In our risk register, what severity level and impact category should be assigned when the Modify System Image technique is determined to be applicable to target network devices?
| Checked | Without skill | With skill |
|---|---|---|
| Assigns a Low severity rating to the applicability finding. | Missed | Passed |
| Classifies the impact under Defense Evasion. | Missed | Passed |

Adversaries may make changes to the operating system of embedded network devices to weaken defenses and provide new capabilities for themselves. On such devices, the operating systems are typically monolithic and most of the device functionality and capabilities are contained within a single file.
To change the operating system, the adversary typically only needs to affect this one file, replacing or modifying it. This can either be done live in memory during system runtime for immediate effect, or in storage to implement the change on the next boot of the network device.
Platforms: Network Devices
Identify Attack Surface: Determine if the target environment is susceptible to Modify System Image by examining the target platforms (Network Devices).
Assess Existing Defenses: Review whether mitigations for T1601 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.
Use multi-factor authentication for user and privileged accounts. Most embedded network devices support TACACS+ and/or RADIUS. Follow vendor prescribed best practices for hardening access control.
