What is Relock ransomware? And how does it carry out its attack?

Relock ransomware is a new data-encrypting malware created to encrypt important files in a computer. It adds an extension that consists of a group of numbers to every file it encrypts. This was first spotted in early August 2019 and locks data using the XOR cryptography.

Once Relock ransomware is activated on a targeted system, it adds more malicious files to help it execute its attack – some of which are created by the ransomware itself while others are downloaded from its Command and Control server. After it successfully drops these files in the essential Windows system folders, it might also create and alter some Registry entries so it can run on every system startup. Following the modifications in the registry, Relock ransomware will scan the entire computer drive to look for files to encrypt. It most likely targets common user-generated files like documents, images, database, videos, audio files, and so on. As mentioned, it uses the XOR encryption algorithm in locking files and after it locks these files, it appends random numbers to each one of them and releases two ransom notes namely, FIX_Instructions.txt and FIX_Instructions.hta, which contains the following message:
