230 million distinct cloud environments are the target of a massive cyberattack on AWS. Unit 42 researchers uncovered a clever, massive scheme to blackmail numerous firms using cloud technologies.
Over 230 million distinct cloud settings are the focus of this big, wide-scale cyberattack on AWS, according to security specialists. Researchers from Unit 42 discovered a sophisticated, extensive effort that used cloud technology to control and extort many corporations. The attackers devised a cunning plan to take advantage of cloud infrastructures’ accessible environment variable (.env) files. These.env files, which were frequently disregarded by security measures, held private information like access codes to various services and programs. As a result, the hackers were able to access the victims’ systems without authorization and continue their infiltration of the networks.
The threat actors broke into exposed.env files that held important data by using automated methods to search for millions of domains. After entering, they immediately began using AWS API requests like GetCallerIdentity, ListUsers, and ListBuckets to conduct a thorough reconnaissance of the compromised environments. Subsequently, the actors enhanced their rights by creating new IAM roles with complete administrative privileges, demonstrating their thorough understanding of AWS IAM components. They then went ahead and used Lambda functions that were maliciously created to run recursive searches for additional.env files in other AWS locations, with a special emphasis on Mailgun credentials that might be used in a massive phishing attack.
With over 230 million unique endpoints on the target list and access to.env files in over 110,000 domains, the campaign’s enormous reach was evident. Data exfiltration into attacker-controlled S3 buckets marked the end of the operation. Such advanced attack strategies emphasize how crucial it is to put strong IAM policies in place, monitor cloud activity constantly, and adhere to a very strict security policy for configuration files in order to prevent unauthorized access and minimize the risk of data loss or leakage in cloud environments.
“The original IAM credential used to obtain initial access to the cloud environment did not have administrator access to all cloud resources, as discovered by the threat actor during their discovery operations. We observed that the attackers were able to attach IAM policies to pre-existing roles and establish new ones since they were able to access the original IAM role that was utilized for accessing the system.

This cloud-based extortion scheme exposed sophisticated operational security and data exfiltration techniques. The attackers used the S3 Browser to their advantage to perform certain API calls that revealed their activities without requiring object-level logging. It’s crucial to remember that exfiltration could be found by looking for spikes in GetObject and DeleteObject activities in Cost and Usage Reports. Following the process of data exfiltration and deletion, the attackers published ransom notes to the empty S3 buckets, requesting payment in order to stop data leaks and maybe restore erased data.
