After this apparently innocent Google search, the hackers invade the vulnerable sites with the help of a specific program. That program is indeed very simple to find (of course, we blurred the images and masked the illustration) and even has various YouTube tutorials:
How to Find a vulnerable website
Used to find vulnerabilities in database management systems. Databases are the backbone of any system storing sensitive information. Vulnerability scanning is performed on database systems to prevent attacks like SQL Injection.
Vulnerability scanning tools allow for the detection of vulnerabilities in applications using many ways. Code analysis vulnerability tools analyze coding bugs. Audit vulnerability tools can find well-known rootkits, backdoor, and trojans.
Netsparker is another web application vulnerability tool with an automation feature available to find vulnerabilities. This tool is also capable of finding vulnerabilities in thousands of web applications within a few hours.Although it is a paid enterprise-level vulnerability tool, it has many advanced features. It has crawling technology that finds vulnerabilities by crawling into the application. Netsparker can describe and suggest mitigation techniques for vulnerabilities found. Also, security solutions for advanced vulnerability assessment are available.
OpenVAS is a powerful vulnerability scanning tool that supports large-scale scans which are suitable for organizations. You can use this tool for finding vulnerabilities not only in the web application or web servers but also in databases, operating systems, networks, and virtual machines.OpenVAS receives updates daily, which broadens the vulnerability detection coverage. It also helps in risk assessment and suggests countermeasures for the vulnerabilities detected.
W3AF is a free and open-source tool known as Web Application Attack and Framework. This tool is an open-source vulnerability scanning tool for web applications. It creates a framework which helps to secure the web application by finding and exploiting the vulnerabilities. This tool is known for user-friendliness. Along with vulnerability scanning options, W3AF has exploitation facilities used for penetration testing work as well.Moreover, W3AF covers a high-broaden collection of vulnerabilities. Domains that are attacked frequently, especially with newly identified vulnerabilities, can select this tool.
Acunetix is a paid web application security scanner (open-source version also available) with many functionalities provided. Around 6500 vulnerabilities scanning range is available with this tool. In addition to web applications, it can also find vulnerabilities in the network as well.Acunetix provides the ability to automate your scan. Suitable for large scale organizations as it can handle many devices. HSBC, NASA, USA Air force are few industrial giants who use Arachni for vulnerability tests.
GoLismero is a free and open-source tool used for vulnerability scanning. GoLismero focuses on finding vulnerabilities on web applications but also can scan for vulnerabilities in the network as well. GoLismero is a convenient tool that works with results provided by other vulnerability tools such as OpenVAS, then combines the results and provides feedback.GoLismero covers a wide range of vulnerabilities, including database and network vulnerabilities. Also, GoLismero facilitates countermeasures for vulnerabilities found.
Buyers tend to feel safer when making a transaction with your business, and you should find that this drives your revenue up. With the patent-pending scanning technology, SiteInspector, you will enjoy a new level of security.
As far as determining if it is "vulnerable", that may take some further investigation. Parameters like that aren't inherently vulnerable, but their existence in CTF problems often signals a SQL injection problem. To determine whether an actual issue exists, you can test it manually or use a tool like sqlmap, which will test all parameters and find vulnerable ones.

Nmap is a frequently used tool for folks in the sysadmin space as well as those pesky "hackers." It's great for testing network connectivity and server availability, but it can also help to identify vulnerable network daemons to both good and bad people. I'll show you how you can use it as a force for good and how others might use it as a force for evil.
I'll run some tests against a virtual machine I previously built. The how-to on setting up the testing machine is outside the scope of this article, but please do look up metasploitable in your preferred search engine if you want to test against a system with loads of known vulnerable daemons for learning and testing. Of course, don't expose such a system to any public network; it will likely be compromised in no time. But that's the point, right? To determine how to help defend against such attacks.
Wow, that's a lot of information. Fortunately, that is to be expected in this test environment. What's happening here is that Nmap is sending queries to the various ports and eliciting a response from the daemon on each port. The daemon's responses are compared to the nmap-services database (which is just a text file) to find matches.
Ok, that confirms it. The next question is, "Does this version of OpenSSH server have any known vulnerabilities?" You'll need to check for published vulnerability notifications. Head over to the NIST National Vulnerability Database to find out:
As an added bonus, vulners does a better job finding potential issues. The vulners script is more intelligent about matching the version number and found notices that include version ranges, including 4.7p1. A search in the NVD database turns up a note that only specifically mentions 4.7p1. That's a big plus.
Now that you know you can find vulnerable daemons based on the version number, is there a way to protect your systems? You could certainly configure firewall rules to help out, but maybe you can also fool Nmap.
If you suspect that malicious actors will scan your systems using the same tools that you do (And, they likely will), maybe you can use that to your advantage. Perhaps you can hide or alter the version number of applications such that these types of scans won't return useful results to the attacker. It's possible to do so in some cases. Some applications allow you to change the banner. Using vsftpd as an example, scan for FTP servers on metasploitable, and you'll find:

The Metasploitable virtual machine is an intentionally vulnerable version of Ubuntu Linux designed for testing security tools and demonstrating common vulnerabilities. Version 2 of this virtual machine is available for download and ships with even more vulnerabilities than the original image. This virtual machine is compatible with VMWare, VirtualBox, and other common virtualization platforms. By default, Metasploitable's network interfaces are bound to the NAT and Host-only network adapters, and the image should never be exposed to a hostile network. (Note: A video tutorial on installing Metasploitable 2 is available here.)
Metasploitable 2 has deliberately vulnerable web applications pre-installed. The web server starts automatically when Metasploitable 2 is booted. To access the web applications, open a web browser and enter the URL http:// where is the IP address of Metasploitable 2. One way to accomplish this is to install Metasploitable 2 as a guest operating system in Virtual Box and change the network interface settings from "NAT" to "Host Only". (Note: A video tutorial on installing Metasploitable 2 is available here.)
From the DVWA home page: "Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is damn vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, help web developers better understand the processes of securing web applications and aid teachers/students to teach/learn web application security in a class room environment.".
Additionally, an ill-advised PHP information disclosure page can be found at In this example, the URL would be The PHP info information disclosure vulnerability provides internal system information and service version information that can be used to look up vulnerabilities. For example, noting that the version of PHP disclosed in the screenshot is version 5.2.4, it may be possible that the system is vulnerable to CVE-2012-1823 and CVE-2012-2311 which affected PHP before 5.3.12 and 5.4.x before 5.4.2.
In order to resolve the complexity of matching the actually running applications to their source code, we focused on a tool scanning the compiled binary code directly. In order to filter out irrelevant results, we chose to scan for the feature which provides a robust way to write off a significant fraction of endpoints as non-vulnerable (types to which the endpoints bind the requests), and thus help teams focus on updating the parts of their software which may actually be vulnerable.
After conducting an internal research, we can confirm that the JFrog DevOps platform is not vulnerable to SpringShell (CVE-2022-22965) or the recent RCE vulnerability in Spring Cloud Function (CVE-2022-22963).
JFrog Artifactory and JFrog Xray can detect artifacts vulnerable to the SpringShell vulnerability, for any supported artifact type, and is augmented with detailed research data and mitigations. Read our remediation how-to blog post to learn how to best to use the JFrog Platform to find, fix, and fortify your software supply chain. 2ff7e9595c
