According to the 2023 Google Security Report, account suspension rate by the use of unauthorized GB WhatsApp download is as high as 32%, but it can be reduced to 7% through the use of device fingerprint camouflage technology. The key steps are creating an isolated environment with the assistance of Android virtual Spaces (such as Shelter), and regulating the deviation ratio between the hacked APK’s simulated IMEI parameters (the genuine device 358901045612345 is replaced by randomly provided values) and the actual device within ±0.3%. XDA BBS measured data reveals that if installation, disable “Google Play Protect” detection module (PM disable com by the ADB commands. Google. Android. The GMS /. Security. Snet. SnetService), It can extend the application life cycle from a mean of 3 days to 21 days. Meanwhile, there must be confirmation that the SHA-256 hash value of the APK is the same as the published value from the developer (e.g., 9A3F in release v17.80.). D82C) is a perfect match, and the error rate should be less than 0.001%.
Technical verification indicates that using the Dual Signature Bypass scheme can circumvent the client verification mechanism of WhatsApp. The concrete action is: Update the “package=”com.gbwhatsapp”” field in AndroidManifest.xml with APK Editor Pro and inject the anti-detection code module (about adding around 12KB to the size of the file) to let the app mask the ROOT status and Xposed framework traces from being detected during runtime. In accordance with Check Point’s cyber research, the above solution has the capability of decreasing the server-side risk control system’s device anomaly score from 78 points (the critical point for activating account suspension) to 29 points (within the security scope), but virtual positioning data has to be exchanged every 72 hours (within the latitude and longitude drift scope, which doesn’t exceed 50 meters).
User behavior pattern analysis indicates that the accounts with over 100 average daily sending messages or creating more than 5 groups of 200 individuals have a 47% higher chance of being blocked. It is recommended to turn on the “Anti-Ban” function built into GB WhatsApp download (path of settings:) (Chats > Mod Settings), adjust the send message frequency to 4 times a minute (default unlimited), and turn off “Last Seen” timestamp synchronization (downgrade server-side feature detection by 99%). The 2024 Brazilian user lawsuit demonstrated that batch messaging account users who employed tools such as AutoResponder experienced a 3.2 times higher rate of account suspension compared to accounts managed manually, and the success rate of unblocking was as low as 9% (the unblocking success rate of manually managed accounts was 38%).
When it comes to network layer defense systems, the application of IP address rotation technology (changing home proxies every 24 hours) will further reduce the risk of suspension of the account by 22%. According to the technical report, the authentic WhatsApp’s API request contains 17 device fingerprint parameters (for example, device_ram:4096, android_version:13). GB WhatsApp download ought to generate such parameters dynamically with Magisk module “WhatsApp Anti-Ban” so as to make the device fingerprint unidentical to the original client by 92%±3%. For curiosity, one observes that in the EU the Digital Services Act 2024 has the duty to ISPs for all third-party application traffic being recorded. It’s recommended that users enable VPN obconfusion features such as ShadowSocks+WebSocket to cloak the TCP data packet characteristics of GB WhatsApp as regular HTTPS traffic (port 443). Set DPI detection misjudgment rate to 85%.
