Question

What kind of security risk is a rolljam attack?

O a connected vehicle risk
O an Over-the-air access risk
O a remote access risk
O a physical access risk

Answer 1

A rolljam attack is an Over-the-air access risk that allows unauthorized access to connected vehicles using intercepted and replayed wireless signals from keyless entry systems.

Step-by-step explanation:

A rolljam attack is a type of security risk that falls under the category of an Over-the-air access risk. It is a method used to intercept and replay wireless signals from keyless entry systems, typically used in cars. By doing so, attackers can gain unauthorized access to the vehicle without physical contact or the need for a key.

During a rolljam attack, the attacker initially jams the signal between the victim's key fob and the vehicle. The victim then assumes that the vehicle is locked and walks away. However, the attacker captures the blocked signal, preventing the victim's key fob from receiving the confirmation signal that the vehicle is locked. This allows the attacker to use the jammed signal at a later time to unlock the vehicle and potentially steal it.

Therefore, the rolljam attack poses a significant security risk in terms of remote access to connected vehicles, as it exploits vulnerabilities in the wireless communication between key fobs and vehicles.
