    Text Message Fraud

    Text Message Fraud is a common technique used by fraudsters in an attempt to obtain your personal banking and card information for the purpose of identity theft or financial gain. The fraudsters send text messages that appear to come from your bank or from legitimate businesses in an attempt to fool you into supplying your personal details.

    These text messages can appear within a genuine thread of messages and will request that you log in to a fake website or call a number.  This type of scam can be referred to as ‘Smishing’.

    • NEVER disclose your Registration Number or Personal Access Code (PAC) or Card information after clicking a link in a text

    • NEVER generate codes from your AIB Card Reader that is requested from a test message.

    • NEVER divulge your One Time Passcode (OTP) for Card transactions.



    If you have received a fraudulent text and disclosed any information, please contact us immediately.

    NOTE:  AIB may on occasion, send you product related or marketing surveys via SMS. It is important to note that these text messages will never ask you for Internet Banking log in details or personal information.

    Investment Fraud/Binary Options

    Investment Fraud is one way criminals can steal your money. They try to convince you to invest in a scheme, shares or commodities, which either don’t exist, or aren’t worth the money paid for them. These scams are common and are usually perpetrated through aggressive sales tactics.  They’re well organised and very convincing. Scammers will target anyone who responds to them and build trusting relationships with their victims over a period of time. Unfortunately, many of these scams are successful. There are many types of scams fraudsters use to persuade you to part with your money.


    If somebody contacts you out of the blue by phone offering you the opportunity to invest in shares that are about to go through the roof - hang up immediately.  Do not respond to unexpected emails or click on adverts across social media or online. The criminals may have researched you and appear to know a lot about you. These criminals will do their homework and make it their business to know as much about you as possible before they contact you. They will give you details that you think only a genuine investment company would know, such as a previous investment or share information. Watch out for offers endorsed by celebrities, these endorsements are totally false.  Be cautious where the rate of return is very high and often advertised as guaranteed or risk-free.


    These criminals will attempt to build a relationship over time. And watch out! An initial small investment may actually produce some returns before you are encouraged to invest a larger amount. If you are contacted by someone claiming to be from a well-known company, check them out independently with the company, look up the company on Google and ring the contact details on the website, not the number you have been given by the caller.


    The caller may ask you to download software to your PC which will provide them unlimited access along with the ability take control of your PC and manipulate the images you are being shown on screen. They will say they are helping you to make a payment and will ask for login information to your AIB online banking along with security codes from your card reader/Digipass. Others will request payments to be made via Debit/Credit card. Never provide one time pass codes received via SMS. NEVER give codes from your card reader/Digipass on foot of a phone call. Never provide login or card information on foot of a phone call. Some of the scams ask you to buy Bitcoin or a cryptocurrency to invest in the scheme. They will set up accounts for you within these companies. Do not provide photo ID, Proof of address without verifying the legitimacy of the caller.


    Remember: If it sounds too good to be true, it certainly is! 


    Always remember: 

    • Check if the company is authorised (by a financial regulator) to deal in such investments

    • Get Independent advice from a qualified financial advisor

    • Report any unsolicited contacts to An Garda Síochána / Police

    • Reject cold calls. If you have been cold-called about an investment opportunity, it is very likely that it is a high risk investment or SCAM

    • Do not respond to high pressure tactics

    • Do not divulge any of your personal or banking information prior to verifying the caller independently. If you have provided any information contact us immediately

    • Persistent emails can be marked as spam and block unwanted emails


    If your investment turns out to be fraud, it is very unlikely that AIB will be able to recoup the funds.

    If you suspect any fraudulent activity from any call you receive, you should end the call and verify the identity of the caller using a known number.


    If you believe that your bank details have been compromised, call the number on the back of your credit or debit card or alternatively call the official number for the branch on the AIB website.

    • Assist them with claiming a tax rebate

    • That you have unauthorised transactions on your Card or Account

    NEVER disclose codes from your AIB Card Reader over the phone.


    NEVER disclose the full five digits of your Personal Access Code (PAC).


    If you have received such a call and disclosed any of your Banking details please contact us immediately

    Email Scams

    This type of fraud is on the increase and it's important that you take the necessary steps to protect your money. Criminals are sending emails in an attempt to trick you in to transferring money to them.


    These types of scams are referred to as ‘Phishing’.


    Emails can claim to be from your Supplier, Contractor, and Solicitor etc. advising of their bank account details or that they have changed their bank account details. These emails will request that all current and future payments should be made to a new account, which actually belongs to the criminal.


    You should not accept any financial instructions via email. You should always VERIFY ACCOUNT NUMBERS on a known contact number. Do not reply to the email or use a contact number contained in the email.


    If you make and authorise a payment to one of these fraudulent accounts, it is highly unlikely that AIB will be able to get your money back for you.

    Purchase Scams – Buying online

    When shopping online, you need to be aware that some of these companies are not legitimate. Fraudsters can spoof/clone a genuine website. They advertise using images of genuine products but at a cheaper price. The goods are never actually available for sale. These cloned sites often have contact details via email only. Phone lines won’t be answered but will be followed up with a call from a private number. These fraudsters will tell you they can only accept a transfer via your bank transfer.


    Examples of products that fraudsters are ‘selling’ include machinery, motor homes and boats.


    Ensure you buy goods and equipment from reputable retailers and sellers.


    Before making a payment ensure you have researched the validity of the company.


    Ask yourself ‘How do I know this person/company is genuine?’.  If the price or description of the product sounds too good to be true, it probably is.

    Malware (Trojans and Viruses)

    Malware is short for ‘malicious software’. The effects of malware can vary widely depending on what it is designed to do.  Some cause little or no damage, while others can be very dangerous and deliberately target customers who bank online.


    Banking specific malware can gather personal or security information entered on the infected PC/laptop/phone. Such malware can gain access to the device when the user is tricked into opening or running an infected attachment they have received from a seemingly legitimate mail, through an infected file they have downloaded or even by visiting an infected website.


    How you can identify Malware threats or fraudulent attempts to obtain personal details while banking online?

    The signs to look for include:

    • Pop-up windows on Internet Banking asking you to key details into your Internet Banking Card Reader, and

    • Requests on Internet Banking to confirm your identity with your credit/debit card details (see the sample screen shot below)

    Advanced Fee (419) Fraud

    Advance fee fraud or ’The 419 (four-one-nine) fraud’ as it's also known, is a method by which a fraudster attempts to trick you into supplying 'up-front' money to secure your involvement in their specified transaction. There are many variations of this type of fraud.


    How does Advanced-Fee (419) Fraud work?

    • You would first receive an unsolicited communication (e.g. fax, email, letter or website) concerning an individual, business or government entity wanting to get money out of the country

    • These communications (e.g. websites, letters, emails or faxes) often look very similar to those of a reputable institution

    • The fraudster then contacts you directly offering to transfer money into your bank account in exchange for a small fee

    • If you respond to the initial offer, you may receive ‘official looking’ documents to complete.

    • Typically, you are then asked to provide a blank letterhead and your bank account details, in addition to money to cover the transaction, transfer costs and attorney's fees

    • The fraudster will then quickly move your money to an offshore account and then move on to their next victim.


    How to recognise Advanced-Fee (419) Fraud letters

    • They generally include requests for ‘up-front’ money to secure your involvement in their transaction. Hence the name: ‘advanced fee fraud’

    • They are generally marked ‘urgent’ or ‘confidential’

    • They often promise millions of dollars for your help, once the transaction is completed

    • They always have a scheme or a reason for contacting you, examples include:

            - An inheritance that is tied-up

            - Diamonds in boxes that they need to get out of the country

            - Millions of dollars in boxes that they need to get out of the country

            - Money ‘frozen’ by government

            - Excess oil or other merchandise

    • Most 419-fraudsters present themselves as individuals such as doctors, lawyers, sons of ex-generals and other important persons, to trick you into thinking they are respectable and trustworthy individuals

    • They are always seeking a foreign ’partner’ to help them

    • They will ask for personal information about you, such as:

            - Personal or Business letterhead

            - Banking information

            - Personal telephone number.


    What should you do if you suspect a 419 scam?

    Delete the email, destroy the letter or fax. Although they may look like it is addressed specifically to you, they will have been sent to many people.

    SIM Swap Fraud

    What is SIM Swap Fraud?


    The objective of these fraudulent SIM swaps is mainly to intercept messages sent by SMS for banking transactions over the Internet.


    Fraudulent SIM swap is a mobile device specific fraud where the fraudster approaches your mobile service provider pretending to be you and requests that the existing mobile number be assigned to a new or ’replacement’ SIM card. Once the SIM swap request has been processed, the fraudster is able to access the new SIM card and may divert calls and receive your SMS notifications. With texts and calls now routed to the ‘new’ SIM card, the fraudster is able to access any unique codes sent by the bank to access people’s bank account. This scam will be used in conjunction with other Common Frauds and Threats such as a Phishing or Vishing attack’s as described above.


    To safeguard against SIM swap fraud, we suggest that you follow these simple steps to help stay secure:


    • Never disclose any sensitive or personal information such as log in details, bank details, passwords or passcodes to any source

    • Never ignore an SMS message alerting you to a pending SIM swap request on your account or if you suddenly cannot make or receive calls or messages. Contact your mobile provider immediately and enquire whether a SIM swap has been processed on your number

    • Protect your mobile device via password (use strong passwords that would not be easy to guess) or biometric security (fingerprint). Where possible, set the screen auto-lock timer to activate after just a few minutes of inactivity

    • Disable automatic connections. Some devices automatically allow connections to available Wi-Fi networks, and Bluetooth devices may connect and transmit data without your knowledge

    • Consider using your manufacturer’s applications which allow you to find and track your device if lost. These applications also give you the option of locking or wiping your phone remotely if required

    • Do not open emails from unknown sources – even if these appear legitimate or authentic and seem to come from your banking institution

    • Never follow a link provided to you in an email to access the Internet Banking site for your banking institution. Instead physically type the address into the browser address bar.



     If you suspect that you have been a victim of SIM swap fraud, contact your mobile provider immediately.
