My company started with mandatory cybersecurity trainings for all employees. The training tool sends out automated emails to remind you when you have to do a new part of the training.
These emails, from a cybersecurity course, followed all the rules of being a phishing email:
- Sent from a non-company server
- Had a big red button to click here
- Urged you to take action ("You have 5 days to complete your training")
IT decided to fix that, by adding a line to the emails that this email is really from our company. Like a phisher wouldn't think of saying "nah, trust me bro, I'm totally legit"
