Cryptotes ransomware removal instructions
What is Cryptotes?
Discovered by Michael Gillespie, Cryptotes is a malicious, ransomware-type program and a new variant of RotorRansomware. Cyber criminals use computer infections of this type to encrypt data stored on victims' computers and to extract money from affected people by making ransom demands. Cryptotes is designed to add a new extension (".cryptotes") to each encrypted file, which also includes an email address. For example, "1.jpg" becomes "firstname.lastname@example.org". It also creates a "readme.txt" file.
Generally, the text files are ransom messages that contain information on how to decrypt the data, email addresses for contacting the ransomware developers, and so on. In this case, however, it contains just a few lines of text stating "ROTO Readme". It is very unlikely that these cyber criminals can be contacted via the email@example.com email address, which is included in the extension added to each encrypted file. Notably, this is a Yahoo email address, indicating that Cryptotes's developers are probably not professional ransomware developers - cyber criminals who use legitimate, publicly accessible email service providers such as Yahoo can be tracked by authorities. In any case, we do not recommend that you contact any ransomware developers, including developer of Cryptotes. Most cyber criminals demand ransom payments (in effect to purchase decryption tools). Once they receive the money, however, they ignore the victims. Therefore, most people are scammed. Unfortunately, most ransomware developers employ cryptography algorithms (symmetric or asymmetric) that make these encryptions 'uncrackable'. Therefore, encrypted files can be decrypted using a specific decryption tool. Only the developers of the ransomware can provide this tool. This allows them to blackmail victims who believe they have not option other than to pay the ransom. The best option in these cases is to use an existing backup and restore files from there.

All ransomware-type infections are very similar. Examples of the many other malicious programs similar to Cryptotes include Maoloa, .blower, and CryptoID. These programs encrypt data and allow their developers to blackmail users who have computers infected by their ransomware. Main differences are usually size of ransom (cost of a decryption tool) and cryptography algorithm used to encrypt files. Unfortunately, most encryptions cannot be decrypted without the involvement of ransomware developers, unless the program contains flaws/bugs or is not fully developed. We recommend that you maintain data backups and keep them stored on remote server or unplugged storage device. Otherwise, backups are encrypted together with other data stored on the computer.
How did ransomware infect my computer?
It is difficult to determine exactly how Cryptotes's developers proliferate this malware (malicious program), but they often use spam (email) campaigns, fake software updaters, Trojans, untrustworthy software download sources, or software cracking tools. When using spam campaigns, cyber criminals send emails that include malicious attachments such as MS Office documents, archive files (ZIP, RAR), PDF files, executable files (.exe), and so on. The main purpose of these emails is to trick people into opening these attachments. Generally, sent emails are presented as important and legitimate. Once the attachment is opened, it downloads and installs a malicious program. Fake software updaters usually infect systems by downloading and installing computer infections rather than the promised/expected updates, or fixes. Alternatively, they cause infections by exploiting bugs/flaws of outdated software. Trojans are malicious programs that cause chain infections. If a is Trojan installed, it is likely that it will install ransomware or some other computer infection. Third party software download sources such as freeware download websites, free file hosting websites, peer-to-peer (P2P) networks (such as eMule, torrent clients), and so on, often are used by cyber criminals who present malicious files (usually executables) as legitimate. People who download and execute them cause infections on their systems. Software cracking tools supposedly bypass software or operating system activation free of charge, however, many cyber criminals employ these tools to proliferate malicious programs such as ransomware.
How to protect yourself from ransomware infections?
Avoid opening email attachments or web links in emails received from unknown, suspicious addresses. If you believe that the received email is irrelevant (or contains an attachment or web link), simply ignore it and do not open included links or files. Download software using official, trustworthy sources and directs links only. Do not use any third party channels, since they could be used to proliferate unwanted applications and computer infections. Keep installed software updated, however, this should be done using tools or functions that are provided by official software developers only. Avoid software cracking tools, since using them is committing a cyber crime. Furthermore, they often infect computers rather than allowing use of software free of charge. Finally, have reputable anti-virus or anti-spyware software installed. These tools protect computers from various infections. If your computer is already infected with Cryptotes, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Cryptotes are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
