Why I Use Additional Antivirus Protection on Top of Microsoft Defender

Microsoft Defender has evolved into a reliable security tool, integrating seamlessly with the Windows operating system and offering features such as real-time malware scanning, cloud-based threat intelligence, collaboration with the Windows firewall, and ransomware protections. It receives automatic updates through Windows Update, providing users with up-to-date threat definitions. While Defender is sufficient for users with straightforward online activities, those engaging in riskier behaviors or handling sensitive information may benefit from additional protection. Some antivirus solutions offer features that Defender lacks, such as enhanced web protections, phishing defenses, and parental controls. The text mentions that the author uses Bitdefender alongside Microsoft Defender for added security, citing its stronger web protections and broader range of tools. It emphasizes that effective security also relies on user habits, including keeping software updated, avoiding suspicious downloads, using strong passwords, and regularly backing up data.

‘DLSS fundamentally makes no sense’ says Minecraft creator Notch, but actually it kinda does

Markus Persson, known as Notch, criticized Nvidia's Deep Learning Super Sampling (DLSS) technology on social media, stating that it "fundamentally makes no sense" because it uses the same hardware to run a neural network for frame generation. Community responses clarified that DLSS utilizes specialized hardware, specifically Tensor Cores, optimized for machine learning tasks. Some commentators suggested a focus on raw raster performance instead of machine learning enhancements. Nvidia's vice president, Bryan Catanzaro, emphasized the need for smarter graphics rendering approaches, arguing that brute force methods are inefficient. Current testing of DLSS and Frame Generation is being conducted by an expert named Nick, who is analyzing the GPU's workload in rendering frames. While DLSS has supporters, it also faces criticism, particularly regarding its performance on lower-spec graphics cards.

Man admits to locking thousands of Windows devices in extortion plot

A former core infrastructure engineer, Daniel Rhyne, admitted to locking Windows administrators out of 254 servers during an extortion attempt against his employer in Somerset County, New Jersey. Rhyne accessed the company's network without authorization from November 9 to November 25, deleting network admin accounts and altering passwords for 13 domain admin accounts and 301 domain user accounts to "TheFr0zenCrew!". He also scheduled tasks to modify passwords for two local admin accounts affecting 3,284 workstations and planned to shut down random servers and workstations in December 2023. On November 25, he sent a ransom email demanding 20 bitcoin, claiming IT administrators were locked out and server backups erased. Forensic investigators found he used a concealed virtual machine to plan his actions. Rhyne was arrested on August 27 and faces charges related to hacking and extortion, with a potential maximum sentence of 15 years in prison.

This is the best Google Pay feature you’re not using in India

Google Pay's Tap to Pay feature, launched in 2020, allows contactless payments using NFC technology. Initially compatible with only two banks, it now works with most major debit and credit cards in India. Users can add their cards to Google Pay, and payments can be made by selecting the card and tapping the phone near a point-of-sale machine. The feature supports most Visa and MasterCard cards issued in India, while American Express cards are excluded. There are no transaction limits, and a PIN is required for high-value transactions. The setup process involves adding card details and authenticating via SMS. Tap to Pay can also be used internationally, except in China.

Which messaging app takes the most limited approach to permissions on Android?

Messaging applications Messenger, Signal, and Telegram exhibit significant differences in permissions and operational behaviors that impact user privacy. Telegram has the fewest total permissions at 71, with 25 classified as dangerous; Signal requests 72 permissions, including 19 dangerous ones; and Messenger requests the most at 87, with 24 dangerous permissions. Messenger also has the highest number of vendor-specific unknown permissions. Access to sensitive resources is crucial for messaging functionalities, with permissions for contacts, camera, microphone, location, storage, and calendar being essential. Telegram and Messenger request additional system-level permissions, while Signal is more conservative and does not request certain permissions like phone-call control or overlay windows. The analysis, using the Mobile Security Framework (MobSF), indicates all three apps are in the medium risk category, with Messenger having more flagged issues. Telegram allows cleartext connections by default, potentially exposing traffic, while Signal uses encrypted connections by default and only permits limited cleartext traffic for certificate checks. Messenger's issues include world-writable files and remote debugging enabled in WebViews. Messenger uses third-party SDKs, while Signal and Telegram do not disclose third-party trackers. All three utilize Firebase Cloud Messaging for notifications without sensitive data leakage. Data exchange patterns show Messenger primarily routes traffic through North America, while Telegram and Signal focus on Europe with some additional connections in the U.S. and Asia.

Minecraft creator Notch says ‘DLSS fundamentally makes no sense’, but the X comments say ‘um, actually’

Markus Persson, known as Notch, criticized Nvidia's Deep Learning Super Sampling (DLSS) technology on social media, arguing that it is illogical to use the same hardware that struggles to run games at reasonable speeds to operate a neural network for generating additional frames. He compared DLSS to anti-aliasing, suggesting both technologies complicate the rendering process. Nvidia's vice president, Bryan Catanzaro, highlighted a shift in the industry towards artificial intelligence to improve graphics rendering, stating that traditional methods are no longer sufficient. He emphasized the need for smarter approaches to optimize resource use in graphics rendering. Nick, a tester, is evaluating DLSS and Frame Generation, illustrating the GPU's workload in rendering versus AI interpolation of frames.

Malwarebytes highlights Microsoft findings on WhatsApp attachments used in Windows attacks

A campaign targeting Windows users exploits WhatsApp attachments to execute a malicious .vbs script. Victims receive what appears to be a harmless attachment, which, when opened, duplicates legitimate Windows tools into a hidden folder and renames them to avoid detection. These tools are then used to download additional malware from reputable cloud services, disguising the malicious activity. The malware seeks administrator privileges by altering User Account Control settings and registry entries for persistence. It ultimately installs remote-access software and other payloads to maintain control over the compromised device. Malwarebytes recommends safety measures such as avoiding unsolicited attachments, enabling file extensions, using updated anti-malware tools, downloading software from official sites, being cautious of unexpected UAC prompts, and keeping systems updated.

How to use and deploy Android Work Profile in your business

The mobile device has become a dual-purpose tool for personal and professional needs, enhancing productivity but also introducing security challenges for organizations with bring-your-own-device (BYOD) policies. Samsung addresses these challenges with its Android Work Profile feature, which separates business applications and data from personal content on devices like the Galaxy S26 Series, Galaxy Z Fold7, and Galaxy Z Flip7. Android Work Profile creates two isolated profiles on a single device, allowing IT teams to manage corporate applications while keeping personal information private. IT administrators can monitor work profile applications and data but cannot access personal profiles, ensuring employee privacy. Employees can easily switch between work and personal applications and activate a “pause work apps” feature during off-hours. To set up Android Work Profile, organizations need an Enterprise Mobility Management (EMM) solution and the Android Device Policy app. The Samsung Knox Suite provides tools for managing and securing devices, including Knox Mobile Enrollment and Knox Attestation. Android Work Profile benefits businesses by enhancing data security and reputation while promoting work-life balance for employees.
