6 Windows hardening steps that don’t break gaming or DRM

Windows 11 is not the most secure operating system by default but offers ways to enhance security without affecting gaming performance. Gaming PCs are vulnerable to cyber threats and should adopt security measures. Customizing Windows Firewall allows users to maintain internet access for gaming applications while ensuring security. Users should add key game executable files to the "allowed apps" list and consider using SimpleWall for better control over network activity. Using a standard account for gaming sessions enhances security by limiting admin account access, which should be reserved for software installation and updates. Implementing multi-factor authentication for both admin and standard user accounts adds an extra layer of security. Windows Defender has improved and can be an efficient antivirus option, but third-party solutions may conflict with gaming performance. Game files should be added to Windows Defender's exclusion list to avoid performance issues. Disabling unnecessary Windows services can enhance security and performance by reducing the attack surface and freeing up resources. Common services to disable include Cellular Time, Connected Devices Platform Service, and Telemetry. Secure Boot protects against malicious software during the boot process and may require BIOS adjustments. It does not affect gaming performance and is often necessary for games with kernel-level anti-cheat systems. Memory Integrity and Core Isolation are advanced security features that protect against low-level attacks by creating an isolated environment for critical processes. These features require minimal resources if the CPU supports Intel's Mode-Based Execution Control (MBEC) or AMD's Guest Mode Execution Trap (GMET). Balancing security measures with optimal system performance is essential for a secure gaming experience.

Is end of service leaving your system vulnerable? The risks no IT leader can ignore

Unsupported operating systems and device software lack regular updates, making them vulnerable to cyber attacks. Devices running on unsupported platforms can become gateways for attackers, as they are susceptible to known exploits that can be easily weaponized. According to Microsoft’s 2024 Digital Defense Report, over 90% of successful ransomware attacks target unmanaged endpoints. Unsupported versions can bypass standard security solutions and often fail compatibility checks with modern security tools, leading to significant protection gaps. Additionally, these vulnerabilities can be exploited to steal credentials and gain unauthorized access, posing risks to overall network security.

Banking Trojans Target Android Users by Mimicking Government and Legitimate Payment Apps

A financially motivated cybercrime group has been targeting Android users in Indonesia and Vietnam by deploying banking trojans disguised as legitimate government applications. They spoof Google Play Store and App Store interfaces to deliver malicious APKs through obfuscated WebSocket connections, evading traditional security measures. Analysis of over 100 malicious domains shows they use Alibaba ISP, Gname.com for domain registration, and share-dns.net nameservers, with rapid DNS resolutions occurring within about 10.5 hours during peak daytime hours in Eastern Asia. The group's delivery mechanism utilizes the Socket.IO library for real-time WebSocket connections, allowing them to stream malicious APKs in small chunks. The downloaded file, often named IdentitasKependudukanDigital.apk, installs a variant of the BankBot trojan family. Some simpler spoofed sites offer direct download links with mixed language code strings, indicating the use of multilingual templates. Domain registration data from August 2024 to September 2025 shows these threat actors frequently reuse TLS certificates and cluster spoofed sites on identical IP addresses, primarily hosted via Alibaba and Scloud. These domains share server titles and operate on Nginx, with first-seen DNS queries typically lagging 10.5 hours behind registration times. Infections communicate with command and control domains, highlighting a coordinated infrastructure. The campaign emphasizes the need for behavioral detection and real-time traffic inspection to identify anomalous WebSocket file transfers.

Banking Trojans Targeting Android Users Disguise as Government and Trusted Payment Apps

Since August 2024, a financially motivated threat group has targeted Android users in Indonesia and Vietnam by deploying banking trojans disguised as legitimate government identity and payment applications. The campaign utilizes intricate download mechanisms, reuses existing infrastructure, and employs template-based spoofed sites to evade detection while stealing user credentials. Researchers identified the campaign through suspicious HTML elements on counterfeit Google Play Store pages, with notable domains like icrossingappxyz[.]com featuring deceptive download buttons. The download process involved a WebSocket connection that streamed the .apk file in chunks, effectively bypassing network security filters. The downloaded file, often named IdentitasKependudukanDigital.apk, contained a variant of the BankBot.Remo trojan. Additionally, simpler spoofed sites imitated popular regional applications, such as a clone of the M-Pajak tax-payment app hosted on twmlwcs[.]cc, which was also identified as a BankBot loader. Other variants were found on domains like dgpyynxzb[.]com and ykkadm[.]icu, masquerading as legitimate banking applications. Over the past year, researchers identified over 100 domains associated with this campaign, primarily utilizing Alibaba ISP and registered through Gname.com Pte. Ltd. The operational patterns revealed a focus on Indonesian and Vietnamese victims, with domain registration and DNS queries peaking during Eastern Asia daytime hours. The campaign combines advanced obfuscation techniques with mass-template spoofing to circumvent security controls, highlighting the need for user vigilance and monitoring of unusual WebSocket traffic.

224 Malicious Android Apps on Google Play With 38 Million Downloads Delivering Malicious Payloads

A mobile ad fraud operation called "SlopAds" infiltrated the Google Play Store with 224 malicious applications, which collectively achieved over 38 million downloads across 228 countries. The operation utilized advanced steganography and obfuscation techniques to deliver fraudulent advertising payloads while avoiding detection. SlopAds activated its fraud system selectively based on specific advertising campaigns, generating around 2.3 billion fraudulent bid requests daily, primarily from the United States (30%), India (10%), and Brazil (7%). The malicious apps exploited Firebase Remote Config to retrieve encrypted data for downloading a primary fraud module named "FatModule." This module was concealed within PNG image files, allowing it to bypass traditional security measures. The FatModule included anti-analysis features to evade detection by security researchers. Google has since removed all identified SlopAds applications from the Play Store and implemented protections through Google Play Protect.
