 Chemistry is a part of our everyday lives, including our skincare routines. Many popular skincare products contain scientifically studied ingredients that can help improve the appearance and feel of our skin. Here are four common skincare ingredients and what they can do. 1. Niacinamide What is Niacinamide? Niacinamide is a form of vitamin B3 and is one of the most versatile ingredients commonly found in skincare products. What can it do? Niacinamide may help: Support the skin barrier Reduce excessive oiliness Make the appearance of pores less noticeable Calm the appearance of redness Gradually improve uneven skin tone Support clearer-looking skin How much do you need? You don't necessarily need a high concentration to see benefits. For many people, products containing around 2–5% niacinamide can be sufficient. Higher concentrations aren't automatically better and may cause irritation for some people, particularly those with sensitive skin. 2. Vitamin C What is Vitamin C? Vi...

Prometheus ransomware Decryptor for free

Taiwanese security company CyCraft has released a free app that can help Prometheus ransomware victims recover and decrypt their files.


The decryption works effectively by forcing the encryption key used to lock the victim's data, and it is available for free on GitHub.


"As known Prometheus uses Salsa20 ransomware with a random hash count-based password to encrypt Fireworks. The size of the random password is 32 bytes, and each character is a visible character. Since the password uses the tickcount number as the key, we can brutally guess it,” CyCraft Team wrote in a blog post at the beginning of the month.


The only downside to CyCraft decryption is that it can only handle brute force pressing of the decryption key from small files only.


The decryption was released on July 13, and this was also the last date that the Prometheus gang posted any content on the dark web leak site. After two and a half weeks, the Prometheus gang appears to be out of action.


The gang was first spotted in February of this year, and had previously listed more than 40 victims on its leak site. She drew some attention to herself by claiming an association with the more notorious REvil gang, which they removed after the REvil gang's attack on Kaseya.


In fact, on the other hand, the two ransomware strains couldn't be more different. REvil was an advanced piece of C++ malware, while Prometheus was based on the leaked code of Thanos ransomware, encoded in C#.

Soon after Prometheus fell silent, a new group called Aaron, also operating at the head of Thanos' code base, began the attacks, leading some experts to believe that Prometheus' operators renamed them Aaron.


Emsisoft did not rule out that the company will eventually create a decryption tool for Prometheus and other Thanos strains that can also recover large files. If they do, the application will be made available on the company's website and NoMoreRansom portal for free.


Since Thanos-based ransomware strains are causing new victims on a weekly basis, this could be sooner rather than later.
