Johnny is a member of the hacking group Orpheus1. He is currently working on breaking into the
Department of Defense’s front end Exchange Server. He was able to get into the server, located in
a DMZ, by using an unused service account that had a very weak password that he was able to
guess. Johnny wants to crack the administrator password, but does not have a lot of time to crack
it. He wants to use a tool that already has the LM hashes computed for all possible permutations
of the administrator password.
What tool would be best used to accomplish this?

The FIN flag is set and sent from host A to host B when host A has no more data to transmit
(Closing a TCP connection). This flag releases the connection resources. However, host A can
continue to receive data as long as the SYN sequence numbers of transmitted packets from host
B are lower than the packet segment containing the set FIN flag.

In this type of Man-in-the-Middle attack, packets and authentication tokens are captured using a
sniffer. Once the relevant information is extracted, the tokens are placed back on the network to
gain access.

Leesa is the senior security analyst for a publicly traded company. The IT department recently
rolled out an intranet for company use only with information ranging from training, to holiday
schedules, to human resources data. Leesa wants to make sure the site is not accessible from

resources” somewhere in the webpage.
What Google search will accomplish this?
