A project dedicated to provide DDoS protection with proof-of-work PoW Shield provides DDoS protection on the OSI application layer by acting as a proxy that utilizes proof of work between the backend service and the end-user. This project aims to provide an alternative to general captcha methods such as Google’s ReCaptcha that has always been a pain to solve. Accessing a web service protected by PoW Shield has never been easier, simply go to the url, and your browser will do the rest of the verification automatically for you. PoW Shield aims to provide the following services bundled in a single webapp / docker image: proof of work authentication ratelimiting and ip blacklisting web application firewall Features Web Service Structure Proxy Functionality PoW Implementation Dockerization IP Blacklisting Ratelimiting Unit Testing WAF Implementation Multi-Instance Syncing (Redis) Changelog v2.1.2 Changes: Update dependencies [hide][Hidden Content]]

A project dedicated to provide DDoS protection with proof-of-work PoW Shield provides DDoS protection on the OSI application layer by acting as a proxy that utilizes proof of work between the backend service and the end-user. This project aims to provide an alternative to general captcha methods such as Google’s ReCaptcha that has always been a pain to solve.

PoW Shield aims to provide the following services bundled in a single webapp / docker image: proof of work authentication ratelimiting and ip blacklisting web application firewall How it Works So basically, PoW Shield works as a proxy in front of the actual web app/service. It conducts verification via proof-of-work and only proxies authorized traffic through to the actual server. The proxy is easily installable and is capable of protecting low-security applications with a WAF. Here’s what happens behind the scenes when a user browses a PoW Shield-protected webservice: The server generates a random hex-encoded “prefix” and sends it along with the PoW Shield page to the client. Browser JavaScript on the client-side then attempts to brute-force a “nonce” that when appended with the prefix, can produce a SHA256 hash with the number of leading zero-bits more than the “difficulty” D specified by the server. i.e. SHA256(prefix + nonce)=0…0xxxx (binary, with more than D leading 0s) Client-side JavaScript then sends the calculated nonce to the server for verification, if verification passes, the server generates a cookie for the client to pass authentication. The server starts proxying the now authenticated client traffic to the server with WAF filtering enabled.

PwnFox PwnFox is a Firefox/Burp extension that provides usefull tools for your security audit. If you are a chrome user you can check [Hidden Content]. Single click BurpProxy Connect to Burp with a simple click, this will probably remove the need for other add-ons like foxyProxy. However, if you need the extra features provided by foxyProxy you can leave this unchecked. Containers Profiles PwnFox gives you fast access to Firefox containers. This allows you to have multiple identities in the same browser. When PwnFox and the Add container header option are enabled, PwnFox will automatically add an X-PwnFox-Color header to highlight the query in Burp. PwnFoxBurp will automatically highlight and strip the header, but you can also specify your own behavior with addons like logger++. Security header remover Sometimes it’s easier to work with the security header disabled. You can now do it with a single button press. Don’t forget to reenable them before testing your final payload.
