Introduction As you may know, Compass Security participated in the 2023 edition of the Pwn2Own contest in Toronto and was able to successfully compromise the Synology BC500 camera using a remote code execution vulnerability. If you missed this, head over to the blog post here https://blog.compass-security.com/2024/03/pwn2own-toronto-2023-part-1-how-it-all-started/ Unfortunately, the same vulnerability was also identified by other

With millions of professionals voluntarily sharing details about their careers, connections, personal achievements, or keeping up to date with what is happening in their professional sphere, the famous networking platform is not to be underestimated when it comes to OSINT.

Renovate is an OSS CLI/bot that updates your software dependencies automatically. It is usually integrated into the CI/CD process and runs on a schedule. It will create a Pull Request / Merge Request (PR/MR) to your repository with dependency updates. It can optionally auto-merge them. If you host it for several repositories or an organization, it

Depending on the customer’s preference, possible initial access vectors in our red teaming exercises typically include deployment of dropboxes, (device code) phishing or a stolen portable device. The latter is usually a Windows laptop protected by BitLocker for full disk encryption without pre-boot authentication i.e. without a configured PIN or an additional key file. While

TL;DR: PowerShell tool to enumerate Entra ID objects, assignments and identify highly privileged objects or risky configurations. https://github.com/CompassSecurity/EntraFalcon Entra ID environments can contain thousands of objects – users, groups, service principals, and more – each with unique properties and complex relationships. While manual reviews through the Entra portal might be feasible in smaller environments, they

As a pentester you are sometimes thrown into projects where you have no idea where you are going to end up.

In the previous posts of this series, we looked at different ways to bypass web filters, such as Host header spoofing and domain fronting. As we’ve learned, these techniques can be detected by proxies employing TLS inspection, by checking whether the hostname in the SNI matches the one in the HTTP Host header. If they

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.
