@Rhynorater @therceman There is a case: JS in html attributes will interpret html encoding: onclick="console.log('hello'-alert()-'')"

@DOBBELAEREW @intidc I thought NDA's can't be enforced when reporting illegal activities. Consumer protection is a protected domain under whistleblower's law. You can only publish after reporting to internal & federal channels to no avail.

Vanaf vandaag laat de Belgische wet ethisch hacken zonder voorafgaande toestemming toe. Maar wat zijn de kleine lettertjes, en kan iedereen nu zomaar overal aan het hacken slaan? Een draadje 🧵👇

@nnwakelam Back in the day, you could pair that with the x-bufferbot header. That would cause the target to forward to prerender[.]io. Prerender would honor the x-forwarded-host and render the wrong site. That would get cached, and result in takeover of the target origin.

Followed @Agarri_FR 's Mastering Burp course last week, and it was awesome. Highly recommended if you want to bring your Burp skills to the next level.

@honoki I would use this! To quickly copy all UUIDs from a target for example. Way better than the 'strings project.burp | egrep' oneliner I'm using now.
