What is Payday ransomware? And how does it implement its attack?

Payday ransomware is a file-encrypting virus that was first discovered at the end of January 2019. This new ransomware threat uses random characters as extension of the files it encrypts. At the time of writing, it isn’t known yet if this new crypto-virus belongs to any ransomware group.
After it infects a computer, it drops its payload file which is the one that connects the infected computer to a remote server controlled by the attackers. It then downloads its malicious components from this server and drops them into system folders in order to launch or repress system processes. It employs a data harvesting module that collects information from the system and sends them to the remote server. Another module called stealth protection is executed which is the one that bypasses security programs installed in the computer. It also makes modifications in the Windows Registry so that it can automatically execute its attack every time the computer is started.
Once the system modifications are completed, Payday ransomware will begin encrypting files using a sophisticated encryption algorithm which is still currently unknown. Following data encryption, it opens a file named “HOW_TO_DECRYPT_MY_FILES.txt” which contains the following content:
“============== !!!PAYDAY RANSOMWARE!!! ==============

to decrypt your files – you must buy decryptor. Decryptor price – 200 USD.
