What is a Hack-Lab? Compass Security provides a monthly playful occasion for the security analysts to get-together and try to hack new devices, dive into current technologies and share their skills with their fellows.

ASP.NET Core is a open-source and cross-platform framework for building modern cloud based internet connected applications, such as web apps, IoT apps and mobile backends. ASP.NET Core apps can run on .NET Core or on the full .NET Framework. It was architected to provide an optimized development framework for apps that are deployed to the cloud […]
About a year ago, the Burp extension SAML Raider [0] was released as a result of a bachelor thesis [1] in collaboration with Compass Security. This Burp extension automates most of the steps, which are necessary to test a SAML single sign-on process and perform according attacks. With SAML Raider, an authentication bypass vulnerability in a Service […]
Three months ago I tested the web interface of the Netgear WNR1000v4 router for some typical vulnerabilities. When playing around with the application by forcefully calling different URLs in contexts it was not meant for, I got some strange, but interesting behaviour. I accessed different URLs and then switched back to the root web directory […]
Two months ago, we wrote about SAML Raider, a Burp extension which allows automating SAML attacks based on manipulations of the intercepted security assertion. Using this tool, we were able to identify a severe vulnerability in the service provider (SP) implementation of AdNovum‘s nevisAuth. The following conditions make exploitation possible: SAML POST-Binding is used, i.e. […]
During a SharePoint 2013 penetration test I performed last November, I noticed that a dynamically constructed JavaScript constantly fetched content or redirected me to the requested pages. Using a variation of the double-slash trick we exploited in the past, I misused this functionality in order to perform a DOM based open redirection attack. Every SharePoint […]
Ein Hintegrundartikel zur SRF Einstein Sendung vom Donnerstag, 3. September 2015 um 21:00 Uhr zum Thema “Cybercrime, wie sicher ist das Know-how der Schweiz”. (Trailer online) In diesem Artikel zeigen wir Ihnen die Vorgehensweisen von Angreifern auf, die versuchen unerlaubten Zugriff auf fremde Systeme zu erlangen — beispielsweise im Netzwerk eines KMUs. Schematisch sind diese Vorgehensweisen […]
At our reoccurring Hacklab days, we at Compass get the chance to hack some stuff of our own choice together for a day. For example playing with GSM in an attempt to send fake SMS or eavesdrop on voice data, comparing Encase capabilities to Unix command line forensic tools or cloning door entry badges in […]
Der von Microsoft publizierte “out-of-band” Patch MS14-068 [1] (Vulnerability in Kerberos Could Allow Elevation of Privilege – 3011780) behebt eine Schwachstelle in Kerberos, welche es einem normalen Benutzer erlaubt, administrative Privilegien in der Windows Domäne zu erlangen. Die ersten öffentlichen Artikel [2] mutmassten, dass die Kerberos Services den CRC32 Algorithmus als gütlige Signatur auf Tickets […]
