Refer to the exhibit.

Which security issue is possibly indicated by this traffic capture?

Show Suggested Answer Hide Answer
Suggested Answer: C

DNS tunneling is a technique that abuses the DNS protocol to tunnel data or commands between a compromised host and an attacker's server.DNS tunneling can be used to establish a command and control channel, which allows the attacker to remotely control the malware or exfiltrate data from the infected host1

The traffic capture in the exhibit shows some signs of DNS tunneling. The source IP address is 10.1.7.2, which is likely an internal host behind a firewall. The destination IP address is 8.8.8.8, which is a public DNS resolver. The DNS queries are for subdomains of badsite.com, which is likely a malicious domain registered by the attacker. The subdomains have long and random names, such as 0x2a0x2a0x2a0x2a0x2a0x2a0x2a0x2a.badsite.com, which could be used to encode data or commands.The DNS responses have large sizes, such as 512 bytes, which could be used to carry data or commands back to the host2

I think it's a port scan on the subnet.

I believe it's more likely to be ARP poisoning or man-in-the-middle attack.

But it could also be a command and control channel with DNS tunneling.

I agree, it could be an unauthorized DNS server.
