BloodHound is the way to go to for finding attack paths in an Active Directory (AD) environment. However, it is not always clear how the data is gathered without looking at the code of SharpHound, the data ingestor for BloodHound.

During a DFIR (Digital Forensics and Incident Response) Case, we encountered an ESXi Hypervisor that was encrypted by the Ransomware LockBit 2.0. Suspicious SSH logons on the Hypervisor originated from an End-of-Life VPN Appliance (SonicWall SRA 4600). It turns out, this was the initial entry point for the Ransomware attack. Follow us into the forensics […]
Agile software development models have become the de-facto standard. They are taught at universities and implemented in practice as far as possible. Anyone who doesn’t develop software using agile processes is on the verge, and already tilting towards that. At least that is how it seems. Consequently, the question is not whether the integration of […]
The end of the year is a good time to sit back and reflect for a moment on the past year. So let us take a look at the ten most common ways how I got Domain Admin privileges in our Active Directory penetration tests in 2021.
On October 12th the Swiss Cyber Storm conference took place in the Kursaal in Bern. Several Compass analysts attended the conference, our security analyst Yves Bieri held a talk and we also had a booth. The conference was great fun, finally a in-person conference with many interesting talks. This blog post wraps up some talks we attended.
Sometimes one goes deep down the rabbit hole, only to notice later that what we were looking for is just under one’s nose.
This is the story of a digital forensic analysis on a Linux system running docker containers. Our customer was informed by a network provider that one of his system was actively attacking other systems on the Internet. The system responsible for the attacks was identified and shut down.
Our DFIR hotline responded to the call and we were provided with a disk image (VMDK) to perform a digital forensic analysis.
ArcGIS [1] is a family of software providing geographic information system services. While testing a customer’s ArcGIS architecture we came across a SAML login flow. In this blogpost we show how we found and exploited an AES-CBC padding oracle in this flow.
During a customer project, we could bypass the biometric authentication mechanism of Ionic Identity Vault on Android, because the Android KeyStore entry does not require any authentication. This post shows how this was done and how it can be exploited.
