Microsoft Prepares Windows Code Signing for Stronger Cryptography

Microsoft has issued an advisory to IT teams and software developers regarding significant changes in Windows code signing due to the expiration of the Windows Production PCA 2011 certificate in October 2026. The transition will involve stronger cryptographic algorithms, including RSA-3072 and SHA-384, which may cause compatibility issues for applications that rely on hardcoded certificate checks or outdated cryptographic standards. Microsoft plans to implement post-quantum cryptography by default for Windows code signing in 2027. IT administrators are encouraged to assess their software environments, confirm vendor compliance with supported trust-validation mechanisms, and ensure applications are tested against the new certificate hierarchy and signing algorithms. Organizations with private trust stores must establish processes for recognizing and deploying legitimate Microsoft certificate updates.

Best Ransomware Protection 2026: Tested and Ranked

Ransomware protection is best approached as a layered strategy rather than relying on a single solution. The effectiveness of software is significantly enhanced by maintaining a well-managed backup that is disconnected during an attack. Five tools were evaluated based on their default settings, focusing on behavioral detection, protected folders, file rollback, and real-time protection. 1. Norton 360: Rated as the best overall ransomware protection, it offers comprehensive features including behavioral monitoring, protected folders with dual alert modes, and 50 GB of cloud backup within a single subscription. It has a perfect score in advanced threat assessments. 2. Bitdefender: Recognized for its file rollback and remediation capabilities, it provides an effective "undo" feature that restores files, although this feature is turned off by default. 3. Avast One Free: The best free ransomware protection option, it includes a dedicated shield on the free Windows tier and has achieved a perfect score in advanced threat assessments. 4. NordVPN Threat Protection Pro: Best for blocking the delivery route of ransomware, it prevents downloads before encryption starts but cannot stop the process once it has begun. 5. McAfee: Best for protecting multiple devices simultaneously, it offers unlimited device coverage on most plans with integrated ransomware defense in its scanning engine. Modern ransomware protection software has shifted from signature matching to focusing on monitoring the behavior of processes interacting with files. The four essential layers of protection include behavioral monitoring, protected folders, automatic file rollback, and backup. Most users do not need a separate anti-ransomware product, as these features are typically included in main antivirus suites, with the key consideration being whether these features are activated. The rankings of the tools were based on whether the ransomware protection layer is enabled by default, the extent of file recovery when intervention occurs, and the frequency of false positives during normal use. - Norton 360: Best overall, with protection enabled by default and a perfect score in advanced threat testing. - Bitdefender: Best for file rollback, but the rollback feature is disabled by default. - Avast One Free: Best free option, with a perfect score in advanced threat assessments but lacks rollback capabilities. - NordVPN Threat Protection Pro: Effective at blocking malware downloads but does not provide rollback or backup features. - McAfee: Suitable for families with multiple devices, offering automatic backup of flagged files but lacks user-configurable protected folder options. The effectiveness of ransomware protection tools is primarily assessed through behavioral responses rather than library matching. Backup remains a critical layer of defense, functioning even when other layers fail.

Take-Two’s former AI guy is, in a twist, skeptical about AI now: ‘The guy should be selling you the gold if he’s actually got the gold’

Take-Two Interactive laid off AI specialist Dicken and a significant portion of the AI team after a year, reflecting industry volatility. Dicken expressed skepticism about generative AI's role in creative processes, noting that many creatives view it as a departure from intentionality. He observed a divide in public perception, with Western audiences more resistant to generative AI compared to Asian audiences. Dicken highlighted challenges in integrating AI into workflows, including vendor lock-in and price volatility, drawing parallels to the Unity engine's pricing crisis. He noted a gold rush mentality among corporations eager to adopt AI, often without proper safeguards. Looking forward, Dicken believes AI will bring long-term changes to gaming but should be seen as a tool to enhance experiences rather than a revolutionary force. He advocated for a thoughtful approach to incorporating AI-generated content, emphasizing the need for alignment with a game's fundamental thesis.

The Truth About Android Antivirus Apps in 2026

Most Android users consider third-party antivirus apps unnecessary due to the robust built-in security features of modern Android smartphones. However, Android devices are still vulnerable to viruses, malware, and security breaches, with a 2025 Gen threat report indicating a tripling of malicious push notifications and an increase in spyware issues. Google Play Protect blocked 27 million malicious apps in 2025 and conducts scans to manage security. Android employs sandboxing, regular security updates, and an opt-in permissions system to protect users. Upcoming features include phone call spoofing protection and enhanced live threat detection capabilities. Social engineering tactics, such as phishing and fake tech support calls, pose significant risks that antivirus software cannot address. Connecting to open Wi-Fi networks can expose devices to risks, and malicious push notifications can mislead users. Third-party antivirus apps may be beneficial in high-risk scenarios, such as public Wi-Fi networks or when sideloading apps, providing an additional layer of protection.
