Russian hacking undermines trust in Signal app among EU diplomats

The Signal messaging app, widely used by European Union diplomats, journalists, and activists, has been compromised by Russian intelligence in Germany and the Netherlands.

These breaches have raised serious concerns about the security of sensitive communications within the EU.

Investigations confirmed that Russian hackers targeted Signal users in Germany and the Netherlands, with Dutch intelligence reporting attacks as early as March 9.

In April, senior EU officials responded by shutting down a Signal group amid fears of further hacking.

The breaches have disrupted secure communication channels and undermined confidence in Signal as a trusted platform.

Data from the black market shows that Signal chat content can be purchased for between $10,000 and $20,000, depending on the target's seniority.

This is significant because Signal has been the preferred secure messaging app for security-conscious EU diplomats and activists.

The repeated intrusions and data leaks have eroded trust in the app's ability to protect sensitive information.

Additional intelligence reveals that personal data such as travel histories, medical records, banking and tax information, and even dating website usernames are available for sale.
