What is Cylance Ransomware

Cylance is the name of a ransomware infection that targets Windows and Linux users. Users infected with this type of malware will no longer be able to access their data due to encryption. In addition, victims will also see the affected files modified with the .Cylance extension. After this, they will be no longer accessible and victims will have to follow decryption instructions in the generated ransom note (named CYLANCE_README.txt). Please note that Cylance Ransomware has nothing to do with Cylance by BlackBerry – legitimate enterprise cybersecurity solutions.

In general, the ransom note says the victim’s data has been encrypted and cybercriminals are the only holders of private keys that are able to decrypt it. To obtain this key and presumably software for running decryption, victims are instructed to contact the swindlers via e-mail and transfer money to them. The price is undisclosed and most likely calculated for each victim separately. Additionally, cybercriminals also offer to test decryption for free by sending one encrypted file. No matter how trustworthy cybercriminals seem, it is always advised against collaborating with them and paying the ransom. Many victims end up fooled and do not receive promised decryption tools. While this has not been reported to be the case with Cylance Ransomware, the risk exists nonetheless.

Unfortunately, ransomware developers are indeed the only source of getting the key for decryption. Sometimes it is possible to run independent decryption using third-party tools or windows shadow copies, however, this happens only in rare cases when ransomware is flawed or accidentally failed to actually encrypt the data during its operation for whatever reason. At the time of writing this article, no third-party tools are capable of cracking the ciphers generated by Cylance Ransomware. Thus, the only ways to recover your data are either by collaborating with ransomware developers or retrieving data from existing backup copies. Backups are copies of data stored on external devices such as USB drives, external hard drives, or SSDs.

It is always safer to use backups copies instead of paying the attackers. As was mentioned before, paying cybercriminals is always a risk and does not fully guarantee the receiving of promised keys/tools. Therefore, make sure to create regular backups so that your data can be recovered in case of unexpected loss or ransomware infection. If you are going to recover your data without the involvement of cyber-swindlers, it is essential to delete the ransomware virus from your system so that it does not impact other files or spread to neighboring systems. Even if you choose to collaborate with them to decrypt files, it is still important to make sure the ransomware is uninstalled from the system later on.

How Cylance Ransomware infected your computer

Ransomware is known to penetrate unprotected systems in a variety of ways – for example, via phishing e-mail letters, unprotected RDP configuration, infected software installers (pirated or cracked), exploit kits, trojans, fake updates/license cracking tools, unreliable ads, backdoors, keyloggers, and other dubious channels. Most of these channels are aimed to trick inexperienced/naive users into downloading and opening some malicious file or link. One example is fraudulent e-mails that often disguise harmful attachments as legitimate and genuine files, such as .DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS. Such messages tend to mimic templates of trustworthy organizations (e.g., delivery companies, tax authorities, banks, and so forth) to look legitimate and make users do what they need.

Being careful on the internet should be your top priority. As such, avoid interacting with shady download resources, torrent-sharing websites, dubious ads, potentially malicious attachments/links, and other types of content that may seem suspicious or compromised. Download software only from official and trusted resources.
