According to Kaspersky Lab’s 2025 Mobile Security Report, the so-called gb whatsapp apk that supports dual-open functionality has serious security risks. Test data shows that this modified version of the application creates two independent sandbox environments, with each account occupying an average of an additional 187MB of storage space and increasing the CPU load by 62%. When dual accounts are running simultaneously, the peak temperature of the device can reach 48°C, far exceeding the official safety threshold of 36°C for single-account operation, causing the battery life degradation rate to accelerate by 3.3 times.
Technical analysis shows that the dual-account function, implemented through code injection, will trigger the Android system’s protection mechanism. The EU Cybersecurity Agency’s detection found that 83% of the modified applications had permission abuse issues, with each account instance requesting 27 system permissions (the genuine version only requires 11), among which 15 involved access to sensitive data. What’s more serious is that 69% of the data transmission during the dual-account synchronization process is not encrypted, increasing the risk of information leakage by 400%.
Actual operation data shows that the dual-on function has led to a significant decline in performance: the failure rate of message sending has risen from 0.2% in the official application to 13.8%, and the video call lag rate has increased by 270%. Among the 2,000 tested devices, running dual accounts simultaneously kept the median memory usage at 1.7GB (the official single account was only 720MB), which increased the probability of other applications crashing by 44%.
Security experts point out that this dual-account mechanism violates Article 4.5 of the WhatsApp Terms of Service and may result in the main account being permanently banned. In 2024, 340,000 users in Brazil experienced account freezes due to using the dual-account feature, with an average data recovery cost of 120 US dollars. The genuine WhatsApp Business application supports the official dual-account function and adopts ISO 27001-certified isolation technology. The probability of data leakage between the two accounts is only 0.0001%.
From a compliance perspective, the modified dual-opening function is suspected of violating 128 global data regulations. Records from India’s Ministry of Information Technology show that in the first quarter of 2025, 56% of data breaches were related to dual-opening applications, with victims losing an average of 89 pieces of private information. The genuine solution achieves secure account separation through Work Profile technology and automatically performs 217 security checks every 24 hours, while the modified application completely bypasses these protection mechanisms.
Professional institutions strongly recommend using the official multi-account solution: The native Work Profile feature of the Android system can create a completely isolated second account. All data encryption strength reaches 256 bits and is monitored in real time by Google Play Protect. Although the revised version claims to offer convenient dual opening, the cost is a 78% drop in security performance and potential legal risks – according to the Digital Millennium Copyright Act, such modifications could result in statutory damages of up to $200,000.
