Distribution of .udjvu Ransomware Virus

The so-called .udjvu ransomware is a devastating crypto virus that has been recently released in attack campaigns against computer users worldwide. Threat actors could be utilizing widely used tactics of distribution to infect computer systems.

One of the methods that may be used by the malicious actors behind .udjvu ransomware includes the coordination of SPAM email messages — they are used to spread the threat by sending out messages that pose as legitimate notifications sent by popular Internet portals or services that the targets may use. The virus files can be either directly attached or linked in the body. They can also be uploaded to fake download sites which are designed to appear like any of the popular Internet portals or vendor download sites. The malicious actors may use similar sounding domain names, certificates and hijacked design and contents to coerce the victims into thinking that they are accessing the legitimate address.

Another way that the threat may spread is through infected payloads — the use of various files that are infected with virus code. A popular example is the malicious document which can take any form: presentations, rich text files, spreadsheets and databases. Once they are opened by the victims a notification message will pop-up asking the target users to enable the built-in scripts. If this is done the virus infection will follow. The other popular technique is the inclusion of the code in application installers. They are malicious copies of legitimate setup files of popular end-user programs that have been modified with the PHOBOS ransomware code.

Ransomware files are also popularly spread by fake user profiles — they can post to community forums or social media accounts. The criminals can utilize both fake or stolen identities to increase the number of infected users.

In certain cases, the criminals may also be distributed via malicious browser plugins — additions to the most popular web browsers that are advertised as useful. The plugins are uploaded to the official repositories and often make use of fake or hijacked user reviews and developer credentials. Once they are installed by the users they will execute their built-in instructions that in many cases leads to the .udjvu ransomware virus infection in the end.

Impact of .udjvu Ransomware Virus

This ransomware virus is named after an associated extension appended to all corrupted files. The threat has been reported to belong to the infamous threat family STOP. Once .udjvu crypto virus manages to run its payload on your system, it starts infecting various system components in order to reach data encryption phase that enables it to encode valuable files.

For the encryption process, .udjvu ransomware virus utilizes combination of two sophisticated cipher algorithms – AES and RSA. Unfortunately, during the encryption phase each target is transformed in a way that prevents its normal usage. Among the targeted files could be:

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

All corrupted files appear with the extension .udjvu at the end of their names. As most of these files are supposed to store valuable data, hackers attempt to blackmail you into paying a ransom for their decrytper.

The extortion process is realized via ransom note. So following encryption, the threat drops a text file named !readme.txt to inform victims the following:
