ATLAS Ransomware Infection Flow

The infection process with ATLAS ransomware is initiated by an executable file that can automatically carry out different tasks. ATLAS ransomware may write new files and start them as a way to ensure its sustainability in the system. It is also likely to gather information about the infected machine contact a remote server controlled by crooks and send them the report.

Furthermore, the threat may add new values in specific registry keys as RUN and RUNONCE. By writing multiple new entries under these keys, ATLAS ransomware makes certain that the malicious files will be terminated each time the victim logs on the PC. The following four keys in the Windows Registry are probably contaminated:

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

The main goal of the ransomware is to locate certain files predefined in its encryption target data list and make them out of reach. For the purpose, it enforces a combination of two encryption algorithms – AES and RSA-512. During the encryption process all target files are encoded in such a way that they can be accessed only via the decryption key possessed by the hackers. The encrypted files are completely renamed and have appended the malicious suffix .ATLAS after their original extensions. As regards the file types object of enciphering they may be video files, audio files, Adobe .PDF files, databases, virtual drives, Microsoft Office documents.

Once ATLAS finishes the encryption process, it drops a file named ATLAS_FILES.txt which displays the ransom message. The whole ransom text reads:
