White Paper on TCLBanker Malware
TCLBanker is an advanced type of trojan that specifically targets 59 different banking, fintech and cryptocurrency platforms. This malware usually infiltrates systems via a trojanized MSI installer of the legitimate software 'Logitech AI Prompt Builder'. The most striking feature of the software is that it has the ability to spread itself automatically via WhatsApp and Outlook.
Infection Symptoms and Risks
After settling into the system, TCLBanker aims to steal users' financial data by working in the background. System slowdown, unexplained network traffic, and unexpected changes in browser plug-ins are among the main symptoms.
Warning: Never run suspicious MSI files with administrative privileges. Always check the digital signature of the software.

To protect against threats such as TCLBanker, it is critical to adopt the 'Zero Trust' principle. Users need to be educated, especially about e-mail attachments and files received via messaging applications. At the enterprise level, unauthorized MSI installations should be prevented by implementing application whitelisting (AppLocker) policies.
System administrators should tighten firewall rules to block suspicious traffic flows and enforce the use of multi-factor authentication (MFA), especially on endpoints where financial data is processed. Since TCLBanker manipulates the Outlook and WhatsApp APIs to propagate itself, it is vital that these applications are kept updated and plugin permissions are restricted.
