Ghsd Ransomware (Virus Removal Steps)

Cyber criminals developed ransomware Ghsd as a means in materializing their extortion activities. This threat is one of the many coder crypto-viruses that currently roam the internet and may arrive on the computer in various schemes. Online users can get their hands on this ransomware by viewing distrusted web sites and downloading software from it. Imprudent email users are also prone to Ghsd ransomware infection, especially if security measures are disregarded when accessing the incorporated file. As computer security experts always remind us, scanning the attached file before opening is a way to avoid any type of virus and malware infection.

More about the Ghsd virus

The moment that Ghsd virus runs on the computer, it initiates a connection to the remote computer server to receive specific orders. If the infection is due to Trojan Downloader, the task is to retrieve the ransomware module from the remote server, which is under hacker’s control. Once the virus becomes a fully functional ransomware, it obtains the public key from the server and starts the encryption process using an advanced technique. Ghsd will apply the public key to encrypt the target files. That said, each computer is affected with a unique key and thus, the private key for file recovery is not possible to unlock data from another device infected by Ghsd ransomware.

In addition to applying sophisticated encryption, the virus will run a file modification process to append the data with additional extension strings containing the unique identifier. The specific .ghsd file extension is inserted to file format. As a result, the usual photo.jpg will be a new and unfamiliar data as photo.jpg.ghsd. Assuming that merely renaming the file to its original format will make it useful again is an erroneous assumption by the victims of most ransomware. As mentioned, the file was encrypted by jamming the first certain quantity of bytes.
