NamesN1stAgent
CategoryMalware
TypeBackdoor
Description(Palo Alto) N1stAgent requires specific arguments to execute successfully. Some samples check only for one argument and others check for three different arguments where each one is either executing the malware, sets a startup key and runs the malware or installs the malware as a service. Service installation was not working in our found samples because the author seems to be forgotten to install the service with arguments.
