What is SSHBOT?

SSHBOT (also known as P4YME) is the name of a screenlocker - a piece of malware designed to lock a computer. The main purpose of SSHBOT is to ensure that victims could not access the Windows desktop or use installed programs, files, etc., unless they pay a ransom to cyber criminals behind it. This malware was discovered by Karsten Hahn.

As explained in a pop-up window (ransom note) displayed by SSHBOT, a computer is locked and can be unlocked with a password which costs €75. It is stated that victims have 30 minutes to contact cyber criminals behind this screenlocker via Telegram (the @perry44) account and purchase the password, after that the Windows operating system will be deleted. It is advised not to contact SSHBOT's developers and more importantly, not to pay them a ransom. It is common that cyber criminals stop cooperating as soon as they get paid. Simply said, victims who trust them (pay a ransom) get scammed - they do not receive any tools (passwords in cases like this one) that supposed to help them to restore access to operating system, files, etc. The SSHBOT screenlocker can be uninstalled by following steps described below. It is worthwhile to mention that another way to avoid data loss caused by malware is to restore files from a backup.

More examples of other malware that is designed to lock screen like SSHBOT are ComputerDestroyer, Rubly and StalinLocker. Usually software of this type is used with a purpose to extort money from its victims. It is worthwhile to mention that in most cases screenlockers do not use any encryption algorithms like ransomware does (they function as non-encrypting malware).

How did screenlocker infect my computer?

It is very likely that SSHBOT is distributed through malspam campaigns, Trojans, fake software updaters, untrustworthy software, file download channels or unofficial software activation ('cracking') tools. When cyber criminals malspam campaigns with a purpose to proliferate malware, they send emails that contain malicious attachments or website links. Typically, they attach some malicious Microsoft Office document, archive file like ZIP, RAR, PDF document, executable file like exe., or JavaScript file and wait until recipients will open, execute it. After being executed such files install malware. Trojans can cause damage only when they are already installed on the operating system. They are malicious programs that can be designed to cause chain infections - install other programs of this kind. Fake software updaters infect computers either by installing malicious software instead of fixes, updates for installed one, or by exploiting bugs, 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 unreliable file, software download sources. It is because quite often they are used to distribute malware. It gets installed when users download and open malicious files through them. Unofficial activation ('cracking') tools are illegal programs that supposed to activate licensed software for free (bypass its activation). Although, it is common that such tools install malware instead.

How to protect yourself from malware infections?

Software and files should never be downloaded from unofficial pages or through other channels like third party downloaders, Peer-to-Peer networks (e.g., torrent clients, eMule), freeware download pages. Third party installers should not be used to install any software too. 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 such emails are sent from unknown, suspicious addresses.  Installed software must be updated and/or activated with tools and/or functions that are provided by its official developers. Both third party activation and updating tools often are designed to install malware. Also, it is not legal to use unofficial tools to activate any licensed programs. Additionally, operating system should be regularly scanned for threats with a reputable antivirus or anti-spyware software. Installed security suite should  always be up to date. If your computer is already infected with SSHBOT, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.
