I'm trying to review a .pcap of about 900 packets related to a school assignment in which the "suspect" machine probed and attempted to gain access to the "target". I see many packets in which the suspect tried to GET several files, all of which have the same name, but different file extensions. The target machine responded with "404 Not Found" messages. Later, the suspect tried to PUT and POST and HEAD files, also to no avail. Can anyone tell me whether or not these packets are part of an automated exploit being conducted by the "suspect"? Thanks, a sample of some of the packets is shown below:
