To check if your card details are leaked, use reputable data breach checker sites like Have I Been Pwned, monitor your bank statements for unauthorized transactions, and watch for unusual mail or debt collector calls; if you suspect a leak, contact your bank and credit bureaus immediately, enable multi-factor authentication, and change passwords, say Cyber.gov.au and Moneysmart.gov.au.
Check your bank account
Log in to online banking and check you recognise all payments. If any seem unfamiliar, or you think someone might have unauthorised access to your account, contact your bank. Also, ask them to set up any alert features they offer.
Sign up for breach alerts
Some breach-check or password managers offer breach monitoring. Breach monitoring lets you know if your information has appeared in a new leak. You can add alerts for each email address you use online. This helps you act fast to secure your accounts.
Warning Signs
Fraudsters might get your card details by: Tricking you into entering your details on a fake website. Intercepting your information when you're shopping online. Cloning your card using a modified card reader.
Phishing. One of the most common ways cybercriminals steal credit card information is through phishing attacks. Phishing occurs when a cybercriminal tricks you into sharing private information, such as your credit card number, by impersonating someone you trust.
Credit freezes and fraud alerts can help protect you from identity theft by making it harder for scammers to open new credit accounts in your name. They can also help stop someone who already stole your identity from misusing it again.
Here are a few indications you've been hacked:
If you've paid for something you haven't received, you might be able to get your money back. Your card provider can ask the seller's bank to refund the money. This is known as the 'chargeback scheme'.
Dial codes like *#21# or *#62# help check call forwarding settings, but they can't confirm if your phone is hacked. They're useful for spotting suspicious redirections, but use trusted antivirus apps for reliable threat detection.
To check if your phone is hacked, look for signs like rapid battery drain, unexpected data spikes, new apps you didn't install, strange pop-ups, slow performance, or weird noises on calls, then use reputable antivirus software, check your account activity, and dial codes like *#21# to see if calls are being forwarded, taking steps like changing passwords and resetting to factory settings if needed.
Beware of these warning signs:
Identity theft and financial fraud
If your name, address, Social Security number and/or national ID are found on the dark web, chances are they can be exploited to steal your identity. Financial fraud is the number-one way stolen data is used in identity theft cases.
Debit cards are linked directly to your bank account, which means that if someone gains access to your card information, they can potentially drain its entire balance. Additionally, online retailers have varying degrees of security, potentially leaving your information vulnerable to hackers.
The "15" and "3" refer to the days before your credit card statement's closing date. Specifically, the rule suggests you make one payment 15 days before your statement closes and another payment three days before it closes.
Here's how to tell if identity theft has already happened:
The 2/3/4 Rule is an informal guideline, primarily used by Bank of America, that limits how many new credit cards you can be approved for: two in a two-month (or 30-day) period, three in a 12-month period, and four in a 24-month period, helping lenders manage risk from frequent applications and "churning" for bonuses. It's a rule for applicants, not a limit on how many cards you should have, but a strategy for managing applications to avoid automatic denials.
Contact your debit or credit card issuer
Tell them that you fell for a scam and unintentionally gave the scammer your card number. The more information you provide about the scam, the more they can help you and protect your money. Your card issuer will cancel your card and mail you a new one with a new number.
Purchases you should avoid putting on your credit card

Reasons to Turn Computers Off
A primary reason to shut down your computer every night is for security concerns. Turning off your computer completely eliminates its vulnerability to remote cyberattacks and malware that rely on an active network connection or running processes.
Tools like stalkerware apps, often used by abusive partners, or financially motivated Android malware such as SpyLoan, have been detected exploiting cameras to monitor victims or collect compromising video material.”
Never provide your CVV to anyone unless you are making a legitimate purchase from a trusted and secure website or through a reliable payment gateway. Sharing your CVV can lead to unauthorized charges on your card.
Doesn't stop fraud that's already happened
Freezing credit can only help protect you against future fraud – not fraud that's already happened. And, identity thieves and scammers may still be able to gain access to existing accounts if they have your information, regardless of whether your credit is frozen.
Credit and debit cards may offer some protections that can help you recover your money for purchases you don't receive. If you pay with a credit card, your bank will likely reimburse you if you don't receive the goods. If you pay with a debit card, your bank will try to recover your money from the scammer's bank.
