Before you click, reply, share, send money, or disclose personal information, verify the source through a route you find independently. A convincing logo, familiar name, professional-looking website, caller ID, or urgent message can all be imitated. The key is to check who is behind the communication and whether its claims hold up—not just whether it looks legitimate.
What to do first when a message or page seems suspicious
Pause before acting
Treat unexpected urgency, threats, prizes, and requests for passwords, verification codes, or money as reasons to stop and check. Don’t click links or open attachments in a suspicious message. If it appears to come from an organization you know, contact that organization using details you find separately. CISA recommends independently contacting an organization when a message claiming to be from it seems suspicious: CISA phishing guidance.
Don’t trust the display name or caller ID
An account name, profile photo, logo, or caller ID can be copied or spoofed. FTC guidance warns that caller ID can be faked, so a familiar number on your screen does not establish who is calling: FTC: How to Avoid a Scam.

How to verify an account or organization
- Inspect the exact web address. Read the full domain rather than relying on a logo, page design, or display name. Watch for misspellings, extra words, or a domain that differs from the organization’s usual address. A polished page is not proof of identity.
- Find a trusted route independently. Type an address you already know, use a saved bookmark, or locate contact details through a trusted source. Don’t use the link or phone number in the questionable message.
- Confirm the specific account or request. Contact the organization through that independent route and ask whether the account, message, payment request, or action is genuinely theirs. If you cannot confirm it, don’t proceed.
- Check the relevant platform’s own signals. Where an account claims to represent an organization or public figure, consult the platform’s current verification and impersonation guidance. Platform badges and policies vary; treat a badge as a signal to assess, not a reason to ignore a suspicious request.
What HTTPS and .gov do—and don’t—tell you
HTTPS encrypts information sent between your browser and a website. It does not certify that the site operator is honest or that the site’s claims are true. CISA recommends HTTPS as an encryption safeguard, not as proof of authenticity: CISA phishing infographic.

A .gov domain has a narrower, meaningful signal in the United States: CISA says only verified federal, state, local, tribal, or territorial government entities can register for it: CISA: Migrate to the .Gov Domain. That rule does not apply to other domain endings, and a .gov address does not guarantee that every statement on a government page is accurate.
How to check whether an article is trustworthy
Check the article’s provenance and evidence, then test its important claims against the material it cites. CISA’s “Question the Source” guidance recommends checking whether an author is identified and assessing the evidence: CISA: Question the Source.

- Author: Is a person or organization responsible for the article named? Can you find information about their relevant expertise or reporting?
- Date: When was it published or updated? An old article may not reflect current rules, events, or product details.
- Evidence: Does the article show where its claims come from, rather than relying on unnamed sources or unsupported assertions?
- Primary material: Follow links to original documents, official announcements, data, or direct statements. Check whether they support the article’s actual claim, not merely a related point.
- Independent confirmation: For consequential claims, look for confirmation from other authoritative sources that are not simply repeating the same original report. If uncertainty remains, ask a knowledgeable person before sharing or acting.
A named author or a link to a source is a useful starting point, not automatic proof. The source itself may be outdated, misrepresented, or too limited to support the conclusion.

What to do if you still can’t verify it
- Do not send money, credentials, verification codes, or personal information based on an unverified message or claim.
- Report suspected phishing or impersonation through the relevant organization’s or platform’s official reporting channel.
- If you shared personal information and are in the United States, the FTC directs identity-theft victims to IdentityTheft.gov for tailored recovery steps. Reporting and recovery options differ by country.
Protect account sign-ins separately
Phishing-resistant sign-in methods can help protect access to your own accounts, but they answer a different question from whether a public account, organization, or article is authentic. CISA describes FIDO-based authentication as resistant to fake-site credential theft: CISA: More Than a Password. A FIDO/WebAuthn security key or passkey does not verify a public profile’s identity or establish that an article is true. Check that your service and devices support the method, and understand the service’s recovery options before relying on it alone.
