Hikvision on Minimizing Backdoor Security Concerns, Hackers Exploiting Vulnerabilities in Retail

 

The Security magazine article, “Defending Against Ransomware: The Growth of Targeted Attacks,” outlines the evolution of ransomware malware attacks and provides best practices to curb this security concern.

From the article: “The evolution of ransomware attacks continues a trend in which cybercriminals are moving away from mass-volume, opportunistic ransomware attacks and are focusing their efforts on enterprises that they believe will pay their ransoms.” The article added that new ransomware, such as variant Sodin (also known as Sodinokibi), is creating challenges for enterprises. Even though Sodin functions like other ransomware threats, it becomes more troublesome, according to the article, because it exploits a recently announced critical vulnerability that allows for arbitrary remote code execution.”

Best practice tips to prevent malware and increase protection include:

  • Store a backup of critical data off the network on a separate device for easier restoration of data if a ransomware attack occurs. The article added, “Backup systems regularly, scan backups for infection and run data restoration drills so that recovery from an attack is routine and predictable.”
     
  • Ensure tools are operating with the latest updates, including your network, anti-virus protection, and anti-malware tools.
     
  • Implement network segmentation, which Hikvision’s cybersecurity director talks about in this Hikvision blog.

Hikvision covers other cyber threats, such as backdoor security concerns and hackers exploiting vulnerabilities, in this blog: “Hackers Exploit Vulnerabilities, More than 60% of Retailers Have Experienced Security Breach.”
