Breaking RSA with a Quantum Computer
January 4 2023A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously....

Breaking the Zeppelin Ransomware Encryption Scheme
November 21 2022Brian 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...

NIST’s Post-Quantum Cryptography Standards
August 8 2022Quantum computing is a completely new paradigm for computers. A quantum computer uses quantum properties such as superposition, which allows a qubit (a quantum bit) to be neither 0...
Read moreSIKE Broken
August 4 2022SIKE 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...

ENCSecurity markets a file encryption system, and it’s used by SanDisk, Sony, Lexar, and probably others. Despite it using AES as its algorithm, its implementation is flawed in multiple...
Read moreBreaking RSA through Insufficiently Random Primes
March 16 2022Basically, the SafeZone library doesn’t sufficiently randomize the two prime numbers it used to generate RSA keys. They’re too close to each other, which makes them vulnerable to...
Read moreSamsung Encryption Flaw
March 4 2022Researchers 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...

Decrypting Hive Ransomware Data
March 1 2022Nice 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...

Bunnie Huang’s Plausibly Deniable Database
February 10 2022Bunnie Huang has created a Plausibly Deniable Database.
Most security schemes facilitate the coercive processes of an attacker because they disclose metadata about the secret data, such as the...
