A temporary restriction affects certain Dell devices with Intel Innovation Platform Framework drivers, which Microsoft plans to address in a future update. The cumulative update resolves a total of 622 Microsoft CVEs, including 416 affecting Windows components. Users are advised to verify and install the update promptly to secure the full suite of improvements.

The disruptions have sparked frustration among users and are widespread across various regions. Meta is investigating the situation and will provide updates as they work to resolve the issues.
The desktop version of Facebook experienced a global outage on Sunday morning, causing users to receive messages indicating their accounts were “currently unavailable due to a site issue.” The platform returned to normal operations just before noon after approximately three hours of downtime. During this period, the DownDetector website noted a spike in searches for “Facebook down,” peaking around 9 am. While the desktop version faced issues, the mobile app continued to function largely without disruption, although some users had difficulties uploading content or sending messages. Instagram users also reported problems, receiving error messages related to viewing and sharing posts. Meta had not issued an official statement regarding the outage. Approximately 1.5% to 2% of Facebook's estimated 3 billion monthly active users access the platform exclusively via desktop, while over 81% use mobile devices.
On Sunday morning, Facebook, Facebook Messenger, and Instagram experienced significant outages, with users globally reporting difficulties accessing their accounts, particularly on Facebook's desktop version. Many encountered an error message stating their accounts were temporarily unavailable due to a site issue. Reports of issues surged just before 9 AM, and while extensive, not all aspects of the platforms were affected. Nearly 60 percent of reported issues on Facebook were related to the website version, though many users accessed the platform via mobile apps. Users expressed frustration, noting that while Facebook worked on mobile devices, it was inaccessible on laptops. Some also faced issues with the Messenger app, which indicated it was outdated despite attempts to reinstall it. The timeline for resolution remained uncertain.
North Korea's Contagious Interview hackers have been using a deceptive strategy to target developers by posing as recruiters and embedding malware in SVG files. Elastic Security Labs discovered that the attackers hid malicious payloads within HTML comment blocks of these files, allowing the malware to evade antivirus detection. At the time of the findings, no antivirus engines flagged the compromised repositories, which included trojanized GitHub repositories disguised as coding challenges. The malware executed automatically at server startup and deployed four modules: a browser credential and cryptocurrency wallet stealer, a file stealer, a remote access Trojan, and a clipboard monitor. The campaign, tracked as REF9403, is part of the ongoing Contagious Interview operation attributed to North Korea's Lazarus Group, which aims to generate revenue through cryptocurrency theft. Developers are advised to audit any projects run from unsolicited sources and to monitor specific domains associated with the attack.
Approximately 16.9% of Windows client devices are still using Windows 10, while Windows 11 accounts for 78.8% of installations. Windows 10's market share has significantly declined from nearly 50% in mid-2025. The migration to Windows 11 is slowing, with remaining Windows 10 devices facing more complex and costly upgrade scenarios, including having three times as many active Common Vulnerabilities and Exposures (CVEs) compared to Windows 11. Legacy operating systems like Windows 7, Windows 8.1, and Windows XP are also factors in the migration challenges. Microsoft’s Extended Security Updates (ESU) program offers protection until October 2027 for consumers and until October 2028 for commercial customers.
The 1,024,000² 2b2t World Download Project is a significant Minecraft archiving achievement, preserving approximately 13.7 TiB of compressed world data from the 2b2t server, including a million-by-million-block section of the Overworld, and smaller captures of the Nether and End dimensions. It is the largest available Minecraft world download, released via torrent. The project took over a year to develop, involving a team that utilized 28 bot accounts to collect data, resulting in four distinct captures of varying sizes. The project was led by a developer named crayne, with key contributors including Fuch, mahan, and Steve3. The code and documentation are available on GitHub, and the project incurred over ,000 in server rental costs. 2b2t, established in December 2010, is one of the oldest Minecraft servers, known for its unyielding map and challenging environment, having hosted over 1,000,000 players. The creators assert that no AI was used in the project and have licensed their work under CC0 for community accessibility.
