What a smart firewall does and why it matters on home Wi-Fi

Home Wi-Fi connects various devices and presents security risks, making firewalls important for network protection. A router firewall is built into the home router and protects all connected devices, while a software firewall operates on individual devices for additional security. Inbound traffic is data coming to a device, while outbound traffic is data leaving it; firewalls analyze this traffic to manage connections. Network security is critical as sensitive information is often accessed on devices used for leisure, and remote work increases data overlap. Firewalls can control network connections and filter unwanted traffic but cannot replace weak passwords or antivirus protection. To enhance home network security, users should secure router settings, keep routers updated, strengthen Wi-Fi access, check connected devices, and replace outdated routers. A comprehensive security strategy includes keeping software updated, using multifactor authentication, being cautious with links, and strengthening firewalls with antivirus protection. Protecting valuable data is essential, and understanding ransomware risks is crucial. The 3-2-1 backup strategy involves maintaining three copies of data on two different storage types, with one copy offsite. Regularly testing backups and knowing how to respond to ransomware incidents are also important.

Autoscaling Lakebase Postgres

Choosing a database instance size without prior knowledge of the workload can lead to inefficiencies and excessive compute usage. Lakebase Postgres addresses this with an autoscaling feature that eliminates manual sizing, utilizing in-place VM resizing and a monitoring algorithm for CPU, memory, and working set size. Lakebase Postgres separates compute and storage layers, allowing independent resizing of compute nodes without affecting the database. The autoscaling algorithm relies on three signals: CPU load (cpuGoalCU), memory use (memGoalCU), and compute-cache working set size (lfcGoalCU). The CPU load is monitored every five seconds, aiming to maintain it at or below 90% capacity. Memory usage is tracked at two frequencies: overall memory every five seconds and Postgres-specific memory every 100 milliseconds, with a goal to keep usage below 75% of allocated RAM. The compute cache evaluates active data access efficiency, adjusting size based on workload. The working set is estimated using a modified HyperLogLog algorithm that records timestamps for page accesses, allowing for distinct page estimates over various time frames. The algorithm projects future working-set growth to allocate sufficient cache while capping it at 75% of RAM. Resizing the compute involves four components: the autoscaler-agent, vm-monitor, Kubernetes scheduler, and NeonVM. Scaling up occurs when any of the three goals indicate a need for more resources, while scaling down includes verification to ensure sufficient memory remains for operations. Timely adjustments in both directions are prioritized to minimize costs.

Fake Microsoft Security Scan Tells You to Remove Antivirus—Then Scammers Ask for Remote Access

A new web-based scam is using counterfeit Microsoft-branded security scans to deceive users into uninstalling their antivirus software. The scam websites conduct fake inspections, reporting false security failures and claiming third-party antivirus products are unsupported by Windows. They gather browser information to create customized-looking scan reports and aim to mislead victims into a fraudulent refund process. Investigators have identified 11 related scam sites under the name SysScan, which present themselves as legitimate Microsoft security checks. The scam does not involve file downloads but relies on convincing websites, fabricated security scores, and personal information forms. The scan results are hard-coded, and the security score is limited to a range between 13 and 30 out of 100. The scams instruct users to uninstall antivirus software, which is misleading since Windows does not cease support for third-party antivirus solutions. The scam sites request extensive personal information, including names, addresses, phone numbers, and banking details, and redirect victims to a page claiming a refund manager will call shortly. This process allows scammers to gain remote access to victims' computers. Indicators of compromise include specific IP addresses and domains associated with the scam.

ValleyRAT Backdoor Hides in Signed Adware That Users Add to Antivirus Exclusions

Silver Fox is linked to the distribution of a backdoor malware called ValleyRAT, disguised as the legitimate QN Wallpaper adware application. Once installed, ValleyRAT provides complete control over the compromised machine. The malware uses DLL sideloading to operate under the guise of a legitimate process, bypassing security measures. It disables Windows Defender and adds itself to autorun entries, and can mark its process as critical, causing system crashes if terminated. Kaspersky has identified specific indicators of compromise (IoCs) including hashes, command-and-control servers, and associated domains. In 2026, Kaspersky recorded over 100,000 detections of ValleyRAT affecting more than 1,500 unique users, mainly in China and India.

New JK Terror Tactic: Pornography Apps, Tor Network Used For Secret Messaging

Security agencies in India have observed a shift in the tactics of terrorist groups, which are now using pornography websites and niche encrypted applications for communication instead of traditional social media. These groups, often collaborating with Pakistan's ISI, utilize platforms with real-time chat tools disguised as dating services to send instructions to recruits in Jammu and Kashmir. Security agencies are monitoring various digital tools, including Tor-based applications like Coatex and Conion, which obscure user identities. Some privacy-focused platforms do not require phone numbers for registration, complicating tracking efforts. Despite bans on certain pornography applications in India, they are still accessed illegally via VPNs, which mask users' IP addresses. The use of the Tor network presents additional tracking challenges, as it obscures data origins and destinations. Security agencies are adapting their surveillance methods in response to these developments, which include the use of virtual SIM cards in terrorist activities, as highlighted during investigations into the 2019 Pulwama attack.

After GTA 6: Extended Look Showed Rockstar’s Game Running at 30FPS, Tech Experts Say a 60FPS Console Version Is ‘Extremely Unlikely’ and ‘Genuinely Challenging’ Even on PC

Digital Foundry has analyzed the recent 27-minute reveal of Rockstar's Grand Theft Auto 6, which showcased gameplay at 30 frames per second (fps). The game is set to launch on PlayStation 5 and Xbox Series X/S this November, with a focus on maximizing visual detail at the fixed frame rate. Significant advancements in character rendering, including skin shading and hair simulation, have been noted. The internal rendering on the PS5 is speculated to operate at 1440p without dynamic resolution scaling, although this may result in some softness and aliasing. Digital Foundry expresses skepticism about the feasibility of a 60fps mode on current consoles, citing the game's design balance and the complex CPU demands of its detailed world. Future console iterations and a PC release may support higher resolutions and features like DLSS, but achieving 60fps could still be challenging. IGN has provided exclusive insights into various aspects of the game, including its romance system and expansive map.
