The Expert’s Voice: How to protect our data on WhatsApp and Telegram

Preventing and mitigating the impact of cyberattacks that result in data breaches on social messaging networks such as WhatsApp or Telegram, involves a combination of technological tools, advanced methodologies, the integration of strategic intelligence, Open Platform Intelligence (OSINT) and dark web analysis.

Some of the practical strategies recommended by the experts of the ITE Intelligence Unit to achieve this would be:

1. Implement Strategic Intelligence tools

These tools help anticipate threats and make informed decisions:

• Threat Intelligence platforms that can monitor emerging threats related to specific groups of cybercriminals, by analyzing historical patterns of attacks, thus detecting specific threats on messaging platforms such as WhatsApp, Telegram Messenger, Signal Messenger, etc.
• Predictive analytics using machine learning to predict potential attacks based on the attackers’ historical behavior, performing real-time analysis to identify potential gaps in messaging systems.

2. Use of OSINT methodologies

Open systems intelligence (OSINT) makes it possible to collect useful information from public sources:

• Monitoring social networks with advanced searches for indicators of compromise (IOCs) such as filtered emails, IPs, or malicious users.
• Metadata analysis through the analysis of documents, images, and other publications shared on these networks to detect patterns of misuse or risks.
• Tracking suspicious groups on public platforms, detecting forums or communities sharing sensitive methods or data.

3. Dark web exploration

The dark web is a key source for identifying compromised data before it is used to do so:

• Proactively monitor to identify data breaches or mentions related to WhatsApp or Telegram users.
• Identify specific threats with research in forums, black markets, and other environments to identify malicious actors who could be planning or reselling leaked data.
• Profiling attackers using dark web information to track activities related to specific groups, linking them to previous cyberattacks.

4. Security Practices

Implement safety measures by combining tools with security policies to strengthen resilience through:

• Strong authentication, implementing methods such as multi-factor authentication (MFA) to reduce the risk of unauthorized access.
• Advanced cryptography ensures messaging apps use up-to-date end-to-end encryption and monitors for vulnerabilities in their deployments.
• Use of advanced encryption tools and secure communication with robust encryption for the protection of critical communications, including the protection of sensitive mobile devices, ensuring security against #ciberamenazas and electronic espionage.
• Security audits with penetration testing of messaging platforms to identify potential weaknesses.

5. Detection and response strategies

The use of strategic intelligence and OSINT and dark web methodologies also supports early detection by:

• Automation in anomaly detection using systems such as SIEM (Security Information and Event Management) to alert on unusual activity on social media accounts.
• Real-time alerts, configure specific alerts for keywords, IOCs or patterns detected in OSINT or dark web investigations.

6. Training and awareness

Users are a key link in protection, so it is essential:

• Train in cybersecurity, teaching users to identify scams, #phishing and signs of intrusions on WhatsApp, Telegram or other platforms.
• Apply good data handling practices, limiting the exchange of sensitive information and promoting the use of secure tools to transfer data.

7. Collaboration with external entities

Working with authorities and experts strengthens the defense, so it is necessary to:

• Share intelligence by cooperating with other industry players to exchange information on new threats.
• Proactively report, quickly reporting malicious groups found in OSINT investigations and on the dark web to the relevant authorities.

The expert’s conclusion

Taking these steps will create a comprehensive approach that combines prevention, detection, and response to cyberattacks and data breaches.
