What is Xxxxx ransomware? And how does it carry out its attack?
Xxxxx ransomware is a file-encrypting malware created to lock important data in a targeted machine. This is a new variant of 0x4444 ransomware which belongs to the GlobeImposter ransomware group and uses a string of “.xxxxx” in marking the files it encrypts. There are no major changes in this new variant except for the extension it uses as well as its ransom note, other than that, it still follows the same pattern as its predecessor.
Once Xxxxx ransomware carries out its attack, it will drop a seemingly legitimate executable file named “svhost.exe” which is actually the malicious payload of Xxxxx ransomware. After that, it connects the infected computer to a remote server controlled by the attackers. In this remote server, it downloads other malicious components and places them on system folders. These malicious components are then used to make alterations in the Windows Registry so that Xxxxx ransomware can run on every system boot. Once these changes are applied, the search for files to encrypt began. It usually targets common user-generated files such as documents, images, videos, audio, database, archives, and many more.
Xxxxx ransomware makes use of a strong encryption algorithm in locking its targeted data and adds the .xxxxx extension after it completes the encryption. Following data encryption, the crypto-virus creates an HTML file named “how_to_back_files.html” which contains the following content:
“YOUR PERSONAL ID
