     @da_667 LMFAO. It worked fine for me in Reader Mode on LibreWolf / Firefox. Here's the summary:

     EXECUTIVE SUMMARY

     Cyfirma’s threat intelligence assessment of XillenStealer identifies it as an open-source, Python-based information stealer publicly available on GitHub. The malware is designed to harvest sensitive system and user data through modular scripts that utilize native libraries and Windows functions for reconnaissance and collection. Its core capabilities include extracting host identifiers, hardware specifications, Cryptocurrency credentials, and network configurations, as well as retrieving browser-stored credentials. Additionally, it incorporates screenshot capture functionality to broaden the scope of compromised information.

     The collected data is consolidated into structured outputs, frequently archived for streamlined handling, and exhibits automated exfiltration mechanisms to external communication channels, such as a Telegram bot. CYFIRMA’s analysis highlights that the open-source availability of XillenStealer not only reduces the barrier for adversaries to adopt and customize it for malicious operations but also provides defenders with valuable insights to study its architecture for enhanced detection, mitigation, and threat-hunting strategies.
