DiskDoctor Ransomware – Distribution

The payload file that triggers DiskDoctor ransomware infection could be spread with the help of shady techniques that trick users into infecting their systems. Mainly are used deceptive email attachments and compromised web pages.

Email attachments that deliver the payload on target computer systems usually are part of emails with spoofed sender and address. A common practice of cybercriminals is the creation of email campaigns that impersonate representatives of a well-known institution or business services including PayPal, DHL, FedEx, and Amazon. This way they attempt to trick users into opening malicious email attachments on their PCs. Such an action leads to an infection with DiskDoctor ransomware.

Some of the emails used for the spread of DiskDoctor’s payload may lack file attachments but present in-text links instead. In this case a click on the link opens a compromised web page that may be set to cause an unnoticed download of malicious scripts on the device. With the help of these scripts the ransomware infection code sneaks into the system and becomes able to plague it.

DiskDoctor Ransomware – Overview

DiskDoctor ransomware is mainly meant to encrypt files that store valuable information. But before the encryption process, it needs to establish its malicious files on the system and perform several system modifications.

Malicious files and objects associated with this new Scarab ransomware version dubbed DiskDoctor may be dropped or created in the following system folders:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%
  • %Windows%

Some of the files may be self-deleting executables that stay on the system only during the infection process. Others are likely to remain steadily on it so they can start the ransomware on each system start. In order to set its malicious files to auto-execute on each system start, DiskDoctor exploits the functionalities of Run and RunOnce registry sub-keys.

A specific trait of DiskDoctor crypto virus is the ransom note it uses to instruct infected users how to act further if they want to obtain the decryption key. The note is contained in a TXT file called HOW TO RECOVER ENCRYPTED FILES.TXT that could appear on the PC screen at the end of the attack. And here is the message it reads:

Warning all your files are encrypted !!!
To receive the decoder, you must send an email to the email address with your personal ID:
[email protected]
In response you will receive further instructions.
ATTENTION !!!
* Do not attempt to uninstall the program or run antivirus software.
* Attempts to self-decrypt files will result in the loss of your data.
* Decoders of other users are incompatible with your data, as each user has a unique encryption key.
Your personal identifier:
6A02000000000000***95611F

→vssadmin.exe delete shadows /all /Quiet
