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.

GuLoader Leverages Polymorphic Malware and Trusted Cloud Infrastructure to Evade Detection

GuLoader, also known as CloudEye, is a downloader malware that has been active since late 2019, primarily used to fetch and install secondary malware like Remote Access Trojans (RATs) and information stealers. It employs legitimate cloud services such as Google Drive and Microsoft OneDrive to host its malicious payloads, allowing it to evade detection by security tools. GuLoader utilizes advanced techniques including polymorphic code, which alters its appearance to avoid static detection signatures, and exception-based control flow to confuse analysis tools. Over the years, GuLoader has refined its tactics, including the use of software breakpoints and various exception types to redirect its operations. It also employs dynamic XOR encryption to obfuscate internal data, making it difficult for analysts to extract URLs. The malware's continuous evolution poses ongoing challenges for security researchers. Indicators of Compromise (IOCs) include specific hash values for different versions of GuLoader from 2022 to 2024.

Why Should Small Businesses Invest In Antivirus Protection?

53% of UK businesses experience cybercrime attempts at least once a month, and 70% of business owners anticipate a cyber attack in the near future, yet only 35% feel adequately prepared. 43% of cyberattacks are directed at small businesses, with over half potentially closing due to the damage. Antivirus software is a cost-effective solution that can prevent data breaches, reduce the likelihood of ransomware, and protect devices of remote workers.

Your Android phone feeling slow? My 4-step refresh routine works wonders every time

To enhance the performance of an aging Android device without rooting, follow these steps: 1. Delete unused apps by navigating to Settings > Storage > Apps. 2. Clear additional storage by offloading photos to an external drive or cloud storage and clearing app cache via Settings > Storage > App > Clear Cache. 3. Check for updates by going to Settings > General > System Update and updating apps through the Google Play Store. 4. Adjust animation speed by enabling Developer options (Settings > About phone > Tap on Software information > Tap Build number seven times) and modifying the Window animation scale to 0.5x, along with Transition animation scale and Animator duration scale for improved responsiveness.

Nothing’s Playground lets you build the apps you need without coding — and it’s exactly what I need

Nothing's Playground tool allows users to create simple Android apps using AI without coding expertise. It generates mini apps based on user-defined text prompts in minutes. Currently in beta, it is exclusive to the Nothing Phone 3, with plans for broader availability in the future. Users can create, update, and revert apps, and the current version requests only three permissions: location, calendar, and contacts. A February update will add support for activity recognition, sensor data, and a Weather API, with plans for custom app icons, audio, and fonts. Access to the tool is available through the Nothing Playground website.

Your Windows PC has a secretly useful backup tool – here’s how to access it

Windows Backup is a built-in feature in Windows that allows users to back up specific folders and files, as well as create a complete system image. Backups can be directed to various media, including CDs, DVDs, external hard drives, or network locations, and users can schedule backups to run at regular intervals. However, Windows Backup has been deprecated by Microsoft and is no longer supported or updated, which may lead to occasional issues. A newer tool also named Windows Backup exists, designed for backing up and restoring specific files and settings for PC transitions. Users should prepare their storage media, typically external drives with 16GB to 32GB of space, before using the older Windows Backup. Restoration options include returning files to their original location or a different one, depending on the situation. Despite its deprecated status, Windows Backup remains functional and is considered a valuable tool for users seeking a built-in backup solution.
