What your firewall sees that your EDR doesn’t
The group known as Librarian Ghouls has infiltrated networks of technical universities and industrial organisations across Russia, Belarus and Kazakhstan, all without raising immediate alarms. They achieved this by leveraging legitimate logins to move laterally through internal networks, utilising valid credentials and avoiding alert triggers. Unlike many other APT groups, Librarian Ghouls does not rely…

New ClickFix attacks use fake Windows Update screens to fool employees
Run dialog box, Windows Terminal, or Windows PowerShell. This leads to the downloading of scripts that launch malware.Two new tactics are used in the latest ClickFix campaign, says Huntress:the use since early October of a fake blue Windows Update splash page in full-screen, displaying realistic “Working on updates” animations that eventually conclude by prompting the user to…

Every significant CVE tells a story, known exploit activity, actor interest, proof-of-concept code or links to MITRE ATT&CK techniques. This external intelligence gives us the who and how behind potential exploitation.For example, when a privilege escalation vulnerability in Linux…

SilentButDeadly: New Tool Blocks Network Traffic to Bypass EDR and Antivirus
A newly released open-source tool called SilentButDeadly is raising security concerns by demonstrating how attackers can effectively turn off Endpoint Detection and Response systems and antivirus software without terminating any processes. Developed by security researcher Ryan Framiñán and released on November 2, 2025, the tool exploits the Windows Filtering Platform to sever cloud connectivity for…

RONINGLOADER Uses Signed Drivers to Disable Microsoft Defender and Bypass EDR
Elastic Security Labs has uncovered a sophisticated campaign deploying a newly identified loader, dubbed RONINGLOADER, that weaponizes legitimately signed kernel drivers to systematically disable Microsoft Defender and evade endpoint detection and response (EDR) tools. Attributed to the Dragon Breath APT group (APT-Q-27), this campaign demonstrates a significant evolution in attack sophistication, primarily targeting Chinese-speaking users…

New Browser Security Report Reveals Emerging Threats for Enterprises
According to the new Browser Security Report 2025, security leaders are discovering that most identity, SaaS, and AI-related risks converge in a single place, the user’s browser. Yet traditional controls like DLP, EDR, and SSE still operate one layer too low.What’s emerging isn’t just a blindspot. It’s a parallel threat surface: unmanaged extensions acting like…

Alleged Russia-linked Curly COMrades exploit Windows Hyper-V to evade EDRs
Curly COMrades threat actors exploit Windows Hyper-V to hide Linux VMs, evade EDR tools, and deploy custom malware undetected. Bitdefender researchers, aided by Georgia’s CERT, uncovered that Curly COMrades, a group linked to Russian interests, abused Windows Hyper-V to gain covert, long-term access to victims. Threat actors created hidden Alpine Linux VMs (120MB/256MB) hosting custom…
