Securing Amazon S3 Data Against Ransomware Attacks

Your S3 data is vulnerable to ransomware attacks

Amazon S3 is a popular choice for businesses due to its high availability, durability and cost-effectiveness. And its use is growing even more as organizations rely on AWS S3 as the foundation of their Gen AI data lakes.

This widespread use and the storage of critical data make S3 an attractive target for threat actors. The risk of threat actors compromising S3 data is significant, as it can serve as both an entry point and a distribution point for ransomware.

An example S3 threat pathway is when an attacker identifies a misconfigured S3 bucket that is publicly accessible or has weak access controls and uploads ransomware to it. Then a legitimate user unknowingly accesses the malicious file, leading to encryption of local and network files, operational disruption, and potential data loss.

To secure against such attacks, it is crucial to tighten IAM controls and implement preventative measures, but also continuously verify the integrity of your data to promptly identify any compromises when they (almost inevitably) occur. 

Secure Your S3 Data 

Given this significant risk, Elastio customers asked us to extend our ransomware protection to continuously inspect their S3 data for ransomware and malware. This way, customers can be quickly alerted to any compromises and remediate threats before they spread. Elastio performs inspections both on the live data and on AWS Backups to ensure both early detection and clean recoveries from uncompromised backups.

Elastio S3 Ransomware & Malware Protection

Elastio offers the most comprehensive and flexible enterprise ransomware and malware protection for S3 – and at the lowest cost.

With Elastio, customers can perform an initial inspection of all their existing S3 data upon deployment to ensure it is free from ransomware and malware. As new objects are added to your S3 buckets, Elastio automatically and continuously inspects them for any threats, providing ongoing protection.  Additionally, Elastio enables periodic full inspections using the latest ransomware models and malware signatures to identify threats that were unknown during previous scans.  Another key benefit is Elastio’s seamless integration with AWS Backup to ensure your S3 backups remain clean and uncompromised.

With our most recent release, customers can now inspect even larger buckets for ransomware and malware without impacting production.  Elastio’s license is priced based on the amount of storage protected rather than by scan, enabling regular, comprehensive scans without high costs, significantly enhancing your overall security posture.
