How Does .MOLE03 Ransomware Virus Infect

One of the most common strategies is the creation and coordination of crafted spam email campaigns that feature social engineering tricks. The aim of hackers is to trick victims into infecting themselves with the .MOLE03 ransomware virus by opening file attachments or links inserted in the body content. The messages pose as being sent from legitimate companies or government institutions and are usually done by adding graphics and text that resemble the real companies.

The .MOLE03 virus payload can also be hosted on hacker-controlled or hacked download sites that may pretend to be distributing legitimate sources. Based on the infection plan the the .MOLE03 ransomware virus code can be bundled in software installers or documents.

Other methods include direct hacker attacks, browser hijacker deployment, and automated software vulnerability attacks.

Infection Flow of .MOLE03 Ransomware Virus

The .MOLE03 ransomware virus derives from the Mole ransomware family and appears to be third on a roll after .MOLE and Mole00-02 ransomware.

It drops its malicious executable file on the system, and once it is running on it, the ransomware performs a sequence of malicious system and data modifications. Thus it may drop or create additional malicious files and hide some of them in essential Windows folders like %Temp%, %AppData%, %UserProfile% and %Roaming%. The .MOLE03 ransomware virus can establish an online connection with website or host controlled by cyber criminals so they can receive more details about the system and the decryption key which is generated during the encryption process.

The encryption is realized via RSA 2048 and AES 128 cipher algorithms. It is applied to each file that has one of the file extensions predefined in .MOLE03 ransomware target data list. As its predecessors this Mole variant is believed to have the same list of target file extensions in its code which are:

.0 .1CD .1PA .1ST .2BP .36 .3DM .3DS .3FR .3GP .411 .4DB .4DL .4MP .73I .7Z

The .MOLE03 ransomware virus name comes from the malicious extension of the same name .MOLE03 that renames each encrypted file. Once the ransomware transforms the original code of all target files they become unable to be open with no software except the ransomware decryptor. For the purpose users will need the unique private decryption key which is possessed by hackers. Unfortunately, they demand 1.0 bitcoins ransom for the key which is an insane price as 1 BTC is currently 2758.70 US Dollar with rising trend.

Also .MOLE03 crypto virus drops a specially crafted file that contains ransom message from hackers to infected users. The file is named _HELP_INSTRUCTION.txt and is believed that the ransomware creates new values in Windows Registry to set the automatic ransom note appearance at the end of infection. All that is reads is:


All of your files are encrypted with RSA_2048 and AES_128 ciphers.
