CLEAN : Apple FBI investigate massive celebrity photo hack

The video tutorial discusses the challenges of data removal, highlighting that data is not truly removed unless new data is registered on the same hardware. It identifies a weakness in a service related to unlimited authentication attempts, contrasting it with smart card limitations. The tutorial also explains how anonymity at the application level can be bypassed by tracking IP addresses with the help of network operators.

What is necessary for data to be considered completely removed from hardware?

• The data is overwritten by new data on the same hardware.

• The data is deleted from the software.

• The data is encrypted.

• The data is moved to a different location.

What was the identified weakness in the service's authentication process?

• It used outdated encryption methods.

• It was too slow to authenticate users.

• It allowed unlimited authentication attempts.

• It required too many authentication attempts.

How does a smart card typically limit authentication attempts?

• By allowing five attempts.

• By allowing three attempts.

• By allowing unlimited attempts.

• By allowing only one attempt.

What can network operators use to trace the real person behind an IP address?

• Device serial number

• User credentials

• Network data

• Application data

At what level is anonymity maintained according to the transcript?

• Application level

• Network level

• User level

• Hardware level
