Resource Hijacking
Where this stands
One published detection covers this technique. Every one is unverified — no rule on Siemphony has been executed against real telemetry.
What the technique is
Adversaries may leverage the resources of co-opted systems to complete resource-intensive tasks, which may impact system and/or hosted service availability. Resource hijacking may take a number of different forms. For example, adversaries may: Leverage compute resources in order to mine cryptocurrency Sell network bandwidth to proxy networks Generate SMS traffic for profit Abuse cloud-based messaging services to send large quantities of spam messages In some cases, adversaries may leverage multiple types of Resource Hijacking at once.
