Distribution of Christmas Ransomware
The Christmas ransomware is a new virus which has been sighted in a limited attack campaign. At the moment the security researchers cannot determine the primary infection strategy. We presume that the most widely used tactics are going to be employed.
Among them are the email messages created in an automated way and sent to large lists of potential victims. The Christmas ransomware can be directly attached to the messages. This is one of the easiest way for the criminals to attempt the infection. However a lot of email hosting providers usually capture the signatures of the virus and as such discard such messages or label them as dangerous or spam. Other infection methods related to this one is the option of inserting hyperlinks in the body content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest. Redirects can redirect to hacker-controlled sites, infected payloads or other instances that can lead to an Christmas Ransomware infection.
The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the Christmas Ransomware. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.
The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind the Christmas Ransomware. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious addons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware, but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.
Impact of Christmas Ransomware
Computer security researchers uncovered a dangerous new threat called Christmas ransomware. At the moment the limited number of active samples and the still ongoing code analysis does not give out much details about the malware. So far the specialists have not been able to find a correlation between it and any of the famous malware families. This likely means that the person or group behind it have made it from scratch. The identity of the perpetrator(s) is not known at the moment.
The captured strains at the moment contain only a base ransomware engine which can be further updated, examples include the following:
- Information Harvesting ‒ The criminals can steal sensitive data before the encryption process is started.
- Additional Virus Delivery ‒ The Christmas ransomware can be used to deploy other malware to the target computers.
- Trojan Module ‒ It can be used to spy on the victim machines and overtake control on request.
Depending on the hacker configuration various pre-ransomware behavior patterns may be instituted as well. This includes Windows registry changes that may cause application failure, performance issues or boot up problems. Another possibility is the persistent installation of the Christmas ransomware virus. If this is done then the infection module will actively monitor the users behavior and any security software to defend itself from detection and removal.
Once all post-infection sequences have been complete the virus proceeds with the file processing. The Christmas ransomware uses a strong cipher to target the most widely used data. The most popular way is by using a built-in list of target file type extensions. Files that may be part of the process include the following:
- Images
- Videos
- Music
- Databases
- Backups
- Configuration Files
When the process is complete the processed files may be assigned a ransomware extension. It can be dynamically changed between the various iterations or it can bear the malware’s name ‒ “christmas”. To signal the infection the desktop wallpaper is changed to a dark forest image containing red text that reads the following:
