NoVoice Android Rootkit Infects 2.3 Million Devices via Google Play, Survives Factory Resets

McAfee researchers discovered the NoVoice Android malware distributed through 50+ apps on Google Play with at least 2.3 million downloads. The rootkit exploits 22 known Android vulnerabilities from 2016–2021 to gain root access and targets WhatsApp data theft. It establishes multiple persistence layers including system partition payloads that survive factory resets. The apps disguised as cleaners, galleries, and games required no suspicious permissions. McAfee noted similarities with the Triada Android trojan but could not attribute the campaign to a specific actor.

Analysis
The campaign's evasion architecture, combining genuine app functionality, no suspicious permissions, and deliberate reliance on vulnerabilities patched before 2022, reflects substantial investment in bypassing Play Store review while avoiding modern behavioral detections, per McAfee's sole technical account. System partition payloads survive factory resets, and affected users on pre-May 2021 Android security patches will likely require device replacement within the next several weeks. Triada-family similarities point to a sophisticated, financially motivated actor with prior mobile supply chain experience; the exclusive use of pre-2021 CVEs may instead mark a geographically constrained operation targeting markets with slow device update cycles rather than a global campaign.
