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 or the loss of important data. In this paper, we analyzed Hive ransomware, which appeared in June 2021. Hive ransomware has caused immense harm, leading the FBI to issue an alert about it. To minimize the damage caused by Hive Ransomware and to help victims recover their files, we analyzed Hive Ransomware and studied recovery methods. By analyzing the encryption process of Hive ransomware, we confirmed that vulnerabilities exist by using their own encryption algorithm. We have recovered the master key for generating the file encryption key partially, to enable the decryption of data encrypted by Hive ransomware. We recovered 95% of the master key without the attacker’s RSA private key and decrypted the actual infected data. To the best of our knowledge, this is the first successful attempt at decrypting Hive ransomware. It is expected that our method can be used to reduce the damage caused by Hive ransomware…

President Biden joined European leaders this week in enacting economic sanctions against Russia in response its military invasion of Ukraine. The West has promised tougher sanctions are coming, but experts warn these will almost certainly trigger a Russian retaliation against America and its allies, which could escalate into cyber attacks on Western financial institutions and energy infrastructure.

A good lesson in reading the fine print:
Cignpost Diagnostics, which trades as ExpressTest and offers £35 tests for holidaymakers, said it holds the right to analyse samples from seals to “learn more about human health” — and sell inf…

The story is an old one, but the tech gives it a bunch of new twists:

Gemma Brett, a 27-year-old designer from west London, had only been working at Madbird for two weeks when she spotted something strange. Curious about what her commute would be like when the pandemic was over, she searched for the company’s office address. The result looked nothing like the videos on Madbird’s website of a sleek workspace buzzing with creative-types. Instead, Google Street View showed an upmarket block of flats in London’s Kensington.

[…]

Using online reverse image searches they dug deeper. They found that almost all the work Madbird claimed as its own had been stolen from elsewhere on the internet — and that some of the colleagues they’d been messaging online didn’t exist…

A Berlin-based company has developed an AirTag clone that bypasses Apple’s anti-stalker security systems. Source code for these AirTag clones is available online.

So now we have several problems with the system. Apple’s anti-stalker security only works with iPhones. (Apple wrote an Android app that can detect AirTags, but how many people are going to download it?) And now non-AirTags can piggyback on Apple’s system without triggering the alarms.

Apple didn’t think this through nearly as well as it claims to have. I think the general problem is one that I have …
