.amnesia Files Virus – Methods of Distribution
The infection file that triggers .amnesia files virus could be spread with the help of various techniques. Some of the most common are email spam messages, malicious email attachments, malicious URLs, infected software setups and fake updates.
In order to trick you into infecting yourself with the ransomware hackers could send you an email with spoofed email address and sender name. So you should act wisely even when you receive emails that pose as representatives of well-known companies or institutions. Especially if the emails incorporate file attachments described as important documents that need to be reviewed as soon as possible. In case that you make the mistake to open the malicious file you automatically grant access to .amnesia ransomware to your system.

.amnesia Files Virus – Impact
At first, .amnesia crypto virus needs to establish all infection files on the system. For the purpose it could spawn a lot of processes, create several malicious files and modify system settings.
There are several essential system folders that are often used by ransomware to store their malicious files. The .amnesia crypto virus is not an exception and as the analyses of its samples reveal it creates and drops malicious files on the following folders:
- %AppData%
- %Roaming%
- %Temp%
- %Common%
- %{User’s Profile}%
However, the files associated with the infection are not that easy to identify as it could use the names of legitimate system files and processes. That’s why it is recommendable to use the help of an advanced anti-malware tool during the removal process. Such a program could easily analyze the code of all files stored on the system and detect the ones that have some malicious traits.
Before the encryption process, this new iteration of Scarab ransomware enters the Registry Editor to modify auto-execute functionalities and this way ensure its persistent presence on the infected host. By creating malicious values under some specific registry sub-keys, .amnesia ransomware is able to run its malicious files on each Windows start. Targeted registry keys are usually Run and RunOnce as they manage the automatic execution of all essential processes needed for the regular system load.
The final stage of .amnesia infection is reached when a specific ransom message associated with the ransomware appears on the PC screen. The message could be dropped on the desktop in a file named HOW TO RECOVER ENCRYPTED FILES.TXT. It informs the following:
