In addition to this, since crypters are relatively smaller than RATs, modifying the code to defeat SBD is also much, much more convenient. HowToHack subscribe unsubscribereaders users here now Welcome! How do I make my rat exe FUD? We teach you how to do it, use it at your own risk. First of all, it doesn’t seem to me like you have a very good programming knowledge, otherwise you wouldn’t be asking this question.

Although creating your own allows you to easily destroy signatures simply by changing the code, it still requires quite a bit of effort and time to initially program one with full functionality. Encryption is a big part crypted crypters, hence the name.

The whole point of a custom crypter is that it’s custom, so there’s no unpacker for it. Also, remember how Anti Virus programs detect your virus in the first place, signatures, so don’t use common code, be creative, and go as dynamic as possible.

I could throw cry;ter you the simplest piece of malware in the world without any AV being able to detect it. NET crypters can do both of these methods easily, in fact, the reflective-assembly-loading code is just one line of code: Hope this helped you in some way.

Once you have the crypter, it’s very simple to just package your malware and deploy it. Intended for personal, non malicious and educational use.

Welcome to Reddit, the front page of the internet. I use xrypter software to produce the rat lol, I have good knowledge over networking but limited in software code.

Try to not trigger behavioural shields by not doing something incredibly suspicious. I understand this comment might not seem very useful but if you follow my advice it will be the most useful comment you’ll get for this post. HowToHack submitted 11 months ago by [deleted]. NET binary because they require dependencies to run which are not shared with native executables however, the RunPE method is still relatively simple.

This is what makes crypters or packers so popular. This depends on how the RAT was developed. If your stub is detected, just change your stub code around until it’s no longer detected. Oh yeah, make sure to use a robust crypto algorithm!

So to solve your problem, using an existing RAT or not needing to constantly change the code is a much more favourable option because it increases your efficiency to infect more users. I would go with that first. It isn’t difficult to bypass heuristic analysis, as long as you understand how it works.


To code a native crypter with these two options is not quite trivial with respect to executing a. Use of this site constitutes acceptance of our User Agreement and Privacy Policy.

The basics of reverse connections are done usually using assembly, however, which is why I recommend learning it in detail as well. It is true that it makes our job a lot more difficult, if you have something like Symantec Endpoint Security, but something well done, usually with reflective dll injection to bypass application-based limitation simple exe injection would also work works like a charm, provided you can obfuscate it well enough to bypass heuristics.

And, of course, make it so that the malware does NOT run under sandboxes and VMs, or anything of the sort. Invoke null, null ; while the RunPE method’s complexity stays the same as native crypters. Exploitation – it-sec-catalog – References to vulnerability exploitation stuff. It’s not like you’re going to distribute the key with the binary!
