gb whatsapp provides message anti-recall (can see and save the other party deleted messages), but its technical implementation and security is much worse than the official solution. On the basis of 2024 results from Technical University of Berlin testing, gb whatsapp’s retraction prevention feature comes with local caching and a successful recovery rate of just 78% (the official WhatsApp lacks it, however, third-party compliance tool WAMR realizes a success ratio of 95%). And because of the code vulnerability density of 7.2/1000 lines (industry security standard ≤1/1000 lines), 38% of the recovered messages were tampered with or injected malicious links (e.g., phishing sites). For example, out of 23 messages recovered by User A from India, five contained fake bank links (click-through ratio of 12%), and one stolen account of $1,200 ensued.
The security threats are immense. The Kaspersky report shows gb whatsapp’s recall anti-module being rooted in unencrypted local storage (AES-128 vs official ECC-256), and its attackers can draw out historic messages with physical touch devices (89% success rate) or by exploiting remote weaknesses (e.g. CVE-2024-36921). Black market per unit price 0.85 USD/piece. In the “AntiDeleteHack” incident in Brazil in 2023, attackers took advantage of the feature to steal 890,000 business order messages for a decryption fee of 0.3 BTC/person (around $6,800), and Meta suspended 41% of gb whatsapp related accounts annually (according to article 4.2 of the terms of Service).
Legal and compliance issues are foregrounded. The EU General Data Protection Regulation (GDPR) requires complete enforcement of the right to erasure, but gb whatsapp’s anti-retraction feature prevents user data from being completely deleted (92% non-compliance). In 2024, a German court ordered an e-commerce company to pay a 45,000-euro penalty for applying the feature to retain private customer data (retention period of 180 days) (official WhatsApp Business zero offenses). Additionally, the CPU usage of the anti-retraction process increased from 15% to 58% (tracked by Snapdragon 732G), power consumption daily increased by 37% (4.2Wh→5.8Wh), and the rate of low-end device crashes (e.g., Redmi 9A) was 34% (official 5%).
There is a cost of performance and efficiency. gb whatsapp’s anti-recall function takes a toll on permanent background operations (peak memory 512MB, official without this module just 120MB), delaying message synchronization from 0.3 to 1.7 seconds, and retrieval of 10GB historic messages taking 3.8 hours (official compliance modules just 1.2 hours). Indonesian user B, for example, put the CPU under load (peak temperature 48°C) from using this feature, and repairing the motherboard cost $85.
The other is economically and technically superior. Although official WhatsApp does not have native retraction capability, WhatsApp Business has compliance software such as WAMR ($9.9/month), has a 95% success rate in recovery, and data encryption is GDPR compliant (0.001% risk of breach). According to 2024 market statistics, 83% of enterprise users use the former, which saves $980 a year in security costs (and $85 a year in latent costs for gb whatsapp users).
In summary, gb whatsapp’s anti-withdrawal feature results in data risk (38% rate of message tampering), legal costs (45,000 euros penalty suits) and equipment degradation (CPU loading +287%), and transient convenience cannot override systemic risks, reasonable users must employ GDPR certification instruments to ensure compliance and safety.
