Background for this topic.
Encryption transforms readable data into ciphertext using an algorithm and a key, so someone who obtains the ciphertext cannot normally understand it without the required key. It protects confidentiality for data in transit, such as traffic between services, and at rest, such as files, databases, and backups. Encryption does not by itself prove who sent data, prevent tampering, or protect plaintext displayed on a compromised endpoint.
Its security therefore depends on implementation and key management. Attackers may target stolen, exposed, or overprivileged keys, weak algorithms or protocols, poor randomness, and systems that decrypt data unnecessarily. Use modern, authenticated encryption where appropriate; protect keys separately from encrypted data with tightly limited access, rotation and revocation procedures, and monitored use. Verify that encryption covers relevant backups and internal service links, while recognizing that lost keys can make recovery impossible and that encrypted traffic may still reveal metadata such as timing or endpoints.
Amateurish Ransomware Group Doubles as HackstivistsCybersecurity researchers discovered an artificial intelligence-driven ransomware group that emerged at the end of last year and compromised more than 85 victims worldwide. The group uses double extortion, combining data theft with encryption.
Threat Actor 'Codefinger' Targets Cloud EnvironmentsA ransomware group is targeting Amazon S3 buckets, exploiting the data stored there using AWS’s server-side encryption with customer keys and demanding a ransom in exchange for the encryption key needed to unlock the data. The group uses compromised or publicly exposed AWS account credentials.
