A new ransomware strain called ShrinkLocker creates a new boot partition to encrypt corporate systems using Windows BitLocker.
The Kaspersky GERT has detected a VBS script that has been abusing Microsoft Windows features by modifying the system to lower the defenses and using the local MS BitLocker utility to encrypt entire drives and demand a ransom.

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.
Fixing newly discovered side channel will likely take a major toll on performance.
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.

Researchers have created a decryptor that exploits a flaw in Black Basta ransomware, allowing victims to recover their files for free.
Academic researchers developed a new attack called Terrapin that manipulates sequence numbers during the handshake process to breaks the SSH channel integrity when certain widely-used encryption modes are used.
The European telecom standards body behind a widely used radio encryption system will soon open-source its encryption protocols. The European Telecommunications
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.
A secret encryption cipher baked into radio systems used by critical infrastructure workers, police, and others around the world is finally seeing sunlight. Researchers say it isn’t pretty.
The US government warns encryption chipmaker Hualan has suspicious ties to China’s military. Yet US agencies still use one of its subsidiary’s chips, raising fears of a backdoor.
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.
A new ransomware gang named 'Money Message' has appeared, targeting victims worldwide and demanding million-dollar ransoms not to leak data and release a decryptor.
This is a statement on the NZZ news article from January 9, 2023 about alleged weaknesses in Threema's encryption. But these are completely impractical and theoretical.
Microsoft Office 365 Message Encryption (OME) utilitises Electronic Codebook (ECB) mode of operation. This mode is insecure and leaks information about the structure of the messages sent and can lead to partial or full message disclosure.
The Russia-linked ransomware gang demanded $20 million in ransom — and the overthrow of Costa Rica's elected government. Where does that leave smaller, equally vulnerable nation states?
