Trend Micro has said that it has blocked over 33.6 million cloud email threats in 2021, a 101% increase on the previous year. This stark increase in attacks proves that email remains a top point of entry for cyberattacks.

Each year we see innovation in the threat landscape and an evolution of the corporate attack surface, but each year email remains a major threat to organizations. The best shot defenders have at mitigating these risks is by taking a platform-based approach, to shine a powerful light on threats and deliver streamlined prevention, detection and response without limits,” said Vijendra Katiyar, Country Manager, India and SAARC, Trend Micro.

The data was collected over the course of 2021 from products that supplement native protection in collaboration platforms such as Microsoft 365 and Google Workspace.

The Trend Micro Cloud App Security Threat Report 2021 reveals that 16.5 million detected and blocked phishing attacks, a 138% increase as the hybrid workforce continued to be targeted. There were 6.3 million credential phishing attacks, a 15% increase as phishing remains a primary means of compromise, whereas 3.3 million malicious files were detected, including a 134% surge in known threats and a 221% increase in unknown malware.

More positively, ransomware detections continued to decline by 43% year-over-year. This could be because attacks are becoming more targeted, along with Trend Micro’s successful blocking of ransomware affiliate tools such as Trickbot and BazarLoader.

Business email compromise (BEC) detections also fell by 11%. However, there was an 83% increase in BEC threats detected using Trend Micro’s AI-powered writing style analysis feature, indicating that these scams may be getting more sophisticated.
