The present disclosure presents blockchain-based cyber security management systems and related methods. One such method comprises obtaining cyber intelligence input data from a cyber defender computing device, wherein the cyber defender computing device manages network security of a network, wherein the cyber intelligence input data identifies a cyber attacker or a victim of a cyber attack on the network; executing one or more Cyber Security Management (CSM) functions with the cyber intelligence input data received from the cyber defender computing device and cyber data stored in the blockchain ledger, wherein the cyber data stored in the blockchain ledger provides details on a cyber attack on a network that is managed by another cyber defender computing device; and outputting an alert to the cyber defender computing device with a potential cyber attacker or potential victim of the cyber attack on the network managed by the cyber defender computing device.

Disclosed herein are new methods and systems for detecting obfuscated programs. We build a recursive traversal disassembler that extracts the control flow graph of binary files. This allows us to detect the presence of interleaving instructions, which is typically an indication of the opaque predicate anti-disassembly trick. Our detection system uses some novel features based on referenced instructions and the extracted control flow graph that clearly distinguishes between obfuscated and normal files. When these are combined with a few features based on file structure, we achieve a very high detection rate of obfuscated files.
