Bugcrowd has released its second round of updates to Bugcrowd University (BCU), a free and ungated library of educational hacking tutorials. The new collection includes five modules that cover high-impact bug types rated as P1-P3 on the Vulnerability Rating Taxonomy, such as Server Side Request Forgery, XML External Entity Injection, GitHub Recon and Sensitive Data Exposure, and Recon and Discovery. These modules are designed to help hackers hone their skills in techniques that can result in large bounty payouts. The modules are led by security experts and community members, including Jasmin Landry, Jay Turla, Alyssa Herrera, Aditya Gujar, Majd Aldeen Atiyat, Sajeeb Lohani, and Vortex, who share their knowledge on advanced tools like Burp Suite, SSRF bugs, XML External Entity Injection vulnerabilities, GitHub Recon, and Recon and Discovery. The modules are available for researchers to learn more about these techniques and improve their bug hunting skills.
