After way too many years, Apple is finally encrypting iCloud backups: Based on a screenshot from Apple, these categories are covered when you flip on Advanced Data Protection: device backups, messages backups, iCloud Drive, Notes, Photos, Reminders, Safari bookmarks, Siri Shortcuts, Voice Memos, and Wallet Passes. Apple says the only “major” categories not covered by … Read More “Apple Is Finally Encrypting iCloud Backups” »

Diplomatic code cracked after 500 years: In painstaking work backed by computers, Pierrot found “distinct families” of about 120 symbols used by Charles V. “Whole words are encrypted with a single symbol” and the emperor replaced vowels coming after consonants with marks, she said, an inspiration probably coming from Arabic. In another obstacle, he used … Read More “Charles V of Spain Secret Code Cracked” »

Breaking the Zeppelin Ransomware Encryption Scheme

Brian Krebs writes about how the Zeppelin ransomware encryption scheme was broken: The researchers said their break came when they understood that while Zeppelin used three different types of encryption keys to encrypt files, they could undo the whole scheme by factoring or computing just one of them: An ephemeral RSA-512 public key that is … Read More “Breaking the Zeppelin Ransomware Encryption Scheme” »

This is a dumb crypto mistake I had not previously encountered: A developer says it was possible to run their own software on the car infotainment hardware after discovering the vehicle’s manufacturer had secured its system using keys that were not only publicly known but had been lifted from programming examples. […] “Turns out the … Read More “Hyundai Uses Example Keys for Encryption System” »

SIKE Broken

SIKE is one of the new algorithms that NIST recently added to the post-quantum cryptography competition. It was just broken, really badly. We present an efficient key recovery attack on the Supersingular Isogeny Diffie­-Hellman protocol (SIDH), based on a “glue-and-split” theorem due to Kani. Our attack exploits the existence of a small non-scalar endomorphism on … Read More “SIKE Broken” »

Facebook Is Now Encrypting Links to Prevent URL Stripping

Some sites, including Facebook, add parameters to the web address for tracking purposes. These parameters have no functionality that is relevant to the user, but sites rely on them to track users across pages and properties. Mozilla introduced support for URL stripping in Firefox 102, which it launched in June 2022. Firefox removes tracking parameters … Read More “Facebook Is Now Encrypting Links to Prevent URL Stripping” »

NIST’s post-quantum computing cryptography standard process is entering its final phases. It announced the first four algorithms: For general encryption, used when we access secure websites, NIST has selected the CRYSTALS-Kyber algorithm. Among its advantages are comparatively small encryption keys that two parties can exchange easily, as well as its speed of operation. For digital … Read More “NIST Announces First Four Quantum-Resistant Cryptographic Algorithms” »

Forging Australian Driver’s Licenses

The New South Wales digital driver’s license has multiple implementation flaws that allow for easy forgeries. This file is encrypted using AES-256-CBC encryption combined with Base64 encoding. A 4-digit application PIN (which gets set during the initial onboarding when a user first instals the application) is the encryption password used to protect or encrypt the … Read More “Forging Australian Driver’s Licenses” »

Rob Joyce, the director of cybersecurity at the NSA, said so in an interview: The NSA already has classified quantum-resistant algorithms of its own that it developed over many years, said Joyce. But it didn’t enter any of its own in the contest. The agency’s mathematicians, however, worked with NIST to support the process, trying … Read More “The NSA Says that There are No Known Flaws in NIST’s Quantum-Resistant Algorithms” »

Decrypting Hive Ransomware Data

Nice piece of research: Abstract: Among the many types of malicious codes, ransomware poses a major threat. Ransomware encrypts data and demands a ransom in exchange for decryption. As data recovery is impossible if the encryption key is not obtained, some companies suffer from considerable damage, such as the payment of huge amounts of money … Read More “Decrypting Hive Ransomware Data” »
