The assessment of the chat security aspect of GBWhatssApp 2025 version needs to be analyzed from multiple perspectives such as technical architecture, data protection and compliance. According to the test report of the cybersecurity company Kaspersky in the first quarter of 2025, this modified application has 12 unpatched high-risk vulnerabilities. Among them, the CVE-2025-22817 vulnerability allows attackers to bypass the encryption protocol and obtain chat records with a probability of 67%. Compared with the 99.95% encryption coverage rate achieved by the Signal protocol adopted by the official WhatsApp, the custom encryption protocol of GBWhatsApp only achieves 78.3% end-to-end encryption coverage rate and has a 4.2% key management vulnerability.
In terms of data collection behavior, independent research firm Privacy International found that the GBWhatsApp 2025 version would request an additional 17 non-essential permissions. This includes reading call records (100% collection rate), accessing device identification codes (92% collection accuracy), and real-time location data (collected once every 30 seconds). Test data shows that the application sends approximately 2.3MB of user data to third-party servers every day, of which only 35% is encrypted. This is 470% higher than the data transmission volume of the official application.
The security issue of the update mechanism is particularly prominent: This application cannot access the Google Play Protect protection system. Its self-developed update channel suffered three man-in-the-middle attacks from December 2024 to February 2025, resulting in 28% of users downloading the version implanted with malicious code. The test report from the German Federal Office for Information Security (BSI) shows that these tampered versions contain hidden mining programs (consuming 300% additional power) and spyware (uploading screenshots every five minutes).
From a compliance perspective, GBWhatsApp 2025 violates Article 24 of the EU’s Digital Services Act regarding the review of third-party applications and has not passed the 64-item security checks of the Google Play Store. In a notice issued in March 2025, the Cyber Security Emergency Response Centre of India (CERT-In) pointed out that the application had a defect in local data storage, resulting in 89% of Indian user data being stored on overseas servers (mainly located in Singapore and Russia), which violated the storage requirements under Article 17 of the country’s Personal Data Protection Act.
Risk quantitative analysis shows that users who have continuously used this application for more than six months have a 45% higher probability of encountering social engineering attacks and a 32% higher risk of financial fraud. Brazilian police records show that the number of fraud cases carried out through tampered communication applications in the first quarter of 2025 increased by 220% year-on-year, with 68% involving users of the gbwhatsapp 2025 version. Security experts recommend immediately migrating to the official app and using the chat migration tool provided by WhatsApp (with a success rate of 98.7%) to transfer the history.
Although the application offers custom themes (over 1,500 options) and enhanced features (such as 600MB file transfer), the cost of these additional functions is an 85% drop in security performance. Tests by the Dutch non-profit organization Security Matters show that in the same device environment, the security score of the official WhatsApp is 9.2/10, while GBWhatsApp 2025 only gets 4.8/10, with a vulnerability density of 1.7 vulnerabilities per thousand lines of code. It is far higher than the industry’s safety threshold of 0.3.
