WhatsApp, the instant messgaing app used by over 3billion people, is widely known for its end-to-end encryption, which ensures that only the sender and recipient can read messages. Despite top security features, US House of Representatives officially banned the app from all House-issued mobile devices, over cybersecurity concerns.
The decision was outlined in an internal memo sent Monday by the Office of Cybersecurity. It mentioned WhatsApp as high risk App due to its handling of user data, lack of encryption for stored content, and exposure to potential security breaches.
However, experts note that this encryption doesn’t protect everything. Backups stored in the cloud (such as on Google Drive or iCloud) can be accessed by third parties if not properly encrypted. Additionally, vulnerabilities in devices or operating systems can be exploited through spyware or phishing attacks, allowing hackers to intercept communications or install surveillance tools without breaking the encryption itself.
WhatsApp parent company criticized the House’s decision. A spokesperson said, “We disagree with the move in the strongest possible terms,” and defended WhatsApp’s security framework. The company emphasized that the platform offers more advanced encryption protocols than some of the apps recommended by the House cybersecurity team.
Despite the ban, Meta continues to deepen its partnerships with the US government as the tech giant company is working closely with defense agencies to integrate AI technologies and has partnered with defense contractor Anduril on several national security initiatives.
WhatsApp ban comes after TikTok ban from all House devices and reflects growing unease over data privacy, espionage risks, and foreign surveillance.
WhatsApp Hacking
SIM Swapping & Hijacking
An attacker convinces your mobile carrier to issue a new SIM card in your name, gaining control over your phone number and receiving your WhatsApp verification code.
To protect yourself, Set up a PIN with your mobile carrier. Use two-step verification in WhatsApp. Avoid sharing personal info publicly.
Phishing
You’re tricked into sharing your 6-digit WhatsApp code, or clicking a malicious link that gives the attacker access.
Protect yourself: Never share your verification code with anyone. Be suspicious of urgent or emotional messages, even from friends. Don’t click on suspicious links, especially those asking for login info.
WhatsApp Web
Someone secretly scans the WhatsApp Web QR code using your unlocked phone and gains access.
Protect yourself: Regularly check and log out of unknown WhatsApp Web sessions. Don’t leave your phone unlocked or unattended. Enable screen lock or biometric lock for WhatsApp if available.
Malware
Malicious apps installed on your phone can read your WhatsApp messages, especially on rooted or jailbroken devices.
Protect yourself: Only download apps from official app stores. Avoid installing unknown APK files or granting unnecessary permissions. Use trusted antivirus/anti-malware software.
Voicemail Hacking
If the attacker knows your voicemail PIN, they can intercept the verification call and get the WhatsApp code.
Change your voicemail PIN from the default. Disable voicemail if not needed. Prefer SMS verification and always use two-step verification.
Safety Tips
- Enable Two-Step Verification: Go to Settings → Account → Two-step verification → Enable.
- Lock WhatsApp with Fingerprint or Face ID.
- Regularly review linked devices.
- Be cautious with public Wi-Fi and open devices.
- Keep your device’s OS and WhatsApp updated.
