Distribution of HSDFSDCrypt Ransomware

The HSDFSDCrypt 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 HSDFSDCrypt 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 HSDFSDCrypt Ransomware infection.

The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the HSDFSDCrypt 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 HSDFSDCrypt 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 HSDFSDCrypt Ransomware

HSDFSDCrypt ransomware is a newly released threat which has just been sighted by security analysts. At the moment a detailed analysis is not yet available however the initial code check does not give out a correlation between it and any of the famous malware families. This means that the hacker or criminal collective behind it have created it from scratch. At the moment there is no information available on their identities.

The collected samples associated with the HSDFSDCrypt ransomware showcase that only a basic engine is integrated in them. If the attacks prove successful the virus can be easily updated to include other modules including such as the following:

  • Information Harvesting ‒ The criminals can steal sensitive data before the encryption process is started.
  • Trojan Module ‒ It can be used to spy on the victim machines and overtake control on request.
  • Additional Virus Delivery ‒ The HSDFSDCrypt ransomware can be used to deploy other malware to the target computers.

Like previous malware samples it uses a list of target file type extensions built into the infection module. Data which may become affected includes the following:

  • Backups
  • Configuration Files
  • Images
  • Videos
  • Music
  • Databases

Once all encryption processes have complete the affected data is renamed with a random extension. It is possible that the strings have been generated using harvested information from the victim system. A note is created in a Wo_sind_meine_Dateien.html file which reads the following:
