We also noticed that it has some unused variables that might just be included for use in later versions. As soon as this script is triggered, it sets the attributes of files in that current directory to read-only and hidden , just like the previous script.

The script then performs different checks and makes modifications to system configuration and registry values.

It checks if it is running inside virtual machines or sandboxed applications and if so, it terminates. Otherwise, it disables UAC, system restore points, and task manager and then adds a Windows Update key to the registry and startup for persistency.

Finally, if the config file has a URL, it downloads the payload from there. If the config file has raw PE data, it gets a payload from there and injects it into the process memory of RegSvcs.

Below are a few images of the code from the script that we de-obfuscated, cleaned, and renamed functions and variables to show the functionality. The functions are not in exact order, instead, they are presented as below for easy understanding.

The first call to Pastebin downloads a. Following a de-obfuscation of the script we identified a couple of interesting new additions:. Persistence through a shortcut in the start-up directory:.

In previous versions, we identified the use of simplistic RunPE for injection and hollowing of the NanoCore. However, in the current version, the shellcode was adjusted to implement known methods of bypass and evading hooks by remapping the relevant executables from the knownDlls section. The compiled NanoCore client embeds the encrypted plugins and settings as part of its file resources.

This research further exposes the tendency of adversaries to abuse memory for the execution of known RAT families that are otherwise easily detected when downloaded to disk.

We also see a drastic increase in sophistication over the last year through moving more and more of the attack stages into the memory while using a legitimate Windows process to bypass whitelisting.

The only possible way to cope with such risk is by looking at things differently by applying preventive measures. Morphisec prevents all the described attacks by applying Moving target defense on the process memory.
