New paper shows feasibility of covert channels in hash chains

Our new paper (published in MDPI Appl. Sci., open access) uses the Random Value pattern to realize a plausibly deniable covert channels in one-time passwords based on hash chains.

Hands-on tool for Covert Channel Patterns Detection now available!

The tool NeFiAS (Network Forensic & Anomaly Detection System) is an accessible hands-on tool for network covert channel detection. I just made the code of NeFiAS public. I also attached a documentation. Have fun with it!
