Dear,
regarding the Cyber Kill Chain Quiz, the question Q5 is anbiguos.
Would you mind to explain a bit more your point of view?
In the course, the “Delivery” phase is explain like:
The third step of the Cyber Kill Chain is the "Delivery" stage. At this stage, the attacker executes the cyber attack that he prepared for in the preceding phases. This is the stage where the first interaction with the victim happens. For instance, malware is uploaded to the proper environment at this step, and the victim downloads the malware from the uploaded environment to their systems. Malicious content can be conveyed to the victims' devices in various ways during the delivery phase.
while the “Exploitation” phase is defined:
The fourth step of the Cyber Kill Chain is the "Exploitation" stage. The attacker ensures that the malicious content provided to the victim in the previous step gets activated in this stage. During the exploitation step, the process of running the malware transmitted to the victim's device is carried out. The initial operation in the system is performed by the attacker at this stage.
in the light of the above, I believe (might be wrong) that my answer is correct.
Thanks a bunch for your consideration
