This tweet mentions a presentation or slides for a talk titled 'ToolShell Patch Bypass and the AI That Might Have Seen It Coming' at NDC Conferences Manchester 2025. It also mentions some WAF (Web Application Firewall) bypass techniques or workarounds as a bonus. However, the tweet does not provide specific technical details or payloads related to the WAF bypass. The talk seems to be related to application security and possibly SharePoint, given the hashtags #AppSec, #SharePoint, and #TolShell.

Since the tweet does not provide specific details about the WAF vendor, type of vulnerability affected, or exact payloads used for bypass, it's difficult to analyze the bypass in detail. This content likely refers to a presentation where these details would be revealed.
