    Active Directory Security Tip #2: Active Directory User Accounts
    There are several different types of user accounts – at least how they are used. There are standard user accounts, service accounts, and admin accounts. There are numerous user account settings that can make them vulnerable. These configurations include: PowerShell code (using Active Directory PowerShell module):https://github.com/PyroTek3/Misc/blob/main/Get-VulnerableUserAccounts.ps1  ( 5 min )

    Active Directory Security Tip #1: Active Directory Admins
    A critical part of Active Directory security is regularly reviewing your AD admins.

    Add ChatGPT MCP server—Another setback for OpenAI
    OpenAI has finally rolled out Model Context Protocol (MCP) support for all ChatGPT subscription plans. However, the implementation is surprisingly basic and falls short of the MCP support offered by Anthropic's Claude Desktop. Currently, ChatGPT doesn't support local MCP servers (SDIO), and you can only add remote MCP servers (SSE, Streamable HTTP). There's also no MCP server catalog, and the worst part is that GPT-5 isn't fully MCP-ready. Source

    Citrix forces customers to migrate to License Activation Service (LAS)
    Citrix has announced a fundamental shift in managing product licensing by replacing traditional file-based licensing with a cloud-based License Activation Service (LAS). This mandatory transition affects all on-premises Citrix components, with file-based licensing reaching end of life on April 15, 2026. The change simplifies license management by eliminating manual license file downloads and uploads. The change simplifies license management by eliminating manual license file downloads and uploads. LAS requires registering with Citrix Cloud and periodic connectivity to maintain activations; limited offline operation is supported via a grace period. Source

    The Security Time Capsule: Evolving Beyond Legacy Pen Testing
    Legacy point-in-time penetration testing was first implemented in the 1960s, back when networks were static, attackers were hobbyists, and change happened slowly. We live in a very different world now. The practice of testing annually was shaped for a world that no longer exists; one without dynamic cloud infrastructure, identity sprawl, or AI-accelerated threats.

    Windows UAC bug after the August 2025 update
    Microsoft's August 2025 update caused a Windows UAC bug that triggers unplanned User Account Control (UAC) prompts throughout Windows environments. This problem originates from security improvements included in the August 12, 2025, cumulative patches for all supported Windows editions—specifically KB5063878 (Windows 11 24H2), KB5063875 (Windows 11 22H2/23H2), and KB5063709 (Windows 10 22H2 and Windows 10 Enterprise LTSC 2021)—which resolved CVE-2025-50173 but inadvertently created compatibility problems with Windows Installer maintenance functions.

Even after patching the code to bypass authentication, most interesting operations required interacting with handlers and state we initially omitted. In this part, we explain how we increased coverage and applied different fuzzing strategies to identify more bugs. Some functionalities require additional configuration options. We tried to enable many available features to maximize the exposed attack surface. This helped us trigger code paths that are disabled in the minimalistic configuration example. However, to simplify our setup, we did not consider features like Kerberos support or RDMA. These could be…  ( 9 min )

    Sneaking Invisible Instructions by Developers in Windsurf
    Imagine a malicious instruction hidden in plain sight, invisible to you but not to the AI. This is a vulnerability discovered in Windsurf Cascade, it follows invisible instructions. This means there can be instructions in a file or result of a tool call that the developer cannot see, but the LLM does. Some LLMs interpret invisible Unicode Tag characters as instructions, which can lead to hidden prompt injection. As far as I can tell the Windsurf SWE-1 model can also “see” these invisible characters, but the SWE-1 is not yet capable of interpreting them as instructions.  ( 2 min )

    OpenAI recently released its first open-weight models, gpt-oss-20b and gpt‑oss-120b, which you can download and run with Ollama. If security and privacy are essential when using AI models, you might not want to use the vendor's chat UI or API.
