Thought I would start a topic with a list of places to find malware samples. Feel free to post other sources if you have any... and remember live samples will be harmful to your computer so if you don't know what your doing and/or how to work with malware don't read any further for the sake of your own sanity...

Antivirus vs malwares difference???
by CodeExplorer- 1 follower

What is the difference between malwares and antivirus? I mean Antivirus slow down PC and erase legit files which are flagged as suspicious; not talking about the strange fact that protected/packed files are flagged as malicious. Anyway anti-viruses are still necessary or being careful on what you download from internet. And also I found hard to trust a single antivirus program. What antivirus you are using?

Someone on telegram intrigued me by telling me about software to read credit card chips, so here are some files that I got from the net. The first software in question, on which I came across: "EMVStudio" belonging to emvstudio.com If I look for the files on VT, it communicates with auth.emvstudio.com, I come across these 3 archives: EMVStudio.rar - 1ba1fac55003d2c966f0071b2c126169254b35a38b4e2b913557c4fb0faadfdb Contains 8d6dacff8a098b8d02202e8c6a4a65bbe20b332ba58d6165cca6f958187864c4 also a file named 'gp' who seem a config file. emvstudio_v1.1.1.rar - 0bd11f024845c07e0df8fe2f080f4925dc44a289e4e59b079be0a68ed2fc42a6 Contains emvstudio_v1.1.2.exe - ce9187aa…

I got hit by the Locky ransomware

A couple of days ago I was backing up some company server data, among which were some email inboxes. After downloading the archives I opened one of the emails to make sure the backup was successful. Apparently, that was a spam email with an infected attachment, so I lost all my data. All my files are encrypted with the .thor extensions, and I have a ransome note saying to visit jhomitevd2abj3fk.onion. From what I found online, this is an old ransomware (from around 2016), and there isn't a known way to decrypt the files. I've lost some stuff with quite a lot of sentimental value, and I don't really know how to proceed forward. I've been through a panic attack these d…

Hello everyone ! Having been in infosec for a few years now, particularly on the Red Team side, I'm keen to discover new things. I have some basic knowledge of reverse engineering, but nothing too crazy. As I'm about to start a new contract on the Blue Team side, I'd like to practice a bit before starting. So I'd like to know your opinion on an easy malware family to reverse for a beginner. Thank you.

Recently I caught some malware on my PC... I got rid of it and cleaned all places I could find in the system (Task Scheduler, autoruns, hosts, new user, remote manipulator software, WinDefender exceptions, AppLocker policy). I found the install script of that shit. Now I wonder what is inside all those malware binaries. So far I know they (or at least some of them) are compiled AutoIt scripts protected with Themida. I was Googling about that. That's how I came here. @koolk @root it looks like you are Jedi Masters here. Could you help me to take a look inside those exe's if I send you them?

Hi all, this is my analysis of Disk Knight, an old usb-spread worm (written in VB6) from 2007 that I first encountered at my school PC Lab around that time. ENGLiSH VERSiON: https://lucadamico.dev/papers/malware_analysis/DiskKnight.pdf iTALiAN VERSiON: https://lucadamico.dev/papers/malware_analysis/DiskKnight_ITA.pdf I'm also attaching both PDF files here, just in case. I'm more interest in old-school malware that have an interesting background history behind them (for example, Disk Knight became a worm due to some programming errors), have nice/funny (or scarry) payloads or are motivated by some weird physicological reasons: in other wor…

Hi, I'm studying Penetration Testing and part of the training obviously focuses on solving CTF challenges. You must be asking yourself how the name of the title is related to PT? Well, it's probably not that related, but there is a challenge that really caught my attention and I've been trying to solve it for a long time without success. The challenge contains a malicious file and the task is to investigate the file and find the FLAG hidden inside the file. So I will detail a bit about the malware and what I was able to understand from the code: Code details: Assembly - https://pastebin.com/asWi6a2M (IDA PRO) Decompiler - https://pastebin.com/4XmaQ…

Hi. In order to advance myself in malware analysis I solve tasks from widely known malware-traffic-analysis.net. But I'm also trying to dig deeper and fully analyze malware samples found in pcaps. The one that puzzles me a lot is from 2019-06-22 task. Particularly the file 2019-06-22-malware-retrieved-from-the-infected-Windows-host.exe.zip (md5: 90c90e8d3fa5ca583e966d2a34565899). https://www.malware-traffic-analysis.net/2019/06/22/index.html What exactly, is that it basically doesn't show any red flags during basic static analysis. # Its import table is pretty "herbivore". # Strings don't show any obvious indicators. # The only thing that looks strang…
