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.
This scale of this month's encrypted DDoS attack over HTTPS suggests a well-resourced operation, analysts say.
The cybercriminals trash files larger than 2MB, forever losing them to the void Ransomware groups in recent years have ramped up the threats against victims to incentivize them to pay the ransom in return for their stolen and encrypted data. But a new crew is essentially destroying files larger than 2MB, so data in those files is lost even if the ransom is paid.…
Encryption will break, so it's important to mix and layer different encryption methods.
Elon Musk, CEO of SpaceX and Tesla and Twitter's new owner, on Thursday called on adding support for end-to-end encryption (E2EE) to the platform's direct messages (DM) feature
A new Onyx ransomware operation is destroying large files instead of encrypting them, preventing those files from being decrypted even if a ransom is paid. [...]
