WhatsApp Users Warned: Spyware Vulnerability Threatens Personal Data
WhatsApp users are warned against sharing personal documents, following a security vulnerability that allowed criminals to install spyware. The Brandenburg Consumer Center and the Federal Office for Information Security (BSI) have issued alerts.
In September 2025, WhatsApp and its parent company Meta discovered a flaw in their app that affected Samsung smartphones. This vulnerability allowed attackers to remotely execute malicious code, potentially enabling the installation of spyware. The issue was reported to Samsung on August 13, 2025.
Millions of users send pictures and other sensitive docs via WhatsApp daily, making it a prime target for scammers. The Brandenburg Consumer Center advises against sending ID photos or other personal docs via WhatsApp or similar platforms. The BSI recommends sharing such information only through encrypted and certified channels.
Scammers often pose as legitimate entities to trick victims into sending personal docs. Unexpected messages asking for such information should be verified directly with the stated institution. Official and secure communication channels should be used instead of WhatsApp for sensitive information.
Identity theft can have severe consequences, including difficulties with debt collection, loans, and rental agreements. Victims may also find stolen data used to open illegal accounts or take out loans in their name. Users are urged to be cautious when sharing personal information online and to use secure communication channels for sensitive data.
