.hrm Ransomware – Distribution Techniques

The .hrm ransomware has been spotted in a very limited attack campaign which doesn’t give out the main infection method used to spread the samples. We assume that the most popular strategies are to be used.

One such method is the distribution of email SPAM messages which contain phishing instructions making it possible to confuse the recipients into thinking that they are receiving a legitimate notification from a well-known company or service. The virus files are to be released through the body contents or file attachments.

A similar method relies on the construction of fake web sites that pose as legitimate product landing pages, search engines and download portals. Any interaction with elements used by them can lead to the infection. In order to lure in the victims into visiting these sites the hacker groups will host them on similar sounding domain names and including security certificates.

The .hrm ransomware infection scripts can be placed in payload carriers of which there are two popular types:

  • Application Installers — The criminals can place the code in hacker-made setup files. This procedure is very popular as it only requires the hacker collective to acquire the legitimate installer and modify it to include the .hrm ransomware installation code.
  • Malicious Macros in Documents — The other strategy is to include the installation instructions in the document macros all popular file types: spreadsheets, databases, text files and presentations. Whenever they are opened by the victims a notification prompt will appear asking the users to enable them in order to “correctly” view the document contents.

All of these files can be spread via file-sharing networks like BitTorrent. These platforms are very popular for distributing both pirate and legitimate contents.

Larger campaigns can be coordinated via browser hijackers which represent dangerous plugins made for the most popular web browsers. They are widely available on the associated web browser repositories using fake user reviews and hacker-made developer credentials. The posted descriptions will promise performance optimizations and new features. As soon as they are installed on the target computers the default settings will be changed to redirect the victims to a hacker-controlled site. At the same time the .hrm ramsomware will also be delivered.

.hrm Ransomware – Detailed Analysis

At the moment the analysis reveals that the threat is part of the BlackHeart ransomware family. This means that it is based on a modular platform which allows every single campaign to be feature a distinct behavior and built-in features. The future versions will probably be programmed to contain the most popular modules as observed with other infections:

  • Machine Identification — Each infected computer can be assigned an unique ID which can differentiate the hosts from each other. It is usually generated by an algorithm that takes the input values from the list of installed hardware components, user settings and operating system environment values.
  • Personal Data Extraction — An additional action done by the information gathering engine is the acquisition of personal information that can directly reveal the identity of the users. The engine can be programmed to extract such as the following: their names, address, location, interests and even any stored account credentials.
  • Boot Options Modification — Many ransomware like the .hrm virus are able to modify the Windows boot options in a way which makes the samples load automatically when the computer is powered on. When the configuration files have been altered the configuration files it will be very difficult to remove the active .hrm ransomware infections as the recovery menus will be blocked. This makes manual user removal guides useless and the only effective way to remove such threats will be to use a quality anti-spyware solution.
  • Windows Registry Changes — The virus engine can be configured to modify the entries part of the Windows Registry. This can cause serious issues to the operating system — certain functions may no longer work and the overall stability and performance can degrade. When third-party applications are affected then they can quit with unexpected errors if their configuration files and Registry entries are affected.
  • Security Bypass — Once the .hrm ransomware has been installed on the target computers it can be used to look for security software that can block the virus engine. They can be bypassed or entirely removed and the services that can be blocked — anti-virus programs, firewalls, debug environments and virtual machine hosts.
  • Additional Payload Delivery — Some of the ransomware variants that are similar to the .hrm virus can be used to install other malware such as Trojans, miners and hijackers.

Depending on the exact configuration other behavior patterns can be run as well.

.hrm Ransomware – Encryption Process

The .hrm Ransomware encrypts user data with a strong cipher according to a built-in list of target data extensions. In most cases it will target the most popular ones:

  • Archives
  • Backups
  • Documents
  • Images
  • Videos
  • Music

The victim files will be renamed with the .hrm extension and a lockscreen displayed to coerce the victims into paying a decryption fee to the hackers. The message reads the following:

All your files have been encrypted!

All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us the e-mail:
nomoreletters@protonmail.ch and sent personal ID KEY:

You have to pay for decryption in Bitcoins. The price depends on how you write to us. After payment we wiill send you the decryption tool that will decrypt all your files.
