What is DCE services enumeration?

Description. By sending a Lookup request to the portmapper (TCP 135 or epmapper PIPE) it was possible to enumerate the Distributed Computing Environment (DCE) services running on the remote port. Using this information it is possible to connect and bind to each service by sending an RPC request to the remote port/pipe.

What is DCE RPC or MSRPC services?

Distributed Computing Environment / Remote Procedure Calls (DCE/RPC) or MSRPC services running. on the remote host can be enumerated by connecting on port 135 and doing the appropriate queries. The actual reporting takes place in the NVT ‘DCE/RPC and MSRPC Services Enumeration Reporting’

What is DCE RPC protocol?

DCE/RPC is a specification for a remote procedure call mechanism that defines both APIs and an over-the-network protocol. A DCE/RPC server’s endpoint mapper (EPMAP) will listen for incoming calls. A client will call this endpoint mapper and ask for a specific interface, which will be accessed on a different connection.

What is MSRPC service?

MSRPC is an interprocess communication (IPC) mechanism that allows client/server software communcation. That process can be on the same computer, on the local network (LAN), or across the Internet. Its purpose is to provide a common interface between applications.

What is DCE endpoint?

The Microsoft DCE Locator service is also known as the end-point mapper. It works like a Sun RPC portmapper, except that end-points can also be named pipes. Microsoft relies upon DCE RPC to remotely manage services. Some services that use port 135 of end-point mapping are: DHCP server.

What is the primary goal of DCE?

DCE provides the key services required for supporting distributed applications, including: support for remote procedure call (RPC) between clients and servers; a directory service to let clients find servers; and security services to ensure secure access between clients and servers.

Is MSRPC malicious?

Originally published November 10, 2021 . Last modified November 17, 2021. Microsoft Remote Procedure Call (MSRPC) is an interprocess communication protocol mechanism that adversaries can abuse to perform a wide range of malicious actions.

What is DCE RPC port?

Is DCE an operating system?

An enabling platform for building solutions, the DCE technology was designed to operate independently of the operating system and networking technology that applications use. As a result, it enables interaction between clients and servers in just about any type of environment an organization may have in place.

What is meant by DCE?

A data circuit-terminating equipment (DCE) is a device that sits between the data terminal equipment (DTE) and a data transmission circuit. It is also called data communication(s) equipment and data carrier equipment. Usually, the DTE device is the terminal (or computer), and the DCE is a modem.
