DETECTION OVERVIEW

Unusual Remote Admin Connection Requests

Risk Factors

An attacker with network access and stolen credentials is likely to run a scan to learn if they can gain privileged access to other devices. Attack tools can make this scan relatively easy to perform. This type of reconnaissance does not negatively affect network performance, but the attacker can identify new target devices that they can access.

The system might change the risk score for this detection.

Attack Background

After stealing user credentials and infiltrating a network, an attacker runs a script that initiates SCM connection attempts across multiple devices simultaneously. Every Windows device has an SCM that enables administrators to remotely manage services. The script sends a Microsoft remote procedure call (MSRPC) to the SVCCTL interface. Next, the attacker analyzes the errors returned by each device and ignores devices that return ERROR_ACCESS_DENIED. Devices that allow the attacker to connect to the SCM are targeted for exploitation.

Mitigation Options

Implement network segmentation and the principle of least privilege to minimize the damage caused by a compromised device
