Even those attackers who are deploying more targeted, advanced attacks against a specific industry or organization will reuse the same techniques and exploit code in targeted attacks against similar organizations in the same industry. Another tool in the attacker’s arsenal is that they are highly adept at sharing information with each other. Why wouldn’t defenders likewise collaborate on the source, tools and techniques used for these attacks and reap the tremendous benefits of threat sharing? Not to mention that such collaboration among defenders can also increase the costs associated with executing these attacks.
