Emerging Techniques in Bank Fraud

Noticias ao Minuto reports on a growing trend in bank fraud. The scheme often starts with someone impersonating a bank employee, displaying what seems to be the bank’s official number on the caller ID.

The dialogue is persuasive, filled with urgency, mentioning threats like “account blocking” or “suspicious activity.” The aim remains consistent: to extract personal details, online banking access, or SMS verification codes.

The Bank of Portugal (BdP) notes that these types of scams—referred to as phishing, smishing, or vishing depending on the approach—have evolved into more intricate and hard-to-detect methods. Criminals frequently use spoofing to mask their phone numbers and email addresses, making them look genuine.

According to the agency, these scams are often built around “plausible scenarios” such as needing to update personal information or unlock accounts.

In several instances, fraudsters gather real information about their victims through social media or previous data breaches, which helps foster trust and diminish suspicion.

The BdP warns that scam texts typically contain brief, alarming phrases, hastily written to provoke an immediate reaction.

“Fraudulent communications are usually urgent, making it easy for personal information to be shared quickly, without much time for contemplation,” the agency cautions.

Once a victim falls for the ruse, they unwittingly share their access codes, and the scam can be completed in mere minutes.

Staying Safe

The BdP advises against sharing personal details, passwords, or authentication codes over the phone, via SMS, or email, even if the inquiry seems legitimate. It’s crucial to verify the sender’s address, language, and message format. Misspellings or visual inconsistencies are significant warning signs.

Additionally, Noticias ao Minuto emphasizes avoiding clicking on links or opening attachments from suspicious messages. If you’re uncertain, it’s best to contact your bank through official methods and promptly report any suspected fraudulent activity.

If you find any unauthorized transactions, BdP recommends that you notify your bank and file a report with the local authorities, such as PSP, GNR, or PJ judicial police.
