Wiz says stolen Qubole AWS IAM keys hit customer accounts
Wiz said an attacker used compromised Qubole AWS IAM users to assume leftover customer roles and steal secrets and S3 data from Oct. 14-26, BleepingComputer reported; The Hacker News carried the same Wiz account.
An attacker used compromised identity credentials on Qubole's AWS account to assume leftover IAM roles in customer clouds and steal secrets and object storage data between Oct. 14 and Oct. 26, cloud security firm Wiz said, according to BleepingComputer and The Hacker News1,2.
Qubole is a big-data platform whose AWS account some customers had configured to trust via IAM roles, a pattern Wiz said providers use with AWS STS AssumeRole for temporary access1. Wiz found the attacker had compromised two Qubole IAM users and assumed otherwise unused roles in multiple customer accounts1.
Wiz said the actor then surveyed resources, pulled secrets from AWS Secrets Manager and SSM Parameter Store, read Lambda environment variables, and used TruffleHog to validate AWS keys, Microsoft Entra ID client secrets, and Okta credentials1. Downloads from reachable S3 buckets followed an opportunistic pattern: assume a role, list buckets and objects, then GetObject1.
Wiz did not specify how the Qubole users were compromised or give a full victim count1. Sentra, which Wiz said helped start the inquiry after seeing suspicious activity, said there were dozens of victims and millions of files stolen from one customer, and that secrets were collected at a rate of 100 passwords and keys in seven minutes1. Mandiant also took part in the investigation, BleepingComputer reported1.
The Hacker News account, dated a day earlier in desk metadata, restated Wiz's finding that multiple Qubole customer AWS accounts were broken into in that window and that stored secrets and data were stolen2. It did not, in the text retrieved for this filing, repeat Sentra's scale figures2.
BleepingComputer said it found no public Qubole statement and had emailed the company1. Wiz advised reviewing CloudTrail from Oct. 1 for access from Qubole's AWS account, rotating exposed credentials, revoking role sessions, and tightening or removing unused cross-account roles1.
