Maybe not WHAT but HOW
In theory, the idea of sharing threat intel makes all the sense in the world. As you touched on, the problem in cybersecurity is that you're talking about anonymous adversaries that are constantly changing. While it is important to know file hashes, IPs and some email addresses to block, that system is based on limited data and not exact. Additionally, threats are constantly morphing and changing, so by the time you've identified one, it has already changed. Furthermore, if the bad guys are getting the same threat feed as everyone else, they'll be able to change their attacks in real-time and will see whether they're getting caught -- it's like giving them a real-time tool to check whether their attacks are able to bypass detection systems.

Perhaps the issue isn't WHAT companies are willing to share, but HOW they're willing to share it. For example:


  • What if threat feeds were only machine-to-machine accessible? For instance, if the threat intel was shared in a machine readable format to a SIEM, then only those companies that have detection systems could use that information. It's unlikely that a scammer is going to buy an expensive system to check their work. And if we're talking about systems instead of people, the question then becomes: how do these systems share the information back?
  • What if we could de-couple the organization from the threat, and there was no way to associate the two? Maybe then companies wouldn't have an issue with a system reporting findings back to the mother ship.
  • What if opt-in isn't the right way to go about information sharing? When companies need to opt in to share data, overabundance of caution may get the best of them. On the other hand, if they're already sharing information (albeit anonymously), would that change their mindset?
