A significant ransomware campaign has exploited over 1,200 unique AWS access keys to encrypt files in S3 storage buckets, leaving ransom notes demanding payment in Bitcoin. The attackers are using AWS's own encryption features to hide their activities, making it difficult for victims to detect breaches or recover their data.

Meredith Whittaker discusses the surprising reaction of people learning that Signal operates partly on AWS, emphasizing the importance of encryption that ensures user communications remain private and inaccessible to anyone, including AWS and Signal itself. She expresses concern over the public's lack of understanding regarding this aspect of Signal's infrastructure.
