The Threat
Sophisticated cloud-based virtual devices mimicking real user hardware.
The Impact
Large-scale automated abuse that bypasses standard security checks.
Legacy Failure
Traditional emulator detection relies on software flags that are easily spoofed.
The Solution
TrustSig uses deterministic hardware attestation to verify physical silicon.
These are server-side instances that simulate mobile hardware. Unlike local emulators, they are often hosted in data centers and can be scaled to perform massive automated attacks.
Many Runtime Application Self-Protection (RASP) tools look for specific software artifacts or flags. High-end virtual environments can mask these indicators, making them appear as genuine consumer devices.
TrustSig does not rely on software flags. We challenge the client's hardware and rendering environment. Because virtual devices lack the unique physical silicon characteristics of a real phone, they cannot pass our deterministic tests.
The Evolution of Automated Abuse
In 2026, the landscape of automated fraud has shifted. Attackers are moving away from simple scripts and local emulators toward high-end, cloud-based virtual devices. Platforms that allow for the remote execution of mobile environments are becoming the preferred tool for sophisticated bot operators.
These virtual devices are not just simple emulators. They are powerful, server-side instances that can be spun up in the thousands. Because they run in the cloud, they can easily rotate IP addresses and mimic the network behavior of legitimate residential users, making them incredibly difficult to block with traditional security stacks.
Why Legacy Defenses Are Falling Behind
Many existing security solutions, such as those used in mobile SDKs for payment or authentication, rely on Runtime Application Self-Protection (RASP) features. These features typically look for specific indicators like:
- Root or jailbreak status.
- Presence of debugging tools.
- Known emulator software flags.
While these checks are effective against amateur scripts, they are increasingly ineffective against professional-grade virtual environments. These environments are designed to be "stealthy," actively stripping away or spoofing the very flags that RASP tools look for. If your security relies on checking for a "virtual" flag, you are likely missing the most sophisticated threats.
The TrustSig Approach: Deterministic Hardware Attestation
At TrustSig, we believe that the only way to win the arms race against virtualized fraud is to stop looking for software flags and start verifying the hardware itself.
We do not ask the device if it is an emulator. Instead, we challenge the environment to prove it is running on physical silicon. By analyzing the unique, deterministic signatures of hardware rendering, CPU thread concurrency, and audio context evaluation, we can distinguish between a real mobile device and a server-side instance.
This process is invisible to the end user and requires no CAPTCHAs. It provides a definitive, binary answer: is this a real device, or is it a virtualized instance? By moving the verification to the hardware layer, we ensure that even the most advanced cloud-based virtual devices are identified and blocked before they can interact with your application.
