Pysa Ransomware marks files that it locks (with a robust encryption algorithm) with .pysa extension and drops ransom notes called Readme.README in every folder that has locked data. Our specialists say that the information on its ransom note suggests that its creators might be not after regular users, but after organizations or businesses. Such malicious applications are often used for money extortion. Since this threat might be after companies, its developers may ask for more significant amounts of money. Thus, we recommend not to make any rash decisions and consider whatever the threat’s creators may propose carefully. Also, we encourage those who encounter it to read the rest of our article to learn more about Pysa Ransomware. Users who have questions about the malware could also use our comments section available at the end of this page.
Victims of threats like Pysa Ransomware often launch them without realizing it. That is because the installers of such malicious applications can look like text documents or legit setup files. Not to mention, such data can be spread through various file-sharing websites, pop-ups, and so on. Plus, it can be delivered to targeted victims via email. In such a case, all that is left for a victim to do is open the malicious attachment without checking it with a reliable antimalware tool first. Scanning files is highly advisable when you do not know why a file was sent to you, who sent it to you, or if it comes from an unreliable source like a torrent website, and so on. Such a process should not take lots of time and, most importantly, at the end of it, you should know if it is safe to open scanned data or not. If it is not, a legit antimalware tool ought to help you get rid of it.
If Pysa Ransomware slips in, it should start encrypting documents and other valuable files. Our specialists believe that the malware might not encrypt only the data associated with Windows or other software installed on an infected device. Victims can easily recognize encrypted files from .pysa extension that should appear at the end of their title, e.g., document.pdf.pysa. Once the encryption process is over, the malicious application should drop files called Readme.README. All of them ought to contain the same ransom note saying: “Hi Company, Every byte on any types of your devices was encrypted. Don't try to use backups because it were encrypted too.” It is possible that Pysa Ransomware could encrypt backup data located on an infected computer. However, if your backup is located on a removable media device that was not attached when your system got infected or cloud storage, your backup copies might be safe.
We cannot be one hundred percent sure that Pysa Ransomware’s creators will demand payment in exchange for decryption tools as we have not tried to contact them. Still, as said earlier, hackers behind such threats usually create them for money extortion, so it is quite possible. Since paying a ransom is always risky, we advise against it.
Whatever you decide, you should make sure that the malware gets erased. The threat may delete itself after encrypting your files, but just to be sure, you could complete the steps provided below or scan your computer with a reliable antimalware tool.
