Rastar Ransomware
Do you see the strange extension .rastar appended to the names of your valuable files? In such an unfortunate event you should know that the ransomware Rastar is running on your PC. It is another malicious software that has been developed with the goal to blackmail people into sponsoring hackers’ operations.
Rastar virus is known to invade computer operating systems without people being able to register any suspicious activities. Typically, ransomware threats obtain access to PCs via malicious attachments, hacked websites, torrent files, freeware installers, and fake system notifications. Once running on a PC, Rastar is able to corrupt essential system settings which will lower system security.
Afterward, the threat will reach target files to transform their code with a specific cipher algorithm. This encryption process will make files completely inaccessible. Corrupted files are those that contain the extension .rastar in their names. According to hackers, their recovery is possible only with their help. However, there is never a guarantee that they will act as they promise.
Check out more details about Rastar ransomware and find out how to remove it completely from the infected PC.

Rastar Ransomware Virus
Rastar is ransomware that once started on a PC will try to bypass active security measures and complete its attack to the end. It is malicious software that has been created to pass through several different stages. This way it compromises essential system settings and encodes personal files to extort a ransom.
Rastar ransomware will apply some changes that will enable it to stay unnoticed on the system as long as possible. Like a typical ransomware, it is likely to affect the Windows Registry. Windows Registry is a hierarchical database that stores low-level settings that support the proper system performance. Malicious values may appear under specific registry keys such as Run and RunOnce in case of infection with the Rastar virus. This move will enable the ransomware to load automatically on every system start. Hence, it will encode newly created files and keep the system vulnerable to additional malware intrusions.
The spread of Rastar ransomware payload files is likely to happen via different mechanisms including spam emails with malicious attachments, hacked websites, URL addresses to these websites, cracks, software keys, and various free programs.
Once the encryption stage is a fact, Rastar ransomware will activate a specially crafted cipher module that will scan system drives for target files and encodes them with a strong encryption algorithm. Corrupted may be all of the following files:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc.
The encryption process enables the ransomware to restrict access to data stored by corrupted files. Inaccessible files will be all files that contain the extension .rastar in their names.
All nasty consequences of an infection with the Rastar virus are misused by hackers. They will try to blackmail you into contacting them and paying them a ransom fee for a decryption tool that will supposedly recover .rastar files. However, they are cybercriminals in the first place. Don’t forget it. They may say many things but no one can ever be sure that they will act as promised.
The nasty message left by Rastar ransomware can be read in a file called HOW_TO_DECYPHER_FILES.txt. This file will appear somewhere on the system at the end of the attack. Here is a copy of its content:
