Inferences: 

  • Human-driven targeted attacks are increasing year after year. Therefore, implementing manual threat hunting along with classical alert-driven monitoring will be efficient to detect such attacks. 
  • As more than 14% of high-severity incidents are related to malware, the need for comprehensive anti-malware protection is imperative. 
  • Red team exercises are an efficient approach to assessing the security of an organization.  
  • Using the MITRE ATT&CK framework for threat detection to track the cyber adversary tactics will strengthen the organization’s security.
