The following excerpt is taken from a honeyput log. The log captures activities across three days. There are several intrusion attempts; however, a few are successful. Study the log given below and answer the following question:

(Note: The objective of this questions is to test whether the student has learnt about passive OS fingerprinting (which should tell them the OS from log captures): can they tell a SQL injection attack signature; can they infer if a user ID has been created by an attacker and whether they can read plain source destination entries from log entries.)

What can you infer from the above log?

A.
The system is a windows system which is being scanned unsuccessfully.

B.
The system is a web application server compromised through SQL injection.

C.
The system has been compromised and backdoored by the attacker.

D.
The actual IP of the successful attacker is 24.9.255.53.
