Task 2: Perform Host Discovery using Angry IP Scanner

Angry IP Scanner is an open-source and cross-platform network scanner designed to scan IP addresses as well as ports.

In the IP Range fields, type the IP range as 10.10.10.0 to 10.10.10.255 and click
the Preferences icon beside the IP Range menu, as shown in the screenshot.
The Preferences window appears. In the Scanning tab, under the Pinging section, 
select the Pinging method as Combined UDP+TCP from the drop-down list.
Now, switch to the Display tab. Under the Display in the results list section, 
select the Alive hosts (responding to pings) only radio button and click OK.
IP Range - Angry IP Scanner window, click the Start
Note the total number of Hosts alive (here, 6) and click Close.
results of the scan appear in the IP Range - Angry IP Scanner window.


Angry IP Scanner is an open-source and cross-platform network scanner designed to scan IP addresses as well as ports. It simply pings each IP address to check if it is alive; then, optionally by resolving its hostname, determines the MAC address, scans ports, etc. The amount of gathered data about each host can be extended with plugins.

Here, we will use the Angry IP Scanner tool to discover the active hosts in the target network.

  1. Click Windows 10 to switch to the Windows 10 machine, navigate to D:\CEH-Tools\CEHv11 Module 03 Scanning Networks\Ping Sweep Tools\Angry IP Scanner and double-click ipscan-3.7.2-setup.exe.

    If User Account Control pop-up appears, click Yes.

  4. Angry IP Scanner starts, and a Getting Started window pops up. Click Next, follow the wizard, and click Close.

    Open File - Security Warning window appears, click Run.

  8. Now, switch to the Display tab. Under the Display in the results list section, select the Alive hosts (responding to pings) only radio button and click OK.

    Screenshot

  9. In the IP Range - Angry IP Scanner window, click the Start button to start scanning the IP range that you entered.

    Screenshot

  10. Angry IP Scanner starts scanning the IP range and begins to list out the alive hosts found. Check the progress bar on the bottom-right corner to see the progress of the scanning.

  11. After the scanning is completed, a Scan Statistics pop-up appears. Note the total number of Hosts alive (here, 6) and click Close.

    Screenshot

  12. The results of the scan appear in the IP Range - Angry IP Scanner window. You can see all active IP addresses with their hostnames listed in the main window.

    Screenshot

  13. This concludes the demonstration of discovering alive hosts in the target range of IP addresses using various Angry IP Scanner.

  14. You can also use other ping sweep tools such as SolarWinds Engineer’s Toolset (https://www.solarwinds.com), NetScanTools Pro (https://www.netscantools.com), Colasoft Ping Tool (https://www.colasoft.com), Visual Ping Tester (http://www.pingtester.net), and OpUtils (https://www.manageengine.com) to discover active hosts in the target network.

  15. Close all open windows and document all the acquired information.

Lab 1: Perform S3 Bucket Enumeration using Various S3 Bucket Enumeration Tools Lab Scenario As an ethical hacker, you must try to obtain as much information as possible about the target cloud environment using various enumeration tools. This lab will demonstrate various S3 bucket enumeration tools that can help you in extracting the list of publicly available S3 buckets. Lab Objectives Enumerate S3 buckets using lazys3 Enumerate S3 buckets using S3Scanner Overview of Enumeration Tools Enumeration tools are used to collect detailed information about target systems to exploit them. Information collected by S3 enumeration tools consists of a list of misconfigured S3 buckets that are available publicly. Attackers can exploit these buckets to gain unauthorized access to them. Moreover, they can modify, delete, and exfiltrate the bucket content. Task 1: Enumerate S3 Buckets using lazys3 lazys3 is a Ruby script tool that is used to brute-force AWS S3 buckets using different permutations. This...

  Task 2: Perform OS Discovery using Nmap Script Engine (NSE) Module 03: Scanning Networks Lab 3: Perform OS Discovery Task 2: Perform OS Discovery using Nmap Script Engine (NSE) open zenmap nmap -A [Target IP Address]   = -A: to perform an aggressive scan. nmap -O [Target IP Address]   = -O: performs the OS discovery. nmap --script smb-os-discovery.nse [Target IP Address]   = --script: specifies the customized script and smb-os-discovery.nse: attempts to determine the OS, computer name, domain, workgroup, and current time over the SMB protocol (ports 445 or 139). end Nmap, along with Nmap Script Engine (NSE), can extract considerable valuable information from the target system. In addition to Nmap commands, NSE provides scripts that reveal all sorts of useful information from the target system. Using NSE, you may obtain information such as OS, computer name, domain name, forest name, NetBIOS computer name, NetBIOS domain name, workgroup, system time o...
