NM4 Ransomware Distribution

The captured samples of the NM4 ransomware are limited in number at this time. This does not give a clear indication of the distribution methods employed by the hackers. We suspect that the NM4 ransomware is distributed using one of the following methods:

  • Direct Hacker Attacks Automated or manual intrusion attempts may be attempted against the predefined targets. In the last few years most of the ransomware strategies use automated frameworks that use software exploits to gain entry into internal networks and computers. Computer users can protect themselves by always applying the latest software updates of all installed applications and using a quality anti-spyware solution that is able to protect to protect them from any incoming threats, as well as remove easily any active infections.
  • Infected Installers – Malware such as the NM4 ransomware are often bundled with software installers of popular trial or free versions of applications, games, patches, utilities and etc. The hackers usually take the official packages from their original source and repackage them with the malicious code.
  • Hacker-controlled Download Sites and P2P Networks – The computer hackers behind the ransomware usually distribute the files directly or bundled with software installers (see above) on hacked or owned download sites. They may pose as official sources or sponsored sources of the applications or legitimate download portals. In the last few years much of the BitTorrent trackers and other P2P networks have also been infested with various types of malware, including dangerous ransomware strains such as this one.
  • Email Spam Messages – The criminals use email spam messages as one of the primary ways of spreading malware. Depending on the attack campaign they may send the ransomware binary either as an attachment or linked in the body of the message. Other tactics include the use of malicious scripts embedded in fake documents or infected software installers are also used by the hackers.
