How to Detect Online Scams
Practical, no-nonsense ways to spot a scam before it costs you money or your personal information — plus how to use the free NetArmature extension to check any link in seconds.
How to spot a scam website
Scam sites are built to look legitimate in seconds, but a few checks usually give them away.
- The domain was registered very recently, or it's a slight misspelling of a brand you know.
- It's hosted on a free platform, a link shortener, or a dynamic DNS service — unusual for a real business.
- It creates urgency: countdowns, "last chance," or pressure to act before you can think it through.
- It asks for payment, gift cards, or crypto through channels a legitimate company would never use.
Check a suspicious link with NetArmature — it checks these signals automatically. For a deeper dive, see our fake website checker guide.
How to check a suspicious link
Before you click a link from an email, text, or social media message:
- Hover over the link (or long-press on mobile) to preview the real destination before tapping it.
- Watch for redirect chains that hop through several unrelated domains before landing.
- Be extra cautious with shortened links (bit.ly and similar) — they hide the real destination.
- When unsure, paste it into NetArmature's scam checker instead of opening it directly. See our suspicious link checker guide for more.
How to identify a fake job offer
Job scams have surged with remote work. Common warning signs (see our full job scam detector guide for more):
- You're offered the job with no interview, or after a suspiciously short one.
- You're asked to pay upfront for training, equipment, or a background check.
- You're asked to buy gift cards, forward money, or receive/re-send funds through your own account.
- The recruiter only communicates over chat apps and avoids a verifiable company email.
How to spot a rental scam
Rental scams target people searching for housing under time pressure (see our full rental scam detector guide). Watch for:
- A price that's noticeably below similar listings in the same area.
- The "landlord" claims to be out of the country and can't show the property in person.
- You're asked to wire a deposit or first month's rent before signing a lease or seeing the unit.
- The listing photos appear on other websites under a different address or contact.
How phishing scams work
Phishing tries to trick you into handing over credentials or payment details by impersonating a brand, bank, or service you trust. See our full phishing detector guide for more.
- The message creates urgency ("your account will be suspended") to stop you from checking carefully.
- The sender address or link domain is a close but not exact match for the real brand.
- It asks you to "verify" or "confirm" a password, card number, or one-time code.
- Legitimate companies won't ask for your password or a full card number by email, text, or chat.
What to do if you already sent money
If you think you've been scammed, acting fast matters more than feeling embarrassed — scammers count on people staying quiet.
- Contact your bank or card issuer immediately to report the charge and ask about a chargeback or reversal.
- If you shared passwords, change them immediately — starting with your email and financial accounts.
- Report the scam to your local consumer-protection agency and, if applicable, the platform it happened on.
- Save every message, receipt, and link involved — it helps investigators and other victims.
