CVE-2025-59287 is a critical Remote Code Execution (RCE) vulnerability affecting Windows Server Update Services (WSUS) . Here's a detailed breakdown of what it is, how it works, and what you should do about it: Overview Disclosed: October 2025 Patch Tuesday CVSS Score: 9.8 (Critical) Affected Systems: Windows Server 2012 through 2025 (including Server Core installations) Exploitability: Microsoft rates it as “Exploitation More Likely” Technical Details The vulnerability arises from unsafe deserialization of untrusted data in WSUS. Specifically, the GetCookie() endpoint in WSUS processes encrypted AuthorizationCookie objects without proper type validation. The deserialization occurs via .NET BinaryFormatter , which is known to be insecure when handling untrusted input. Attackers can send a crafted SOAP request to WSUS over port 8530 , containing a malicious AuthorizationCookie . The cookie is decrypted using a hardcoded AES key and then deserialized, allow...

Method 1: Using Command Line (e.g., on Windows or Linux) You can use the copy command (Windows) or cat (Linux/macOS) to combine files: On Windows (Command Prompt): Shell copy /b image.jpg + secret.zip output.jpg Show more lines image.jpg: the cover image secret.zip: the file you want to hide output.jpg: the resulting image with the hidden file You can still open output.jpg as a normal image, but if you open it with a zip tool (like WinRAR or 7-Zip), you'll see the hidden file. On Linux/macOS (Terminal): Shell cat image.jpg secret.zip > output.jpg   How to Extract the Hidden File To retrieve the hidden file: Open output.jpg with a zip tool (e.g., 7-Zip, WinRAR). You’ll see the hidden secret.zip contents inside.    Notes & Considerations This method doesn’t encrypt the hidden file it just hides it. Anyone who knows the trick can extract it. For more secure hiding, you can encrypt th...

   What's the Problem? USB keyboards and mice stop working in WinRE : After installing the update, USB input devices become unresponsive when booting into recovery mode. This means you can't navigate recovery options if your system fails to boot. Normal operation is unaffected : USB devices still work fine within the standard Windows 11 environment. Affected versions : Windows 11 24H2, 25H2, and Windows Server 2025. Workarounds and Cautions Avoid entering recovery mode unless absolutely necessary. Legacy PS/2 devices still work in WinRE, if available. Microsoft is working on a fix , but recovery patches KB5067039 and KB5067019 do not yet resolve the issue. Broader USB Issues Post-Update Some users also report: USB ports failing to recognize devices after updates earlier this year. Power flowing to ports but no data connectivity (e.g., camera lights up but doesn’t transmit data). Attempts to roll back drivers or reset BIOS have had mixed results.  Trouble...

  Google is not phasing out Chrome itself, but it is making major changes to some of its core features and initiatives:  What's actually being phased out? • Privacy Sandbox: Google has officially retired its Privacy Sandbox project, which aimed to replace third-party cookies with more privacy-preserving alternatives. This includes the shutdown of several APIs like Topics, Attribution Reporting, and Protected Audience. • Third-party cookie phase-out: Google has abandoned its long-standing plan to eliminate third-party cookies in Chrome. This reversal means tracking cookies will remain, despite years of development and regulatory scrutiny. • Chrome Apps: Support for Chrome Apps (not extensions) is being phased out gradually and will end completely by October 2028. This affects enterprise and education users who rely on legacy Chrome apps.  What’s staying? • Chrome browser itself is not going anywhere. It still dominates with over 70% of the global browser market. • ...
