How can I make clean malware?

[Dfint01]

If I use remote access tools for example like : XWorm, VenomRAT ...etc.
How can I turn the trojan into Fully Undetectable Payload (FUD).

Depending on the trojan you may use an obfuscator, this may help.

A crypter is what you seek!

if you need i have crypter + stub for .NET compiler like vb. net and c# using aes encryption & stub use runtime encryption techniques run all code on memory without on hard disks if you want contact me of course not for free

Another option is to buy the remote tools directly from the developers instead of using public RATs, as most developers offer crypting services or offer contacts for such services, and some directly purchased remote tool builds normally have 3-0 detection rates against AV engines.
