What is NTPacker?

NTPacker is a program that will crypt a file so that it will become undetected by AV's.

How does NTPacker work?

The file that is selected will be crypted and packed at the EOF of the stub. Once the created file is run, the stub will read the data

from the end of the file and write it into a process that is chosen.

There are 3 different types on encryption to use:

aPlib - Compresses the server and will then crypt it. This is the most popular method and is still undetected by the majority of AV's.

An AV may be able to detect the aPlib compressed server. This method is also used by MicroJoiner.

XOR - XOR will crypt the server with a random value (9 bytes - eg. ECA123BCD). This will make the file undetected. Please note

that this will be detected if the stub that you use is detected.

aPlib + XOR - Compresses the file with both aPlib and XOR. The file will first be compressed with aPlib and then encrypted by XOR. This

will make the file undetected, again, aslong as the stub is undetected too.
