![]() The action of calling the interface and operation runs the procedure. ![]() If an IT administrator wants to perform a procedure (such as creating a service with SCM on a remote server) the administrator's client sends an RPC request to call the specific interface and operation (svcctl:CreateServiceW) on the server. Operations are similar to procedure commands. For example, the SCM has an interface (svcctl) with operations (such as CreateServiceW). Remote procedure call (RPC), which is a network protocol that enables communication between a client and server.The SCM manages programs and services that run on Windows devices. Service Control Manager (SCM), which is located on Windows clients and servers.Only users with administrative privileges can access ADMIN$. ADMIN$ share, which is a hidden share located on Windows devices.Launching a service includes these components: PsExec requires the IT administrator to launch a system service. PsExec is a Windows Sysinternals utility that enables IT administrators to run commands and executable binary files on remote servers. ![]() So how does the attacker compromise the credit card server, laterally moving from the workstation to the server, while remaining undetected? One option is to launch a legitimate remote administration tool with a system service, such as PsExec. Now inside the network, the attacker wants to find and access a server with credit card information. Through a phishing email campaign, a company employee inadvertently installs malware on their Windows workstation, giving the attacker access to that workstation. But these tools also make life easier for attackers who want to run commands on, and compromise, other devices within a network.Ĭonsider this scenario: an attacker wants to steal credit card numbers from a company that manages financial transactions. From one location, an administrator can remotely deploy updates, run programs, or run commands on several network devices. Remote administration tools make life easier for IT administrators.
