Crypting

Crypting refers to encryption of your bot or RAT. There are two types of crypters available, FUD crypters and UD crypters. A bot herder or a RAT operator would need to have his .exe file encrypted so that anti- virus software wont detect the malicious malware. Most AV are aware of the .exe of a bot or a RAT and will immediately delete them. To avoid this a bot herder or bot operator would need to either FUD or UD his .exe. Most crypters have a private stub which is given to the buyer once he buys the crypter. The software is free and you can import the private stub purchased. Public crypters are worthless and can range from $30-$40. These are the worst type of crypters to purchase if you really want to have a long lasting bot or RAT. Private crypters are best because they are purchased with a private stub that is unique only to the buyer.



    FUD Crypters 

Fud crypters are FULLY UNDETECTABLE by anti-virus software hence the acronym FUD. FUD crypters can not stay FUD forever. So a bot herder or RAT operator has to update his .exe, usually after 2 weeks if the FUD crypter is good. These can run you from $150 - $700 for a good private FUD crypter with a AV scan of 0/34. see Glossary of Bots and Rats for further definitions.


   UD Crtpters 

UD crypters are Un Detectable by some anti-virus software. These crypters are usually available publicly and are basically worthless. But if you are on a tight budget then these can be efficient. These will run you like $30 - the most $80. The infection rate of your .exe will be %2(opinion basis not fact). For instance a AV scan will show results like 8/34. And this can be a problem if your looking to form a huge botnet.
