Apple macOS Bug Reveals Passwords for APFS Encrypted Volumes in Plaintext

Apple macOS Bug Reveals Passwords for APFS Encrypted Volumes in Plaintext

Mar 29, 2018
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

Apple macOS High Sierra Bug Exposes Passwords of Encrypted APFS Volumes As Hint

Oct 06, 2017
A severe programming error has been discovered in Apple's latest macOS High Sierra 10.13 that exposes passwords of encrypted Apple File System (APFS) volumes in plain text. Reported by Matheus Mariano, a Brazilian software developer, the vulnerability affects encrypted volumes using APFS wherein the password hint section is showing the actual password in the plain text. Yes, you got that right—your Mac mistakenly reveals the actual password instead of the password hint. In September, Apple released macOS High Sierra 10.13 with APFS (Apple File System) as the default file system for solid-state drives (SSDs) and other all-flash storage devices, promising strong encryption and better performance. Mariano discovered the security issue while he was using the Disk Utility in macOS High Sierra to add a new encrypted APFS volume to a container. When adding a new volume, he was asked to set a password and, optionally, write a hint for it. So, whenever the new volume is mounted, m

New Report: Unveiling the Threat of Malicious Browser Extensions

Dec 06, 2023Browser Security / Privacy
Compromising the browser is a high-return target for adversaries. Browser extensions, which are small software modules that are added to the browser and can enhance browsing experiences, have become a popular browser attack vector. This is because they are widely adopted among users and can easily turn malicious through developer actions or attacks on legitimate extensions. Recent incidents like  DataSpii  and the  Nigelthorn  malware attack have exposed the extent of damage that malicious extensions can inflict. In both cases, users innocently installed extensions that compromised their privacy and security. The underlying issue lies in the permissions granted to extensions. These permissions, often excessive and lacking granularity, allow attackers to exploit them. What can organizations do to protect themselves from the risks of browser extensions without barring them from use altogether (an act that would be nearly impossible to enforce)?  A new report by LayerX, "Unveiling the
