Just received an email out of the blue from: HAOBAO (Confluence) <confluence@ecosystem.atlassian.net>
I can't find a reference to HAOBAO at Atlassian, and googling the name points to the HaoBao North Korean Bitcoin-Stealing Phishing Campaign
This has all the markings of a phishing attack - has Atlassian suffered a security breach?

"HaoBao" – North Korean Bitcoin-Stealing Phishing Campaign
