What is SSHBOT?
Discovered by Karsten Hahn, SSHBOT (also known as P4YME) is a screenlocker - malware that locks computers. The main purpose of SSHBOT is to ensure that victims are unable to access the Windows desktop or use installed programs, files, etc., unless they pay a ransom to the cyber criminals responsible.
The pop-up window (ransom message) displayed by SSHBOT states that the computer is locked and can only be unlocked with a password costing the equivalent of €75. It is stated that victims have 30 minutes to contact the cyber criminals behind this screenlocker via a Telegram account (@perry44) and purchase the password.
After this time, the Windows Operating System will be deleted. You are advised not to contact SSHBOT's developers and, more importantly, not to pay any ransom. Cyber criminals commonly cease cooperating as soon as they are paid.
In summary, victims who trust them and pay the ransom are scammed - they do not receive any tools (passwords in cases such as this) that will supposedly help them to restore access to operating systems, files, etc. The SSHBOT screenlocker can be uninstalled by following the steps described below.
Note that another way to avoid data loss caused by malware is to restore files from a backup.

More examples of other malware similar to SSHBOT and designed to lock screens are ComputerDestroyer, Rubly and StalinLocker. Usually, software of this type is used to extort money from victims. Note that, in most cases, screenlockers do not use encryption algorithms, as is the case with ransomware (screenlockers function as non-encrypting malware).
How did screenlocker infect my computer?
SSHBOT is likely to be distributed through malspam campaigns, Trojans, fake software updaters, untrusted software, file download channels and unofficial software activation ('cracking') tools. Using malspam campaigns to proliferate malware, criminals send emails that contain malicious attachments or website links.
They are malicious programs that can cause chain infections by installing other programs of this kind. Fake software updaters infect computers by installing malicious programs rather than fixes/updates for installed software, or by exploiting bugs or flaws of installed and outdated software.
Free file hosting and freeware download websites, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial pages, third party downloaders, etc., are examples of dubious file/software download sources. They are often used to distribute malware, which is installed when users download and open malicious files promoted through them.
Unofficial activation ('cracking') tools are illegal programs that supposedly activate licensed software free of charge (bypass activation), however, these tools simply install malware instead.

How to protect yourself from malware infections
Software and files should never be downloaded from unofficial pages or through other channels such as third party downloaders, Peer-to-Peer networks (e.g., torrent clients, eMule), and freeware download pages. Third party installers should not be used to install software.
The safest way to download files and programs is to use official websites and direct links. Attachments and website links in irrelevant emails should not be opened, especially if the emails are sent from unknown, suspicious addresses. Installed software must be updated and activated with tools and functions that are provided by official developers.
Third party activation and updating tools often install malware. Furthermore, it is illegal to use unofficial tools to activate any licensed programs. Additionally, operating systems should be regularly scanned for threats with reputable antivirus or anti-spyware software.
Installed security suites should be kept up to date. If your computer is already infected with SSHBOT, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this ransomware.
