The rise in impersonation attacks was a standout theme, said Mimecast cybersecurity strategist Matthew Gardiner. “These are difficult attacks to identify without specialised security capabilities, and this testing shows that commonly used systems aren’t doing a good job catching them.”
The failure of email gateways to spot attacks meant that “targeted malware, heavily socially engineered impersonation attacks, and phishing threats are still reaching employee inboxes”.
