New writeup hope you like it ❤️ A simple idea.... furiouskernel.medium.com/account-takeov…
I earned $1000 for my submission on @Bugcrowd #ItTakesACrowd #bugbounty Tip: If a site generates a custom PDF using user input, test for HTML injection. If it works, try SSRF via an iframe to read metadata files: <iframe src="http://169.254.169.254/latest/meta-data/"></iframe>
Just got a bounty on @StandoffBB for a logic bug 🤩 One of the best platforms ever!
Happy to have contributed to secure @komoot The bug is now fixed by the security team 💪 >> Try to bypass 403 endpoints with URL encoding like: %2e → . %2f → / %5c → \ %20 → space %09 → horizontal tab %0a, %0d → line feed, carriage return thunderforest.com/about/security/
How do we turn bad SSRF (blind) into good SSRF (full response)? The @assetnote Security Research team at @SLCyberSec used a novel technique involving HTTP redirect loops and incremental status codes that leaked the full HTTP resp. It may work elsewhere! slcyber.io/assetnote-secu…
Think you've found an RCE? Use the `time` command with cURL and a `sleep 5` payload to see how long the server takes to respond. If it takes longer than 5 seconds then may have confirmed an RCE! 🚀
Real Human Hacker vs AI Agent Hacker
Hi, I need your help but couldnt contact you in message here. How can I contact you? I found this bug and the team sent me this... @coffinxp7
🧠 Session Fixation → Account Takeover 1️⃣ Attacker sets a known session ID (via link, cookie, etc.) 2️⃣ Victim logs in — app accepts attacker’s session ID 3️⃣ Session remains valid after login 4️⃣ Attacker uses same ID to hijack the account 🎯 Full session takeover #bugbounty
APPLE XSS Vulnerability 🔍 Stored XSS vulnerability discovered in an Apple web service — PoC, full breakdown, and disclosure process included. 📺 youtu.be/9fkEH78n2c4 #BugBounty #XSS #CyberSecurity #Apple
🧠 WAF Bypass via Path Normalization (LFI/RFI) 1️⃣ WAF blocks direct access to /etc/passwd 2️⃣ Attacker sends: /././etc/passwd, /..%2fetc/passwd, or /etc/./passwd 3️⃣ Server normalizes path before processing 4️⃣ WAF doesn’t decode → bypass! 🎯 Filters fooled, exploited #bugbounty
How did we (@AmirMSafari) earn $50k using the Punycode technique? I’ve published a detailed blog post about our recent talk, we included 3 attack scenarios, one of which poses a high risk of account takeover on any "Login with GitLab" implementation blog.voorivex.team/puny-code-0-cl…
