I was reading through a deep dive by Threatcop on the risks of email spoofing, and it’s wild how "low-tech" these attacks can be while still causing massive damage. We spend thousands on firewalls, but a spoofed "From" header can bypass almost everything if the employee isn't trained to spot it.

One point in the Threatcop article that stuck out to me was how email spoofing damages a brand's reputation. Even if your systems aren't hacked, if a hacker sends a fake invoice from "your" domain to your customers, the trust is gone.

The article breaks down how attackers don't even need to "hack" a server anymore; they just exploit the way the SMTP protocol was originally built without built-in authentication.
