Rewterz Threat Alert – KLBanker Banking Trojan – Active IOCs

Severity

High

Analysis Summary

The KLBanker Banking Trojan is a type of malware that specifically targets online banking systems. It is designed to steal sensitive financial information, such as login credentials, credit card details, and other personal data, from victims’ computers.

The KLBanker Trojan is typically distributed through malicious email attachments, compromised websites, or social engineering techniques. Once it infects a system, it runs in the background and monitors the user’s online activities, specifically focusing on banking websites. It can capture keystrokes, take screenshots, and intercept network traffic to gather sensitive information.

The stolen information is then sent to a remote server controlled by the attackers. They can use this data to gain unauthorized access to the victim’s bank accounts or carry out fraudulent transactions. The KLBanker Trojan is often capable of bypassing two-factor authentication and other security measures implemented by banks, making it even more dangerous.
