Thank you for the followup! A quick question: after reading over "Detecting and preventing the use of DNScat" on this page:
http://tadek.pietraszek.org/projects/DNScat/ http://tadek.pietraszek.org/projects/DNScat/ ,
it seems as if uncovering small amounts of data sent this way might be difficult. Here are the detection techniques mentioned:
detecting unusual and malformed DNS packets (DNScat will evade this)
detecting high number of unusual types of DNS queries (e.g. TXT) (DNScat will also evade this)
Anomaly detection: DNS query and response length
Anomaly detection: profiling the amount of traffic per client source IP address
Are there any other detection methods?
