Storm-1977 is a threat actor targeting cloud environments in the education sector for cryptocurrency mining.
Analyst brief
Storm-1977 is a sophisticated threat actor targeting cloud tenants, predominantly in the education sector, using the AzureChecker.exe CLI tool as their primary infection vector for password-spraying attacks. They have compromised over 200 containers, repurposing them for cryptocurrency mining by leveraging guest accounts to create new resource groups within compromised subscriptions. Defenders should enforce multi-factor authentication to counter password-spraying, monitor for anomalous guest account activities, and strengthen controls against unauthorized container and resource group creation.
