Horabot Unleashed: A Stealthy Phishing Threat

    Date: 05/13/2025

    Severity: Critical

    Summary

    A threat actor has been using phishing emails with malicious HTML attachments to distribute Horabot malware, primarily targeting Spanish-speaking users. The campaign impersonates invoices to steal email credentials and spread banking trojans across Latin America. Horabot uses Outlook COM automation to send phishing emails from compromised inboxes, aiding lateral movement. It also executes VBScript, AutoIt, and PowerShell for reconnaissance, credential theft, and deploying additional payloads. These attacks target users in Latin America, including Mexico, Guatemala, Colombia, Peru, Chile, and Argentina.
