2022-02-24
A purported Moscow-based disinformation network, Pravda, allegedly infiltrated AI models by flooding the internet with pro-Kremlin falsehoods.

Pravda is part of Portal Kombat, a larger Russian disinformation network identified by VIGINUM in February 2024, but in operation since February 2022.
