Twenty percent of Office 365 users who receive an email with a malicious link, clicks on the link within the first 5 minutes, according to a report from Microsoft. For the report, the software giant analyzed billions of emails that were sent between January and September this year.
Attackers have switched from sending emails with malware attachments to targeted phishing campaigns, according to Microsoft. During research for the report, the company analyzed 300,000 phishing campaigns. Eight million cases were CEO fraud. Not only the scale of the attacks increases, also how quickly users click through on malicious links.
Microsoft states it has improved the detection of phishing mails, but that there is no solution that can stop all threats.
