Some sites picked up the Microsoft 365 Copilot penetration test that allegedly proved how Copilot can extract sensitive data from SharePoint Online. When you look at the test, it depends on three major assumptions: that an attacker compromises a tenant, poor tenant management, and failure to deploy available tools. Other issues, like users uploading SharePoint and OneDrive files to process on ChatGPT, are more of a priority for tenant administrators.| Office 365 for IT Pros
An article by a company specializing in penetration tests raised some questions about how attackers might use Copilot for Microsoft 365 to retrieve data. The article is an interesting read and reveals how Copilot can reveal data in password protected Excel worksheets. However, many of the issues raised can be controlled by applying available controls, and the biggest worry is lhow the account being used to run Copilot came to be compromised!| Office 365 for IT Pros

The last two blog posts in this series were about SNI spoofing and Host header spoofing. We also learned that the latter is addressed by some vendors with a technique called “Domain Fronting Detection”. But what exactly is domain fronting? This will be explained in this blog post.| blog.compass-security.com
In the last post about bypassing web filters, I discussed how SNI spoofing works and how this can also be prevented by web filters. This post is about another bypass technique called Host Header spoofing.| blog.compass-security.com

Testing a website is usually considered just another day at work, Burp Suite is usually the tool of our choice for automating some of the scans that apply in this field. Assessing the authenticated part of the site is also common, and since Burp can be used as an HTTP proxy, it can capture our session tokens (usually HTTP cookies) and perform scans just like we’d do as humans. This token is usually remain unchanged over the time of the session, and the session itself is kept alive by the sc...| Silent Signal Techblog
