A threat actor used compromised Qubole IAM credentials to reach into tens of customers' AWS environments, stealing secrets and downloading S3 data between Oct 14 and 26, according to research by Wiz and Sentra. The campaign targeted accounts whose cross-account IAM roles trust Qubole's AWS account.

Wiz says the attacker compromised two Qubole IAM users and assumed otherwise unused roles, then called AWS STS AssumeRole to obtain temporary credentials. From inside those roles, the intruder surveyed resources, read AWS Secrets Manager and SSM Parameter Store secrets, inspected Lambda environment variables, and validated keys with TruffleHog.

The access pattern was consistent: assume a role, list buckets, enumerate objects, then download them. Sentra confirmed dozens of victims and millions of files stolen from one customer alone, at a rate of about 100 passwords and keys in seven minutes. AWS said its services operated as designed and were not compromised.

Affected administrators should review CloudTrail from Oct 1 onward for access from Qubole's AWS account, investigate later secret and S3 access, rotate exposed credentials, revoke active role sessions, and remove unused integrations. The report does not identify how the Qubole accounts were first compromised or give an exact victim total.

## Evidence and scope

- Affected versions: Not established by supplied evidence
- Fixed versions: Not established by supplied evidence
- Exploitation: Known exploitation observed Oct 14–26 across tens of customer AWS environments; attacker accessed secrets and downloaded S3 data (E1 Q1/Q4).
- Limitations: The report does not specify how the Qubole accounts were compromised or the exact number of downstream victims; no public Qubole announcement was found and BleepingComputer was awaiting Qubole's response (E1 Q4/Q5).
