This quarter’s Mimecast Threat Intelligence Report found that impersonation attacks are on this rise, accounting for 26% of total detections.
Mimecast Limited has released its quarterly Threat Intelligence Report: Risk and Resilience Insights. The Mimecast Threat Intelligence Report includes analysis of 207 billion emails processed by Mimecast, 99 billion of which were rejected.
This research looks through the lens of the four main categories of attack types discovered in the quarter: spam, impersonation, opportunistic, and targeted. This quarter’s report found that impersonation attacks are on this rise, accounting for 26% of total detections – and now includes voice phishing or “vishing,” an advanced attack observed in this quarter, where threat actors use social engineering to gain access to personal and financial information via the victim’s telephone system.
Throughout the research, it was clear three industries were targeted the most by cyberattacks. Banking and legal, industries that are rich with sensitive information that yield results for threat actors and transportation, where state-sponsored threat actors seek to disrupt the logistical and supply capability of rivals.
This quarter’s research found that the majority of threats were simple, sheer volume attacks. Easy to execute, but not as easy to protect against as it shines a very bright light on the role human error could play in an organization’s vulnerability. Organizations need to take a pervasive approach to email security – one that integrates the right security tools allowing for greater visibility at, in and beyond the perimeter. This approach also requires educating the last line of defense – employees. Coupling technology with a force of well-trained human eyes will help organizations strengthen their security postures to defend against both simple and sophisticated threats”
