Threats tagged 'session hijacking'

This analysis examines a series of coordinated SaaS account compromises across multiple customer environments, involving suspicious logins from VPS-linked infrastructure followed by unauthorized inbox rule creation and deletion of phishing-related emails. The attackers leveraged virtual private servers (VPS) from providers like Hyonix to bypass geolocation-based defenses, evade IP reputation checks, and blend into legitimate traffic. Key tactics included session hijacking, inbox rule manipulation, and attempts to modify account recovery settings. The incidents highlight the growing abuse of VPS infrastructure in stealthy, scalable attacks targeting SaaS platforms.

PupkinStealer is a newly identified .NET-based information-stealing malware that extracts sensitive data like web browser passwords and app session tokens, exfiltrating it via Telegram. It targets Chromium-based browsers, Telegram, and Discord, focusing on credential theft and session hijacking. The malware performs minimal system discovery, collects files from the desktop, and captures a screenshot. It packages stolen data into a ZIP archive and sends it to the attacker through Telegram's Bot API. PupkinStealer doesn't employ persistence mechanisms, relying on quick execution and low-profile behavior. Its primary evasion technique is leveraging legitimate Telegram infrastructure for communication.
