Similarly, the rootkit checks if the system registry contains an entry for the malicious service and restores it if necessary.

Later modifications of the rootkit randomly select and infect system drivers which meet certain criteria. In order to prevent detection by anti-rootkit tools which check the file size at high- and low-level, the file is infected in such a way so that the size does not change. Entry point in atapi. TDL-3 uses its own implementation of an encrypted file system in which it saves its configuration data and additional user-mode DLLs.

In order to do this, TDL-3 spoofs the object servicing a system device. Disk device stack All functions servicing this device lead to one thing: In this way, the rootkit filters attempts to access disk sectors where critical data is located. If an attempt is made to read an infected driver in this case, atapi.
