No matter we are talking about Information Security, or cyber security or IT security... I always hear first about "the moth" being the first security threat. But I don't believe it is when talking about cyber security.
I believe that the infamous MARK II moth is a computer related incident, and it is even a security incident which affected the integrity of the code MARK II was running. But I don't think we can consider this a "cyber" security menace.
I have also read (and I am more inclined toward this thought) that, in fact, the famous "blue boxes" might be the real first cyber security incidents.
Others think that the first cyber security incident was the first virus ever in ARPANET: "The Creeper", but I believe this is more a concept application than a real menace, so, here is my question,
Which event is consider the first cyber security incident? and,
Is there any other than, due to its importance or relevance could be considered than the first real one?
