Suspicious heavy allocation of compute resources - possible mining activity

Synopsis

Field	Value
Activation Period	14 Days
Training Period	30 Days
Test Period	N/A (single event)
Deduplication Period	5 Days
Required Data	Requires one of the following data sources: AWS Audit Log OR Azure Audit Log OR Gcp Audit Log
Detection Modules	Cloud
ATT&CK Tactic	Impact (TA0040), Initial Access (TA0001)
ATT&CK Technique	Resource Hijacking (T1496), Valid Accounts (T1078)
Severity	Medium

Description

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.

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.
