1/ New #MuddyWater 🇮🇷Infra detected; moves to #Metasploit and #HPAnywhere/#Teradici tool added?

@GroupIB_TI released a great report detailing MuddyWater’s use of SimpleHelp Remote Support Software. They tracked the #APT's infrastructure using Etags.

Let's take a look! 🧐 👇👇 Image
2/ First Etag(153): 🔟results.

First IP of interest: 👉164.132.237[.]67

If we now pivot on the SSH hash, we match on another IP:

👉3.6.222[.]144.

Looking at this IP, the SSL certificate presented mentions O=Teradici Corporation... Image
3/ Teradici (now HP Anywhere) allows for remote access to machines from any PCoIP client. 💻⬅️🌐⬅️💻

Indicating that MuddyWater may also be using HP’s Anywhere/Teradici as well as SimpleHelp?🧐 Image

If you utilise API hashing in your #malware or offensive security tooling. Try rotating your API hashes. This can have a significant impact on #detection rates and improve your chances of remaining undetected by AV/EDR. See below for an example with a Bind Shell vs #Virustotal.
Since API hashing can be confusing, most attackers won't rotate their hashes with each iteration of malware. Those same hashes can be a reliable detection mechanism if you can recognize them in code.
Luckily finding these hashes isn't too difficult, just look for random hex values prior to a "call rbp".
If you're unsure whether the value is an API hash, just google it and see if you get any hits. Most of the time, identification can be a simple google search away.

🚨 Cuidado con las descargas desde #Anonfiles (utilizado por muchos actores maliciosos), puede que en vez del archivo que querías, termines instalando, no solo 1, sino que 7 clases distintas de #Malware 👀

Revisemos por ejemplo: /anonfiles.com/7c62z4s9ob/Youtube_Viewer_rar

Al hacer click en "download" se descarga automaticamente un archivo que tiene de nombre "YouTube+Viewer.rar[.]zip" pero la descarga se realiza desde /yfilesstorage.com/Youtube+Viewer.rar.zip?c=AISJk2FCGQUA4ksCAENMFwAMAMyKTf0A (.ZIP protegido con contraseña) 🤔

Lamentablemente esto pasa desapercibido para usuarios menos prudentes.

Sin embargo, gracias a @hatching_io, podemos averiguar que lo que instalan realmente es #Arkei, #Metasploit, #Racoon, #Redline, #Smokeloader, #Socelars y #Vidar 😵
