Advanced Web App Penetration Testing Services
Hey there! At Nextdoorsec, we provide top-notch web application testing service to ensure your website and/or custom-developed application is secure. Our skilled engineers conduct full, unauthenticated, and authenticated testing based on strict OWASP guidelines. We know how important it is to identify weak points across the entire web application to keep your applications and data safe. That’s why we hunt for OWASP Top 10 vulnerabilities, map and enumerate websites, test for injection attacks (SQL, JavaScript, LDAP, etc.), test for remote code execution, and even perform malicious file upload abuse testing, among other things.
You can rest easy knowing that all testing follows the OWASP v4 guidelines and checklist. Our team uses a variety of tools, such as Burp Suite Pro, Nessus Vulnerability Scanner, Nmap, Nikto, Dirbuster/Dirb/Dirsearch, sqlmap, BeEF, Metasploit, Qualys SSL Scanner, BuiltWith/whatweb, and manual review, to ensure a comprehensive assessment of your web application. So why wait? Let Nextdoorsec help you secure your web applications today!
Our Methodology
At Nextdoorsec, we follow industry-standard methodologies such as NIST SP 800-115 Technical Guide to Information Security Testing and Assessment and OWASP Testing Guide (v4) to provide offensive cybersecurity services to our clients. In addition to these, we also use customized testing frameworks to ensure that our testing covers all aspects of your IT infrastructure and helps you identify and remediate vulnerabilities before attackers can exploit them.
PLANNING
At Nextdoorsec, we start each project by gathering customer goals and obtaining rules of engagement. This ensures that we fully understand our client’s needs and requirements, allowing us to tailor our offensive cybersecurity services to best meet their needs.
DISCOVERY
We kick off our offensive cybersecurity services by performing a thorough scanning and enumeration process. This helps us identify any potential vulnerabilities, weak spots, and possible exploits that can compromise your organization’s security.
ATTACK
Nextdoorsec will exploit possible vulnerabilities to confirm them. This helps us assess each vulnerability’s effect on your IT infrastructure. Once successful access has been obtained, additional discovery will be conducted to explore the extent of the potential risks.
REPORTING
Nextdoorsec carefully documents all identified vulnerabilities, successful and unsuccessful exploitation attempts, and overall company strengths and weaknesses to provide comprehensive and actionable reports to our clients.
What vulnerabilities and tests does our External Penetration Test cover?
At Nextdoorsec, our External Penetration Tests comprehensively cover the most critical external network and software vulnerabilities recognized by the industry.
💣 Injection
At Nextdoorsec, we like to spice things up by exploiting injection flaws, such as SQL or OS command injection, by delivering hostile data to web apps. It’s like giving your website a spicy kick, but with the added benefit of identifying and fixing vulnerabilities before the bad guys can exploit them.
💣 Malicious file uploads and remote code execution
We also test for malicious file uploads and remote code execution in web applications. These vulnerabilities allow attackers to upload malicious files to your web app and execute arbitrary code on the server.
💣 Broken Authentication and Session Management
We go beyond identifying weak authentication and session management mechanisms in your web app. We exploit these vulnerabilities to potentially compromise passwords and session tokens or masquerade as other users.
💣 Insecure Direct Object References
We are skilled at exposing and manipulating direct object references in web applications. We exploit references to internal files or keys to gain unauthorized access to sensitive data. This common vulnerability can be easily overlooked, but our team is diligent in identifying and exploiting these weak points to ensure your web application is secure.
💣 Security Misconfiguration
We leave no stone unturned regarding web app security. In addition to the OWASP Top 10 vulnerabilities, we also focus on security misconfigurations at all tiers of a web app. These misconfigurations could include errors in the web server, front-end frameworks, or database, all of which can lead to the extraction of sensitive data.
💣 Cross-Site Scripting (XSS)
We perform thorough client-side testing to detect and exploit user authentication, session management, and access control vulnerabilities. This includes attempting to hijack user sessions through the execution of client-side scripts or redirecting users to controlled websites.
💣 Missing Function Level Access Control
We use various techniques to simulate real-world attacks on web applications. Our team specializes in forging hostile requests that manipulate web applications to gain unauthorized access to application functionality.
💣 Sensitive Data Exposure
We recognize the importance of safeguarding sensitive data stored in your web application’s database. Our team of experts conducts comprehensive tests to uncover any data stored improperly within the database. We pay special attention to sensitive information, such as credit card details and authentication credentials, which may be at risk of exposure.
💣 Cross-Site Request Forgery (CSRF)
We take a client-side approach to web application testing. We uncover flaws that attackers can exploit to force users into sending seemingly legitimate requests to vulnerable web applications. By doing so, we can identify potential vulnerabilities that could be used to gain unauthorized access to sensitive data or application functionality.
💣 Unvalidated Redirects and Forwards
We thoroughly assess web applications for unvalidated redirects, which attackers can exploit to redirect users to malicious websites or access unauthorized information and endpoints. Our team identifies entry points for unvalidated redirects and carefully uses them to demonstrate the potential impact of such vulnerabilities.
💣 Using Components with Known Vulnerabilities
We conduct Custom App Penetration tests to identify potential security weaknesses in all components of your web application. We thoroughly analyze libraries, frameworks, software modules, and other vulnerable components that attackers could exploit to compromise your web app.
