  "description": "<h3>Executive Summary</h3>\nRasoon is a specialized Information Stealer (Info-Stealer) and Trojan designed to covertly infiltrate Windows systems and extract sensitive authentication data. It primarily focuses on harvesting credentials saved within web browsers, email clients, and FTP software, transmitting this stolen data back to an attacker-controlled command-and-control (C2) server for monetization or further exploitation.\n\n<h3>Infection Vector and Technical Capabilities</h3>\nRasoon is typically distributed via malicious email attachments (often masquerading as invoices or shipping documents) or bundled within cracked software available on untrustworthy software portals.\n\nUpon execution, Rasoon initiates a rapid, localized search for high-value credentials:\n<ul>\n<li><strong>Browser and Email Harvesting:</strong> The malware actively scans the registry and local AppData folders to extract saved passwords, autofill data, and session cookies from major web browsers (Chrome, Firefox, Internet Explorer). It also targets email clients (Outlook, Thunderbird).</li>\n<li><strong>FTP/Webmaster Targeting:</strong> Rasoon frequently hunts for configuration files and saved passwords associated with popular FTP clients (like FileZilla or WinSCP). Stolen FTP credentials allow the attacker to deface websites or host further malware payloads.</li>\n<li><strong>Data Exfiltration:</strong> Once the data is harvested, Rasoon encrypts the stolen information and transmits it to an attacker-controlled server via HTTP POST requests, completing its execution quickly to evade prolonged detection.</li>\n</ul>\n\n<h3>Threat Assessment</h3>\nA Rasoon infection poses a severe risk to an organization's internal and external infrastructure. The theft of session cookies can bypass Multi-Factor Authentication (MFA), allowing attackers immediate access to corporate web applications (like O365 or Google Workspace).\n\n<h3>Incident Response and Remediation</h3>\n<ul>\n<li><strong>MFA Token Revocation:</strong> Assume session cookies were stolen. Force an immediate sign-out of all active sessions for critical web applications to invalidate the stolen tokens.</li>\n<li><strong>Local Password Reset:</strong> All user credentials saved in the affected endpoint's web browsers, email clients, and FTP software must be considered compromised and reset from a clean device.</li>\n<li><strong>Endpoint Eradication:</strong> The malware itself is typically not heavily obfuscated and can often be removed by a reputable EDR or enterprise antivirus solution. Ensure a full system scan is completed to verify eradication.</li>\n</ul>",
