Refactored Handle Detection We have completely refactored THOR's malicious Handle detection. We now allow the use of regular expressions and combined all types in a single signature file named "malicious-handles.dat". Users can provide custom indicators by placing a...
We've made a short video demo to showcase the new THOR 10 feature called "THOR Remote", which allows you to perform compromise assessment scans on multiple remote systems - no agent or scripting required.
We are working on a THOR scanner version that brings our well-known compromise assessments and thousands of YARA rules to IBM's AIX®. Subscribe here to get noticed once beta testing and a stable version is available. * no advertisements - just two emails, one for the...
THOR 10 Fusion has arrived. It replaces our successful scanners THOR 8 and SPARK and combines the best of both worlds. It is a completely new code base that features all modules of our 4 year old compromise assessment flagship THOR 8 and the speed and extra features...

People often ask me if they still need our host based scanner THOR now that they have bought a network appliance that already checks all content that goes into and leaves their network. I normally answer that it is not a question of one solution versus another, but a...
Today most security teams have access to a lot of different information sources. On the one hand they collect log data from different sources and try to correlate them in a useful way in so-called SIEM systems. On the other hand they receive threat information from...
