Free workshop: ph0wn Labs #3

Nicolas Rouvière, of Ph0wn and SHL, will show you how to use Qiling in practice, for dynamic binary emulation.

Don't miss it! This is on-site only, at SHL, on June 19 at 7pm.

Venue:
Sophia Hack Lab
2323 Chem. de Saint-Bernard
Space Antipolis Batiment 9
06220 Vallauris - Sophia Antipolis, France

In 2024, Nicolas used Qiling to solve the Ph0wn CTF teaser. See how here:

Бинарный формат вместо текста

Как быстро, без боли и страданий организовать хранение структурированных данных в бинарном формате. А затем и их передачу при необходимости. А потом, немного подумав, ещё их обнаружение в «замусоренном» потоке.

Alternatively, you can put #writefreely AND another webservice for your images behind #Ngnix. Lets say `wf.yourdomain` and `images.yourdomain`
