How to Defend Amazon S3 Buckets from Ransomware Exploiting SSE-C Encryption
A new ransomware campaign, dubbed Codefinger, has been targeting Amazon S3 users by exploiting compromised AWS credentials to encrypt data using Server-Side Encryption with Customer-Provided Keys (SSE-C). Attackers then demand ransom payments for the symmetric AES-256 keys required to decrypt the data. AWS has released recommendations to help users mitigate the risk of ransomware attacks on S3.
AWS Reduces Latency and Costs for Key/Value Datastores with AZ Affinity Routing and GLIDE Valkey
AWS recently introduced Availability Zone (AZ) awareness in version 1.2 of the open source Valkey General Language Independent Driver for Enterprise (GLIDE) client library. By implementing AZ affinity routing in the open source key/value datastore, developers can reduce latency and costs by directing requests to replicas within the same AZ as the client.
