Example Wireshark packet analysis used to find unencrypted information stored in network packets.
Example hexeditor used to analyse file contents and find missing strings and incorrectly formatted files used in an attempt to masquerade.
Example Burpsuite packet capture, modification of cookies to login to a unsecured site.
Example use of Ghidra to reverse engineer the binary of a program.
CROW is a research group that focuses on six major themes: Provenance, User-Centricity, Visualisation, Economics, Hardware, and Tools & Datasets; to address the diminishing effectiveness of traditional cyber security approaches.
