Breaking the Zeppelin Ransomware Encryption Scheme

Source

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 …

Amid backlash from privacy advocates, Meta expands end-to-end encryption trial

Source

Enlarge (credit: Getty Images) Meta is ever so slowly expanding its trial of end-to-end encryption in a bid to protect users from snoops and law enforcement. End-to-end encryption, often abbreviated as E2EE, uses strong cryptography to encrypt messages with a key that is unique to each user. Because the …

SIKE Broken

Source

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 …

Enable post-quantum key exchange in QUIC with the s2n-quic library

Source

At Amazon Web Services (AWS) we prioritize security, performance, and strong encryption in our cloud services. In order to be prepared for quantum computer advancements, we’ve been investigating the use of quantum-safe algorithms for key exchange in the TLS protocol. In this blog post, we’ll first bring …

Facebook Is Now Encrypting Links to Prevent URL Stripping

Source

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 …

End-to-end encryption’s central role in modern self-defense

Source

Enlarge (credit: Getty Images ) A number of course-altering US Supreme Court decisions last month—including the reversal of a constitutional right to abortion and the overturning of a century-old limit on certain firearms permits—have activists and average Americans around the country anticipating the fallout for rights and privacy …

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

Source

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 …

AWS is pleased to announce that Wickr for Government (WickrGov) has achieved Federal Risk and Authorization Management Program (FedRAMP) Ready status at the Moderate Impact Level, and is actively working toward FedRAMP Authorized status. FedRAMP is a US government-wide program that promotes the adoption of secure cloud services across …

How to use AWS KMS RSA keys for offline encryption

Source

This blog post discusses how you can use AWS Key Management Service (AWS KMS) RSA public keys on end clients or devices and encrypt data, then subsequently decrypt data by using private keys that are secured in AWS KMS. Asymmetric cryptography is a cryptographic system that uses key pairs …

Forging Australian Driver’s Licenses

Source

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 …

The NSA Says that There are No Known Flaws in NIST’s Quantum-Resistant Algorithms

Source

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 …

Samsung Encryption Flaw

Source

Researchers have found a major encryption flaw in 100 million Samsung Galaxy phones. From the abstract: In this work, we expose the cryptographic design and implementation of Android’s Hardware-Backed Keystore in Samsung’s Galaxy S8, S9, S10, S20, and S21 flagship devices. We reversed-engineered and provide a detailed …

Decrypting Hive Ransomware Data

Source

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 …

Introducing s2n-quic, a new open-source QUIC protocol implementation in Rust

Source

At Amazon Web Services (AWS), security, high performance, and strong encryption for everyone are top priorities for all our services. With these priorities in mind, less than a year after QUIC ratification in the Internet Engineering Task Force (IETF), we are introducing support for the QUIC protocol which can …

New DeadBolt Ransomware Targets NAT Devices

Source

There’s a new ransomware that targets NAT devices made by QNAP: The attacks started today, January 25th, with QNAP devices suddenly finding their files encrypted and file names appended with a.deadbolt file extension. Instead of creating ransom notes in each folder on the device, the QNAP device …

How to use tokenization to improve data security and reduce audit scope
