“We need to verify your account”: how to spot fraud without losing your cool

In a world where digital payments and online services are part of everyday life, fraud no longer always announces itself clearly.

Nancy Rueda was checking her WhatsApp when a message suddenly caught her attention: “We need to verify your account to avoid suspension. Please confirm your details here.” It came from a number that looked legitimate and claimed to be her bank. Almost without thinking, Nancy began typing her ID number and account password. Then something felt off. She remembered that her bank repeatedly warns customers that it never asks for passwords or sensitive information through messages or calls. “I got scared, but I realized I was facing a fraud attempt,” she said.

What Nancy experienced is far more common than it seems. It is known as phishing, a tactic in which scammers impersonate trusted institutions to trick users into handing over personal data and, ultimately, their money. In Colombia, cybersecurity experts warn that fraudulent calls and messages are among the most widespread forms of digital fraud, especially as online payments and financial services continue to expand.

These schemes do not succeed only because of technical sophistication, but because they exploit a key asset of the digital ecosystem: trust. Trust that messages arrive when they should, that services work smoothly, and that the platforms people interact with every day behave as expected. Fraud slips into that sense of normality and imitates it.

How do these scams work, and why are they effective?

Scammers take advantage of both trust and speed. More than technical labels, these frauds share a single logic: triggering a quick reaction before the user has time to question what is happening. Smishing: text messages or WhatsApp messages that appear official.

Phishing: emails with links that redirect to fake websites.

Vishing: phone calls from people claiming to be from a bank or a public utility.

Fake promotions on social media or e-commerce websites.

According to TransUnion Colombia, more than 218,000 digital fraud claims were reported in the first half of 2024. At the same time, over 99.9 percent of digital transactions were completed without irregularities. The data shows that while the risk is real, modern systems detect most attempts before they reach the user.

What banks do behind the scenes

While users may only notice a suspicious message, fraud prevention systems are constantly at work in the background. They analyze usage patterns, flag unusual transactions, block access from suspicious locations, and trigger early alerts to stop fraud before it happens.

In practice, these systems are not designed to respond once fraud has already occurred, but to absorb risk as part of normal operations. They read behavior, cross signals, and make decisions in milliseconds so that the user’s daily experience remains uninterrupted. When everything works as intended, the user notices nothing at all. That silence is a sign that prevention is doing its job. All of this happens without disrupting regular use. The most robust systems protect quietly, without forcing people to monitor their accounts every minute.

At institutions such as Bancolombia, prevention starts even before customers are aware of it. The bank uses authentication measures and activity monitoring to confirm that “the person trying to log in or make a transaction is really you.” A core element of this approach is layered authentication, which combines multiple verification steps to make it harder for unauthorized third parties to access an account. On its official website, the bank explains that this process ranges from username and password login to transaction confirmation through dynamic codes or biometric tools such as fingerprints or facial recognition on compatible devices.

“We take into account your device, your location, the time of the transaction, the amount, and the institution you are sending money to or receiving it from, among other data, to ensure that your personal information and your money are really being moved by you and not someone else,” the bank states. The idea is not to demand constant vigilance from users, but to build an environment where constant alertness is unnecessary.

In Panama, banks deliver a similar message. Banco General, for example, emphasizes that it “will never ask for usernames, passwords, or card numbers through messages or emails,” and advises customers to distrust urgent-sounding communications or those with spelling mistakes, a common red flag in fraud attempts.

At its core, digital security is not measured by the complete absence of fraud attempts, but by the ability of systems to contain them without shifting the burden onto users. Digital trust does not mean nothing can go wrong. It means there is an infrastructure designed so that risk does not interrupt everyday life. When prevention is invisible, it is not because it is missing, but because it is working, allowing people to keep paying, transferring, and using digital services without constantly thinking about danger.
