Karim Rahal, Detectify Crowdsource hacker, is a 17-year-old web-hacker who has been hacking for the greater part of his teenager years. At age 13, he started to responsibly disclose vulnerabilities—and he even blogged about one he found in Spotify! Karim still makes time for bug bounty programs, despite school. We asked Karim to tell us why Firefox is the best choice from a white hat hacker’s point-of-view.

Detectify Crowdsource hacker, Alyssa Herrera, is a full-time bug bounty hacker and web application security researcher who works to protect organizations.

The backend developer team at Detectify has been working with Go for some years now, and it’s the language chosen by us to power our microservices. We think Go is a fantastic language and it has proven to perform very well for our operations. It comes with a great tool-set, such as the tool we’ll touch on later on called pprof. However, even though Go performs very well, we noticed one of our microservices had a behavior very similar to that of a memory leak.

Pulse Secure and Fortinet have announced advisories detailing a critical vulnerability found that enables an unauthenticated user to conduct file disclosure in SSL VPN.

There are times where an attacker can hack a system and yet nothing is sent back, and this is classified as a blind vulnerability. This article will explain blind vulnerability detection and how Detectify’s scanner detects them: If we simplify web hacking, it usually means that an attacker is sending some data from their computer to a server, the server processes the data and then sends something back to the attacker.

We have written about Content Security Policy (CSP) on Detectify Labs before. But maybe you’re wondering why should you have it on your site to begin with? This article will explain why having one can prevent header exploits with attributes and common bypasses. CSP is a response header that instructs the web browser from what sources it is allowed to include and execute resources from.
