A new backdoor, dubbed A0Backdoor, has been discovered in connection with a campaign using email bombing and IT-support impersonation over Microsoft Teams to gain Quick Assist access. The malware's loader exhibits anti-sandbox evasion techniques, and the campaign's command-and-control has shifted to a covert DNS mail exchange-based channel. This activity is attributed to the threat group Blitz Brigantine, also known as Storm-1811 or STAC5777, and shows similarities to Black Basta-linked social-engineering tactics. The attackers use digitally signed MSI packages, often hosted on Microsoft cloud storage, to deliver their proprietary tooling. The A0Backdoor employs sophisticated techniques such as time-based execution windows, runtime decryption, and DNS tunneling for covert communication. The campaign has been active since August 2025, targeting primarily the finance and health sectors.
An intrusion attributed to MuddyWater, an Iranian-linked APT, was identified in a customer environment. The attack involved initial access through RDP, establishing an SSH tunnel, and deploying malware via DLL side-loading. The threat actor used FMAPP.exe, a legitimate Fortemedia Inc.application, to load a malicious FMAPP.dll for C2 communications. The timeline of activities revealed typos in commands, suggesting manual typing by the attacker. The intrusion included reconnaissance efforts, attempts to verify tunnel functionality, and issues with initial C2 communication. The attack targeted an Israeli company, aligning with known MuddyWater tactics.

The ongoing conflict in the Middle East has triggered a surge in cybercriminal activity. Over 8,000 newly registered domains with conflict-related keywords have been identified, many of which may be weaponized in future campaigns. Multiple cases of malicious activity have been observed, including targeted attacks using conflict-themed lures, deployment of the LOTUSLITE backdoor, fake news blogs leading to StealC malware, phishing sites impersonating government portals, donation scams, fraudulent storefronts, and meme-coin pump-and-dump schemes. Threat actors are leveraging various techniques such as DLL sideloading, shellcode execution, and social engineering to compromise victims. The campaigns demonstrate the opportunistic nature of cybercriminals in exploiting geopolitical events for malicious purposes.

A campaign using fake Zoom and Google Meet pages to lure victims into fraudulent video calls has been identified. The attackers use these pages to deliver remote-access software. Multiple domains hosting identical fake meeting pages were discovered, with one domain previously linked to a ClickFix campaign. The fake interfaces show an active meeting with expected participants. When victims join, they are prompted to download a file disguised as a Zoom update. Various payloads were identified, including executables masquerading as meeting updates, MSI installers deploying legitimate remote support software, and commercial monitoring software configured for covert remote access. The campaign's goal appears to be establishing remote access using whichever tool is most effective.

An investigation has uncovered malicious Chromium-based browser extensions masquerading as legitimate AI assistant tools to collect Large Language Model (LLM) chat histories and browsing data. These extensions have been installed approximately 900,000 times, affecting over 20,000 enterprise tenants. The malicious extensions collect full URLs and AI chat content from platforms like ChatGPT and DeepSeek, potentially exposing organizations to leaks of confidential information. The attack chain involves reconnaissance, weaponization, delivery through trusted app stores, exploitation of user trust, installation for persistence, and regular data exfiltration to attacker-controlled infrastructure. This activity transforms a seemingly benign productivity tool into a persistent data collection mechanism embedded in daily enterprise browser usage.
