Daily digital interactions expose personal and financial data that can end up in the hands of cybercriminals if extreme precautions are not taken. The Instituto Nacional de Ciberseguridad de España warns that information such as name, email, phone number, address, or even bank details can be compromised in different scenarios.
Leaks and targeted frauds
One of the main risks lies in digital platform leaks. When a security breach occurs, databases with email addresses, passwords, postal addresses, phone numbers, and billing data can be exposed. This information is especially valuable for subsequent fraud campaigns.
From that data, criminals use social engineering techniques to try to access more information or achieve bank transfers. Among the most common methods are phishing via email, smishing via text messages, and vishing via phone call. The objective can be to obtain credentials, trick the victim into transferring money, or get them to install malicious software on their devices.
Insecure downloads and credential theft
Malware continues to be another of the most used ways for information theft. It can extract stored passwords, session cookies and financial data once it manages to install itself on the computer or on the mobile. The infection usually occurs after downloading programs from unofficial sites, opening attached files or installing browser extensions without guarantees.
That access allows attackers to take advantage of credentials already saved by the user and enter digital services without needing to directly break passwords. The risk increases when keys are reused in multiple accounts or the permissions of installed applications are not reviewed.
The overexposure on social media
The information that many people share publicly on social media also facilitates more precise attacks. Dates of birth, photographs showing addresses, vehicle license plates, or personal routines serve to create detailed profiles. With that data, personalized deceptions can be designed that are more credible for the victim.
The combination between filtered data and public content multiplies the possibilities of fraud. An email or a call appear more truthful when they include personal references, habits or daily information previously obtained on the internet.
Basic protection measures
Given this scenario, INCIBE recommends strengthening the security of accounts and devices. Among the priority measures are activating the two-factor authentication, keeping operating systems and applications updated, and having an up-to-date antivirus as well. These are basic steps, but they remain crucial to reduce exposure to unauthorized access and digital fraud campaigns.
