The RAT binary is downloaded and put in onto an individual’s machine with help from the ‘msiexec’ command inside the Dwelling home windows Installer service.
In a model new report, the researchers at Palo Alto Networks’ Unit 42 outlined that the MSI payload installs with none warnings and gives a PowerShell script inside the Dwelling home windows temp folder. That’s used for persistence and the script performs the place of a backup reply for placing in NetSupport Supervisor.
Sooner than the script continues its operations, it checks to see if an antivirus from each Avast or AVG is put in on the system. If this is so, it stops engaged on the sufferer’s laptop computer. If the script finds that these purposes aren’t present on the machine, it gives the recordsdata wished b NetSupport Supervisor to a folder with a random title and likewise creates a registry key for the first executable named ‘presentationhost.exe’ for persistence.
