Why is Noos dangerous?

After Noos applies the encryption, it leaves you a ransom note. You can find it on your Desktop, and in every folder that contains locked date. It’s called “_readme.txt,” and it’s pretty standard in terms of contents. The note explains your situation, and offers you a solution. Tat solution being to comply. Supposedly, if you pay the ransom, you’ll get the key you need. Apply it, and your files are free. But here’s the thing. These are the words of cyber criminals. People, who take your data hostage and seek to exploit your fear and naivety for monetary gain. You can’t trust the promises they make. These are individuals, who will double-cross you. And, even if they don’t, you’re still not in the clear. Let’s examine your options, shall we? Say, you choose to pay. You send the requested sum, and you await to get the key. What if you don’t get it, though? What if these people don’t send it your way? Or, what if they do, but it proves useless? What’s more, even if you do get the right key and it works, don’t rejoice yet. Think about it. You pay for the key that removes the encryption, not the encryptor. That means, even if you unlock your data, Noos remains on your PC. And, it’s free to strike again, and lock your files once more. It can run its encryption algorithms a mere minute after you decrypt the data. Then, what? You’re back to square one. Only this time, you have less money. Don’t put yourself in that position. Don’t play the infection’s game. It’s rigged against you, and you’ll lose every time.
