A new Android banking trojan called Crocodilus has been discovered, targeting users in Spain and Turkey. Cybersecurity experts warn that this sophisticated malware employs advanced techniques like remote control, black screen overlays, and data harvesting through accessibility logging. Crocodilus is designed to facilitate device takeover and conduct fraudulent transactions, masquerading as Google Chrome to bypass Android 13+ restrictions.

Once installed, Crocodilus requests access to Android's accessibility services and connects to a remote server for instructions and a list of targeted financial applications. The malware steals banking and crypto credentials by displaying HTML overlays and monitors all accessibility events to capture screen contents, including Google Authenticator details. Crocodilus conceals malicious activities using a black screen overlay and muting sounds to avoid detection.

The Coyote Banking Trojan is actively targeting financial institutions and online banking users in Brazil, stealing data from over 70 financial applications and websites. Cybersecurity researchers at FortiGuard Labs have uncovered this stealthy and highly sophisticated banking trojan which leverages malicious LNK files and PowerShell scripts to infiltrate Windows systems, deploy payloads, and steal sensitive banking credentials. The attack begins with a weaponized LNK file that executes a hidden PowerShell command, connecting to a remote server and downloading additional malicious scripts, initiating the next stage of the attack.

The Trojan can keylog user activity, capture screenshots, display phishing overlays, and even manipulate browser windows to steal financial data. It collects system information such as the machine ID, MAC address, Windows version, and installed security software, sending these details to remote command-and-control servers. The final payload includes the main Coyote Banking Trojan, which expands its target list to over 1,000 websites and 73 financial agents. Accessing any of the targeted sites could trigger further malicious activity, enhancing the threat to financial cybersecurity.
