Bad Sender: The Importance of Sender Reputation

Written by Jeremy Fuchs | September 17, 2021

An easy way to determine if an email is suspicious is by looking at sender reputation. It’s no wonder, then, as we found in our 1H Cyber Attack Report, that 84.3% of all phishing emails do not have a significant historical reputation with the victim. Further, 43.35% of all phishing emails come from domains with very low traffic.

To the naked eye, however, there may not look to be much of a difference between a low reputation sender and a high reputation sender. Take a peek at these two emails. One is legit, one is not. 

 

 

High reputation and low reputation emails look identical. End-users are tasked with figuring out which is real and which is not. Can you figure out which is which?

(Hint: Check the stilted language in the first one. That's a big clue.)

Leaving harried end-users to figure out the difference will lead to clicks on the malicious one. Utilizing sender reputation, along with advanced AI, is critical for stopping these attacks before they reach the inbox.
