> Even though we believed, and later confirmed, the attacker had limited access, we undertook a comprehensive effort to rotate every production credential (more than 5,000 individual credentials), physically segment test and staging systems, performed forensic triages on 4,893 systems, reimaged and rebooted every machine in our global network including all the systems the threat actor accessed and all Atlassian products (Jira, Confluence, and Bitbucket).
> The threat actor also attempted to access a console server in our new, and not yet in production, data center in São Paulo. All attempts to gain access were unsuccessful. To ensure these systems are 100% secure, equipment in the Brazil data center was returned to the manufacturers. The manufacturers’ forensic teams examined all of our systems to ensure that no access or persistence was gained. Nothing was found, but we replaced the hardware anyway.
They didn't have to go this far. It would have been really easy not to. But they did and I think that's worthy of kudos.
