"Email Is the Top Vector for Cyberattacks"
According to a report from Tessian, 40 percent of business emails contain unwanted content. In addition, email is currently the most common method of delivering cyberattacks. Ninety-four percent of organizations experienced a spear phishing or impersonation attack this year, and 92 percent experienced ransomware attacks via email. In the first nine months of 2022, the most common type of advanced email attack was impersonation, in which attackers attempt to create legitimate-looking email addresses. This type of attack is also the most concerning email threat to security leaders. In 2022, security leaders reported an average of 148 impersonation attacks, 141 spear phishing attacks, and 138 email-based ransomware attacks. Ransomware remains a top threat, with 92 percent of global organizations experiencing at least one email-based ransomware attack in 2022 and 10 percent of security leaders surveyed reporting receiving over 450 email-based ransomware attacks since January 2022. Most organizations use a Secure Email Gateway (SEG) or native security from a cloud provider to keep employees secure on email. However, according to the report, 62 percent of security leaders believe advanced email threats bypassed SEGs in 2022. In addition, 99.5 percent of respondents believe Artificial Intelligence (AI) and Machine Learning (ML) can enhance and improve email security, with security leaders citing faster threat detection (66 percent) and more accurate threat detection (56 percent) as the top two AI benefits. This article continues to discuss key findings from Tessian's email security report.
