Top Exploited Vulnerabilities

Check Point stated that Web Servers Malicious URL Directory Traversal is the most commonly exploited vulnerability in October 2021, affecting over 60% of organizations globally, followed by Web Server Exposed Git Repository Information Disclosure, impacting 55% of organizations worldwide, and HTTP Headers Remote Code Execution with a global impact of 54%.

“The Apache vulnerability only came to light early in October and is already one of the top ten most exploited vulnerabilities worldwide, showing how fast attackers move. This vulnerability can lead threat actors to map URLs to files outside the expected document root by launching a path traversal attack. It’s imperative that Apache users have appropriate protection technologies in place. This month, Trickbot, which is often used to drop ransomware, is the most prevalent malware. Globally, one out of every 61 organizations is impacted by ransomware every week. That’s a shocking figure, and companies need to do more. Many attacks start with a simple email, so educating users on how to identify a potential threat is one of the most important defenses an organization can deploy,” said Maya Horowitz, VP of Research at Check Point Software.


Prakash BellExplaining on how organizations can mitigate the significance risks from evolving malware threats, Prakash Bell, Customer Success Head and Security Engineer Team Lead, Check Point Software Technologies, India, said, “Several Malwares are very difficult for a “non-technical” eye to recognize. Therefore, if you suspect you have been infected it would be wise to consult with a security professional or use third party tools and protections designed to identify, block and even remove this threat from your computer.”

Prakash Bell also recommended certain security precautions which include:

  1. Go to Check your username in the OS
  2. Go to /Users/[username]/Library/LaunchAgents directory
  3. Check for suspicious filenames in this directory (example below is a random name) /Users/user/Library/LaunchAgents/com.wznlVRt83Jsd.HPyT0b4Hwxh.plist
  4. Remove the suspicious file

Some preventive measures to both Mac and Window users:

  1. Not open suspicious attachments
  2. Avoid visiting suspicious websites
  3. Use 3rd party protection software to help identify and prevent malicious behavior on their computer
