The .sepsys virus is a ransomware that is currently set against target end users on a global scale. There is no information available about the hacking group behind it. It is believed to be a new iteration of the famous ransomware family. This is one of the reasons why we believe that the hackers are experienced.
Once the .sepsys virus has started it will execute its built-in sequence of dangerous commands. Depending on local conditions or the specific hacker instructions various actions will take place. The file encryption will begin after them — the encrypting component will use a built-in list of target file type extensions. In the end the victim files will be renamed with the .sepsys extension.

The .sepsys virus which is alternatively known as as the SepSys Ransomware is a new malware threat that is currently set against computer victims. There is no information regarding the hacking group available and this also means that there is no data gathered about te preferred distribution method. It is very possible that the most popular ones are going to be used. Some of them include the following:
- Phishing Campaigns — The criminals can organize large-scale phishing campaigns which are set to manipulate the victims into believing that they are interacting with a legitimate notification or message. The two most common forms are email messages and hacker-controlled sites. They can be hosted on domain names that sound very similar to the ones which are impersonated. Self-signed security certificates can be uploaded.
- Malware Files — The virus code can be inserted in macro-infected documents or setup bundles — they can be of popular programs which are commonly downloaded by end users.
- Files Distribution — These files can be spread over to file-sharing networks such as BitTorrent and even various social networks, chat rooms, forums and etc.
As soon as the .sepsys virus is installed on a given computer an extensive list of components and modules will be run. The security analysis shows that one of the advanced functionality which is included in the virus code is the ability to start, stop and interact with system device drivers, including the ability to install the malware code through them — this will bypass most of the security systems and applications which are installed on the host computer.
The .sepsys virus running process will be allocated to a reserved memory space — this will make it much harder to stop the running processes. This is also used to guard the ransomware from debug environments and virtual mchine hosts execution.
The virus also contains an advanced information gathering module which has been found to acquire data in two categories:
- Machine Information — This can generate a full report of the installed hardware parts and certain system environment values.
- Personal Information — It is very possible that this engine can be used to acquire information that can reveal the identity of the users.
The .sepsys virus may also interact with the system using the operating system services — this will allow the main engine to execute various changes including the ability to set itself as a persistent threat — it will start automatically when the computer is powered on.
The main infection engine can also interact with the system mount manager — it can access available network shares and removable devices which will be infected by the .sepsys virus. Any modifications to key system configuration files and the Windows Registry may lead to severe performance issues, data loss and unexpected errors.
The .sepsys virus is a ransomware which will use the typical approach of using a built-in list of target file types — they will include frequently accessed data: archives, backups, databases, multimedia files and etc. The processed files will be renamed with the appropriate .sepsys extension and a ransom note will be created in a file called README.html.
