It was great to get back out on the mound for the first time this year against @Ramblrbaseball and throw 3 scoreless innings for @WildkitBaseball. Looking forward to a competitive season.

@mattjay @Matt_Gerlach @jeremiahg @JGamblin @mroytman Lots of that found here cisco.com/c/dam/en/us/pr…
Also a lot of exploited vulns that never make their way on to the KEV. It cuts both ways.

@Matt_Gerlach @jeremiahg @JGamblin Yeah I gave a talk with @ebellis called CVSS sucks using Kenna and whitehat data. @mroytman did a bunch of that research too.

If you’re fixing things in order of CVSS score, you’re doing yourself a disservice:
Jeremiah Grossman@jeremiahg
Total CVEs: 240,830 Total KEVs 1,218 0.5% of CVEs have been seen exploited in the wild historically. I've also asked several cyber-insurance carriers if they could share with me the CVEs that resulted in claims. Answer, less than 200 per year.

In the fourteen days since Kernel.org became a CNA, they have published 367 CVEs, or just over 21% of all CVEs during that time frame. It is unclear if this is just them clearing their backlog or if we should expect the 20% increase to continue.
