Be vigilant!


  • Beware of criminals who impersonate bank employees, investment brokers, customer service staff or even police officers. Be vigilant when someone on the phone asks you for personal details, passwords or offers to install an unknown app.

    1) You get a call from someone claiming to work for a bank and saying, for example, that someone tried to log into your account or wanted to take out a loan using your details.

    2) They persuade you to install a customer service application (e.g. TeamViewer, QuickSupport, AnyDesk), which actually allows them to control your device remotely.

    3) They may also ask for your login details, full card details or BLIK code, and persuade you to make transfers or BLIK transactions.

    Be careful! In such a situation, don't give out any personal details, don't install any apps and don't perform transactions at the caller's command. Hang up and call the official number of the company or institution concerned, provided on the official website.


    Our employee on the phone can send you your details in the mobile app.

    Keep in mind! You will only receive a notification confirming your details in the banking app. Bank employees do not send links or business cards via chats, messengers or SMS messages.


    You can also easily confirm your identity in the app without giving your details over the phone. During the call, our employee will send you a notification in the banking app. Read it carefully and confirm it. You do not need to provide any personal information in this situation.

    Keep in mind! Our employee never asks you for your password or PIN!



  • Fraudsters are taking advantage of our emotions and eagerness to help those affected by the floods. It is more and more common now to come across a fake message that is not aimed at supporting, but at phishing for your money or data.

    • Fake fundraisers. Support only organisations that you know. You can also use a ready-made charity transfer in your app. You can find it in the bottom menu under Payments > Transfers. Information on legitimate collections is posted on the website of the Public Collections Portal of the Ministry of the Interior and Administration.
    • Fake RCB alerts with links. Don't click on the links. Real alerts do not contain them.
    • Social media posts. Watch out for posts with drastic messages about the floods. Often their purpose is not only to create chaos, but also to phish for data. If, when you click, you are asked to enter your login details, don't do it - the scammer is trying to take over your profile in this way.


  • Scammers trying to get into your computer have a new way of doing it. This time they use the CAPTCHA mechanism - a short test that is used on some websites to confirm that the user is not a robot.

    A correct CAPTCHA requires, for example, entering some letters or indicating certain objects in a picture.

    The criminals have adapted this scheme, but they provide on-screen steps for the user to follow. These steps are altered compared to the standard CAPTCHA. If you follow the instructions and click the sequence, you open access to your device to the hacker. Your computer will download and install the malware.


    If you follow the instructions and end up installing malware, the fraudster can:

    • get your passwords stored on disk and in cookies
    • take over your social network accounts
    • encrypt or destroy files on your device
    • take over your account credentials and this way steal your money or even your identity

    First of all, be vigilant! The legitimate CAPTCHA can take many forms, but it will never require you to use the WIN (Windows button) + R key combination.

Scammers' schemes

  1. Phishing
  2. Fake consultant
  3. Malware
  4. Card frauds
  5. Message from "a friend"
  6. Fake stores and ads
  7. Cryptocurrency frauds
  8. SIM card swap
  1. What is phishing?

    It's an attempt to catch you in scammers' nets, who e.g. impersonate your bank.

    What for? To make you pass your personal data, login or payment card details. As a result, your account or card will be accessed by unauthorized persons who can order transactions or impersonate you.

    But how? The scammers send e-mails or SMS-s persuading to act immediately, such as:

    • 'Your bank account has been blocked'
    • 'Pay fee for your card'
    • 'Your parcel has been withheld due to underpayment, settle the arrears'
    • 'On ... the execution was initiated. Possibility of amicable repayment for PLN 8.44'

    Be careful

    • Do not click on links and do not download any applications unless you know the sender of the message.
    • You will never receive such a message from Bank Millennium, because we do not send any links in e-mails or SMS.
    • When you log in on the bank’s website, look at the address bar. Check if the website address is right, there are no typos or misspellings and if the connection is encrypted (icon with a closed padlock).
    • If something looks different than usual, please do not log in - we always inform about it when we change something on the login page.
    • On the login page, we always ask for only two randomly selected characters of the identifier - never enter the entire PESEL number or the entire document number.
  2. Fake consultant, or vishing

    How do you know that the person you are talking to on the phone is really who they say they are? This is obviously very difficult, and it is easy for fraudsters to gain our trust and obtain sensitive data.

    How to defend yourself?

    • Don't share login details with anyone - only you should know them.
    • The bank consultant can ask you to provide MilleCode, but will never ask for your login password.
  3. Malicious software, or malware

    How does it work? You get an e-mail or an SMS with a link to download an app or 'very important' attachment. You click on it and this way you infect your computer, phone or tablet.

    What for? This one click allows to install a malicious application or program on your device that can, for example, track your activity and download data, or take control of your device completely.

    Keep in mind:

    • never click on unknown links
    • don't download attachments if you don't know what's in them or you don't know the sender of the message
    • do not install unchecked applications - preferably before installing an application, look for comments about it in the application store
  4. Card frauds

    How? You enter your card details in an unchecked store, or in response to fake e-mail, you give someone your plastic card or write your PIN on the card or a sticky note attached to the card.

    What for? The fraudster needs your card details to make online transactions or tokenize the card, for example in Google Pay service. To pay in a stationary store the fraudster needs your card, and for larger payments also PIN.

    How to defend yourself?

    • Never scan the card, do not pass on the data from the card to anyone
    • Pay with your card in trusted online stores
    • Carefully read the terms and conditions of internet subscriptions you accept (sometimes the first month is free, and the next one is charged a high fee)
    • Do not give your card or PIN to an unauthorized person (e.g. waiter in a restaurant or bar
  5. Message from "a friend"

    Your friend informs you via messenger app that he need money at once, he will return tomorrow and you only need to give him a BLIK code. Or he sends you link to the transfer (PayByLink).

    What do you do? At first, everyone is probably willing to help their friend. Yet, be careful! This may be a fraud scheme. Before you help your friend, make sure It really is your friend - scammers could have get access to his account. The best you can do is to call him and ask if he really is in need.

  6. Fake stores and ads

    How does it work? Scammers publish fake ads and fake stores' websites. Very often they give "special offers" or even rewards to get your attention and persuade you to use their offer.

    Don't get yourself "caught":

    • Before taking advantage of such a "great deal", try to verify that it is trustworthy.
    • You can search for comments on the Internet about a given company or a specific website.
    • If you have any doubts, do not order a payment or share your details.
  7. Fraud on cryptocurrency exchanges

    How? You come across an ad promoting easy ways to invest in cryptocurrencies:

    • "You don't need to know anything about investing"
    • "We guarantee quick profit"
    • "We will do everything on your behalf, only scan your payment card/ID and give us your login details/SMS P@ssword"

    What for? To extort your personal details, login details to your bank account or payment card details, and above all, to persuade you to transfer your money. Unfortunately, when you want to withdraw your funds, contact with the "broker" is broken and the money transferred cannot be recovered.

    How to defend yourself?

    • Check the credibility of the broker. Check online reviews, for example in conjunction with the words "fraud" or "scam". Don't stop at just one review page.
    • Check, if the institution - "broker" is on the KNF's list of warningslink opens in a new window
    • Do not share your bank account login details with anyone.
    • Do not share confidential information about your payment cards with anyone.
    • Do not send photos/scans of your ID to anyone.
    • Do not install suspicious software on devices from which you log into your bank account.
    • If you receive a transfer from an unknown sender, do not forward the funds under any circumstances, even if "your Advisor" asks for it - you may unknowingly be involved in a crime.

    More information on both investing in cryptocurrencies and the resulting threats can be found at: KNFlink opens in a new window, NBPlink opens in a new window (in Polish) and ZBPlink opens in a new window (in Polish).

  8. SIM card swap

    How? The scammer goes to the mobile phone salon claiming to be you and asks for SIM card replacement. The operator blocks the old SIM card and gives the fraudster a duplicate.

    What for? To take control of the authorization of your transactions.

    When you should realize that you are a fraud victim?

    When you want to use your phone, for example call someone, and it is impossible.
    If such a thing has happened to you, be sure to report it to your mobile operator and check your account.
