What is a Wireless Replay Attack?

• An attack where an attacker intercepts a message on a secure communications channel, manipulates (or delays it), then sends it to the receiver without their knowledge that it was changed or delayed.

• An attack where an attacker intercepts a phone call on a secure communications channel and decrypts it to store in a database

• An attack where an attacker passively monitors a message on a secure communications channel.

• An attack where an attacker intercepts a message on a secure communications channel, and stores the message in a database

How is a Wireless Replay Attack possible?

• An attacker gets access to the operating system

• An attacker gets access to the firewall

• An attacker gets access to secure communications channel

• An attacker gets access to encrypted files

You can prevent a Wireless Replay attack by using strong hashing.

• True

• False

You can prevent a Wireless Replay attack by using strong encryption.

• True

• False

How can a timestamp help prevent replay attacks?

• Use timestamps for only important messages. If the same timestamp is seen again by the receiver, discard the message.

• Use timestamps for each messagE) If a different timestamp is seen by the receiver, discard the message.

• Timestamps do not help with replay attacks. If the same timestamp is seen again by the receiver, keep the message.

• Use timestamps for each messagE) If the same timestamp is seen again by the receiver, discard the message.

How can a one-time password (or nonce) help prevent replay attacks?

• Use a one-time password for each messagE) If the same password is seen again by the receiver, discard the message.

• Use a one-time password for very important messages only. If the same password is seen again by the receiver, discard the message.

• One time passwords do not help with replay attacks. If the same password is seen again by the receiver, accept the message.

• Use a one-time password for each messagE) If a different password is seen by the receiver, discard the message.

What type of attack is a wireless replay attack?

• Phishing attack

• Man-in-the-middle attack

• SQL Injection

• XSS attack

Rather than collect thousands of IV packets, what type of replay attack can be used?

• ARP request

• ATR request

• ART request

• APT request
