is started. It registeres the instance in the C2 server and starts searching the file system looking for files matching given filename patterns and then monitoring changes. Discovered files are exfiltrated to hardcoded remote target. In pynosist, the embeded configuration looks for *pemasukan*,*pengeluaran* and during analysis further updates from C2 changed patterns to "*privatekey*", "*privatekeys*", "*phrase*", "*private_key*", "*private-key*", "*airdrop*", "*private_keys*". The communication with C2 is secured by an embedded certificate.

The PyPI packages are used as dependencies in newly-created crypto-related repositories on GitHub.

See more details on the campaign page.

files_exfiltration

obfuscation

peristence_autorun
