APFS Encrypted Volume | Breaking Cybersecurity News | The Hacker News

Security researchers are warning of almost a decade old issue with one of the Apple's macOS feature which was designed for users' convenience but is potentially exposing the contents of files stored on password-protected encrypted drives. Earlier this month, security researcher Wojciech Regula from SecuRing published a blog post , about the "Quick Look" feature in macOS that helps users preview photos, documents files, or a folder without opening them. Regula explained that Quick Look feature generates thumbnails for each file/folder, giving users a convenient way to evaluate files before they open them. However, these cached thumbnails are stored on the computer's non-encrypted hard drive, at a known and unprotected location, even if those files/folders belong to an encrypted container, eventually revealing some of the content stored on encrypted drives. Patrick Wardle, chief research officer at Digital Security, equally shared the concern, saying tha

A severe programming bug has been found in APFS file system for macOS High Sierra operating system that exposes passwords of encrypted external drives in plain text. Introduced two years ago, APFS ( Apple File System ) is an optimized file system for flash and SSD-based storage solutions running MacOS, iOS, tvOS or WatchOS, and promises strong encryption and better performance. Discovered by forensic analyst Sarah Edwards, the bug leaves encryption password for a newly created APFS volume (e.g., encrypting USB drive using Disk Utility) in the unified logs in plaintext, as well as while encrypting previously created but unencrypted volumes. "Why is this a big deal? Well, passwords stored in plaintext can be discovered by anyone with unauthorized access to your machine, and malware can collect log files as well and send them off to someone with malicious intent," Edwards said. The password for an encrypted APFS volume can easily be retrieved by running following sim
