What is Ad Virus ransomware? And how does it execute its attack?
Ad Virus ransomware is a file encrypting malware designed to encrypt important data in a computer. It also happens to be a new variant of the notorious GlobeImposter ransomware. This new variant still follows the same sequence of attacks as with other GlobeImposter variants but this time around it uses the .ad extension in marking its encrypted files.
The instant it execute its attack, it may drop a seemingly legitimate executable file which is actually the malicious payload of Ad Virus ransomware. It then 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 Ad Virus 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.
Ad Virus ransomware makes use of a strong encryption algorithm in locking its targeted data and adds the .ad extension after it completes the encryption. After it encrypts files, the crypto-virus creates a file named “Read_For_Restore_File.html” which contains the following content:
“YOUR FILES ARE ENCRYPTED!
Your documents, photos, databases and all the rest files encrypted cryptographically strong algoritm RSA-2048.
Without a secret key stored with us, the restoration of your files is impossible
