.ROLDAT Ransomware - Remove It and Decrypt Files

by Martin Beltov | May 2, 2019 | 0 Comments .ROLDAT, Decrypt Files, ransomware, removal guide, STOP Ransomware, Update June 2019

The .ROLDAT ransomware is a new variant of the STOP/DJVU family. It is very probable that it is made by an inexperienced hacking group as it is based on the base code of the main virus threat. Such customization options are widely available on the underground markets and communities. These samples can be spread using the most common distribution methods.

One of the most popular methods is to coordinate email phishing messages that pose as notifications that have been sent in by services. The attachments and built-in content will lead to the ransomware infection. A similar technique is the creation of malware sites that have been made by the hackers and pose as legitimate and safe destinations: portals, download pages or even search engines. They are hosted on similar sounding domain names and even self-signed or stolen certificates.

Most of the virus threats of the STOP ransomware family can also be caused by interaction with dangerous payload carriers such as setup files of popular end-user software such as system utilities, creativity suites and etc. Likewise in a similar manner the dangerous scripts can be integrated into the most famous file formats: presentations, spreadsheets, text files and databases. When opened by the victims a pop-up message will be presented asking the users to enable the built-in macros which will trigger the .ROLDAT ransomware infection. A popular alternative is the upload of malware browser plugins which are also known as hijackers. They are frequently uploaded to the relevant repositories with fake descriptions, fake reviews and developer credentials.

Usually these infections begin with an advanced information gathering module which will extract certain strings. They can reveal the identity of the victim users which can be used for conducting various crimes including financial abuse and identity theft. The engine can also retrieve machine metrics which can be fed to a special algorithm which will create an unique ID for each affected machine.

The collected information can be used by another module called security bypass which will allow the virus engine to disable the software which can block the proper ransomware behavior pattern. The list of apps that are commonly targeted include anti-virus programs, sandbox environments, firewalls and virtual machine hosts.

As soon as this is done all kinds of system changes can occur. This includes the setting up of the threat as a persistent threat which means that it will start every time the computer is booted. A related mechanism is modification of entries found within the Windows Registry. It can create new strings for itself and modify already existing ones — this can lead to serious performance issues and data loss. The made infections with the .ROLDAT ransomware may also be used to install other viruses — Trojans, miners and hijackers.

When all changes have been committed the actual ransomware operations will take place. Using a strong cipher target user data will be processed. Like previous STOP family samples a built-in list of target file type extensions may be used: documents, archives, backups, music, videos, images and etc. In the end the .ROLDAT extension will be applied to them. An associated ransomware note will be created in order to coerce the victims into paying the hackers a decryption fee.
