Fud crypter

This is what makes crypters or packers so popular. Hope this helped you in some way. NET crypters can do both of these methods easily, in fact, the reflective-assembly-loading code is just one line of code: And, of course, make it so that the malware does NOT run under sandboxes and VMs, or anything of the sort. Become a Redditor and subscribe to one of thousands of communities. We teach you how to do it, use it at your own risk.

To code a native crypter with these two options is not quite trivial with respect to executing a.

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. HowToHack submitted 11 months ago by [deleted]. Oh yeah, make sure to use a robust crypto algorithm! The whole point of a custom crypter is that it’s custom, so there’s no unpacker for it. The basics of reverse connections are done usually using assembly, however, which is why I recommend learning it in detail as well.


If your stub is detected, just change your stub code around until it’s no longer detected.

Log in or sign up in seconds. 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. I could throw at you the simplest piece of malware in the world without any AV being able to detect it. In addition to this, since crypters are relatively smaller than RATs, modifying the code to defeat SBD is also much, much more convenient.

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.

Also, remember how Anti Virus programs detect your virus in the first place, signatures, so crypetr use common code, be creative, and go as dynamic as possible. Where can I find info about making a good crypter.

This depends on how the RAT was developed. HowToHack subscribe unsubscribereaders users here now Welcome!


Welcome to Reddit, the front page of the internet. It isn’t difficult to bypass heuristic analysis, as long as you understand how it works. I don’t know how to make a crypter using a unique stub, cryptsr or possibly suggest an alternative to avoid AV detection.


Once you have the crypter, it’s very simple to just package your malware and deploy it.

It’s not like you’re going to distribute the key with the binary! Invoke null, null ; while the RunPE method’s complexity stays the same as native crypters. How do I make my rat exe FUD? Want to add rud the discussion? Try to not trigger behavioural shields by not doing something incredibly suspicious.

I would go with that first. So to solve your problem, using an existing RAT or not needing to constantly rcypter the code is a much more favourable option because it increases your efficiency to infect more users. 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.

NET binary because they require dependencies to ffud which are not shared with native executables however, the RunPE method is still relatively simple.

How to create an FUD rat. I am an IT guy who wanted to do computer science but ended up with biology. Encryption is a big part of crypters, hence the name.
