Hackers Deploy Casbaneiro Banking Trojan That Activates When Victims Open Bank Websites
AI summary · glm-5.3Summaries by Vani AI
Fortinet details Casbaneiro banking Trojan campaign hitting Latin American bank customers via invoice-themed PDF phishing, with AutoIt loading, RegSvcs.exe injection, and bank-site-triggered activation.
Fortinet identified an August 2026 Casbaneiro banking Trojan campaign targeting users in Argentina, Peru, Colombia, and Mexico through phishing PDFs styled as urgent invoices or legal notices. The staged chain uses IP-based geo-filtering, a Base64-encoded ZIP, an HTA file, and a legitimate AutoIt interpreter before injecting into RegSvcs.exe or mobsync.exe and persisting via a Startup shortcut. The Trojan exfiltrates address book and Outlook data unencrypted, stays dormant until victims visit targeted bank sites, then accepts commands for keyboard control, clipboard pasting, file execution, and command execution. It uses an expected HTTP 403 response from a second server and malformed HTTP requests to complicate network analysis.
Key facts
- Phishing PDFs posing as invoices and legal notices target bank users in Argentina, Peru, Colombia, Mexico.
- Geo-filtering redirects non-target IPs to Google or YouTube to evade researchers.
- AutoIt loader injects into RegSvcs.exe/mobsync.exe and persists via Startup shortcut.
- Activates only on targeted bank sites, enabling keyboard, clipboard, and command control.
- Expected HTTP 403 responses and malformed requests complicate network analysis.
