The target data list of Dharma ransomware is not announced officially but it probably includes commonly used data formats for saving data.

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

The notes usually display text that informs victims about the caused damage by the ransomware, how much the ransom is and where it could be transferred. According to security researchers, the Dharma ransom note may be named Readme.txt or Readme.jpg. The text displayed on it may read the following:

//hallo, our dear friend!
