Your email isn’t safe. Many serious threats make it through filters designed to prevent malicious emails from reaching user inboxes. Each one represents a risk to your business. Despite improvements in incumbent technologies, cybercriminals stay in business by embracing tactics such as email impersonation which often fools blocking systems and end users.
Email impersonation attacks increasing at an alarming rate
Email filtration systems and internet security software can help you keep you and your business safe, but you cannot depend on them. A recent email security risk assessment (ESRA) published by Mimecast illustrates the magnitude of the problem.
ESRA’s analysis shows that a total of more than 19 million spam emails; 13,176 emails containing dangerous file types; and 15,656 malware attachments were missed by the incumbent security and delivered to users’ inboxes. It also discovered 203,000 malicious links within just over 10 million emails that were delivered to inboxes — a ratio of around one unstopped malicious link in every fifty inspected emails.
Of the “inspected emails,” the number of email impersonation attacks has increased by 80 percent.
These are difficult attacks to identify without specialized security capabilities, and this testing shows that commonly used systems aren’t doing a good job catching them.
Quick Tip: A large number of malicious emails reaching yours and your employees’ inboxes. You should create a written online security policy and an active training program to help your employees know how to identify and respond to email impersonation attacks. These measures can complement your deployment of other security control can detect malware and prevent users from clicking on malicious links.
