What is RPC enumeration?

RPC enumeration is the process of discovering what services are running on what port numbers.

What is privilege escalation in Windows?

Privilege escalation is the process by which a user with limited access to IT systems can increase the scope and scale of their access permissions. For trusted users, privilege escalation allows expanded access for a limited time to complete specific tasks.

Is RpcSs needed?

What is MSRPC port used for?

What are RPC dynamic ports?

RPC dynamic port allocation instructs the RPC program to use a particular random port in the range configured for TCP and UDP, based on the implementation of the operating system used.

What is Rpcclient used for?

rpcclient is a utility initially developed to test MS-RPC functionality in Samba itself. It has undergone several stages of development and stability. Many system administrators have now written scripts around it to manage Windows NT clients from their UNIX workstation.

What are the two types of privilege escalation?

Read: The Remote Procedure Call Failed error for Windows Store apps.

Why RPC is faster than REST?

RPC helps make sending a request within services in the data center much more efficient than REST. If your services want to expose public APIs or create isolation, then using HTTP and REST API can provide more extensibility in your system. Anyone who knows HTTP from the standard documents will be able to use your APIs.

Is RPC TCP or UDP?

Generally, RPC applications will use UDP when sending data, and only fall back to TCP when the data to be transferred doesn’t fit into a single UDP datagram. Of course, client programs have to have a way to find out which port a program number maps to.

What port is DCOM?

Port 135

DCOM uses Port 135 to establish communication. Once the OPC Client and Server are able to communicate, they will negotiate new port numbers for communication dynamically.

What port is LDAP?

389
The standard port for LDAP communication is 389, although other ports can be used. For example, if you must be able to start the server as a regular user, use an unprivileged port, by default 1389. Port numbers less than 1024 require privileged access.

What port is DHCP?

UDP port 67
DHCP is a network protocol to used to configure IP networks. A DHCP server listens to UDP port 67 and dynamically assigns IP addresses and other network parameters to DHCP clients. These clients will listen for responses on UDP port 68.

Does RPC use TCP or UDP?

Why use RPC dynamic ports?

First, the RPC dynamic port range should be restricted to a smaller, more manageable port range that is easier to block by using a firewall or IPsec policy. By default, RPC dynamically allocates ports in the range of 1024 to 5000 for endpoints that do not specify a port on which to listen.

What is RPC over SMB?

The Remote Procedure Call Protocol Extensions, as specified in [MS-RPCE], define an RPC over SMB Protocol or SMB 2 Protocol sequence that can use SMB 2 Protocol named pipes as its underlying transport. The selection of protocol is based on client behavior during negotiation, as specified in section 1.7.

What is RPC for LSA?

LSARPC is really a set of calls, transmitted with RPC, to a system called the “Local Security Authority”. This used in the Microsoft/Windows world to perform management tasks on domain security policies from a remote machine. The protocol is described in MS-LSAD.
