This tool runs an attack based on simply requesting the database contents and checking for singling out. This is probably the simplest attack, and works against pseudonymization, but not more sophisticated anonymization methods. In essence, the attack does a ‘SELECT *’ against the database and assumes that each returned row singles out a user. The tool is implemented in the python code dumbList_SingOut.py, found in the repo https://github.com/gda-score/attacks.
