Title: UNC6148 Exploits Patched SonicWall SMA 100 Series Devices with OVERSTEP Rootkit
Date: July 16, 2025
Category: Vulnerability / Cyber Espionage
A threat actor group, identified as UNC6148, has been found targeting fully-patched SonicWall Secure Mobile Access (SMA) 100 series appliances, as part of an operation to deploy a backdoor known as OVERSTEP. This malicious activity has been traced back to at least October 2024. The Google Threat Intelligence Group (GTIG) reports that the number of known victims is currently “limited.” The tech giant has high confidence in its assessment that the group is utilizing credentials and one-time password (OTP) seeds stolen from previous breaches, enabling them to regain access even after organizations have implemented security updates. Metadata analysis indicates that UNC6148 may have first exfiltrated these credentials from the SMA appliance as early as January 2025. The precise method of initial access for delivering the malware remains unknown due to the evasive actions taken by the threat actor.

Hackers Exploit Microsoft Teams to Distribute Enhanced Matanbuchus 3.0 Malware to Targeted Companies
July 16, 2025
Threat Intelligence / Vulnerability
Cybersecurity researchers have identified a new variant of the established malware loader Matanbuchus, which boasts enhanced stealth features to evade detection. Matanbuchus, a malware-as-a-service (MaaS) offering, serves as a launchpad for various next-stage payloads, including Cobalt Strike beacons and ransomware. Initially advertised in February 2021 on Russian-speaking cybercrime forums for a rental fee of $2,500, the malware has been utilized in ClickFix-like schemes to deceive users into visiting compromised yet legitimate sites. Over time, Matanbuchus’ delivery methods have evolved, incorporating phishing emails with malicious Google Drive links, drive-by downloads from compromised websites, harmful MSI installers, and malvertising. It has been instrumental in deploying numerous secondary payloads such as DanaBot, QakBot, and Cobalt Strike, all of which are precursors to ransomware attacks.
