Theodora describes her associate as using a packet sniffer to access Jasper's network and spy on his online activities. She says they use a brute force approach to access the network. Packet sniffing has nothing to do with brute force attacks as the data is perpetually changing. Whilst you might use a brute force attack to hack the password to a router or computer, or to gain access via flooding or a similar approach, they are very different processes and actions. You need to gain access to the network first before you can sniff traffic.
