The sources discuss several cybersecurity topics, including zero-day vulnerabilities in Apple products, a new security measure implemented by Bitwarden to protect password vaults, and a cyberattack against the DeepSeek AI platform. The Apple zero-day, tracked as CVE-2025-24085, is a privilege escalation flaw in the Core Media framework that has been actively exploited. Bitwarden is now requiring email verification for logins from unrecognized devices if users do not have two-factor authentication enabled. DeepSeek, a Chinese AI platform, has halted new signups due to a large-scale cyberattack, believed to be a DDoS attack.
