This is a short blog post on how you can get root access on a Android 12 emulated device with Google services, using a tool (script) called rootAVD by newbit1. I also share a few recommendations which are helpful during mobile analysis. Android Studio For mobile analysis I generally use my Google Pixel 3a device. However, sometimes I will try to avoid it if I can, especially when I’m only curious about an app’s network traffic or API endpoints....

In this post I will go into technical details on what attackers could do with the stolen encrypted vaults, specifically how they could use tools like Hashcat to crack vault passwords and get access to sensitive log-in credentials. To simulate the stolen data, I will use my test Lastpass account to extract an encrypted vault from the Chrome Browser extension on macOS. Following this, I will use a wordlist attack to bruteforce the vault which has a weak and guessiable password....

A short blog on how to bypass certificate pinning on the ProtonVPN macOS app using Proxyman and Frida. ProtonVPN is a VPN service operated by the Swiss company Proton AG. The service features a cilent application that users can install on various platforms, such as Android TV and Chromebook. I’ve personally had a proton email account for a quite a while now, but never really looked into the VPN service. I was mainly curious at how the macOS app communicates with the backend, and what API end-points it talks to....

In this post I will be comparing root detection features on 24 UK mobile banking apps using the latest version of Magisk (v24.3) on a Google Pixel 3a. You can head straight to the comparisons table if you want to see the results. Test Device The device used was a Google Pixel 3a running Android 10. It had been rooted using the latest version of Magisk which was v24.3 (at the time of writing)....

Back story As part of an out-of-country car repair, my partner’s dad suspected that his transmission had been switched out for a faulty one without his permission. He noticed that after a second trip to a different mechanic, the car was not performing as expected so he asked me to help find out when his part was changed. The vehicle was a Hyundai Santa Fe 2008 bought in Bulgaria. It had a VIN of KMHSH81WP8U272568, with a transmission number of U7LFP467454....

This post will describe how I discovered a security flaw in Pod Point’s mobile app API endpoints. It covers bypassing certificate pinning with Frida, and demonstrate how attackers can steal full names, addresses, charging history, and more by simply having a registered account that anyone can obtain. Pod Point Pod Point is a UK based company established in 2009 that provides electric vehicle charging equipment to both businesses and individuals. It also operates what’s called the “Pod Point Network” where customers can use charge points across the country with a mobile app....

I recently decided to improve my home network by purchasing a pfSense box. I wanted to ditch my ISP issued router, a Tilgin HG2381 router which works well for simple networks but fails to offer advanced configuration options, like support for wireguard VPN or VLANs. HyperOptic HyperOptic is a UK broadband provider which supports both IPv4 and IPv6 address assignment. For IPv4 addresses they use Carrier-grade NAT (CGN) which doesn’t allow exposing a service using port forwarding....

UPDATE (20-Mar-2022): MagiskHide has been dropped from Magisk 24.3. Checkout my blog post on comparing root detection for 24 banking apps where I also use Frida to spawn apps. For mobile app analysis, using a rooted device with Magisk and Frida has become my bread and butter. I’m aware that emulators exist (which I also use) but solutions, such as Android Studio or Genymotion fail to offer the same level of performance as a physical device....

Update (25/11/21) added a section on Page Rules. For markuta.com I now use Hugo with a theme called PaperMod. Github is still used storage on a private repository (Github pages doesn’t allow private repos for free accounts). And Cloudflare Pages is linked to Github to deploy the website. Requirements To get started you need the following: Hugo and Git software Github account (free) Cloudflare account (free) Domain name (not required but nice to have) Install Software You need to make sure Hugo and Git are installed....

In this blog post I’ll be covering how to install a self hosted Bitwarden server as a password management solution using Docker on a Raspberry Pi. We will get two containers running (Bitwarden server) and (Nginx reverse proxy). I’ll also go into hardening the Bitwarden configuration and applying 2FA for log-ins. What is Bitwarden? Bitwarden is an open-source password management solution. It supports almost all major systems. The version we’re going to be using is the unofficial one created by Daniel Garcia, Github page: https://github....
