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.
Blighty’s latest stab at encryption? A secret order to pry open iCloud, sources claim The UK's Home Office refuses to either confirm or deny reports that it recently ordered Apple to create a backdoor allowing the government to access any user's cloud data.…
Secret Order Seeks to Compel Apple to Weaken Encryption, Washington Post ReportsThe British government has unexpectedly reignited the long-running encryption debate, reportedly issuing a secret order to Apple requiring that it provide direct access to global users' fully encrypted cloud backups and prohibited the technology giant from alerting any targeted accountholders.
A new audit of DeepSeek's mobile app for the Apple iOS operating system has found glaring security issues, the foremost being that it sends sensitive data over the internet sans any encryption, exposing it to interception and manipulation attacks
New mobile apps from the Chinese artificial intelligence (AI) company DeepSeek have remained among the top three "free" downloads for Apple and Google devices since their debut on Jan. 25, 2025. But experts caution that many of DeepSeek's design choices -- such as using hard-coded encryption keys, and sending unencrypted user and device data to Chinese companies -- introduce a number of glaring security and privacy risks.
A security vulnerability has been disclosed in AMD's Secure Encrypted Virtualization (SEV) that could permit an attacker to load a malicious CPU microcode under specific conditions
