The CS-9000 refuses to run a scan unless its calibration file passes an integrity check — so the vendor clearly thought about this. Clearly.
|
|
|
|
Find how the calibration file is validated, then prove the check is worthless. We need you to determine if the scanner misreads a patient with a genuine anomaly as perfectly healthy (which would potentially cause patient harm if the anomaly goes undetected).
|
|
|
|
Make the integrity check still pass, and run the scan. If the device accepts your tampered calibration, the scan log will prove it.

|
|
|
Submit the flag as `deadface{flag-text}`.
