Phishing Guidance

What is Phishing?

More than 90% of cyber attacks begin with phishing according to the Cybersecurity and Infrastructure Security Agency (CISA). Anyone can be a victim.

Phishing is the attempt to steal information by pretending to be someone you know and trust. The attacker on the other end is after your information (password or credit card #), or trying to install malicious software such as ransomware, remotely access trojans (RATs), viruses, etc. to gain access to your organization's network.

Always check the sender's address and hover over links before clicking. Never send sensitive personal information in an email (e.g., passwords, social security numbers, credit card numbers). And most importantly, SLOW DOWN and consider if the email makes sense.

Here are some common phishing techniques:

Spear PhishingSmishingVishing
Email phishing that targets specific individuals or job titles. Hackers research the target to make the attack more personalized and increase chances of success.Phishing conducted via text message. A smishing text, for example, attempts to entice a victim into revealing personal information via a link that leads to a phishing website.An attacker calls the user and asks the user to dial a number. The purpose is to get personal information through the phone. Vishing is mostly done with a fake caller ID.

There is no single red flag that guarantees an email is phishing or legitimate. For example, not every email from an external sender is bad, nor is every email from an internal address good. But in general, here are some signs that should tell you to slow down and consider things more closely:
