Banner grabbing is used during the scanning phase to gather information on a system, such as operating system, open ports, and services running, along with Version numbers. Lisa Bock covers banner-grabbing tools and techniques along with countermeasures.
- [Instructor] Part of an ethical hacking exercise…is banner grabbing.…Banner grabbing is obtaining information from a target host…in hopes it will find out more information…such as the operation system running,…open ports and services that are running…along with version numbers.…Within Kali Linux, there are a number of tools.…Netcat and Nmap are very powerful and can do port scanning…and also provide us with information…on the services that are running.…
DMitry or Deepmagic Information Gathering Tool…is also very useful.…And Curl, we can use that to grab a web banner.…Armitage is very powerful.…It will seek out vulnerabilities…and then once they're found…will provide a list of suitable exploits.…Now in this case,…this is the type of output you might see if you run Nmap.…For example, it will tell us…which one of those ports are open…and what is running including the version.…
Now online I found a couple of tools…to illustrate banner grabbing.…Here we can take a look at a browser check.…Now let's just go Scan Now and we'll say Continue…
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: The Ethical Hacking series maps to the 20 parts of the EC-Council Certified Ethical Hacker (CEH) exam (312_50) version 10.
