Marriott admits it falsely claimed for five years it was using encryption during 2018 breach | CSO Online
Marriot revealed in a court case around a massive 2018 data breach that it had been using secure hash algorithm 1 and not the much more secure AES-1 encryption as it had earlier maintained.
Apple iOS 17.4: iMessage Gets Post-Quantum Encryption in New Update
Useful quantum computers aren’t a reality—yet. But in one of the biggest deployments of post-quantum encryption so far, Apple is bringing the technology to iMessage. #apple #computing #encryption #privacy #quantum #security
StripedFly: Perennially flying under the radar
Nobody would even suspect the mining malware was merely a mask, masquerading behind an intricate modular framework that supports both Linux and Windows. The amount of effort that went into creating the framework is truly remarkable, and its disclosure was quite astonishing.
“Please do not make it public”: Vulnerabilities in Sogou Keyboard encryption expose keypresses to network eavesdropping
- We analyzed Tencent’s Sogou Input Method, which, with over 450 million monthly active users, is the most popular Chinese input method in China. Analyzing the Windows, Android, and iOS versions of the software, we discovered troubling vulnerabilities in Sogou Input Method’s custom-designed “EncryptWall” encryption system and in how it encrypts sensitive data. We found that network transmissions containing sensitive data such as those containing users’ keystrokes are decipherable by a network eavesdropper, revealing what users are typing as they type. We disclosed these vulnerabilities to Sogou developers, who released fixed versions of the affected software as of July 20, 2023 (Windows version 13.7, Android version 11.26, and iOS version 11.25). These findings underscore the importance for software developers in China to use well-supported encryption implementations such as TLS instead of attempting to custom design their own.
PSA: upgrade your LUKS key derivation function
Here's an article from a French anarchist describing how his (encrypted) laptop was seized after he was arrested, and material from the encrypted partition has since been entered as evidence against him. His encryption password was supposedly greater than 20 characters and included a mixture of cases, numbers, and punctuation, so in the absence of any sort of opsec failures this implies that even relatively complex passwords can now be brute forced, and we should be transitioning to even more secure passphrases. Or does it? Let's go into what LUKS is doing in the first place. The actual data is typically encrypted with AES, an extremely popular and well-tested encryption algorithm. AES has no known major weaknesses and is not considered to be practically brute-forceable - at least, assuming you have a random key. Unfortunately it's not really practical to ask a user to type in 128 bits of binary every time they want to unlock their drive, so another approach has to be taken.
