Ok; could you suggest an alternate? Would be handy to have a shorthand to refer to the incident

How you come up with a name is up to you and how you use it. Personally I would go with "July 2022 Shanghai National Police database leak" because I'm not having any conversation where a cute codename would be less confusing.

At work we codename security issues we are working on for Slack channels, etc. We use unrelated names that you could get from a name generator.

not their job. How about you come up with something catchy?

Shanghai'd is already a phrase that means something else, anyways.
