Boost Cybersecurity with Proven Signal-Like Apps: US Watchdog Issues Urgent Warning

Stay Safe: Use Secure End-to-End Encrypted Messaging Apps for Private Mobile Communications

As the latest cybersecurity alert from the US’ Cybersecurity and Infrastructure Security Agency (CISA) emphasizes, it’s crucial to protect your mobile communications from prying eyes. Following the massive "Salt Typhoon" attack, which targeted at least eight US telecom companies, CISA urges Americans to use only secure end-to-end encrypted messaging apps like Signal to ensure private mobile communications.

Signal and More Security Tips

While the CISA announcement focuses on highly targeted individuals, these security tips benefit everyone. First, avoid unsecured virtual private network (VPN) apps, which can compromise your data. Second, assume that all communications are at risk of interception or manipulation. To stay safe, switch to Signal-like communications apps that encrypt all data in transit, ensuring your messages remain private between the sender and receiver (end-to-end).

End-to-End Encryption: What You Need to Know

When selecting an end-to-end encrypted messaging app, evaluate how the app collects and stores metadata. Metadata refers to non-content information, such as IP addresses, timestamps, and data file sizes. This is why apps like Signal and Session are more secure than WhatsApp, which collects metadata. Opt for an app that is compatible with both Android and iPhone, allowing text message interoperability across platforms. Features like disappearing messages and images can enhance your privacy even further.

Securing Your Online Existence

CISA also recommends enabling phishing-resistant forms of two-factor authentication, such as Fast Identity Online (FIDO) with biometrics and physical security keys. Avoid using SMS as a second factor, as these aren’t phishing-resistant. Instead, utilize strong password manager tools like LastPass, Apple Passwords, or Proton Pass to store all login details and find strong combinations. Regularly update your device’s operating system software to patch vulnerabilities.

Additional Security Reminders

• Use a reputable, no-log VPN service, like NordVPN, with a strict security policy and strong features. Some free VPNs, like Privado VPN and Proton VPN, are also secure options.
• Regularly review and update your device’s security settings to ensure you’re protected.
• Be cautious when selecting a VPN, as many free and commercial providers have questionable security and privacy policies.

By following these simple yet crucial security guidelines, you can safeguard your online existence and remain safe in the digital world.
