Kaspersky discovers Ghimob banking malware targets mobile users worldwide – Back End News

Protect yourself from online attacks that threaten your identity, your files, your system, and your financial well-being.


When monitoring a Windows campaign from Guildma banking malware, Kaspersky researchers found URLs distributing not only a malicious .ZIP file for Windows, but also a malicious file that appeared to be a downloader to install Ghimob, a new banking Trojan.

Upon infiltrating Accessibility Mode, Ghimob can gain persistence and disable manual uninstallation, capture data, manipulate screen content, and provide full remote control to the actors behind it. According to experts, the developers of this “very typical” mobile Remote Access Trojan (RAT) are heavily focused on users in Brazil but have big plans to expand across the globe. The campaign is still active.

In fact, Ghimob is the first Brazilian mobile banking Trojan ready for international expansion.”

The email also includes a link for the victim to click on so they can find out more information. Once the RAT is installed, the malware sends a message about the successful infection to its server. The message includes the phone model, whether it has lock screen security, and a list of all installed apps that the malware can target. In total, Ghimob can spy on 153 mobile apps, mainly from banks, fintech companies, cryptocurrencies, and exchanges.
