Adversaries may target protection function alarms to prevent them from notifying operators of critical conditions. Alarm messages may be a part of an overall reporting system and of particular interest for adversaries. Disruption of the alarm system does not imply the disruption of the reporting system as a whole.
A Secura presentation on targeting OT notes a dual fold goal for adversaries attempting alarm suppression: prevent outgoing alarms from being raised and prevent incoming alarms from being responded to. The method of suppression may greatly depend on the type of alarm in question:
In ICS environments, the adversary may have to suppress or contend with multiple alarms and/or alarm propagation to achieve a specific goal to evade detection or prevent intended responses from occurring. Methods of suppression may involve tampering or altering device displays and logs, modifying in memory code to fixed values, or even tampering with assembly level instruction code.
Platforms: ICS
Determine if the target ICS/SCADA environment is susceptible to Alarm Suppression by examining operational technology systems and network architecture.
Review whether mitigations for T0878 are in place. If defenses are absent or misconfigured, this technique may be exploitable in the ICS environment.
