Foundational Static Analysis: Analyzing Structures
The question is asking me "In the disassembly at address 00401567, what is the structure EDX is pointing to? Look at Microsoft Docs for help!" At the very end of the briefing they go over the explanation of how to identify which offset is determining which call. I am 90% positive that the offset we are supposed to be identifying in this case is 0x17c. However within this SAME blurb while they are explaining the way the stack line up they simply identify which API the offset in their example is pointing to. THEY NEVER MENTION HOW THEY GOT THERE! I am sure that it requires some research an I have been trying to identify anything within MSDN database but I can't find a single clue how identify what API 0x17c is pointing to. I have even tried looking up references for the offset they had 0x138 which they identified as STARTUPINFO. (I googled both terms together.) Now I am most definitely missing something here. I step within the assembly analysis mayb ebut I am at a loss. If anyone could help me out I would appreciate it.FIN7 Threat Hunting with Splunk: Ep.3 – Execution Logs
For this lab I need to rebuild the PowerShell script using the three parts found in the PowerShell operational logs. Which I am able to do fairly easily but when I am required to obtain the MD5 hash of the file I am not getting the correct hash. I've removed any trailing white spaces and return characters. Not matter the setup, I just can't seem to find the special sauce on this one. I've tried numerous approaches and still get a no go. Any tips?Help needed for Threat Hunting: Mining Behaviour
Hey everyone! I need some help with this last question of a lab. I already identified the JSON authentication token and the packet that holds it. But within that packet, I just can't find the authentication key that identifies the miner. Anyone was able to solve and help? Thanks!Cybersecurity and philosophy
Fellow members of the Cyber family: I think the ancient philosophers, those who recognized their own ignorance, were motive: their curiosity to learn, to question, to go a step further, to not settle ... I would like to think that these qualities defined great thinkers. And may we never lose the ability to recognize and be surprised, in the face of threats; studying them, always. I have always believed that a “let's talk” can be more enriching than a “I denounce you”: learning, if possible, from the adversary and his geniuses. And, of course, let's keep learning: every day: tactics, techniques, procedure and vectors. Nobody said this was going to be easy, did they? :). Good luck!.
