Algolia got impacted too, apparently their Salt masters were opened to the whole internet: https://blog.algolia.com/salt-incident-may-3rd-2020-retrospe...
> I'm sad to report that we discovered today that CT Log 2's key used to sign SCTs was compromised last night at 7 pm via the Salt vulnerability.
Several other "high-profile" sites have been compromised as well, including LineageOS and Ghost. I expect we'll hear of many more in the next few days.
