Multiple suspected Russia-linked threat actors are "aggressively" targeting individuals and organizations with ties to Ukraine and human rights with an aim to gain unauthorized access to Microsoft 365 accounts since early March 2025. The highly targeted social engineering operations, per Volexity, are a shift from previously documented attacks that leveraged a technique known as device code phishing to achieve the same goals, indicating that indicating that the Russian adversaries behind these campaigns are actively refining their tradecraft to fly under the radar. "These recently observed attacks rely heavily on one-on-one interaction with a target, as the threat actor must both convince them to click a link and send back a Microsoft-generated code," security researchers Charlie Gardner, Josh Duke, Matthew Meltzer, Sean Koessel, Steven Adair, and Tom Lancaster said in an exhaustive analysis. At least two different threat clusters tracked as UTA0352 and UTA03...

A large-scale malware campaign has been found leveraging a vulnerable Windows driver associated with Adlice's product suite to sidestep detection efforts and deliver the Gh0st RAT malware . "To further evade detection, the attackers deliberately generated multiple variants (with different hashes) of the 2.0.2 driver by modifying specific PE parts while keeping the signature valid," Check Point said in a new report published Monday. The cybersecurity company said the malicious activity involved thousands of first-stage malicious samples that are used to deploy a program capable of terminating endpoint detection and response (EDR) software by means of what's called a bring your own vulnerable driver ( BYOVD ) attack. As many as 2,500 distinct variants of the legacy version 2.0.2 of the vulnerable RogueKiller Antirootkit Driver, truesight.sys, have been identified on the VirusTotal platform, although the number is believed to be likely higher. The EDR-killer module...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
