Lisa Bock dives into hping3, a command-line packet crafting tool. Hping3 is similar to the ping command and specific flags and options can be set and can craft and send ICMP, UDP or TCP packets to remote hosts. Hping can be used to spoof a source address, and determine firewall rules, with the goal of evading the firewall.

And it can also be used to launch…a denial of service attack.…Here are some options, as you can see,…we can do a standard Ping Scan,…SYN Scan, ACK Scan, Christmas Tree Scan,…or UDP Scan.…And for more options, you should look up the man pages…for Hping three.…But let's take a look.…We're in Kali Linux right now, and I'll open up a terminal…so we can do a simple ping scan using Hping three.…
In our ping scanme.nmap.org…which is a site that allows you to test…and do some pinging and scanning.…And I'll stop that, okay so you can see that,…
This course investigates the scanning tools and techniques used to obtain information from a target system, including specially crafted packets, TCP flags, UDP scans, and ping sweeps. Lisa Bock discusses how hackers can identify live systems via protocols, blueprint a network, and perform a vulnerability scan to find weaknesses. She also introduces some of the tools and techniques that hackers use to counter detection via evasion, concealment, and spoofing. In addition, learn how to reduce the threat of tunneling, a method hackers use to circumvent network security.
Note: Our Ethical Hacking series maps to the 18 parts of the EC-Council Certified Ethical Hacker (CEH) exam (312_50). This course maps to the 03 Scanning Networks domain.
