Many people enjoy small moments of the day, such as waiting for someone, having coffee or traveling, to perform online tasks. This apparently harmless routine can, however, compromise the security of your bank data and other sensitive financial information.
According to Business Money, a company that specializes in cybersecurity, one of the most frequent practices among internet users, using public Wi-Fi to access banking services and other sensitive accounts, is also a favorite of cybercriminals to access unauthorized bank data.
Almost imperceptible attacks
An attacker can position himself between the user and the site being visited, in a technique known as Man-in-the-Middle attack. In these cases, even if the bank’s website is legitimate, the information the user inserts can be intercepted.
This type of attack is difficult to detect as navigation seems to last. However, bank data such as account numbers, safety codes and passwords are vulnerable to access by the attacker.
Another frequent danger is false access points, created to seem legitimate and leading the user to provide personal data on a controlled connection by third parties.
The lock is not always synonymous with security
Although many bank websites use the HTTPS protocol, indicated by the lock next to the address, it does not guarantee total safety. There are techniques that can circumvent this protection, especially when the original connection is not safe.
In addition, using outdated software devices increases the risk as strikers can explore known failures to access the user’s system and collect information without it.
Even the presence of antivirus may not be sufficient if the user has careless navigation habits. The combination of insecure bonds and negligent practices facilitates the work of criminals.
Simple measures that make a difference
It should be avoided, whenever possible, banking operations on public internet networks or unsuccessful.
Alternatively, it is recommended to use a mobile network or a VPN (virtual private network), which creates a safe connection between the device and the servers.
Keeping operating systems and applications up to date is equally important to correct vulnerabilities and reduce the risk of intrusion.
It is also advisable not to automatically store words in browsers, as this functionality, although practice, can facilitate unauthorized access if the equipment is compromised.
Millions of Portuguese are exposed daily without knowing
According to, a very significant number of people are exposed daily to these threats. It is estimated that millions of Portuguese access to the internet through mobile phone in public spaces, often without being aware of the dangers this represents to the protection of their financial data.
The best way to protect yourself is through information. Know the way these threats operate and what risks involved helps create safer digital habits in everyday life.
This common practice, often performed by habit or convenience, can have serious consequences. Staying alert and protecting your data is critical to preventing sensitive information from falling into wrong hands.
