Preventing App-Based Threats on Android Devices

By 2025, the Android platform faces increasingly sophisticated app-based threats, including ransomware, fake apps, social engineering, and remote access attacks. Cybercriminals exploit Android's open architecture, prompting the need for advanced security measures. Android's security architecture includes: 1. Google Play Protect: Scans applications before installation using real-time machine learning to detect emerging malware and deceptive tactics. 2. Application Sandboxing: Isolates apps to prevent data access between them, utilizing Linux permissions and SELinux policies. 3. App Signing and Code Integrity: Requires cryptographic signatures for apps, complicating the introduction of rogue certificates and runtime modifications. Advanced protections include Runtime Application Self-Protection (RASP) for high-security apps, which monitors behavior in real time, and secure coding practices that encourage regular code reviews, strong authentication, and data encryption. User vigilance is crucial, emphasizing responsible downloading, limiting permissions, keeping software updated, enabling two-factor authentication, and being cautious with public Wi-Fi. Google continuously updates security measures, ensuring older devices receive new protections, while collaboration with the security community aids in identifying and countering emerging threats.

Running I/O intensive workloads on PostgreSQL with Amazon EBS io2 Block Express

Databases are essential for organizations, and their performance is critical to user experience and operational efficiency. AWS introduced Amazon Elastic Block Store (Amazon EBS) io2 Block Express in December 2020 to address performance issues related to storage latency during database operations. This solution enhances storage management for high-performance database servers, supporting up to 256,000 IOPS and 4,000 MiB/s throughput per volume, with a maximum volume size of 64 TiB and sub-millisecond disk I/O latency. A performance comparison was conducted between PostgreSQL databases on Amazon EBS gp3 and io2 Block Express, utilizing the HammerDB benchmarking tool. The analysis involved four tests: OLTP Load test, OLTP Stress test, OLAP Load test, and OLAP Stress test, using r5b.24xlarge EC2 instances. Results indicated that io2 Block Express outperformed gp3 by 2.08 times in transactions per minute (TPM) and provided significantly lower latency for both OLTP and OLAP workloads. Key differences between gp3 and io2 Block Express include durability, with io2 offering 99.999% durability compared to gp3's 99.8% – 99.9%. The maximum IOPS for gp3 is 16,000, while io2 supports up to 64,000 IOPS. Pricing for gp3 is approximately ,375.36/month, while io2 Block Express costs around ,408/month, reflecting its premium performance capabilities. In benchmarking tests, io2 Block Express demonstrated superior performance, achieving 3.95 times faster average performance than gp3 across all scenarios. It is particularly suitable for mission-critical applications requiring consistent sub-millisecond latency and high durability.

Microsoft Confirms Emergency Update For Windows Users

Microsoft has released an emergency update for Windows 10 due to issues following May’s mandatory security update, which caused BitLocker Recovery screens and Blue Screens of Death for users. The problem primarily affects devices with Intel Trusted Execution Technology on 10th generation or later Intel vPro processors. Users who encounter these issues are advised to disable Intel VT for Direct I/O and Intel TXT in BIOS/UEFI settings, install update KB5061768, and then re-enable the settings. Microsoft has stated that its support team cannot retrieve lost BitLocker recovery keys. This issue mainly impacts enterprise users, as consumer devices generally do not use Intel vPro processors.

Windows Remote Desktop Gateway UAF Vulnerability Allows Remote Code Execution

A critical vulnerability, designated as CVE-2025-21297, has been identified in Microsoft’s Remote Desktop Gateway (RD Gateway) due to a use-after-free (UAF) bug linked to concurrent socket connections during the service's initialization. This flaw, located in the aaedge.dll library within the CTsgMsgServer::GetCTsgMsgServerInstance function, allows multiple threads to overwrite a global pointer, leading to potential arbitrary code execution. The vulnerability affects multiple versions of Windows Server, including 2016, 2019, 2022, and 2025. Microsoft released security updates in May 2025 to address the issue, implementing mutex-based synchronization. The updates are KB5050011 for Windows Server 2016, KB5050008 for Windows Server 2019, KB5049983 for Windows Server 2022, and KB5050009 for Windows Server 2025. Security experts recommend applying these patches promptly and monitoring RD Gateway logs for unusual activity.

How to stop Android apps running in the background

Experiencing unexpected battery drain on Android devices can be caused by background apps. To manage these apps and alleviate battery issues, users can activate the Adaptive Battery feature by navigating to Settings > Battery > Battery Saver > Adaptive Battery and toggling it on. Regular updates for both the Android system and applications can improve battery performance. Users can check for Android updates in Settings > System > Software updates and for app updates in the Google Play Store under Manage apps & device. To monitor battery usage, users can go to Settings > Battery > Battery usage to identify which apps consume the most power. For RAM usage, enabling Developer options allows users to see which apps are using memory by going to Settings > About phone > Build number (tap seven times) > System > Developer options > Running services. Users can stop or uninstall background apps by navigating to Settings > Apps > See all apps, selecting the app, and choosing to force stop or uninstall it. To limit background activity for specific apps, users can enable "Pause app activity if unused" or toggle off "Allow background usage" in the app's battery usage settings. Some manufacturers offer built-in options for managing background apps, and third-party apps like Greenify can also help. Common battery-draining apps include social media and streaming services.
