PayDay Ransomware – Distribution Techniques

The PayDay ransomware is being distributed using several popular methods. The captured samplse are low in number which signals that they may be early testing versions or development releases.

A popular strategy is the distribution of the virus files via phishing SPAM messages — they are powered through a campaign that is usually made to pose as notifications sent by well-known companies or services. As soon as they are opened the ransomware installation scripts can be run as they are frequently embedded in the multimedia elements in the body contents. An alternative is to directly upload them as attachments.

The other method is to create fake websites that will copy the design and content of legitimate download portals, product pages and other places where users frequently download software from. They feature stolen or hacker-made security certificates and use similar sounding domains names to the legitimate sites. All of this is done in order to confuse the users into thinking that they have accessed the real site even when they have mistyped it.

A popular mechanism for spreading malware is to create payload carriers of which there are two main types:

  • Infected Documents — A very popular technique is to insert the virus installation code in macros that are part of all popular document file types: text documents, spreadsheets, databases and presentations. When the necessary code is inserted a prompt will appear when the victims open them. It will request that the users open them up with the quoted reason that this is required in order to correctly view the file.
  • Application Installers — Another strategy is to create malicious setup files of popular software. They are made by inserting malicious code in them, like the documents strategy the hackers will choose applications that are frequently installed: system utilities, creativity products, office apps and etc. This is done by taking the legitimate files and modifying them to include the malware code.

All of these files can be spread via file-sharing networks such as BitTorrent — the torrent trackers are one of the most widely used places from where to acquire pirate software.

Larger infections can be orchestrated via browser hijackers — they represent malicious plugins which are released for the most popular web browsers. The hijackers are most commonly found uploaded to the relevant repositories often with fake user reviews and with elaborate descriptions. If downloaded and install the PayDay ransomware infection will be triggered.

PayDay Ransomware – Detailed Analysis

Once the virus infection has been triggered the associated behavior pattern will be executed. The virus does not appear to contain any code sources from any of the popular malware families. It is possible that the captured samples are still early releases and do not have the full functionality included.

A detailed analysis is not yet available, we have received confirmation that the ransomware engine is enabled and active however we anticipate that the large-scale attacks with the PayDay ransomware will include other actions as well.

It is possible that the typical ransomware system modification actions will take place:

  • Data Harvesting — The virus engine can retrieve sensitive information about the users and the machines. The collected data can be used to create an unique ID that is associated with the compromised computers. It is calculated by taking input values such as the id’s of the hardware parts, certain user settings and operating system values. The output is this unique infection ID. On the other hand this technique can also be used to directly expose the identity of the victims — their name, address, phone number, interests and even any stored account credentials.
  • Boot Options Change — The PayDay ransomware can modify configuration files and boot options in order to set itself to automatically start once the computer is powered on. This is one of the most popular tactics which is also blocks the use of manual removal guides as access to the recovery boot menus may be blocked.
  • Windows Registry Modifications — The engine can change the Windows registry values of both the operating system and third-party applications that may be installed. This can lead to serious performance issues and the inability to launch certain services or applications.
  • Files Modifications — The engine can search for data that may be essential to the operating system or the victim users. The PayDay ransomware engine can delete System Restore points, backups and other related data.
  • Additional Payload Delivery — The PayDay ransomware can be used to deploy additional threats to the compromised machines.

One of the most dangerous scenarios that such viruses can lead to is the set up of a Trojan infection which will establish a connection with a hacker-controlled server. It is used by the hacker operators to take over control of the infected machines, steal their files and cause other dangerous actions.

PayDay Ransomware – Encryption Process

The PayDay ransomware will launch the relevant encryption operations when all modules have finished running. Like other similar threats it will use a built-in list of target file type extensions such as the following:

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

What’s interesting about this particular virus is that it assigns a randomly-generated extension according to this pattern: .

The ransomware note which blackmails the victims into paying the hackers a decryption fee is created in a file called HOW_TO_DECRYPT_MY_FILES.txt containing
the following message:

============== !!!PAYDAY RANSOMWARE!!! ==============
Attention! All your files are encrypted with extension ***.
to decrypt your files – you must buy decryptor. Decryptor price – 200 USD.
If the decryptor is not bought within 3 day’s – files will be pernamently destroyed.
