A cyber security system, the cyber security system comprising a processing circuitry configured to: obtain: (a) an attack-vector scenario, the attack-vector scenario comprising a sequence of cyber tactics, and (b) information about actual sequences of machine language instructions that executed on the one or more processors: identify, based on the information, the cyber techniques that occurred on the organizational network by matching the actual sequences of machine language instructions with the at least one sequence of machine language instructions associated with the cyber techniques, and alert a user of the cyber security system of a potential cyber-attack upon determining that each of the cyber tactics forming the attack vector scenario, is associated with at least one of the implemented cyber techniques.
