# T1496 - Resource Hijacking ## [Description from ATT&CK](https://attack.mitre.org/techniques/T1496)
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.(Citation: Sysdig Cryptojacking Proxyjacking 2023)
