Vulnerability Scanning Hacker Tools

‘Vulnerability Exploitation Scanning Software’ can make the life of a Pentester easy easier.

However, a good Penetration Tester (‘Ethical Hacker’) will never rely solely on their tools. The ‘human’ and the ‘tool’ when combined can have very difficult results. What is often the case in the corporate world is when a Penetration Test is commissioned by the client they might often request that a second Red Team come into the organization to conduct the same test.

The reason for this is not so much to ensure a competitive atmosphere but rather it is done to compare the results of offensive security teams since it is very likely that the teams will be using the same tools and hacking software that we have listed below.

Sn1per has generated a lot of buzz, mostly because it just works great; runs smoothly and is designed to be an efficient tool that enumerates and scans for vulnerabilities. This hacking tool comes in three flavors: a Community Edition and paid versions (Professional and Enterprise).

You can check out their site for more information.

Sn1per, much like Metasploit, is integrated with many other popular hacking tools such as Nmap, THC Hydra, nbtscan, w3af, whois, nikto and of course WPScan. WPScan is particularly important because at the last check 33% of web CRM’s are WordPress.

How Does It Work?

Sn1per works by automating a bunch of processes that collect basic recon on a target domain, (for example executing dorks search parameters, enumerating open ports, scanning for a known web app for vulnerabilities, brute-forcing open servicing – and a lot more).

Much like Nmap, you can set the tool to be noisy or stealth.

We’d absolutely recommend this tool and would advise using it as an initial “what’s what” out there to garner some intel on a target during the initial stages of engagement (pentest).

(We should really place this tool in our Multi-Purpose Tools section!)


Made by the same folks that manage Metasploit (Rapid7) Nexpose is a vulnerability scanner that aims to support the whole vulnerability management lifecycle.

Nipper Studio processes the devices’ native configurations during a network audit and enables users to create various audit reports.

Using traditional methodology for your network audits, such as Agent-based software and Network Scanners or manual Penetration Testing, you could experience various drawbacks, which does not affect Nipper Studio security audit software. These network scanners send large numbers of network probes to a device and can impact performance. Only the exposed vulnerabilities are verified, potentially missing many issues.

Agent-based audit software requires software to be installed on the devices during the network audit. This is not possible for all devices and can introduce additional security vulnerabilities.

Manual Penetration Tests checks individual network devices in detail. However, this is slow, expensive and results in point in time audits of only a sample of devices.

SAINT is a paid product that provides support to the Security Content Automation Protocol specification as an Authenticated vulnerability, unauthenticated vulnerability scanner. There are four steps of a SAINT Scan…

Step 1 is to screen every live system on a network for TCP and UDP services.

Step 2 is for each service that it finds running, it launches a set of probes designed to detect anything that could allow an attacker to gain unauthorized access, create a denial-of-service, or gain sensitive information about the network.

Step 3 is to scan for vulnerabilities and the last step is that when vulnerabilities are detected, the results are categorized in several ways, allowing customers to target the data they find most useful.

Is SAINT Free?

SAINT is used to be an open-source tool but like Nessus but is now a commercial vulnerability scanning tool.

Does SAINT Work on all Operating Systems?

It works on Linux and MAC OS X while other users say that it can also run on the Windows operating system and can scan Windows vulnerabilities.

What are the Typical Uses for SAINT?

SAINT is used to screen every live system on a network for UDP and TCP services. For every service and node that it discovers, it will launch a set of pings and probes designed to detect anything that will allow attackers or hackers to gain unauthorized access, gain sensitive information about the network or create a denial of service (DOS).


What does a vulnerability scanning tool do?

Vulnerability scanning using one of the tools listed in our resource works by inspecting potential points of exploitation on a computer or network to identify security holes that can later be patched by a Cybersecurity Professional.

A vulnerability scanning tool also typically detects and classifies system weaknesses in computers, networks and communications equipment (hardware) and predicts the effectiveness of countermeasures.

Is Nmap a vulnerability scanner?

Nmap doesn’t ship specifically as a vulnerability scanner but the NSE (Engine) is able to execute vulnerability checks. Many vulnerability detection scripts are available to security professionals (mostly Penetration Testers would find them useful).

  1. Hi guys, I’m a little late to the game, but I am really interested in learning more about hacking, both white and blackhat. I have some basic background in writing code in javascript, python, and ruby and have built a few web applications myself (or have been on the team who built the app) I was wondering if you guys could point me in the right direction.. Any advice or tips would be really appreciated. Cheers, David

        1. Takes time, patience, more time, learn skills, learn as much as you can! Learning how to use Hacking Tools and related software is absolutely the key. Maybe spin up a vulnerable box and try to hack it? The satisfaction will be good!
