Email security (3) - A must-see for companies that have introduced Office365! What cloud email security should be implemented now
Many cyber crimes are said to start with emails.
Although companies have introduced email security products and are taking countermeasures, the current situation is that attackers are also trying to infiltrate using all possible means.
In particular, the number of companies using Office 365 has increased significantly, and simultaneous attacks against multiple targets have been carried out.
Unknown threat detection and analysis of various file types are important for the secure use of Office 365.
In this article, we analyze the actual state of targeted attacks and the gaps between current security measures, and introduce Trellix (formerly FireEye) Email Security solutions that are effective for companies that are considering introducing Office 365.

How are you parsing the emails after the attack emails are sent?
(1) Current state of cyberattacks using e-mail
91% of cyberattacks start with receiving malicious emails. We are changing the method from attaching malware to phishing sites using URLs. Many organizations are also victims of spear phishing, which accounts for 84% of the total. From this, we can see that attacks that do not use malware are increasing, and attackers are changing their method from attaching malware to phishing sites using URLs. Therefore, there is a need for a solution that can not only inspect attachments, but also thoroughly inspect URLs in emails for maliciousness.

Therefore, there is a need for a solution that not only inspects attachments, but can also inspect in detail whether URLs in emails are malicious or not.
In the following chapters, we will introduce the results of a survey by Trellix (formerly FireEye) on the number of phishing attacks spoofing Microsoft, and the detection results of Trellix (formerly FireEye) Email Security regarding Office 365 bypass.
