A scam can look like a text from your bank, a tech support call, a job offer, a held package, an urgent investment, or a warning that your account is blocked.
The story changes. The pressure is often similar: they want you to act quickly, before you check.
In this guide
- Recognize pressure, links, codes, and unusual payments.
- Check through official channels before acting.
- Cut off access and ask for help if you already shared data.
The most important sign: pressure
Be careful when a message or call tries to make you decide right now.
Common phrases:
- “Your account will be blocked.”
- “Final notice.”
- “You have to pay today.”
- “Confirm now.”
- “There is an urgent problem.”
- “Do not hang up.”
Some legitimate alerts are important, but a real organization normally does not need you to hand over passwords, codes, or money through a link that arrived suddenly.
If there is pressure, slow down.
Do not use the link you received
Many scams take you to a website that looks real. It can have a logo, brand colors, convincing text, and polished forms.
Before signing in or paying:
- Do not use the link in the message.
- Open the official app or website yourself.
- Check whether the alert appears inside your account.
- If it is a phone call, hang up and call the official number.
This works for banks, shops, delivery companies, social networks, payment platforms, and public services.
Be careful if someone asks for codes
A very strong sign of a scam is someone asking for:
- SMS code.
- Verification code.
- Password.
- PIN.
- Recovery code.
- Screenshot of a security screen.
Be suspicious of payments that are hard to recover
Many scams push you toward payment methods where recovering money is difficult.
Warning signs:
- Gift cards.
- Cryptocurrency.
- Urgent bank transfers.
- Instant payments to strangers.
- Payment links sent by chat.
- Small “fees” to release a prize or package.
A real offer should not force you to pay in a strange way or under pressure.
If it seems too good, check more
Not every cheap offer is fake. But promises that look too good deserve a pause.
Examples:
- A very expensive product at a ridiculous price.
- An investment with guaranteed returns.
- An easy job with high income from day one.
- A prize draw you do not remember entering.
- A stranger offering money, gifts, or unexpected help.
Look for opinions outside the website offering it, check the domain, see whether there are real contact details, and do not pay in advance if you do not clearly understand who you are paying.
Do not keep the problem secret
Another common sign is being asked not to tell anyone:
- “Do not tell anyone.”
- “This is confidential.”
- “If you warn someone else, you will lose the opportunity.”
Secrecy reduces the chance that someone can help you check. If you have doubts, ask a trusted person before paying, sending data, or installing anything.
If you already clicked or gave data
Do not waste time blaming yourself. Act.
Depending on what happened:
- Change the password for the affected account from the official website or app.
- Turn on two-step verification if it was not active.
- Contact your bank if you shared payment data or made a transfer.
- Review open sessions in the account.
- Save screenshots and messages in case you need to report or dispute it.
- If you installed something, check the device and ask for technical help.
The sooner you cut off access, the better.
If you are in Spain, INCIBE can provide guidance through its cybersecurity helpline, 017, and its website accepts fraud reports. If money was stolen, you were threatened, someone impersonated you, or there was clear harm, consider reporting it to the National Police, Guardia Civil, or the relevant local authority.
Before you move on
You do not need to memorize every scam. Remember the signals: pressure, unexpected links, codes, unusual payments, too-good promises, and secrecy.
If one appears, stop. If several appear, do not continue through that channel.
