Surprising Differences Between TLS and SSL Protocol TLS is simply a successor of SSL 3.0, TLS is a protocol which provides Data encryption and Integrity between communication channels. SSL 3.0 is served as a base for TLS 1.0. SSL OR TLS Which is good? We use to believe that TLS 1.0 is a Successor of SSL 3.0. As we know SSL3.0 are very old and recent attacks like POODLE, BEAST and other attack vectors made SSL3.0 lifeless as a security protocol. Due to POODLE attack, SSL v3 is being completely disabled on web sites around the world. Then the BEAST attack which completely break web sites running on older SSL v3.0 and TLS v1.0 protocols. Sadly still some of the websites does not use TLS, you can check your website configuration using Comodo SSL analyser. TLS Handshake Protocol When a TLS  and server first start communicating, they agree on a protocol version, select cryptographic algorithms, optionally authenticate each other, and use public-key encryption techniques to generate share...

 The OWASP Top 10 security risks point out the common vulnerabilities seen in web applications. But it does not list the set of attack vectors that WAFs (Web Application Firewalls) can simply block. This is but a myth often propagated by many a security vendor. OWASP Top 10 protection is the joint responsibility of the security vendor and the application developers. There is a lot that an effective security solution and WAF can do to secure OWASP vulnerabilities. But in some cases, the security solution may not be able to give complete coverage against it and requires the developers/ organizations to take preventive action. In this article, we help you understand how a comprehensive, intelligent, and fully managed WAF can augment OWASP Top 10 protection. A Quick Introduction to WAF WAF is the first line of defense between the web application and the web traffic, filtering out malicious requests and bad traffic at the network edge. The best WAFs are part of larger security solutions...

  A Dictionary attack is one of the ways through which the attackers try to gain access to the keys of the reign. Bad actors take advantage of people using common dictionary words as their passwords. A study has proved how the majority of people like to reuse their passwords or use common phrases that are relatively easy to remember.  Databases used in dictionary attack does not only include the common dictionary words, but also the passwords leaked in previous attacks. Dictionary Attack Using Burp Suite Tool: BurpSuite is indeed a great tool for testing vulnerability in web applications. We are here using its free-version which has limited capabilities but works well for learning! Lets began the process to brute force/dictionary attack.  So, we’ll be using VM setup, with Kali and Bee-Box as a Web Server which is the victim. The process for setting up the Burp Suite and proxy in the browser is explained here. Make sure you have set up your proxy to your localhost. STEP1:...

 Hi everyone and welcome back on this new write-up. Today, I would like to talk about a vulnerability I found on some programs that allowed me to bypass their 2FA protections. On a side note, due to the fact that the programs are private, all the informations about the websites will be redacted. That’s said, let’s start ! Introduction : As many hunters, when I start my research on a new bug bounty program, I use the application as a lambda user. This allow me to understand how the applications work and notice which features can be interesting to test. I noticed that the applications had a 2FA feature, I enabled it and I started to play with it. For those who are not familiar with the concept of 2FA (Two-factor authentication), this can be defined by: Two-factor authentication (2FA) is a way to add additional security to your account. The first “factor” is your usual password that is standard for any account. The second “factor” is a verification code retrieved from an app on a mobi...
