Insider threats can put an organization at risk without even knowing it. In fact, the 2017 Global Threat Intelligence Center (GTIC) Quarterly Threat Intelligence Report indicates that 30% of all insider threats put an organization at risk without being aware of the vulnerability.

“Whether it’s an accidental insider threat, where an employee sends sensitive documents to a competitor‘s email or a negligent insider threat, where an employee downloads unauthorized software and spreads a virus through the company, organizations must have a cybersecurity plan in place to minimize these risks,” said Steven Bullitt, Vice President Threat Intelligence & Incident Response, GTIC, NTT Security.

“The GTIC Quarterly Threat Intelligence Report documents that in instances when organizations do not have a proactive cybersecurity plan in place, the consequences can be devastating. In fact, NTT Security has seen damages due to insider breaches reach more than $30 million USD. Even in organizations that have well-defined incident response plans, they often don’t provide adequate remediation provisions for insider breaches, leaving the organization less prepared to react quickly.“

Key findings

A summary of other key findings in the Q3 GTIC Quarterly Threat Intelligence Report include:

  • A notable increase in the number of security events during Q3 ’17 – up 24 percent from Q2 ‘17
  • The finance industry had the most detections for malicious activity in Q3 ‘17 – representing 25% of all cybersecurity attacks
  • Rounding out the top five targeted industries were: manufacturing at 21%, business services at 16%, health care at 13% and technology at 12%
  • Phishing campaigns and malware infections both increased by more than 40% over Q2 ‘17
  • Attacks from China moved up from the number three spot in Q2 ‘17 to number two in Q3 ‘17
  • As an attack source, India also made a huge jump from outside the top 10 up to number three, most likely due to outside actors leveraging vulnerable and/or compromised infrastructure.
