What is phishing?

Phishing attacks are fraudulent emails or websites designed to trick users into sharing sensitive information. Phishing may be used in conjunction with vishing (phone fraud) or smishing (sms fraud) where criminals will follow up via very convincing phone calls or text messages. Criminals may already have some of your personal data and could exploit this knowledge by presenting it to you as a means to establish credibility. This is a deceptive ploy to trick you into revealing more information, enabling them to carry out their manipulative tactics.   

How does phishing work?

• You will receive an email pretending to be form a legitimate source e.g. your Bank, Telephone company, Revenue or other reputable company.
• The email may contain a link or attachment requesting you to click on the link or download the attachment to complete a specific action such as “re-activate your account”, “update your security details” etc.
• Once you have taken this action you may be brought to a fake website where you are required to input a range of personal and security details e.g. Internet Banking details, your password or your personal access number etc.
• Once the details are given away the criminal has your Internet Banking details and can log into your internet Banking as you and transfer funds from your account.
• This fraud may be used in conjunction with Vishing or Smishing (see Telephone frauds). Where criminals will follow up with a phone call. As they may already have some of the information you have just provided they may seem convincing.

1. Don’t respond: Never reply to any email asking for financial, personal or security information unless you independently verify that the email came from the company it claims to be from.
2. Security details: Never give away security details, such as your PIN or full online banking password to anyone.
3. Links and Attachments: Never click on a link or attachment in an email until you have verified it is from the source it says it is from.

How can I protect myself online?

Using up-to-date good quality internet security software is a must but you should also protect yourself in other ways:

Your Banking

• Free Wi-Fi is readily available but it may not be secure even when it requires a password. If you use public Wi-Fi you are risking your online identity and your banking details.
• Keep a record of all your online transactions.
• Make sure that you conduct your financial transactions only on a secure web page using encryption. Look for a closed padlock in the status bar, and see that the URL starts with a “https” instead of just “http”.
• Change passwords regularly– we recommend that you use a separate email address and device for your banking needs.
• Be aware of unsolicited emails asking for bank card or PIN numbers and never divulge this information.
• Be aware of phoney emails/websites that try to trick you into giving personal information including mobile telephone numbers, mother’s maiden name and date of birth etc. Try to use a known web address.
• Never send money to or share the details of a money transfer with someone that you do not know.
• Where a site shows the last time that you logged in, always check that this reflects the last time you accessed the website.
• Always type in the web address www.open24.ie and login to your internet Banking from there.
• Avoid saving links to your favourites or clicking on non-PTSB sites or emails as they may be compromised by fraudsters and bring you to a fraudulent website.

Important Information: Remember, PTSB will never call, email or text you asking for: your account details, your Open24 number, Internet Password, Personal Access Number (PAN), your Visa Card CVV number or One Time Passcode. If you ever get an unsolicited phone call, email, text message or pop-up asking for any of these please contact us on 0818­ 50­ 24­ 24 or +353­ 1­ 212­ 4101.

Emails and texts requesting information

• Be skeptical – It’s better to err on the side of caution. Unless you are 100% sure that a particular message is genuine, assume it is not.
• Check the email address. Is it the same as the email address you usually receive emails from, or is it just similar?
• If you receive a notification from your bank (SMS/In App message) with a passcode required to complete an action or transaction please ensure that you fully read and understand the message before using the code provided.
• Be careful if there is an urgent call to action in the e-mail such as ”Security Alert”, “Your account has been blocked”, “If you don’t respond your account will be closed”. Criminals want you to act quickly and without taking due care.
• Do not click on links, download files or open attachments in an e-mail unless you are sure of its authenticity.
• Only open an attachment when you are expecting one, when you know what they contain and you are confident it is from a genuine source.
• If you are unsure, pick up the phone, call a secure number from a legitimate source and validate the message. Remember, a genuine individual/company may have had their e-mail compromised.
• If your browser has a pop-up blocker, you should use it.
• Do not copy any website addresses from a pop-up window into your browser, as a legitimate company will not ask you for your information in a pop-up window.
