  • Abnormal Allocation of compute resources in multiple regions Informational Cloud 4 variations

    An identity allocated an unusual compute resource pool, suspected as mining activity.

    Activation:
    14 Days
    Training:
    30 Days
    Test:
    30 Minutes
    Deduplication:
    5 Days
    ATT&CK tactics: Impact (TA0040) Initial Access (TA0001)
    ATT&CK techniques: Resource Hijacking (T1496) Valid Accounts (T1078)
    Required data: AWS Audit Log Gcp Audit Log
    Attacker's goals: Leverage cloud compute resources to generate virtual currency.
    Investigative actions: Verify that the identity creating the resources is legitimate. Check for unusual behavior from this identity, including potential compromise (e.g., exposed access keys or service accounts).

  • Allocation of multiple cloud compute resources Informational Cloud 5 variations

    An identity allocated multiple compute resources.

    Activation:
    14 Days
    Training:
    30 Days
    Test:
    1 Hour
    Deduplication:
    5 Days
    ATT&CK tactics: Impact (TA0040) Initial Access (TA0001)
    ATT&CK techniques: Resource Hijacking (T1496) Valid Accounts (T1078)
    Required data: AWS Audit Log Azure Audit Log Gcp Audit Log
    Attacker's goals: Leverage cloud compute resources to earn virtual currency.
    Investigative actions: Check the identity created resources and its legitimacy. Look for any unusual behavior originated from the suspected identity, and check if they're compromised, e.g. Access key, service account, etc.

    Variations

    Unusual allocation of multiple cloud compute resources

    High overridden

    An identity allocated multiple compute resources.This activity is highly unusual, such volume of compute allocation was not seen across all the projects during the past 30 days. overridden

    Unusual allocation of multiple cloud compute resources

    Medium overridden

    An identity allocated multiple compute resources.This activity is highly unusual, such volume of compute allocation was not seen at in this project during the past 30 days. overridden

    Unusual allocation of multiple cloud compute resources

    Medium overridden

    An identity allocated multiple compute resources.The allocated instances contains GPU accelerators, such pattern is related to a crypto mining activity. overridden

    Allocation of multiple cloud compute resources with accelerator gear

    Low overridden

    An identity allocated multiple compute resources.his activity is unusual for this identity in past 30 days. overridden

    Unusual allocation attempt of multiple cloud compute resources

    Low overridden

    An identity attempted to allocate multiple compute resources.This activity is highly unusual, such volume of compute allocation was not seen at in this project during the past 30 days. overridden

  • Suspicious heavy allocation of compute resources - possible mining activity Medium Cloud 3 variations

    An identity allocated an unusual heavy compute resource, suspected as mining activity.Heavy machines normally have a high amount of CPU cores or attached with GPU, which are targeted by adversaries to mine Cryptocurrency.
