Analysis Advice
Sample drops PE files which have not been started, submit dropped PE samples for a secondary analysis to Joe Sandbox |
Sample is a service DLL but no service has been registered |
Sample tries to load a library which is not present or installed on the analysis machine, adding the library might reveal more behavior |
Sample may offer command line options, please run it with the 'Execute binary with arguments' cookbook (it's possible that the command line switches require additional characters like: "-", "/", "--") |
