A quick demo of how to identify "real" exported functions from a #obfuscated #IcedID dll file.

I'll also briefly touch on some #Ghidra tips, and how to extract #shellcode using a debugger.

A moderate sized thread😃
[2/13] You can find the relevant files here. Special thanks to @malware_traffic.

First, download the .zip in the screenshot.👇

Then unzip and locate the "rarest.db" file in the "scabs" folder.

(Make sure to do this inside an isolated Virtual Machine)…
[3/14] Drag the "rarest.db" file into Pe-Studio and navigate to the exports tab.

There are 11 exported functions here. 🧐

Most of them have junk names to throw off analysis.

One of them is "real", the rest are "decoys" which don't do anything if executed.

Hello @Uber! We know breaches suck. Wanted to reach out and support with some interesting information on the #uberhack. If you need any more details, feel free to contact us.

On September 16, vx-underground posted screenshots with evidence of access to #Uber internal systems, including #SentinelOne, #Slack and #AWS. The screenshots have been attributed to the threat actor teapots2022. Image
During Group-IB’s analysis of the screenshots, interesting artifacts have been found in the recently downloaded files tray. First 2 files are zip archives and have the same format: "LOGID-\d{7} with names LOGID-4952307" and "LOGID-4953756". Image

El correo sigue siendo una de las vías principales de transmisión en infección del #malware porque aquí, aparte de la solución de seguridad que adopte la empresa, existe otro elemento: El usuario.
(hilo) 🧵
Y este usuario llevará a cabo, de bien seguro, todas las acciones que no te esperabas. Para empezar, clicar en enlace que claramente son sospechoso. Pero el orden de las cosas será:
1) Clicar
2) Ver que salen cosas raras
3) Avisar al departamento IT

El correo anterior lo he recibido en una de mis cuentas empresariales. En el asunto, aparece el nombre de un antiguo cliente mío. En la lista de destinatarios está mi correo y el de otras personas que están en la agenda de correo de ese cliente y a las cuales no conozco.

Reverse Engineering a #CobaltStrike #malware sample and extracting C2's using three different methods.

We'll touch on #cyberchef, #x64dbg and Speakeasy from fireeye to perform manual analysis and emulation of #shellcode.

A (big) thread ⬇️⬇️
To follow along, download the sample from the link below. Then transfer the .zip into a safe VM environment.

My VM is a mostly default Flare VM with SpeakEasy installed on top.…
[3/23] Once unzipped (pw:infected), load the file into pe-studio for quick analysis. There isn't a lot interesting here, but take note that the file a 64-bit .dll with 4 exported functions.

Raspberry Robin is a malware that has been around for some time now and spreads via infected USB drives.
Here is what we have seen over the last 10 months. 🧵 1/12 #RaspberryRobin #malware

via @lazy_daemon
@sekoia_io and @redcanary have already published excellent technical analyses of this malware, so we won't go into more detail about it.……

🧵 2/12
Since December, 2021, we've seen several cases mostly in Hungary🇭🇺 and Germany🇩🇪 but also a few in Russia🇷🇺 and India🇮🇳.
The user always clicked the malicious link, so no automatic infection when the USB drive was plugged in. 🧵 3/12

A lot of talk about threat modeling lately. Let me give you some idea of why I hate it and think threat modeling is bullshit. I'll also tell you what I think is better. I'm going to use $BIGCO as my example. Here's a long thread.
#infosec #blueteam #malware #skincare
First, you constantly hear the snarky refrain "my threat model is not your threat model" from people trying to sound important. They don't have a "threat model". They have a superiority complex in their head about potential "threats" 🙄 It's silly. Show me your threat model. 🔜🧵
Oh, you don't actually have it written down and it's not based on data, but based on just general things you're worried about? All in your head? 🆗🆒 Sounds like your idea of a "threat model" and mine really are pretty different.

NEW: Multiple attackers increase pressure on victims, complicate incident response

Sophos’ latest Active Adversary report explores the issue of organizations being hit multiple times by attackers...

There’s a well-worn industry phrase about the probability of a cyberattack: “It’s not a matter of if, but when.”

Some of the incidents @Sophos recently investigated may force the industry to consider changing this: The question is not if, or when – but how many times? 2/17
In an issue we highlighted in our Active Adversary Playbook 2022, we’re seeing organizations being hit by multiple attackers. 3/17

What is a Malware?
Intrusive software known as malware is created specifically to harm and incapacitate computers and computer systems. The term "malicious software" is often shortened to "malware."
Malware typically aims to accomplish one of the following:

Give an attacker remote access to a compromised machine.
From the compromised device, you can send spam to unknowing recipients.
Investigate the local network of the affected user.
Steal sensitive information.

#Russia #cyber as part of war in #Ukraine - "We learned a lot" Deputy National Security Advisor of Cyber & Emerging Technology, Anne Neuberger tells #AspenSecurity

"At 1st we've seen several different variants of destructive #malware used...closely aligned w/its invasion"
#Ukraine - "They expected the incidents & worked closely to prepare for it," per Deputy NSA Neuberger

"We had teams on the ground from various agencies, virtually, & on the ground as well helping out"
#Russia's use of #cyber - "There are any number of theories for what we saw & for what we didn't see" per Deputy NSA Neuberger

#ChromeLoader #malware persists via obfuscated content stored in the registry. Here's how to decode it using #Cyberchef.
1/ ImageImageImage
2/ First, locate a scheduled task containing content that you suspect to be chromeloader malware. Decode the first stage using "From Base64" and "Remove Null Bytes". This will give you the first stage loader in its #decoded form. Image
3/ Next, check the location of the next stage in the registry. This should be near the beginning of the code. 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.

With #P2E's popularity, threat actors are leveraging on the fact that excited players are ready to jump on board to test the new game (and earn at the same time).

Here's a 🧵about a #Redline stealer #malware from a "project" that recently launched a "beta test" Image

I came across @DheerajShah_'s thread about how he was almost hacked, and one of the commenters caught my eye.

@_Starkcrypto shared that he was compromised by a project claiming to be a "p2e beta testing"

That project is @rworldp2e (now @R_WorldP2E). As they were called out by Stark, the account changed the username lol. Here's the ID though: 1467094027480625155

It is an impersonation of the original project called @ReptileChronic @R_chronicls
