Distribution of Hermes 2.1 Ransomware

At the moment the captured samples associated with the Hermes 2.1 ransomware are limited. We suspect that the main attack wave is currently being planned. It is very likely that the hacker operators are going to utilize the most popular infection methods.

A popular way is the use of email messages which can spread the infection files or link to them in different ways. The most rudimentary approach is the attachment of the virus files directly with the messages. They can also be hyperlinked in the body contents or the signature. The criminal operators have the ability to use payloads which carry the Hermes 2.1 ransomware code in themselves.

Popular examples documents of different types ‒ rich text documents, spreadsheets, databases, presentations and others. The files contain scripts that when enabled by the users download and execute the virus file. In the most typical case the users will see a notification prompt which will ask them to enable the built-in scripts. If this is done the infection commences.

Browser hijackers are very useful when distributing malware of this type. They represent dangerous web browser plugins that seek to infect the most popular applications: Mozilla Firefox, Safari, Opera, Microsoft Edge, Google Chrome, Internet Explorer and others. Once this is done the victims will find that their settings have been changed. The hijackers redirect the users to a specific hacker-created web page by pointing the default home page, search engine and new tabs page to it. The hacker sequence also hijacks sensitive data from the compromised machines: cookies, images, videos, documents, archives, backups and etc.

Impact of Hermes 2.1 Ransomware

The Hermes 2.1 ransomware is a new iteration of the Hermes malware family. The security analysts note that at the moment the identity of the hackers is not known. There is no available information about their schemes and patterns and it cannot be judged if they are the same hackers behind the previous strains associated with the Hermes ransomware family. If they are a new malicious collective then the code to the core malware family is probably up for sale on the hacker underground markets. If this is so then more versions and updates are likely to follow.

The captured samples seem to display the same mechanisms of intrusion. It can follow any pre-infection sequences which might include the following:

  • Trojan Module ‒ It can be used by the criminals to remote control the compromised computers. The hackers can take over control at any given time.
  • Surveillance ‒ The hackers can spy on the users. This includes not only their on-screen interactions, but also keystrokes and mouse clicks.
  • Additional Malware Delivery ‒ If customized the new Hermes 2.1 ransomware can help deliver additional threats to the victim computers.
  • Registry Changes ‒ The Hermes 2.1 ransomware can invoke changes to the Microsoft Windows registry. As a result applications may fail and the computer may experience performance issues.
  • Persistence Installation ‒ Hermes 2.1 ransomware can install itself in a way which actively counters and disables any manual removal attempts.

Once this is done the Hermes 2.1 ransomware starts its encrypiton process. In comparison with previous versions complex renaming schemes are no longer utilized. Like other viruses it uses a prebuilt list of target file type extensions. Examples include: images, videos, photos, documents, archives, backups, configuration files and etc. When all files have been processed they receive the .HRM or .RSA extensions. In some cases a random name generator can be used as well.

a ransomware note is crafted in a DECRYPT_INFORMATION.html file which reads the following message:
