Kind: security · Impact: high

## In brief

- Attackers stole central university login passwords for everyone registered with TUM's myTUM portal.
- An admin's stolen credentials were then used to attack a second system.
- TUM restored access to its TUMonline campus management system.

## Why it matters

Anyone with a TUM account should assume their central login password was exposed. Reusing that password elsewhere puts other services at risk.
