Background for this topic.
Amazon Web Services (AWS) is a cloud platform offering on-demand computing, storage, databases, networking, and managed services. Organizations use it to run applications and process data without operating the underlying physical infrastructure. Security reporting under this tag may concern AWS service flaws, its infrastructure, or weaknesses in customer-configured environments.
AWS follows a shared-responsibility model: AWS secures the cloud infrastructure, while customers must secure identities, data, configurations, and workloads. Material risks include overly broad IAM permissions or stolen credentials, publicly exposed storage or network services, and unpatched virtual machines, containers, or application interfaces. Effective defenses include least-privilege access, encryption, configuration review, timely patching, and centralized audit logging through services such as CloudTrail. Those logs and related telemetry support detection and investigation, while predefined procedures can revoke credentials, isolate workloads, and preserve evidence when an account or resource is compromised.
Threat Actor 'Codefinger' Targets Cloud EnvironmentsA ransomware group is targeting Amazon S3 buckets, exploiting the data stored there using AWS’s server-side encryption with customer keys and demanding a ransom in exchange for the encryption key needed to unlock the data. The group uses compromised or publicly exposed AWS account credentials.
A new ransomware campaign encrypts Amazon S3 buckets using AWS's Server-Side Encryption with Customer Provided Keys (SSE-C) known only to the threat actor, demanding ransoms to receive the decryption key. [...]
'Codefinger' crims on the hunt for compromised keys A new ransomware crew dubbed Codefinger targets AWS S3 buckets and uses the cloud giant's own server-side encryption with customer provided keys (SSE-C) to lock up victims' data before demanding a ransom payment for the symmetric AES-256 keys required to decrypt it.…
