A ransomware virus using the .m0on file extension to encrypt files has been reported to cause havoc on user PC’s. The virus is also known as Crypute and uses the Advanced Encryption Standard(AES) algorithm to encrypt videos, pictures, audio files and documents of importance to the computers it infects. At the moment there are several methods by which the .m0on ransomware may spread and users are warned not to open various e-mail attachments as well as perform checks on any URLs they deem suspicious. In case of infection with this ransomware, experts advise victims to focus on removing the ransomware and restoring the files yourself instead of making the ransom payoff.

M0on Ransomware – Further Information
How Does M0on Spread?
To cause an infection, M0on may use two primary types of techniques – via URLs or files. In case the virus uses files to infect users, it is widely believed to take advantage of e-mail spam and use it against the interests of the user. The spammers may send an e-mail pretending to be of utmost importance for the user in order to convince him to open the e-mail attachment which may usually pretend to be an executable concealed behind a fake document.
But this does not mean that URL infections are not also present in phishing mails. We have even had cases where the e-mails have malicious URLs that are modified so that they resemble fake LinkedIn or PayPal buttons, just like an original e-mail.
What Does M0on Ransowmare Do After Infection
After the user has clicked on the malicious URL or downloaded and executed the fake malicious file, infection Is commenced and the malware connects to the remote host of the cyber-criminals and downloads the payload if the malicious executable is not the actual payload which is less likely.
Then, the .m0on file extension ransomware uses a very particular trick up it’s sleeve. It may delete the shadow copies on the infected computer to eliminate any chance of backup on the compromised computer:
Not only this, but the .m0on variant of CryPute can support most of the commonly used file extensions to encrypt user files, for example:
- Video files.
- Files associated with Microsoft Office.
- Adobe files (Reader, Photoshop, Illustrator, Elements, etc.)
- Audio file formats.
- Database files.
- Virtual machine files.

After encryption the files have their names changed to completely randomly written “n”, “m”, “o” and “0” letter in between the “%” symbol sign. The encrypted files also have the .m0on file extension added as a suffix after them, for example:
After encryption, the virus is reported to drop a ransom note to notify the victim of the situation.
