The short answer
If you receive an unexpected call regarding crypto investments, verify the caller's identity through official, public channels rather than provided links. Never allow remote access to your device, and do not log in to BankID at a caller's request. Spoofed caller IDs are not proof of authenticity; always exercise extreme caution and hang up if you feel pressured or suspicious about the nature of the investment.
Fraudsters in Sweden frequently use unsolicited calls to target individuals for crypto-related scams. By adopting the persona of a financial advisor or an investment firm representative, they aim to build trust and eventually persuade you to hand over funds or sensitive data.
Understanding thatcaller ID spoofing is a common tool is essential; seeing a familiar number on your phone screen does not guarantee the identity of the person on the other end. Being prepared with a verification strategy can help you identify these attempts early and avoid significant financial harm.
01Verifying Callers Independently
If someone calls you offering investment opportunities, you should never accept their claims at face value. A legitimate firm will have a public, verifiable contact number. Instead of continuing the conversation, hang up and independently look up the company’s official contact information on their own website.
Use the Financial Supervisory Authority (FI) database to check if a firm is registered to provide financial services in Sweden. Absence of a warning from the FI is not a guarantee of legitimacy; it simply means the firm has not yet been flagged by the authority.
- Never trust the caller ID, as it can be spoofed.
- Hang up and find the official phone number online.
- Check the FI's registry for the firm's details.
- Be skeptical of unsolicited offers of profit.

02Warning Signs of Fraudulent Calls
Fraudsters often rely on creating a sense of urgency, such as 'limited-time opportunities' or 'immediate market dips'. They may also claim that your current funds are at risk and need to be moved to a 'secure' wallet.
Another warning sign is a request to use remote access software, which allows the fraudster to view your screen and potentially perform actions on your behalf. Under no circumstances should you grant remote access to an unknown individual, as this provides them with direct access to your personal digital environment.
- Avoid high-pressure tactics or claims of urgency.
- Do not allow remote access to your computer or phone.
- Be wary of requests to move funds to 'secure' wallets.
- Question why an stranger would offer financial advice.

03The Danger of BankID Manipulation
A key part of these scams is tricking the victim into using BankID while on a call. The fraudster may claim this is necessary for 'identity verification' or to 'open an account'. This is a severe risk.
Never use your BankID at the request of someone you did not contact yourself. If you are prompted to sign or log in by a person on the phone, immediately disconnect the call. Legitimate institutions will never ask for this information over the phone.
- Never log in with BankID at a stranger's request.
- Treat BankID as a personal, private document.
- Disconnect the call if pressure is applied to sign something.

04Protecting Yourself Against Scam Calls
If you receive an unexpected visit or call, maintain your boundaries. You are not obligated to listen to the caller's pitch, and you have every right to hang up immediately.
If you are concerned about your security or the identity of a caller, talk to a family member or a trusted individual before taking any action. Often, a second opinion can help you see through a well-crafted ruse.
- Trust your intuition; if it feels wrong, hang up.
- Discuss unexpected investment offers with a trusted friend.
- Recognize that fraudsters are trained to appear trustworthy.

05Practical Decision Checklist
Use this practical checklist for any unsolicited investment offer:
1. Did I search for this investment myself? 2. Is the caller requesting my personal or bank information? 3. Are they trying to guide my mouse or phone screen remotely? 4. Does the opportunity sound 'too good to be true'? 5. Is there pressure to decide right now? If the answer is yes to any of these, disconnect the call immediately.
- Follow the checklist for each unsolicited call.
- Keep the phone number of your local police station ready.
- Prioritize caution over immediate profits.

Questions people ask
Is it safe to talk if the phone says it's from the bank?
No. Caller ID can be faked. If someone calls you claiming to be your bank, hang up and call them back using the official number listed on their website.
What should I do if I already gave them remote access?
Turn off your computer/device immediately, disconnect from the internet, and contact your bank from a different, secure device to block your accounts.
Why do they want me to use BankID?
They want you to authorize a transaction or login that gives them control over your funds or information. Your BankID is your digital signature.
Safety boundaries

- Nobody can promise that funds will be recovered. Treat any guarantee, or any fee demanded to release funds, with suspicion.
- Find official contact details yourself, through the regulator, bank or platform website, not through a message or advert you received.
