.ROGER Virus File (Dharma Ransomware) Update April 2020
A recent sample of the .ROGER ransomware has been captured in a live attack campaign. It gives further information about the current infections. The hacking group which is behind this iteration. According to the available information the majority of malicious files are executables. There are several main methods which are used to spread them. They can include phishing strategies that manipulate the victims into opening up the files. This includes the preparation of email messages and hacker-controlled sites. .ROGER virus infections can also be caused by interacting with virus-infected files: they can be documents, app installers, patches or updates.
When the infection is started the main engine will start its built-in sequence of malware tasks. The made analysis of a recent sample indicates that this will include a files removal module. It is programmed to delete system data, backups and other related files. This will make it very difficult to restore the infected machines. Victims can attempt to do this by using a data recovery software.
The next step in the infection process is to start a security bypass function which is programmed to probe the system if there are any installed security systems. Usually this includes anti-virus programs, firewalls, intrusion detection systems and etc. They will be stopped or completely removed from the system.
January 2020 saw a new version of the .ROGER virus release which is different from previous iterations by having a different ransom note and contact email. As it is made part of the name of the affected files, this is labeled as a new release of the malware.
As a matter of fact, Italian users should be warned that a new spam campaign seen in February 2020 is targeting the country, carrying the .roger version of Dharma ransomware. The ransom note in this campaign includes the sjen6293@gmail.com email address provided to victims to contact ransomware operators for payment information. The spam email itself contains the following text in Italian:
Gentile cliente,
in allegato alla presente Le trasmetto la nostra fattura.
Si precisa che questa modalita d’invio, tramite posta elettronica,
sostituisce la spedizione catacea e che i documenti allegati
costituiranno l’orginale della fattura
Decreto
Si prega dare gentile conferma di lettura
The translation in English reads the following:
Dear Customer,
attached to this I send you our invoice.
It should be noted that this method of sending, by e-mail,
it replaces the forwarding and the attached documents
will constitute the original of the invoice
Decree
Please kindly confirm reading
The spam email includes a link to an alleged invoice. If the potential victim is tricked into clicking, it will take him to an OneDrive page which hosts a file named ‘New documento 2.zip’. The file is downloaded automatically upon visiting the page.
Previously seen releases add two other email addresses used by the criminals — wang.chang888@tutanota.com or wangteam888@tutanota.com. At the moment there is no information available whether or not these criminals are the same as the previous ones. The mechanism that denotes which contact email is also not known. There are several possible theories:
- Certain Hardware Parameters — The assigned email addresses will depend on the unique ID which is generated during the infection.
- Sequenced Operations — The renaming of the files can be according to a sequenced algorithm.
The .ROGER virus is a dangerous ransomware strain which is descendant from the Dharma malware family. It is being made by an unknown hacking group, most likely it is a reconfigured variant of a previous infection.
It is very likely that it is distributed using the most common techniques. Dharma ransomware are commonly being spread via social engineering techniques which are usually email messages or hacker-made sites. They will impersonate company and service notifications and manipulate the target end users into believing that they are interacting with safe content.
The .ROGER virus can be embedded in hacker-controlled sites that are hosted on legitimate sounding domain names and designed accordingly. When the hackers send the virus files over email messages the files will usually be linked or attached directly.
An alternative way is to create virus-infected files which lead to the .ROGER ransomware infection. Dharma malware samples are commonly found within dangerous app installers of popular software which are often downloaded by end users. Another popular strategy is to create malware-infected documents across all popular file formats. When they are opened by the victim users a prompt will be spawned which will request that the built-in macros are run. All of these files can be uploaded to file-sharing networks and download portals.
.ROGER Virus Files – Technical Analysis
Like previous versions of the Dharma ransomware family as soon as the threat is started a built-in behavior pattern will be started. Its actions will depend on the specific hacker instructions or local computer conditions. Taking the experience of previous versions the .ROGER virus will probably follow the typical modules as expected from this type of viruses.
Common modules include the changing of important system settings. Depending on the exact behavior pattern this can be the boot options — the virus will be run as soon as the computer is started. In some cases this can also block access to the recovery boot options.
What’s particularly dangerous is that Dharma ransomware such as the .ROGER virus samples are commonly used to distribute other malware as well — often they are Trojans, cryptocurrency miners and etc.
Most of the advanced .ROGER virus can also lead to Windows Registry changes which will cause a lot of dangerous consequences:
- Existing entries can be modified which will cause application errors
- The .ROGER virus may create new entries for itself. This is usually related to a process called “persistent installation” — where the virus will be started every time the computer is started
- If any user settings or configuration files are changed then the overall system performance will degrade
- The users can experience random errors and data loss
When all of the built-in modules have finished running the encryption phase will start. It uses a strong cipher in order to affect target user files. Commonly this includes the following files:
archives, documents, databases, multimedia files, backups and etc.
Following the tradition of previous threats the affected files will be renamed with the .ROGER extension. A ransomware note will be created to manipulate the users into paying a decryption fee to the hackers. The captured samples will quote a hacker contact email address which is backdata.company@aol.com.
