  2. Allow for hackers to control your AVTECH DVR system and use it to conduct attack against other server (DDOS, etc attack)
  3. Allow for hackers to access your internal network through your AVTECH CCTV System, and access to unsecure confidential files, photos, video, images, etc.
  4. Continuing to scan the internet looking for other uninfected system and attempt to infect them with the malware. This is how it continue to spread.
