Electronic mail has become a standard for communications around the globe. Email can contain not just text, but can deliver documents, photos and videos and other media. Email allows people to contact others at any time and respond on their own schedule. Where previous methods of communicating with someone far away were expensive and time-consuming, email allows people to stay in touch no matter where they are as long as they can connect to the internet.
Yet email is not a fully secure communication medium, and a lot of people are just now figuring out just how vulnerable they may be. What was once considered a trusted means of communication has now become something to be suspicious of. For most users today, it is best to approach emails with a high degree of suspicion (zero trust), especially if they ask for personal information or contain links or attachments.
With email, someone could intercept the messages or even store messages without your knowledge or control. The smallest human error can have ripple effects that turn into waves of trouble because messages cannot usually be taken back. And then there are the threat actors, of which there are too many and they are far too clever.
Phishing has become a highly popular method of cyber-attack, probably because it works so well. It involves tricking people into giving away sensitive information like credit card numbers, social security numbers, and passwords. Phishing is fueling (phueling?) opportunities for malware infections and identity theft which can lead to financial loss, reputation damage and more. Any information an attacker can gain helps them get even more information and go deeper into the organization.
Protecting against phishing attacks requires vigilance and following best practices such as using strong and complex passwords, and two-factor or multi-factor authentication (MFA). Also, it is crucial that users avoid clicking on links in emails, and everyone should verify the email authenticity before responding, especially if sensitive information is involved.
To check the identity of the sender, mouse over (put your cursor over) the email address and it may show you the actual sender address. While the email may say the message came from somebody you know, you may find that the actual sender address is an obscure email address you don’t recognize.
Mouse over links in the email but don’t click on them. When you hover your cursor over the link, it may show you the actual url the link goes to. Like with email addresses, links can be named something other than the actual url. If it is a url or website name you recognize and trust, then type the url into your browser instead of clicking on the link, just in case.
Use multiple channels for communication. This means you should not just communicate with co-workers and others using email. It is always a good idea to have some other form of trusted means of communicating with someone, such as via telephone or a messaging application. When you receive an email requesting sensitive information or an email with file attachments, you should communicate with the sender on one of your other communication channels to verify the authenticity of the email or attachment.
Never ask the sender to verify their identity over the same channel as the original communication. If it is a hacker, you’ve just verified to them that they reached their target.
