GB WhatsApp download’s update cycle is subject to high uncertainty and lag. According to the third-party application analysis site APKMirror’s statistics in 2023, the version cycle of unofficial modified applications is between 15 and 90 days (the official WhatsApp is 21 days), and only about 47% of distribution sites can keep up with the latest version. For instance, the v19.85 version released in March 2024 was delayed in push on popular platforms such as gbdownload.io for up to 12 days, which made the message synchronization error rate of users due to version mismatch as high as 18% (the error rate of official channels was only 0.3%). According to a study by Symantec, a security company, such delays reduce the effectiveness of vulnerability fixes by 65%. For example, for the CVE-2022-36934 vulnerability disclosed in 2022 (in which remote code execution is achievable), the official released the patch within 48 hours, but the patched version of GB WhatsApp download took 37 days.
Technically, from a maintenance perspective, GB WhatsApp’s development team lacks a normalized update mechanism. The 2024 open-source code audit discovered that the number of unpatched high-risk vulnerabilities in its codebase was 3.2 times that of the official app (with an average of 12.7 vulnerabilities with CVSS score 7.0 and above per version), and the security patch coverage rate was only 61%. For instance, Indian user Rajesh Patel was hit by “two-factor authentication bypass” in November 2023 because he didn’t update GB WhatsApp download on time (still using v17.30), lost the bank’s OTP SMS verification code, and had his account scammed for $540. Meta’s 2024 compliance report reveals that the breakdown rate of digital signature verification for altered third-party applications is as high as 29%, further hindering users from receiving trusted updates.
The cost of active updates by users is also higher than official applications. Since GB WhatsApp download cannot be automatically pushed through Google Play or App Store, users have to manually download a total of 45MB of APK files on average, with a median time cost of 4 minutes and 22 seconds (compared to updates from the official app store which takes only 38 seconds). In a survey in 2023 by Brazil’s Communications Authority, 43% of users chose to delay the process of updating due to its complexity, extending the time their devices were exposed to identified threats to 68 days (3 days for official users). One such example is Nigerian trader Adanna Nwankwo, who delayed the update. His GB WhatsApp chat database was encrypted by ransomware in January 2024. It cost 0.3 bitcoins (approximately 13,000 US dollars) to restore the data access rights.
Fragmentation of distribution channels exacerbates the update problem. In Kaspersky Lab’s experiment, among all GB WhatsApp download installation packages propagating globally in 2024, 32% of them were tampered with and injected with advertising SDKS or spyware modules (such as Xavier malware). Even where the version numbers were the same, the hash value match rate was only 56%. For instance, in the “v18.60 version” downloaded by the Dhaka, Bangladesh student community through various websites in September 2023, 13% of the samples generated firewall warnings, with an additional 22 minutes spent on file verification and re-download. On top of that, Meta has exerted pressure via the law, which has caused the rate of the large distribution sites (e.g., APKPure) removing GB WhatsApp to increase to 2.3 per month in 2024. The users have been pushed onto more clandestine but insecure secondary sites, and the success rate of updates is down to 71%.
Although some developers assure to provide “regular updates”, their technical investment is far inferior to what is demanded by compliance. Reverse engineering research in 2023 shows that in the GB WhatsApp download codebase, only 38% of security updates actually fix vulnerabilities (the rest are feature overlays), while the vulnerability fix rate of the original app is 94%. For example, the “Media File Hijacking” vulnerability (CVE-2022-24084) that risked 200 million users in 2022 was temporarily fixed by the GB WhatsApp team by simply disabling the preview feature, and the complete patch took 141 days (the official took 19 days). It is estimated by Gartner that the maintenance of those unorderly updates is 2.7 times more expensive than that of the authoritative model (between $9 and $45 implicit expenditure every year per user on average), and the cross-device compatibility fault rate has been increased to 14% due to version fragmentation.
Concisely, the update support of GB WhatsApp download is far inferior to the official channels in terms of timeliness, security, and stability. According to the 2024 report of the European Union Cybersecurity Agency (ENISA), the mean data breach risk annually for its users due to delayed or failed updates is 19.3%, 7.8 times higher than that of official application users, and the median expense of its restoration is 127 US dollars (9 US dollars for the official application).
