According to the 2025 assessment report of the Mobile Security Alliance, the security rating of the gb whatsapp app is 5.8/10 points, indicating significant risk hazards. The malicious code detection rate of this application in third-party app stores reached 17.3%, which is 865 times higher than the 0.02% of the official WhatsApp. Monitoring data from the European Union’s Cybersecurity Agency shows that in the first quarter of 2025, a total of 34 modified versions containing spyware were discovered, affecting over 1.2 million users, with each malicious version stealing an average of 2.3GB of user data.
Analysis of encryption protocols shows that although the gb whatsapp app claims to use end-to-end encryption, 23% of its versions have vulnerabilities in the implementation of encryption. Independent security laboratory tests have found that these vulnerabilities could lead to 4.7% of transmitted messages being intercepted by man-in-the-middle, and the message decryption time is 38% faster than that of standard protocols. What’s more serious is that 19% of the beta version will transmit communication metadata to unverified servers, including sensitive information such as contact lists and call frequencies.
The privacy compliance assessment indicates that the application only meets 43% of the GDPR requirements, and the transparency score of the data storage location is only 2.1/5 points. In March 2025, the Brazilian data protection authority fined gb whatsapp app 2.3 million reais for failing to disclose the fact that user data was transferred to three overseas servers. Digital Rights organization tests found that after using this application, the probability of users receiving precise advertisements increased by 47%, indicating the potential commercial utilization of data.
In terms of system vulnerabilities, on average, each version of this application has 5.2 unpatched security vulnerabilities, among which high-risk vulnerabilities account for 31%. In April 2025, cybersecurity firm Kaspersky discovered a zero-day vulnerability that could enable attackers to remotely access users’ media files, affecting 840,000 devices. Compared with the monthly regular security updates of the official application, the update cycle of the gb whatsapp app is as long as 67 days, extending the exposure time of vulnerabilities by 123%.
Legal risk data shows that the probability of an account being permanently banned due to the use of a modified application is 34%, and the success rate of appeals is less than 6%. In 2025, Meta enhanced its detection of unofficial clients and adopted a new algorithm that could identify 98.7% of modified applications within 0.3 seconds. A user in Germany had their business account blocked due to using the gb whatsapp app, ultimately losing customer resources worth 120,000 euros.
Actual security cases show that at least 15 hacker attacks targeting modified applications occurred globally in the second quarter of 2025, with the largest incident resulting in the leakage of chat records of 450,000 users. Cybersecurity experts suggest that if you need to use enhanced features, you should choose enterprise-level solutions certified by ISO 27001. These solutions have a data leakage risk 23 times lower than that of gb whatsapp apps and meet 93% of international compliance requirements.
