Don’t fall for online scams

Criminals have devised a number of scams for obtaining customers’ banking information and stealing their money. These scams are well honed and well practiced, and planned down to the last detail. Criminals usually start by pretending to be a legitimate contact, such as a tech support employee, someone wanting to buy or sell an item online, or even a bank advisor.

Below are some examples of common scams, so that you can learn to identify them and spot risky situations.
Always proceed very carefully when you’re contacted by someone you don’t know or receive a message out of the blue.
 

 

In this kind of scam, a criminal pretending to be from tech support instructs you to install software on your computer. They then use the software to take over your computer and steal your bank account data, and eventually make fraudulent payments.
 

  • You receive a phone call from someone claiming to work for a tech support company. This person (in reality, a criminal) tells you your computer has been hacked and infected with a virus.
  • Or perhaps your computer suddenly freezes and the number of a tech support company appears on the screen.
  • The criminal on the phone asks you to install software so that they can take over your computer and remove the virus.
  • Then, with the excuse of needing to run tests or enable you to pay for the service, the criminal asks you to provide your credit or debit card details or log into your online banking system.
  • This gives the criminal your banking information, which they use to make fraudulent payments.
     

Never give out your login details or card numbers.

Remember that BCV will never ask you for your security codes or payment card numbers.

Never log into your online banking system when somebody else has control of your computer.

Watch out if someone:

  • tries to worry or scare you into doing something
  • pushes you to act in a hurry
  • asks you to install software on your computer
  • asks for your login details
  • asks you to approve an online banking transaction
  • asks you to provide a code sent by text message or to scan a QR code
  • asks you to log into your online banking system.
     

 

Another way criminals try to get your banking information (like your credit card number) is to send out fake emails and text messages. These messages could also direct you to a fake website that looks almost exactly like your bank’s website.  

  • You receive an email or text message that appears to come from your bank, since it contains your bank’s name, logo, and colors.
  • The message asks you to provide confidential banking information – your credit card number or login details, for example – for some made-up reason (such as a system upgrade or to update your file).
  • The criminal who sent the message uses this information to make fraudulent payments.
  • Or perhaps the message asks you to log into your online banking system via a link in the message. This link directs you to a fake website resembling that of your bank.
  • When you enter your login details into this website, the criminal records the information and uses it make fraudulent payments.
     

Always type your bank’s URL address manually into your browser (www.bcv.ch for BCV).

Delete suspicious emails.

If you’re not sure whether an email appearing to be from your bank is authentic, contact the bank directly.

Never give your login details or card numbers to a third party.

Watch out if someone:

  • tries to worry or scare you into doing something
  • pushes you to act in a hurry
  • asks for your login details, security codes, or card numbers
  • asks you to approve an online banking transaction
  • asks you to provide a code sent by text message or to scan a QR code
  • asks you to log into your online banking system

 

This scam targets people who want to buy or sell something on an online marketplace. A criminal contacts a prospective buyer or seller and asks them to provide their banking information, ostensibly to complete the transaction.

  • Suppose you’ve put an item up for sale on an online marketplace such as Facebook Marketplace, Anibis, or Ricardo.
  • You’re contacted by someone who would like to purchase the item and pay for it through a money transfer service (PayPal or Western Union, for example).
  • The individual (in reality, a criminal) sends you a link where you can sign up for the transfer service and provide your confidential banking information, such as your online banking password or credit card number.
  • Then, in order to “complete the transaction,” the criminal sends you a QR code to scan with your mobile banking app. This opens an online banking session without your knowledge, which the criminal uses to make fraudulent payments.
     

Never give your login details or card numbers to a third party.

Never use your mobile banking app to scan a QR code sent by a third party.

Exchange items in person whenever possible.
 

Watch out if someone:

  • insists that payments are made through a money transfer service like PayPal, MoneyGram, Western Union, or Wise
  • says they can’t meet in person to exchange the item
  • asks for your online banking information or card number even though you’re the one selling the item
  • wants to buy the item from you, but is located in another country.
     

 

Online marketplaces are increasingly popular options for selling second-hand goods like children’s clothing, furniture, and concert tickets. Unfortunately, criminals are highly active on these websites and use fake accounts to trick users out of their money. You’ve got to be very careful when using these websites and keep your eye out for fake accounts.

If you’re using Facebook Marketplace, check whether the individual’s or company’s profile has been verified (look for the blue verification badge).

Also check the profile details – name, picture, when it was created, content (followers and posts), and the associated URL address.

If the individual or company has an account on another social network (such as X or Instagram), compare the profile details and especially the bio, or look up the individual or company on Google.
 

  • The name in the associated URL address doesn’t match the one on the profile page.
  • The account name is very short, such as a first name followed by a series of numbers.
  • The profile was created a short time ago and there’s no picture (or only a very recent one).
  • The account has very few followers, and they’re spread out in different countries.
  • There are very few posts on the account and the timeline is very recent.
  • The person who wants to buy or sell something is located in a different country.
  • Messages written by the person contain a lot of spelling and/or grammar mistakes.

  • Always type in BCV’s URL address manually (www.bcv.ch ).
  • Do not use public computers, such as those available for guests at hotels.

Look for the following features:

  • A lock icon in the address bar
  • BCV’s name, which will appear either next to the lock icon or in the window that opens when you click on the icon (“Certificate issued for…”).

 

Stay secure when you use the BCV Mobile app on your smartphone

  • Download the app only from official stores.
  • Regularly update the app and your smartphone’s operating system.
  • Lock your smartphone with a PIN or facial or fingertip recognition.

Be careful when purchasing items on an online marketplace

  • Never scan QR codes sent by users you haven’t verified.
  • Never use the five-digit payment codes sent by sellers on these marketplaces (Facebook Marketplace, Anibis, etc.).

Keep your eyes peeled when sending and receiving money

  • Never approve a payment to someone you don’t know.
  • Don’t accept a payment request unless you’re specifically expecting one.
  • If you’re not sure you have the right phone number for a beneficiary, ask the beneficiary to send you a payment request (as opposed to you initiating the payment directly).
  • That way, you can be sure you send the money to the right person.
