The single most effective thing anyone can do to improve their personal cybersecurity is to learn to spot a scam and avoid clicking or responding to it. Scammers rely on trickery, pressure, and urgency to steal money and information. By learning to recognize the warning signs, you become the strongest defense against this kind of fraud.
These terms are just fancy names for three common ways scammers try to fish for your personal information.
The goal of all three is the same: to scare or trick you into taking an immediate, unwise action.
Most scams share a few common traits. If a message or call exhibits any of these, it is likely a scam.
| Red Flag | What to Look For |
|---|---|
| 1. Urgency/Threats | The message warns of an immediate crisis. Examples: "Your account will be suspended in 2 hours," "You owe back taxes and will be arrested," or "Your grandchild is in jail and needs bail money now." |
| 2. Requests for Sensitive Data | You are asked to provide a password, PIN, Social Security Number, or credit card number via email, text, or a suspicious website. No legitimate company asks for a password this way. |
| 3. Request for Unusual Payment | The request is for money to be sent using gift cards (e.g., Apple or Amazon gift cards), wire transfers, or cryptocurrency. Any organization demanding payment with gift cards is a scammer. |
| 4. Poor Quality or Unfamiliar Sender | The email or text contains typos, bad grammar, or uses a slightly incorrect email address (e.g., AmazonService@gmaill.com instead of amazon.com). |
Scams aren't just minor annoyances; they result in huge financial losses every year, especially for older adults who are often targeted due to their accumulated savings and trusting nature.
When you receive a suspicious email, text, or call, follow this simple procedure:
By adopting a skeptical mindset toward unexpected digital communications, you can block the vast majority of scams and keep your personal and financial life secure.
