Cuckoo Sandbox VS HxD

You can detonate it into a VM running an instance of Cuckoo Sandbox. If you want to go the extra mile, you can dump the memory of said VM and analyse it with Volatility Framework. Also, if you want to quickly identify behavioural patterns in executable code, you can use Mandiant's CAPA tool (though idk if it works on .pdfs). Source: about 1 year ago

You should save a copy of the .exe, copy it into a VM running Cuckoo and get a report on exactly what the .exe does. Without this automated dissection, people are making educated guesses. They're probably right, but why not be certain? There is an online version too - https://cuckoosandbox.org. Source: about 1 year ago

You could use a service like cuckoo to check links/files. Source: over 1 year ago

I made my own lab in college using a series of VM's, A windows 10 machine that was packed with analysis tools, a kali listening machine (running inetsim or fakenet, I can't remember.) and I had remnux on another machine (which I ended up not really making use of, but it was there.) I used virtualbox and ran these VM's in an internal network, no internet access. Disabled all clipboard and file sharing after... Source: over 1 year ago

Another option if you want to self-host is https://cuckoosandbox.org/ . Of note, it's currently an unmaintained project so issues may not receive support, but it is free. Source: over 1 year ago

How does it compare to HxD? https://mh-nexus.de/en/hxd/. - Source: Hacker News / 3 months ago

By the sound of what happened it's possible that all files residing in the last 1TB got TRIMMed (https://www.300dollardatarecovery.com/trim/) by first aid. Can you check the corrupted videos with a hex editor (for example https://mh-nexus.de/en/hxd/) to see if they contain any information at all? If they got trimmed there will be large swathes of either 0xff or 0x00. Source: 6 months ago

You don't need to know anything about Hex-Editing to use this. You are only required to know how to copy-paste. That being said, you will need a Hex-Editor program and to know your save-file's location. I personally use HxD: https://mh-nexus.de/en/hxd/. Source: 11 months ago

Also, notepad is only good for editing text, not binary files. You should use a hex editor. I personally use HxD. I also found this online hex editor called HexEd.it. Source: 11 months ago

Anyway, due to the sheer size of the saves, I'd recommend using a hex editor like HxD rather than a text editor. Hex editors typically operate on just a small buffer at any given time, so opening and paging through the file is very fast. In theory, this might slow down full-file operations like a full text search, but in practice it doesn't seem to matter in this case. I opened a 100MB save that hasn't been... Source: 12 months ago
