Scenario During front-end development, we sometimes have to deal with code which cannot be imported easily into your ReactJS app. This situation arises frequently when dealing with a legacy codebase, or when you have a large, heterogeneous codebase with different teams taking care of different "sections" of the front-end. This article explores one method that … Continue reading RxJS: The bridge between plain JS and ReactJS
gRPC-Web has reached General Availability! The official blog announcement can be found here: https://grpc.io/blog/grpc-web-ga gRPC makes leveraging Protocol Buffers extremely easy, and ProtoBufs in and off itself has some very good advantages over REST when it comes to performance and contract-based development. However so far ProtoBufs are used typically in the backend to facilitate inter-microservice … Continue reading Pentesting gRPC-Web : Recon and reverse-engineering
Protocol Buffers (a.k.a ProtoBuf) and other binary serialization representations are gaining popularity, especially in inter-microservice communication. Unlike JSON or HTTP, ProtoBufs are not human readable (hence the "binary" part of binary serialization) , but that translates into an advantage of less overhead, leading to performance gains, and the ability to code against a fixed schema … Continue reading Pentesting gRPC / Protobuf : Decoding First steps
This article outlines a few "lessons learned" during an Android pen-test, specifically on which parts of my toolset I needed to update to accommodate newer android versions (Android v7+) MultiDex support One of the standard pen-test techniques is to decompile the App's source code. Typically this is done by converting the APK DEX code to … Continue reading Android hacking tools update for Sept 2018
OWASP ZAP is a very popular attack proxy typically used in Web Application penetration tests. Think "Open Source BurpSuite", and that's ZAP in a nutshell. It has become my go-to tool for penetration tests, and it definitely is a fantastic piece of software that ticks all my boxes - except one. The problem : Note taking … Continue reading First steps in writing a custom OWASP ZAP extension
In this article we explore how to build a custom Apache Nifi processor. Our objective is to build a custom NiFi processor, written in Java, that uses Selenium to scrape an arbitrary piece of information off a web-page. The end result will look like this: https://www.youtube.com/watch?v=alRC8owgjl4&feature=youtu.be This highlights the flexibility of Apache NiFi, showing off … Continue reading Apache NiFi: Custom Web Scraper Processor – Powered by Selenium
Apache Nifi is the result of an project open-sourced by the NSA. It's described as a "data traffic program"... For users familiar with the Elastic ecosystem, think of it as a GUI-enabled mashup of Filebeat, Winlogbeat and Logstash. In essence Nifi allows you to build data processing pipelines of arbitrary complexity and enrich the data or … Continue reading Apache NiFi: From Syslog to Elasticsearch
