CAPEC-555 Metadata
Likelihood of Attack
Medium
Typical Severity
Very High
Overview
Summary
This pattern of attack involves an adversary that uses stolen credentials to leverage remote services such as RDP, telnet, SSH, and VNC to log into a system. Once access is gained, any number of malicious activities could be performed.
Prerequisites
No prerequisites listed.
Potential Solutions / Mitigations
Disable RDP, telnet, SSH and enable firewall rules to block such traffic. Limit users and accounts that have remote interactive login access. Remove the Local Administrators group from the list of groups allowed to login through RDP. Limit remote user permissions. Use remote desktop gateways and multifactor authentication for remote logins.

Related CAPECs
| CAPEC ID | Description |
|---|---|
| CAPEC-151 | Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials. |
| CAPEC-560 | An adversary guesses or obtains (i.e. steals or purchases) legitimate credentials (e.g. userID/password) to achieve authentication and to perform authorized actions under the guise of an authenticated user or service. |
