What is MOSN Ransomware
MOSN is categorized as a ransomware infection that demands money from victims after encrypting data. Normally, such infections strike all potentially important files like photos, videos, documents, databases, and more that comprise some value to victims. The encryption can be spotted by new extensions that are assigned to each compromised piece. For instance, a file named
1.pdf will change to
1.pdf.MOSN at the end of encryption. The same will be seen with other data according to this pattern. Then, soon after this, MOSN installs new wallpapers stretched out across the entire screen that displays a short ransom summary. It states victims should contact developers via email@example.com e-mail address and pay 300$ in Bitcoin for data redemption. Additionally, MOSN Ransomware creates a text file called INFORMATION_READ_ME.txt that explains the same but also mentions the number of encrypted files and unique ID that should be attached whilst contacting extortionists.

CONTACT FOR DECRYPTION
Unfortunately, in most ransomware scenarios, decrypting data without cybercriminals appear to be almost an impossible task. This is because developers are the only figures knowing how to approach the encrypted data correctly. Using third-party instruments may be a good, but still risky idea as it can damage your files forever. This is why the only and best way to avoid paying the ransom is deleting ransomware and recovering files via backup copies. If there is no such option available in your case, you can still give it a try via special decryption and recovery tools developed by third-party vendors. All possible solutions, as well as removal instructions, are presented below.
How MOSN Ransomware infected your computer
File-encryptors and other malware can be spread via hacked RDP configuration, e-mail spam letters, backdoors, trojans, keyloggers, fake updates or antimalware software, and other kinds of suspicious channels. Most notably, ransomware infections have been distributed via so-called spam, bombarded by e-mail. Cybercriminals learned this is hyper-effective and started sending a bunch of identical letters that store malicious attachments. Usually, inexperienced users are less likely to distinguish whether something malicious is present. Fraudulent figures make everything sure that no inexperienced user spots something suspicious. They disguise their messages as something “legitimate” or “urgent”, falsify e-mail addresses with genuine-looking names, and tell users to open the files or links. Such files are usually PDF, EXE, DOCX, XLSX, ZIP, RAR, or JS formats bundled inside of a message. Once opened, they are likely to install malicious software like MOSN Ransomware. Note that these file formats have nothing in common with malware initially, however, some frauds are educated enough to adjust them for containing infections. If you are looking for complete malware protection to combat such threats in the future, follow our guidelines below. There is a lot of useful information dedicated to it.
