Don’t Look at This! IT’S A SECRET!

To continue the discussion about secrets after perusing this excellent report by GitGuardian—last time I went a little nuts about the number of secrets exposed in IT folks’ personal repositories. And it is a lot. I mean a lot of secrets. But you know what is scarier than, “A lot of secrets are leaked in personal repositories of people rushing to get this week’s sprint in”? The fact that 30,000 secrets were leaked via corporate public repositories in 2020. That’s thirty thousand.

This is not some poor DevOps person in a rush to meet deadlines and with no real security support for personal repositories who dropped some secrets into a public personal repository.

This is a system set up by your organization that should have security awareness, should be getting scanned regularly and that should never be a source of information for hackers. Instead, it is a source of information, perhaps even critical information, that hackers can easily snag. Because there are secrets in this public repository.

The first step to avoiding this problem is to acknowledge that IT can’t serve every need, and ask business units (BUs) to come forward with any apps they’ve developed behind your back so that (non-invasive) security can be applied to those apps.

You’ll either get some apps, or people won’t trust you and you won’t get any. In the latter case, truthfully explain about secrets hiding in public repositories and ask them to validate their own. It’s the best you can do if people won’t share what they’ve done, and there are still people out there that think IT involvement is a huge impediment to their software. ::Shrug:: As long as you can get them to check their apps for vulnerabilities, it shouldn’t matter too much. But I’m more concerned about getting the secrets, so I won’t debate the centralized-versus-distributed-app philosophies in this blog beyond saying, For secrets, if you can get them to scan/clean them up, the question of who is managing the app and the process isn’t very important.

I’m still shaking my head—30,000! That is more than 100 secrets checked into public, corporate repositories each day (on average, of course). Please, go through your org, make sure you are not contributing to this total. That is wild; even if you account for the fact that if an app has one secret out there, it probably has multiple; even assuming each vulnerable app had four, that’s still 7,500 apps exposing secrets in the most preventable way possible.

So, if you’re not certain about your public repos, go get certain. The ROI on “a few minutes for a scan, or a couple hours for a person to search for them” versus “our AWS secret was compromised,” or, “our API key was discovered and abused,” is pretty high.

And keep rocking it. The sheer volume of apps out there is part of the shared-secrets problem, as is the growth in use of secrets as automation and DevOps have taken over. But you’ve got the solution, just make sure they’re not hanging out there in a public repo. And then go back to doing what keeps the business alive.
