AI-Generated PowerShell Tool Maps Active Directory in Rapid Breach

Cybersecurity researchers flag a June 2026 intrusion where attackers used an AI-generated, vibe-coded PowerShell script to enumerate a Windows Active Directory after gaining RDP access to a domain-joined server. The tool locates the Domain Controller, maps AD users, computers, groups, OUs, and trusts, creates a staging area, and exports results (including AD_Report.html). Attackers then deployed s5cmd and SharpShares to locate data repositories, exported data to CSV, archived it, and exfiltrated it to a remote server. The incident highlights how AI-assisted tooling lowers entry barriers and accelerates reconnaissance, aligning with established smash-and-grab playbooks, while a related Sygnia report notes AI-enabled cloud intrusions can scale quickly using credentials and cloud weaknesses rather than new malware.

Wipe Copilot from Windows 11: Two Practical Methods

Lifehacker outlines two ways to remove Microsoft Copilot from Windows 11: (1) use the Group Policy Editor (gpedit.msc) to disable Copilot or turn off Windows Copilot, a feature available on Windows 11 Pro or higher and only if Copilot hasn’t been launched in the last 28 days; (2) run a GitHub script from RemoveWindowsAI in PowerShell to remove Copilot and other AI features from all apps, with caveats about antivirus blocks and reviewing the script first. Microsoft has begun dialing back Copilot, but a complete off switch isn’t perfect yet.

Preparing Windows for the June 2026 Secure Boot Certificate Update

Secure Boot certificates expire in June 2026. Check if your PC already has updated certificates with a PowerShell check, then install any pending Windows updates and OEM firmware updates. If firmware updates aren’t available, use Microsoft’s registry-based workaround and reboot as directed. Windows 10 users may need Extended Security Updates to receive the update.

Windows Store Gains a Command-Line Interface for Install and Update

Microsoft introduced a PowerShell-based CLI for the Microsoft Store, enabling search, installation, and updates of Store apps directly from the command line, including bulk updates; however, it only works with Store-listed apps and may not include popular programs like Chrome or Paint.NET.

DNS Channel Used to Deliver PowerShell Payload in ClickFix Attacks

A new ClickFix variant uses a DNS-based delivery channel: victims are prompted to run nslookup in the Run dialog, querying an attacker-controlled DNS server. The DNS response contains a PowerShell payload that, when executed, downloads a ZIP with a Python runtime and malware scripts, establishes persistence, and installs ModeloRAT. This marks the first known use of DNS for staging and delivering ClickFix payloads, enabling on-the-fly payload updates and blending with normal DNS traffic instead of relying on HTTP.

Undetectable PowerShell Execution via WinRAR SFX Archives

Hackers are using WinRAR self-extracting archives to plant backdoors without triggering security agents on target systems. The SFX files contain harmless decoy files and are password-protected. The attackers add malicious functionality to the SFX files, allowing them to run PowerShell, Windows command prompt, and task manager with system privileges. This type of attack is likely to remain undetected by traditional antivirus software. Users are advised to use appropriate software to check the content of SFX archives and look for potential scripts or commands scheduled to run upon extraction.

"Microsoft addresses BitLocker vulnerabilities with PowerShell scripts"

Microsoft has released PowerShell scripts to fix a BitLocker security bypass vulnerability in the Windows Recovery Environment (WinRE) for Windows 10 and 11 systems. The vulnerability could allow access to encrypted data in storage devices. The scripts enable enterprises to automatically update WinRE images to protect Windows devices. The flaw can only be exploited on systems with the winre.wim on the recovery partition.
