.crypt! Ransomware – Distribution Techniques

The .crypt! ransomware appears to be a modified version of the CrySiS/Dharma source code engine. There is no information available about the identity of the hacker collective behind it — as this virus is one of them most popular examples of derivative malware we presume that the criminals have ordered a custom strain from the underground hacker markets. The ready-made .crypt! ransomware samples may be send to the victims using the most popular tactics.

One of the most widely used choices remains the creation and coordination of email phishing campaigns — these messages will pose as legitimate notifications sent by companies, colleagues, systems and etc. They are configured to use similar design elements and contents as the real ones. They will include links to the dangerous files or present them as direct attachments.

The hackers can additionally create malicious web sites that impersonate legitimate and popular Internet pages: search engines, download portals, software product landing pages and etc. They are hosted on similar sounding domain names and may include security certificates — they can be both stolen or bought with fake or stolen credentials. Most of the similar ransomware infections also utilize the method of payload delivery of which there are two main types:

  • Malicious Application Installers — The hackers can produce infected software installers by taking the legitimate files from their official sources and modding them with the relevant code. Often popular software that are downloaded and used by most computer users is chosen: productivity and office apps, creativity suites and even games. Whenever they are run the virus infections will follow.
  • Dangerous Documents — The other popular method is to embed the virus installation scripts in documents of all popular types: text documents, spreadsheets, presentations and databases. The code is placed in the macros which will present a prompt as soon as the document is opened. The victim users will be requested to enable them by explaining that this is required in order to correctly view the file.

Both the standalone virus files and that payload carriers can be spread via file-sharing networks like BitTorrent where both pirate and legitimate files are distributed. Global ransomware releases are also done by inserting the virus installation code in browser plugins — the resulting threat is called a browser hijacker. They are done by creating extensions for the most poular web browsers and are usually uploaded to the relevant repositories. They contain not only the .crypt! ransomware code but also other malicious mechanisms which are engaged as soon as they are installed by the computer users. To make them appear as legitimate and safe plugins their descriptions will include elaborate promises of new feature additions or performance optimizations. In addition fake user reviews and developer credentials will probably be presented.

.crypt! Ransomware – Detailed Analysis

The .crpyt! ransomware as a modified version of the Dharma/CrySiS ransomware family probably exhibits the same modular approach as previous versions. This version is distinctive as it does not produce the regular signatures as observed with other similar versions. This means that it is much more difficult to detect by anti-virus products until its identification information is introduced into their malware information database.

We anticipate that the basic behavior pattern will be observed. It will call the main infection engine to carry out the configured malware actions. A list of the most popular ones is the following:

  • Information Gathering — The engine can be programmed to scan the infected computers for any data that might be useful to the attackers. This is especially dangerous when it comes to personal information that can directly expose the identity of the victim users. This is done by searching for strings that contain a person’s name, address, phone number, interests and even stored account credentials. This is extremely dangerous as Dharma ransomware samples can be instructed to interact with the Windows Volume Manager which allows it to access available network shares and removable storage devices.
  • Security Software Bypass — The .crypt! ransomware samples will search for security programs that can block or altogether delete the engines of security software. The list of usual applications includes anti-virus programs, firewalls, sandbox environments and virtual machine hosts.
  • Windows Registry Modifications — Once the .crypt! ransomware has bypassed security it will continue with modifications to the Windows Registry values. This is very dangerous as changes to these values will lead to severe performance issues. When individual applications or system service Registry entries are modified this may break certain functions from performing properly or lead to unexpected errors.
  • Boot Options Modifications — The .crypt! ransomware can be configured as a persistent threat which means that it will be set to automatically start itself when the computer boots. This will also block access to the boot options and recovery menus which are used with the manual user removal guides. This means that the victims will need to use a quality anti-spyware solution.
  • Data Removal — The engine can search for files that may be critical to the normal operation of the operating system and delete them. This is dangerous as this encompasses a wide variety of data: Restore Points, Backups and Shadow Volume Copies.
  • Additional Payload Delivery — Many ransomware threats of this malware family are programmed to deliver other dangerous payloads. One of the typical representatives is a Trojan horse infection which allows the hackers to take over control of the compromised machines. They can also spy on their activities and steal their files before the files are processed.

As the campaigns continue to proliferate we anticipate that other modifications to the behavior pattern might be committed.

.crypt! Ransomware – Encryption Process

Like previous Dharma malware samples the .crypt! ransomware will launch the encryption engine once all prior modules have finished running. It will probably use a built-in list of target file type extensions which are to be processed by a strong cipher. An example list can include the following data types:

  • Backups
  • Databases
  • Archives
  • Images
  • Music
  • Videos

All affected files will receive the .crypt! extension. The associated ransomware is crafted in a file called HOW TO DECRYPT FILES.txt.

Remove .crypt! Ransomware and Try to Restore Data
