Identify the signs, understand the risks, and learn how to prevent data leaks, including through WhatsApp, Telegram, and other messaging apps
In today’s world, where data has become the new gold, information security is no longer optional — it is a strategic necessity. This challenge is even greater for businesses, which must protect their systems, communication channels, and employees against data leaks and other digital threats.
Many business owners still believe that leaks occur only through highly sophisticated attacks. The truth, however, is that most incidents originate from human behavior. Sharing sensitive information via messaging apps, using weak or repeated passwords, clicking on malicious links, and failing to monitor digital activity are all common entry points for cybercriminals. That’s exactly where solutions like Tuvis make a difference: monitoring channels such as WhatsApp and Telegram to ensure that communication with clients and partners happens in a secure and controlled way.
The damage caused by a data breach can be devastating. Beyond the exposure of personal customer information and unauthorized access to banking accounts or internal systems, there are also risks of fines and lawsuits for LGPD or GDPR violations and, most importantly, the loss of trust from clients, suppliers, and partners. Even worse, any employee, often unknowingly, can become the gateway for such incidents.
So, how can you tell if your company’s data has been compromised? Some clear warning signs include customers reporting suspicious contacts in your company’s name, internal information appearing on social media or forums, corporate accounts being hacked or blocked, anonymous messages containing sensitive data, and unusual access patterns in company systems. If your business relies on messaging apps for customer communication, every single message could potentially be a disguised threat.
Leaks typically originate from careless or malicious employees, lost or stolen devices without proper data protection, outdated software, or cyberattacks such as phishing, ransomware, spoofing, and SIM swap. On top of that, the lack of clear policies around internet use and corporate applications greatly increases vulnerability.
Cybercriminals employ a wide range of techniques, becoming more sophisticated every year. Phishing uses fake pages to steal credentials; spoofing involves identity fraud to trick employees or customers; SIM swap allows attackers to clone a phone number to access SMS-protected accounts. Other methods include ransomware, which locks up data in exchange for ransom; cryptojacking, where attackers secretly use company machines to mine cryptocurrency; brute force attacks to crack passwords; Trojans hidden in attachments or downloads; Zero-Day exploits that take advantage of newly discovered software flaws; and brushing scams, which use real customer data to generate fake reviews.
With the rapid growth of digital customer service, messaging apps have become strategic business channels — but also major risk vectors. Without proper monitoring, confidential conversations, customer data, and sensitive internal information can circulate uncontrolled. That’s why adopting solutions that combine security, monitoring, and compliance with regulations such as the LGPD and GDPR is critical.
At the end of the day, information security is not just the responsibility of the IT department — it’s the responsibility of leadership. Management must foster a culture of digital protection, ensure compliance with standards, invest in trusted technologies, and control access to data and communication channels. Only then can companies reduce risks and truly protect their most valuable asset: their data.
