[SELL] Microsoft 365 Core Infrastructure Pre-Auth SSRF / Initial Access 0-Day

Greetings, Everyone.
As promised after the Visa configuration exposure in June, the next target is fully operational. Microsoft M365 perimeter security is officially dead.
We are auctioning an unpatched, active Pre-Auth 0-Click Initial Access targeting the core global routing infrastructure of Microsoft 365.
[ Technical Proof ]
Direct network access to Exchange Online internal core production hosts (*.PROD.OUTLOOK.COM) is completely isolated from the internet (Zero public DNS records, curl status 000).
However, using our protocol-level desynchronization vector, we successfully forged an internal network bridge via their custom gateway layer.
[ Updated Live Telemetry Intercept - OWA Application Execution ]
Our protocol desynchronization no longer just triggers gateway errors. We have successfully forced the internal Exchange infrastructure to process active user-facing applications and generate core system cookies:


HTTP/1.1 302 Found
X-CalculatedBETarget: TP3P295MB0169.TWNP295.PROD.OUTLOOK.COM
X-ResponseOrigin: OwaNetCore
X-OWA-ResultType: Redirect
Location: https://127.0.0.1/mail/
Set-Cookie: ClientId=9C1D820516E44EDDBED29972C18E3E46; path=/; secure;
Set-Cookie: X-OWA-RedirectHistory=Apr7_fABNX-xohDY3gg; httponly

Verification: Internal state changes detected. Active OwaNetCore session identification keys (ClientId) are directly generated and exposed without authentication. Microsoft Perimeter security is formally compromised
[ Capabilities & Weaponization ]
  • Perimeter Bypass: Complete network segmentation failure. Bypass all Microsoft Edge WAF and Cloudflare rules.
  • 0-Click Response Hijacking: Confirmed capability to intercept, cross-contaminate, and hijack live remote HTTP data streams of other legitimate users. Mass account takeover (ATO) without user interaction.
  • Verified Scope: Global multi-region infrastructure breakdown (nam, eur, jpn, loki.delve).
  • Limitations: Cache Poisoning is non-functional due to strict backend Cache-Control: no-store / private headers. We sell real impact, not fairytales.
[ Transaction ]
  • Starting Bid: $1,000,000 USD (in Monero/XMR).
  • Buy It Now: $2,500,000 USD.
  • Verification: Live test is available via forum Admin on any clean tenant provided by the buyer.
  • Escrow: Mandatory. Forum Admin only.
Do not PM if you don't have the funds. Time wasters will be ignored
