Researchers Use Windows Minifilter Drivers to Detect Ransomware in Real Time

A security researcher has developed a proof-of-concept tool called Sanctum, available on GitHub, aimed at combating ransomware within the Windows operating system. Sanctum utilizes a Windows feature known as a "filter driver" to monitor file operations at a strategic chokepoint between applications and the hard drive. It employs two primary callbacks: IRPMJCREATE, which detects rapid file write or delete requests indicative of ransomware activity, and IRPMJSET_INFORMATION, which identifies changes in file metadata, such as renaming with malicious extensions. Upon detecting suspicious activity, Sanctum blocks the action and identifies the source of the threat, logging events for security teams. Future enhancements may include real-time encryption detection and the ability to freeze malicious threads. This kernel-level approach offers greater visibility and speed compared to traditional antivirus solutions.

Swarmer Tool Evading EDR With a Stealthy Modification on Windows Registry for Persistence

Praetorian Inc. has launched Swarmer, a tool that enables low-privilege attackers to maintain stealthy persistence in the Windows registry while avoiding detection by Endpoint Detection and Response (EDR) systems. Swarmer uses mandatory user profiles and the Offline Registry API to modify the NTUSER hive without triggering standard registry hooks. It operates by creating an NTUSER.MAN file that replaces the NTUSER.DAT hive upon user login, allowing low-privilege users to manipulate registry settings without alerting EDR tools. Swarmer employs functions from Microsoft’s Offline Registry Library, enabling it to perform operations without invoking Reg* API calls, thus evading detection mechanisms. Swarmer's workflow involves exporting the HKCU registry, modifying it, and executing the tool with specific commands to place the modified NTUSER.MAN file into the user profile. It can be used as an executable or a PowerShell module. While it presents a novel method for persistence, Swarmer has limitations, such as being unable to update without admin access and requiring user login to activate. Detection strategies include monitoring for NTUSER.MAN file creation and Offreg.dll usage in non-standard processes.

3 Free Windows File Managers That Beat File Explorer

Recent evaluations of three free alternative file managers—OneCommander, Files, and FileVoyager—show that they outperform Windows File Explorer in efficiency and usability, particularly for tasks like bulk renaming and data transfer. While File Explorer has improved with features like tabs and cloud integration, it still falls short for power tasks, requiring excessive clicks and context switching. OneCommander offers a familiar interface with dual-pane layouts, tabs, and interactive navigation, excelling in seamless navigation and file operations. It maintained stable connections during large data transfers. Files is a modern, open-source option with strong cloud support and effective media handling, benefiting from community-driven updates. FileVoyager provides extensive control with dual panes and customization options, appealing to power users who prefer keyboard-driven control. All three alternatives demonstrate improved interaction efficiency and stability during complex tasks compared to File Explorer, making them viable replacements for users managing extensive media libraries or engaging in heavy bulk processes.

K7 Antivirus Flaw Lets Attackers Gain SYSTEM-Level Privileges

A security vulnerability, designated as CVE-2024-36424, has been found in K7 Ultimate Security antivirus software, allowing low-privileged users to escalate their permissions to the SYSTEM level, thus gaining full control over affected Windows devices. The flaw arises from inadequate access controls in the named pipe K7TSMngrService1, which allows limited permission programs to communicate with higher-privileged programs. Attackers can exploit this vulnerability to disable antivirus protection or execute malicious code with SYSTEM privileges. K7 Computing has released several patches to address the issue, but researchers have found ways to bypass these protections. The vulnerability affects K7 Ultimate Security version 17.0.2045 and potentially earlier versions, prompting organizations to upgrade to the latest patched version.
