Mr403Forbidden Ransomware

It is unknown yet if Mr403Forbidden Ransomware will spread in the future, but, at this point in time, it does not appear to slither into unguarded operating systems and encrypt the files found on them. This is not surprising, considering that Ransed Ransomware, BrainLag Ransomware, and many other infections have been found to be just as helpless. The volume of ransomware infections nowadays is mind-blowing, and so it is natural that many of them are created by people who do not know the first thing about malware.

It is most likely that the C&C server that Mr403Forbidden Ransomware communicates with is down, and that is why this threat is not fully active. Of course, that can change at any moment. There are plenty of things that are very unpredictable when it comes to this infection, and the distribution is one of them. Since the threat is not actively spreading, it is hard to say how Windows users would attract it. Of course, the operating system has to be unguarded; otherwise, the infection’s launcher would be removed before anything malicious was initiated. If the operating system is not guarded, various security backdoors can be used to infiltrate this threat. According to our research, spam emails are utilized by most threats of this kind, and malicious installers are attached to them to trick users into executing them without realizing the danger. Once the ransomware is executed, the encryption should start not long after that. According to our analysis, the files encrypted by the threat should get the “.alosia” extension appended to their names. Unfortunately, we could not figure out if the infection was also capable of renaming files, which some ransomware threats can do.

Upon execution, Mr403Forbidden Ransomware should open a window entitled “File Anda Terkunci!!!,” which translates to “your file is locked” from Indonesian. The message within the window, however, is presented in English, and it informs that there is only one way to decrypt the files, and that is by paying a ransom. There is no information regarding the payment, which is why the two email addresses ( and are added. Allegedly, if you email the creator of Mr403Forbidden Ransomware, you will get a code that will initiate the decryption of your files. First, of course, you would have to pay money to get this code. Is the decryption code real? Will it be provided to you after the payment of the ransom? Taking into account that the victims of ransomware infections are usually left empty-handed, it is safe to say, that the code will not be given to you, and that is why we do not recommend paying the ransom.

Although the information about Mr403Forbidden Ransomware is limited at the time of our research, the removal of this malicious infection is unlikely to be extremely complicated.
