  Internet of Things (IoT) is now omnipresent in all aspects of life and
provides a large number of potentially critical services. For this, Internet of
Things relies on the data collected by objects. Data integrity is therefore
essential. Unfortunately, this integrity is threatened by a type of attack
known as False Data Injection Attack. This consists of an attacker who injects
fabricated data into a system to modify its behaviour. In this work, we dissect
and present a method that uses a Domain-Specific Language (DSL) to generate
altered data, allowing these attacks to be simulated and tested.
