30 distinct techniques documented for this family, organized by ATT&CK tactic.
EncroChat’s update server, at the web address “update.encrochat.ch”, was under French jurisdiction. EncroChat phones were set up to check for updates every time they were used... They would build an exact replica of EncroChat’s update server... Then they would send in Bad Binder.
We can use any non-Play Store Android device... We need Frida... Hooking the SDES::create function... We leverage Frida’s ability to define and call arbitrary functions to mimic program flow for creating and modifying the buffer in the process’s memory.
L’unité gouvernementale française STNCJ ... a exploité : La vulnérabilité CVE-2019-2215 dite « Bad Binder » ... Le 1er avril 2020, l’implant a été injecté via un faux serveur de mise à jour.
Frida was the heart of the French implant... It monitors instructions and will “hook” any process inside the processor by attaching from an “interceptor”. The hook triggers a “trampoline”, bouncing out of the intended program into exploit code written by the hacker.
Change class challenge_01’s variable ‘chall01’ to 1 ... challenge_01.chall01.value = 1;
Frida utilisé pour « hooker » l’application de chat com.esocrypt.chat.app.im via des « trampolines »
По MITRE ATT&CK jailbreak bypass - аналог Virtualization/Sandbox Evasion (T1497): приложение пытается определить модификацию среды выполнения, а атакующий маскирует этот факт.

In a lab setting, we set up a machine to view our own http(s) traffic using mitmproxy from our test device... We’ve included flows files in this post, which can be opened in mitmproxy to show the requests we’ve observed with location coordinates.
Each time a user opened their phone, Frida hooked the unlock password and sent it back.
...перехват методов через Credential API Hooking (T1056.004, Collection / Credential Access) в runtime.
Bruteforce check07Pin() then confirm with chall07() ... we can cycle through all the possible values from 9999 to 0000.
Основное применение в мобильном пентесте: ... извлечение ключей и токенов из памяти.

Following this same idea over and over for each type of packets, we can slowly learn what packets look like for each gamestate update... I was able to make a partial table of command bytes by reading the 11th byte of any command.
We need to get a running instance ... The following code will do it through the Java.choose Frida API.
On starting, every implant copied out the phone’s security keys, stored images and a full Realm message database.
Each time a user opened their phone, Frida hooked the unlock password and sent it back.
...перехват методов через Credential API Hooking (T1056.004, Collection / Credential Access) в runtime.
The data flowing into this address every hour now included up to tens of millions of data “objects” called JSONs... each reporting a single event on an infected phone, as it happened – every password entered, every image made or received, every message, every note made into or deleted from an encrypted EncroNotes container.
Through this link, the police server maintained communications with and could command every infected phone... The police malware server was also the exfiltration endpoint. From 2 April 2020 on... a torrent of, eventually, billions of data objects (JSONs) was sent to the police infrastructure.
After infection, as soon as a user booted their phone, the implant started running. It blocked the phone from sleeping, turned off logging, switched off the vital SELinux firewall, and opened up all phone processes for any purposes. It interrupted Marvin, a bespoke EncroChat logging system, to stop operators seeing it.
