.p3rf0rm4 Ransomware – Distribution Techniques

The captured samples associated with the .p3rf0rm4 ransomware appear to belong to the Paradise family of viruses. This is a relatively new group of ransomware that are popular with hackers as customization options are frequently offered on the dark underground networks. There is no information available about the hacker collective behind the attacks, it is assumed that they might be inexperienced due to the choice of using a customized variant of a well-known threat.

The hackers can spread the threat by sending out phishing email messages which are sent in a large volume to the intended recipients. They are designed in order to replicate the design and contents of legitimate and well-known company and services. Through interaction with them or by accessing the attached files the virus infection can be invoked.

Another popular mechanism is the creation of malicious sites that are presented to the visitors as safe download portals, search engines and product landing pages. They may use similar sounding domain names and self-signed security certificates in order to appear as more legitimate.

Many of the .p3rf0rm4 ransomware infections can be caused by the use of payload carriers which are one of the most popular methods used by hackers. They aim to present files of various types that are frequently used by users by carrying inside them the virus deployment code. There are two main types:

  • Software Setup Files — The virus engine can be placed in software installers. The hackers make them by taking the legitimate files from their official sources and modifying them to include the relevant code. Usually the target applications are system utilities, creativity programs, office and productivity tools and etc.
  • Infected Documents — Macros that lead to the ransomware infection can be placed in the most popular document formats: presentations, rich text documents, databases and spreadsheets. Whenever they are opened a prompt appears that will ask the users to enable the built-in commands, usually the quoted reason is that this is required in order to correctly view the contents of the files.

Many of them are also shared on file sharing networks like BitTorrent which are used by computer users to share both legitimate and pirate content.

Larger distribution is usually made possible by the use of browser hijackers — dangerous web browser plugins which are usually uploaded to their relevant repositories. They are often added with fake user reviews and developer credentials that promise greater enhancement of the programs. As soon as they are installed by the users the .p3rf0rm4 ransomware will be installed.

.p3rf0rm4 Ransomware – Detailed Analysis

The Paradise family of viruses of which the .p3rf0rm4 ransomware is part of is known to have a modular framework. This makes it possible for the engine to conduct various types of malware activities.

Many of them choose to begin the infection with a data harvesting module. It is primarily used to expose the identity of the victim users by looking for strings such as their name, address, interests and even any stored account credentials. The same mechanism can be applied in order to generate an unique ID which can be applied to every affected computer.

The collected information can be used by another module known as security bypass that can search and remove any programs and services that can block the .p3rf0rm4 ransomware from running. This is done by scanning the memory and hard disk contents for them: anti-virus programs, firewalls, intrusion detection systems, virtual machine hosts and etc.

As soon as the virus has ben deployed on the systems it will be able to cause a lot of system changes. Many of them are related to the Windows Registry where new values can be made and existing ones can be modified. This effectively leads to severe performance issues, data loss and unexpected errors. Viruses like this one can hook up to existing processes or create new ones, including ones with administrative privileges.

Additional threats can be deployed to the victims. One of the most common ones are the Trojans — they establish a persistent installation to a hacker-controlled server. As a consequence the hacker controllers will have the ability to take over control of the machines, steal user data and spy on the victims in real-time. Other components can be added at any time by the hackers by uploading the new modules and relaunching the attack campaigns.

.p3rf0rm4 Ransomware – Encryption Process

Like other popular malware samples the .p3rf0rm4 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 are renamed with the .p3rf0rm4 extension. A ransomware note will be produced in a text file called “Instructions with your files.txt”.
