.stone Files Virus – How Does It Infect and What Does It Do?

The .stone files virus has been identified as a strain of

STOP ransomware. The main purpose of this threat is to encode valuable personal files as a precondition for ransom extortion. It has recently been spotted on the malware scene. So keep in mind that the ransomware is lurking across the web in active attack campaigns.

A common practice used by hackers who distribute ransomware threats like .stone is to launch massive email spam campaigns against users worldwide. The emails that are part of such campaigns characterize with the following elements:

  • A link to compromised web page that is set to download and execute infection files directly on the PC. The URL address to this page may be presented in the form of an in-text link, banner, image, button or full URL address.
  • A malicious file attachment that is presented as legitimate document by the text message. It could be uploaded in a .rar or .zip archive. Such a file could be set to evade active security measures and trick you into running the ransomware on your PC.

The moment the payload file of STOP .stone is started on your system, the ransomware becomes able to apply a vast number of malicious modifications that disrupt system security, contribute to its persistence and enable it to complete the encryption process.

Once .stone ransomware reaches the encryption phase it activates a built-in cipher module which scans the system for certain types of files and encodes them with the strong cipher algorithm Salsa 20. When the original code of target files is transformed, the files receive the extension .stone and remain inaccessible.

Unfortunately, it is likely that all common files that are listed below are among the targets of this nasty ransomware:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

Since the ransomware restricts yous access the data stored by .stone files, it tries to blackmail you into paying hackers a ransom fee. For the extortion, the threat drops a ransom message (_readme.txt) and loads it on your screen. It has the following text:
