The vulnerability that led to the WannaCry ransomware infections affected which protocol?

Show Suggested Answer Hide Answer
Suggested Answer: D

A Virtual Private Network (VPN) typically requires two Security Associations (SAs) for a secure communication session. One SA is used for inbound traffic, and the other for outbound traffic.

In the context of IPsec, which is often used to secure VPN connections, these two SAs facilitate the bidirectional secure exchange of packets in a VPN tunnel.

Each SA uniquely defines how traffic should be securely processed, including the encryption and authentication mechanisms. This ensures that data sent in one direction is handled independently from data sent in the opposite direction, maintaining the integrity and confidentiality of both communication streams.

'IPsec Security Associations,' RFC 4301, Security Architecture for the Internet Protocol.

Wait, was the answer 'Samba'? I thought that was a dance move, not a protocol. Guess I need to get my protocols and dance moves straight.

Samba, huh? Isn't that what they play at the beach? Clearly not the right choice for this question.

RPC? Really? I haven't heard of that one before. Guess I need to brush up on my protocol knowledge.

I think the vulnerability that led to WannaCry was related to SMB.

I can't believe I almost picked 'None of these'! That would have been a total rookie mistake.

SMB definitely sounds like the right answer here. WannaCry targeted a vulnerability in the SMB protocol, causing widespread infections.
