Identity theft, a term only in use a few years, is much more widespread than any of us would like to think.

It occurs when a criminal transfers or uses a person's identity illegally, generally in order to gain access to the victim’s finances, or to use their identity to set up a bogus bank account.

Even worse are the criminals involved in organised crime, who aim to use your identity and money for illegal activities such as drug and people trafficking. John Lowe of MoneyDoctors.ie investigates.

We have come a long way in the last few years, technology wise. As we all know, the internet can be both a blessing and a curse, and while many scams these days manage to succeed due to the online and social media, internet access also means that such identity fraud is a lot more publicised and people are becoming educated on the risks as a result.

The most common forms of fraud to watch out for in Ireland today are:

1. Phishing

Perhaps the most widespread and convincing of all, this scam takes place via email and often involves receipt of a mail that appears to be from a reputable business, perhaps one with which you already engage. However, clicking any link within the email results in damaging software, or malware, being downloaded to your computer.

Another form of phishing involves the victim being told they have won a prize and convinced to supply their bank details to the scammer in order to collect it, or that they have been contacted by a rich foreign diplomat or prince who needs help moving some money around and just needs a friendly bank account in which to rest his funds for a while – a service for which he’ll pay you handsomely...

Safeguard: The general rule to avoid falling victim to phishing is not to trust emails that appear to be from a bank - double check with your own bank if unsure - and to never click a link within a suspicious email.

2. Card fraud

Stolen or copied credit/debit cards, or their details, are used to withdraw cash or to make purchases online. Your card details can be harvested through "skimming", a process whereby a device fitted to an ATM copies the details of your card as you insert it.

Safeguard: Do not use any ATM that looks suspicious or as though it has been tampered with.

3. Invoice redirection fraud

Criminals contact a business pretending to be, for example, a supplier with whom that business already works, providing alternate payment details so that the funds for any future purchases from that supplier are paid to the scammer.

Safeguard: Should this happen, always end the call and phone back your supplier directly.

4. CEO fraud

Junior finance employees are contacted by someone purporting to be a senior member of staff at their company, requesting that a work-related payment be made urgently – to the scammer’s account.

Safeguard: Use your common sense. First, check that the email address is definitely an internal company address. If you are suspicious, speak to a trusted member of staff directly.

5. Phone fraud

Another particularly common scam, this occurs when a person receives a phonecall or text from someone purporting to be, for example, a bank or service provider. The scammer will often ask for ID details, like passwords and account numbers.

Safeguard: Never, ever give out your password or bank details on a call like this.

6. Advance fee fraud

This occurs when people are convinced to pay upfront for a product or service that does not exist, such as a rental down payment for a property they have not seen in person.

Safeguard: Try to be wise. If something seems too good to be true, trust that it probably is; and if you have never seen something, don’t throw your money at it.

7. Romance fraud

Often linked to "catfishing" – where a person is led to believe that they are talking to someone online, when that online friend does not in fact exist – romance fraud occurs when someone believes they are in a romantic relationship with a person they have met online, only to be asked to pay for the person to visit them, or to help the person out in some financial way.

Safeguard: Be careful about who you speak to, and never send money to a person you have never met.

It’s not just nameless, faceless, online entities, either: as of August this year, 171 suspected cases of fraud had been detected in registrations for the public services card, with duplicate applications being made to the Department of Employment Affairs and Social Protection.

What should I do if I’ve been a victim of fraud?

If your cards are involved, or could be involved, immediately contact your bank and ask them to freeze them, then contact your local Garda station.

But prevention is better than cure; and by adopting a few simple rules, you can arm yourself against fraudsters heading your way especially at Christmas time, a vulnerable season.

1. Watch out for "shoulder surfers" and "skimmers"

Shield the entry of PINs and be aware of people standing too close to you when you are using your credit or debit card in public. Many criminals use mobile phone videos and cameras when shoulder surfing to obtain your private information; so if you feel someone taking a peek, don’t be too embarrassed to cover the keypad with your hands.

Never allow a salesperson to take your credit card out of your sight when you are making a purchase. It is also advisable to use ATMs that are familiar to you, so it is easier to notice if the equipment has been tampered. Your increased awareness may reveal a skimmer’s attempt to steal PINs and banking details at that site.

2. Online safety

Do not click on links in any emails you receive from financial institutions even if you are 100% sure they are legitimate. Go to your browser instead and type in the domain name of the institution, for example www.aib.ie or www.paypal.com, before logging in to your account.

Remember, some emails you receive about your financial accounts are "phishing" emails.

3: Shop safely

Use a "virtual" card number. These are randomly generated credit card numbers that are disposable and that online shoppers use once and throw away. It’s linked directly to your real credit card account so purchases show up on your monthly bill. The service is free and easy to use.

AIB has a product called Code Card, a wallet-sized card with 100 temporary numeric passwords on it, designed to be used each time you want to make one-off transfers or set up new accounts. Each password is single use and unique. Ulster Bank offers a similar service.

4. Shred bebfore dumping

Do not throw pre-approved credit offers in your recycling without shredding them beforehand. Fraudsters can sift through bins to retrieve these and use the offers to order credit cards in your name. Other sensitive information like credit card receipts and all unneeded bills should be destroyed as well.

5. Get the hammer out

Consider using a software tool, such as DBan or Eraser, to do a complete wipe of your drive; but beware that erasing data does not eliminate the original bits and bytes. Physically remove the hard-drive from any computer or table you no longer want and smash it with a hammer to ensure you’re not passing along your personal details. Thieves are very sophisticated today and can easily recover data from an erased or damaged drive.

6. Be a prudent poster

Posting just a handful of personal details on a website can give fraudsters all the information they need. Armed with info found on your Facebook, Instagram or Twitter accounts, they can open bank accounts and credit cards in your name. It is possible to protect your privacy by adjusting your settings.

Take my advice and you will live a lot more safely online. Trust me – your bank balance will thank you for it.
