I love the journey John goes on in these videos. From "HOW DO THEY KNOW IT'S NETWIRE??" to "Oh here's a super unique obfuscation key that's an obvious IOC and they literally create directories named 'Netwire'"

Last week I dig into a .Net Assembly with some base64 encoded string in it. And thanks to the Videos of John I recognize the string and I know what to do with it.

To be honest, I'm surprised that you haven't tried using Windows Terminal + SSH to connect to your remnux box for these deobfuscation videos... That'd be pretty slick.

Very nice video! One question. I am sharing data from REMnux to FLARE VM, but when I look at the paths, they are interacting like local data. How do you build such a lab environment? I am interested because I always use KVM to share files over a virtual network.

Blindly search-replacing variable names is a VERY breakable thing. Imagine someone deliberately starting with a "Set aaabbbccc = myObject" , and using "aaabbbcccqqq" and "CustomObjectqqq" further down. You are going to mess up when someone starts doing that.

You can use exact match which negates your point.

@blinking_dodo 2 жыл бұрын

@@boomson3082 exact match doesn't care about what is directly after your search. replacing "ab" with "x" in "abc" will still result in "xc".

@boomson3082 2 жыл бұрын

@@blinking_dodo it does though, I just tested in on my machine. Would you like a video? Go test it yourself. You can have it set to find 'ab' and it will find all or you can have exact match where it does care about only ab and not abc. But either way, even if he didnt use exact search the code would obviously stick out after the replaced text unless it was the exact amount of characters.

@doyoufeel...thatyoulackcri6760 2 жыл бұрын

can't you just regex replace? I am no regex expert but something like w/word shouldn't that find the exact word and not if it is part of a word? you can do that in sublime, no?

It makes since why it works fine in firefox but not with curl because according to cloudflare, error code 1010 means that the owner of the website has banned your access based on your browser's signature

Why would something not respond to curl but to a browser ? 10:25 , didn't know that can happen.

@casper64 2 жыл бұрын

The context of a request with curl is different, for example the user agent is different so the server would know the request didn’t came from a browser.

Hey John Hammond, Can you please make a video on Configuring Ubuntu as a Lab? I was trying to setup Ubuntu-latest LTS version, but somehow when I install some git-software(specifically: portkali), the whole GUI crashes and boots only on Terminal. i tried different article to install GUI or boot into it, but no outcome. I maybe tried 4times for 3 days, but it didn't worked. Also, my Ubuntu navigation wasn't great, don't know, is it that I am not used to Ubuntu or just it's like that. But, yeah, hopefully you can help.
