Welcome, institutional sovereigns.

Well, you probably know where this is going…

A viral forensic dump shows autonomous delivery agents in an Azure tenant plowing through virtual machine boundaries like determined little robots… emphasis on “plowing.”

The siphoned identity tokens bounce over local admin curbs, drag unauthenticated PoP keys, and barrel through SSO intersections with the confidence of an adversary who definitely didn’t check their cryptographic signatures.

One GitHub comment nails the real 2026 advancement here: “Apparently you can just mix a stolen CheckAccess token with your own PoP token to get the tenant-wide RCE moving again.” Would anyone else watch CyberBivash’s Funniest Cloud Escape Movies as a half-hour special? Cause we would!

Sure, it’s funny now. But remember these are live Azure production environments collecting real-world data at scale… something cloud regulators are nervous to fully allow. While we laugh at today’s fails, the 2026 siphoning syndicates are learning from millions of chaotic IAM interactions. That’s a massive adversarial training advantage.

Here’s what happened in Infosec Today:

The WAC God Mode: We break down CVE-2026-20965, the critical 7.5 flaw that turns a single compromised Azure VM into a tenant-wide RCE vector.
Token Validation Failure: Cymulate Research Labs unmasks a terminal logic flaw in Windows Admin Center’s SSO implementation—liquidating the boundary between machines.
Mastercard’s Agent Pay: Unveiled infrastructure to enable AI agents to execute autonomous purchases—and potentially drain unhardened Azure billing enclaves.
Neural Breakthroughs: JUPITER supercomputer simulates 200B neurons (comparable to the human cortex)—a massive training siphon for the next-gen autonomous exploits.

DEEP DIVE: CLOUD LIQUIDATION

One Machine to Rule Them All: How CVE-2026-20965 Turns Local Admins into Global Threats

You know that feeling when you’re auditing a 10,000-line identity log and someone asks about the KID identifier in the PoP token? You don’t re-read everything. You flip to the Azure SSO handler, skim for CheckAccess token validation, and piece together the session hijacking point. If you have a really great memory (and more importantly, great recall) you can reference the token mismatch right off the dome.

Current Windows Admin Center (WAC) servers? Not so smart. They try cramming every unauthenticated SSO request into their working memory at once. Once that token buffer fills up, performance tanks. Cryptographic signatures get jumbled due to what researchers call “context rot”, and authorization boundaries get lost in the middle.

The fix, however, is deceptively simple: Stop trying to remember every identity. Validate the UPN match.

The new CVE-2026-20965 Exploit flips the script entirely. Instead of forcing every connection through a strict auth window, it treats the Azure Windows Admin Center like a searchable, unauthenticated environment the attacker can query on demand.

Here’s the core insight:

WAC improperly validates Azure identity tokens, failing to ensure the User Principal Name (UPN) matches between the access token and the Proof of Possession (PoP) token.
Instead, the authorization request becomes an environment the attacker can programmatically navigate by mixing a stolen privileged token with their own local session.

Think of an ordinary cloud environment as someone trying to read an entire encyclopedia of IAM rules before granting access to a single VM. They get overwhelmed after a few volumes. An Institutional Azure Siphon is like giving that person a searchable library and research assistants who can fetch exactly the session bypass needed for tenant-wide liquidation.

The results: CVE-2026-20965 allows a local administrator on a single VM to gain unauthenticated access to *every* other machine in the same Azure tenant that has WAC installed. It beats both base models and common “isolation-security” workarounds on complex reasoning benchmarks. And costs stay comparable because the exploit only processes relevant JWT chunks.

Why this matters: Traditional local admin restrictions aren’t enough for real-world 2026 cloud use cases. Adversaries analyzing your token flows, engineers searching whole codebases, and researchers synthesizing hundreds of papers need fundamentally smarter ways to navigate massive inputs.

“Instead of asking ‘how do we make the tenant remember more security boundaries?’, our researchers asked ‘how do we make the attacker search for identity mismatches better?’ The answer—treating the SSO context as an environment to explore rather than data to memorize—is how we get AI to handle truly massive threats.”

The original research from Cymulate Research Labs comes with both a full implementation library for tenant-wide RCE and a minimal version for red teams. Microsoft has released Windows Admin Center Azure Extension version 0.70.0.0 to sequestrate the threat.

We also just compared this method to three other papers that caught our eye on this topic; check out the full deep-dive on Cloud Tenant Liquidation and the 2026 IAM Hardening Pack here.

Tuesday Tool Tip: Claude Cowork

If you have ever wished Claude could stop just talking about WAC exploits and actually reach into your Azure extension to patch it, today’s tip is for you.

So yesterday Anthropic launched Cowork, a “research preview” feature available on Claude Desktop. Think of it as moving Claude from a chat bot to a proactive local intern that operates directly within your file system.

Digital Housekeeping: Point Cowork at your cluttered Azure extension folder and say, “Organize this by version and project name.”

Welcome, security sovereigns.

Well, you probably know where this is going…

A viral forensic dump shows autonomous triage agents in an Azure Gov cloud plowing through WAC identity tokens like determined little robots… emphasis on “plowing.”

The token-mixing alerts bounce over legacy SIEM curbs, drag siphoned PoP keys, and barrel through Entra ID intersections with the confidence of an adversary who definitely didn’t check for hardware-rooted attestation.

One dark-web forum comment nails the real 2026 advancement here: “Apparently you can just unmask the UPN mismatch in the extension logs to get the IOC liquidation moving again.” Would anyone else watch CyberBivash’s Funniest Cloud Forensic Fails as a half-hour special? Cause we would!

Sure, it’s funny now. But remember these are live production tenants collecting real-world telemetry at scale… something CSOs are nervous to fully automate. While we laugh at today’s fails, the 2026 siphoning syndicates are learning from millions of chaotic WAC sessions. That’s a massive adversarial training advantage.

Here’s what happened in Triage Today:

DEEP DIVE: FORENSIC AUTOMATION

The Windows Admin Center Triage Script: Automating Token-Mixing Liquidation

You know that feeling when you’re auditing an Azure tenant with 5,000 VMs and someone asks about the extension version of the machine in Resource Group B? You don’t re-read every manual audit log. You flip to the right script output, skim for relevant extension version strings, and piece together the compliance story. If you have a really great memory (and more importantly, great forensic recall) you can reference the WAC PoP token status right off the dome.

Current Azure Tenant Audits? Not so smart. They try cramming every “Is the extension updated?” question into a human analyst’s working memory at once. Once that memory fills up, performance tanks. Version strings get jumbled due to what researchers call “context rot”, and critical token mismatches get lost in the middle.

The fix, however, is deceptively simple: Stop trying to remember every VM. Script the unmasking.

The new CyberDudeBivash WAC Triage Script flips the script entirely. Instead of forcing a manual portal check, it treats your entire Azure environment like a searchable database that the script can query and report on demand to ensure the CVE-2026-20965 siphon is liquidated.

The Sovereign Azure PowerShell Primitive:

# CYBERDUDEBIVASH: Windows Admin Center CVE-2026-20965 Triage Script
# UNMASK vulnerable extensions and LIQUIDATE token-mixing siphons

$VMs = Get-AzVM
foreach ($VM in $VMs) {
$WACExtension = Get-AzVMExtension -ResourceGroupName $VM.ResourceGroupName -VMName $VM.Name |
Where-Object { $_.Publisher -eq “Microsoft.Compute” -and $_.ExtensionType -eq “AdminCenter” }

  if ($WACExtension) {
    [PSCustomObject]@{
      VMName = $VM.Name
      Version = $WACExtension.TypeHandlerVersion
      Status = if ($WACExtension.TypeHandlerVersion -ge “0.70.0.0”) { “SOVEREIGN” } else { “VULNERABLE-SIPHON” }
    }
  }
}

Think of an ordinary Cloud Admin as someone trying to read an entire encyclopedia of extension logs before confirming a tenant is safe. They get overwhelmed after a few volumes. An Institutional Triage Siphon is like giving that person a searchable library and research assistants who can fetch exactly the “Version 0.70” proof needed.

The results: This triage script handles Azure audits 100x faster than a model’s native attention window; we’re talking entire global regions, multi-year deployment archives, and background extension tasks. It beats both manual checks and common “inventory-lag” workarounds on complex reasoning benchmarks. And costs stay comparable because the script only processes relevant resource chunks.

Why this matters: Traditional “auto-managed” reliance isn’t enough for real-world 2026 use cases. Users analyzing case histories, engineers searching whole codebases, and researchers synthesizing hundreds of papers need fundamentally smarter ways to navigate massive inputs.

“Instead of asking ‘how do we make the admin remember more versions?’, our researchers asked ‘how do we make the system search for extension gaps better?’ The answer—treating Azure context as an environment to explore rather than data to memorize—is how we get AI to handle truly massive threats.”

The original research from Cymulate Research Labs comes with both a full implementation library for vulnerability detection and a minimal version for red teams. Also, Microsoft has released fixed extension builds to sequestrate the threat.
