CLEAN : Apple FBI investigate massive celebrity photo hack

The video tutorial discusses the challenges of data removal, highlighting that data may not be completely erased unless new data overwrites it. It identifies a service vulnerability related to unlimited authentication attempts, contrasting it with the typical smart card limit. The tutorial also covers network anonymity, explaining that while applications may appear anonymous, operators can trace IP addresses to identify users.

Under what condition can data be considered completely removed from a system?

• When the user logs out of the system

• When the system is rebooted

• When new data is registered in the same hardware

• When it is deleted from the application interface

What was the security issue with the service mentioned in the video?

• It blocked users after three failed attempts

• It allowed unlimited authentication attempts

• It used outdated encryption methods

• It required a password change every week

How do smart cards typically handle authentication attempts?

• They use a one-time password

• They limit attempts to three

• They require biometric verification

• They allow unlimited attempts

What can network operators do to trace anonymous requests?

• Change the IP address

• Identify the IP address behind the request

• Encrypt the data packets

• Block the request at the firewall

Why is it possible to find the real person behind an anonymous request?

• Because the system uses facial recognition

• Because network operators can trace IP addresses

• Because the application logs all user actions

• Because the user must provide personal information
