Kcvp is a ransomware that belongs to the Stop/Djvu Ransomware family. Analysts at SecneurX found that Kcvp encrypts files and appends its extension (".kcvp") to filenames. Also, it drops the "_readme.txt" file that contains a ransom note.
After executing the Kcvp ransomware all files and folders got encrypted and appended their filenames with a ".kcvp" extension. For Example a file titled as "Sep2019.docx" appeared as "Sep2019.docx.kcvp", "Jan2020.docx" as "Jan2020.docx.kcvp", and so on.

How does ransomware infect my computer?
Malware (ransomware included) is spread using phishing and social engineering tactics. Malicious programs are typically presented as or bundled with ordinary content. Infectious files can be executables (.exe, .run, etc.), archives (ZIP, RAR, etc.), Microsoft Office and PDF documents, JavaScript, and so on. When a virulent file is executed, run, or otherwise opened - the infection process is jumpstarted.

What can you do to avoid being a ransomware victim?
As dangerous as ransomware is, simply being aware and staying updated with the latest ransomware trends can go a long way in securing your data and systems. Here are helpful tips on how you can defend yourself from a likely attack.
Scrutinize emails & its attachments before opening them
Be wary of emails from unverified sources. You can check by communicating directly with the purported sender to confirm if they sent the messages. To check its validity, you can use SecneurX Sandbox to verify the sanity of the email
Avoid clicking embedded links found in unverified emails
Such social engineering tricks can lead to the download of ransomware. Additionally, be wary of sites that prompt you to enter a CAPTCHA code as this could be linked to a ransomware attack. To check its validity, you can use services like SecneurX Sandbox to verify the reputation of the site.
Back up your important files
While prevention is always better than the cure, having a backup of important files can at least lessen the potential damage done by a ransomware attack. While being locked out of your own system is always a bad thing, at least it's not a total disaster since you can always retrieve your important files. The 3-2-1 backup rule applies here—three backup copies of your data on two different media, and one of those copies in a separate location.
