Microsoft’s Free Upgrade Offer—Bad News For 240 Million Windows Users

Microsoft is encouraging approximately 240 million PC owners to recycle outdated devices, as they will not qualify for a free upgrade to Windows 11 without new hardware. The company emphasizes the importance of the Trusted Platform Module (TPM) 2.0, a security chip that determines eligibility for the upgrade and protects sensitive data. TPM 2.0 offers several security benefits, including data encryption, verification of trusted software, detection of physical tampering, and support for advanced security features in Windows 11. Currently, around 240 million PCs are estimated to be ineligible for the upgrade, which may hinder the adoption of Windows 11 and leave many devices vulnerable to cyber threats.

Microsoft is trying to convince Windows 10 users that TPM 2.0 is worth the upgrade

Windows 10 has a user base of 54.2%, while Windows 11 has 42.69%. The requirement for TPM 2.0 in Windows 11 poses a barrier for users considering an upgrade. Microsoft highlights the benefits of TPM 2.0, including data protection, software integrity, physical tamper resistance, and support for advanced security features. Microsoft encourages users to transition to Windows 11 for enhanced security, improved user experience, and future readiness. However, the adoption of TPM 2.0-compatible CPUs has not met expectations, and the end of support for Windows 10 may prompt more users to upgrade to Windows 11.

6 overlooked security practices I implemented at home and I regret not using sooner

- Safeguarding technology is crucial in the digital age due to potential threats from various devices. - Two-factor authentication (2FA) enhances online account security by requiring a second code sent to a phone, email, or authentication app. - Biometric verification methods and hardware authentication devices like YubiKeys can further enhance security. - Backup codes should be printed when setting up 2FA, and passkeys offer a passwordless solution for securing accounts. - Ransomware can lock users out of data until a ransom is paid, and Windows 10 and 11 have a feature called Controlled Folder Access (CFA) to protect essential folders. - Windows Security provides baseline protection for PCs, and users should regularly check for updates and conduct manual scans. - Microsoft's PC Manager utility enhances system security by offering features for storage and app management alongside virus scanning. - Securing web browsers is vital, with unique settings available in browsers like Microsoft Edge, Firefox, and Chrome to improve privacy and security. - Regularly clearing browsing history and keeping browsers updated helps mitigate risks from malware and phishing attacks. - Securing Wi-Fi routers involves changing the default admin password and SSID, using strong encryption like WPA3, and regularly updating firmware. - Custom firmware like DD-WRT or OpenWrt can enhance router security and functionality.

Google’s Play Store Warning—Do Not Update This Setting

A sophisticated trojan named TsarBot is targeting over 750 legitimate banking and shopping applications on Android devices. It overlays a counterfeit login screen on real apps to capture user credentials. TsarBot is believed to have Russian origins and can remotely control the device's screen, simulating user interactions and capturing device lock credentials through a deceptive lock screen. The trojan is typically installed from phishing websites, where a dropper application delivers the TsarBot APK file. Once installed, it disguises itself as the Google Play Services app and urges users to enable Accessibility services. Users are advised to avoid installing apps from outside the Google Play Store, ensure Play Protect is enabled, and only enable Accessibility Services when necessary to mitigate risks.

Android users ALERT! Google has an update but you need to stop installing THESE apps?

Google's AI-driven threat detection and security measures blocked approximately 2.36 million policy-violating applications from being released on the Play Store last year. In February, Google removed hundreds of malicious applications that were infecting devices with adware and malware. Over 50 times more Android malware originates from internet-sideloaded sources compared to those found on the Play Store. Google is expanding its Play Protect feature across all applications and the upcoming Android 15 will introduce live threat detection. Sophos warned about PJobRAT malware, which can steal SMS messages, contacts, and files from infected Android devices. Experts advise against sideloading apps unless their legitimacy and security are certain.

Do Macs need antivirus? Debunking the security myth

Many users believe that Macs are immune to cybersecurity threats, leading them to neglect protective measures. This perception originated from Apple's marketing and the historical lower targeting of Macs due to their smaller market share. However, as the popularity of Macs has increased, so has the development of malware aimed at macOS. Reports indicate that malware targeting Macs has now outpaced that targeting Windows on a per-device basis. While macOS includes strong security features like XProtect, Gatekeeper, and System Integrity Protection, these are not foolproof. XProtect only defends against known malware, leaving users vulnerable to new threats. Macs are susceptible to various types of malware, including adware, Trojans, and phishing attacks. Antivirus software is important for Macs as it protects against evolving malware, shields users from phishing and online scams, enhances privacy protection, and prevents cross-platform threats.

This dangerous new Windows malware hides from your antivirus while impersonating a popular PC brand

A new strain of malware called CoffeeLoader targets Windows users by pretending to be an ASUS utility, specifically imitating ASUS's Armoury Crate. It has sophisticated evasion techniques that allow it to bypass antivirus software. Once installed, it deploys infostealers like Rhadamanthys Infostealer to extract sensitive information. CoffeeLoader operates undetected by executing code on the GPU instead of the CPU, using Call Stack Spoofing to disguise its activities, and employing Sleep Obfuscation to encrypt itself in memory when inactive. It also exploits Windows Fibers to evade detection. To protect against CoffeeLoader, users should download Armoury Crate only from the official ASUS website and be cautious of deceptive links and ads that may lead to malware installation.
