Creating SYN Port Scan Manually with Scapy HD

Author: Jeremy Druin Twitter: @webpwnized This video covers creating a port scan by building the packets manually with Scapy. Scapy makes packet crafting relatively easy compared to the extensive control the operator has over the construction of the packets. Nearly any attribute of the packets can be carefully crafted by the user and responses to sent packets can be captured for examination. In the video, an IP packet is crafted and set aside to be used repeatedly. A TCP packet is created for port 80 on the target, which is known to be open. The packet is sent and the port is confirmed open. To test a closed port, the TCP packet is set to port 81 which is a port thought to be closed. The packet is sent and the port status is confirmed. Users new to scapy, tcpdump, and nmap will receive brief tutorials in the video on getting started. Videos on this channel are annouced at the @webpwnized on Twitter.
