A new ransomware campaign is underway, leveraging critical vulnerabilities in Fortinet's FortiOS and FortiProxy systems. The SuperBlack ransomware, deployed by the cybercriminal group Mora_001, targets Fortinet firewalls by exploiting authentication bypass flaws, specifically CVE-2024-55591 and CVE-2025-24472. Once inside, attackers escalate privileges to super-admin and create new administrator accounts, modifying automation tasks to ensure persistent access, even if initially removed.

The vulnerabilities, disclosed in January and February of 2025, allow attackers to gain unauthorized access and encrypt devices after the initial compromise, attackers map the network and attempt lateral movement using stolen VPN credentials and newly added VPN accounts. They utilize Windows Management Instrumentation (WMIC), SSH, and TACACS+/RADIUS authentication, which are protocols for managing and authenticating network access. Organizations are urged to patch their Fortinet systems to mitigate the risk of SuperBlack ransomware attacks.

Fortinet's FortiGuard Labs has issued a high-severity alert regarding the Coyote Banking Trojan. This sophisticated malware, targeting Microsoft Windows users, has expanded its reach to include 1,030 websites and 73 financial institutions. The malware is distributed through malicious LNK files that execute PowerShell commands, initiating a multi-stage attack. The primary goal is to harvest sensitive data, including system details and lists of installed antivirus products.

The attack sequence begins with a LNK file executing a PowerShell command to retrieve a next-stage PowerShell script, launching the trojan. Once deployed, the trojan gathers system information and evades detection by security measures. Should a victim attempt to access a targeted site, the malware communicates with a command-and-control server, enabling actions like capturing screenshots or displaying phishing overlays to steal sensitive credentials, impacting financial cybersecurity.

A new variant of the Snake Keylogger malware is actively targeting Windows users, with over 280 million infection attempts detected globally. Cybersecurity researchers have identified this version, also known as the 404 Keylogger, as AutoIt/Injector.GTY!tr. The primary targets include users in China, Turkey, Indonesia, Taiwan, and Spain, where the malware spreads through phishing emails containing malicious attachments or links. The keylogger steals credentials from popular web browsers like Chrome, Edge, and Firefox by logging keystrokes, capturing screenshots, and monitoring the clipboard.

The stolen data, including sensitive information and credentials, is then exfiltrated to its command-and-control (C2) server through various methods, including SMTP email and Telegram bots. The malware utilizes AutoIt, a scripting language frequently used for Windows automation, to deliver and execute its malicious payload. By using AutoIt, the malware can create standalone executables that may bypass standard antivirus solutions. Once executed, the keylogger copies itself to the %Local_AppData%\supergroup folder, names itself ageless[.]exe, and sets its attributes to hidden and creates “ageless.vbs” in the %Startup% folder.

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.

A new hacking group, known as Belsen Group, has leaked configuration files and VPN credentials for over 15,000 FortiGate firewall devices. The data, which includes full configuration dumps, device management certificates and even some plain text passwords, was made freely available on the dark web. Security researcher Kevin Beaumont first brought the issue to light, later confirmed by CloudSEK, and noted the vulnerability primarily affected Fortigate 7.0.x and 7.2.x devices.

The Belsen Group is believed to have been active since 2022, despite only recently appearing on social media and cybercrime forums. The leaked data was likely collected using a zero-day exploit in 2022, specifically CVE-2022-40684, and has only been released in January 2025. This means even organizations that have since patched may still be vulnerable if their configurations were captured by Belsen Group in 2022. The exposure of the data, which includes firewall rules, poses a significant security risk to affected organizations.
