Phone farms

How phone farms work

Advanced phone farmers use a variety of tactics to hide their activity, including hiding behind fresh IP addresses, using a broad variety of devices, while either enabling Limit Ad Tracking or hiding behind DeviceID Reset Fraud (resetting their DeviceIDs with each install).

When perpetrated at scale, this type of fraud is also known as DeviceID Reset Marathons.

Though device farms are often portrayed as a fraud-type that is based in Asia, our research has found device farms operating across the world, and advertisers around the world are impacted by this fraud.
