'Pravda' Network, Successor to 'Portal Kombat,' Allegedly Seeding AI Models with Kremlin Disinformation
2022-02-24
A purported Moscow-based disinformation network, Pravda, allegedly infiltrated AI models by flooding the internet with pro-Kremlin falsehoods. A NewsGuard audit found that 10 major AI chatbots repeated these narratives 33% of the time, citing Pravda sources as legitimate. The tactic, called "LLM grooming," manipulates AI training data to embed Russian propaganda. Pravda is part of Portal Kombat, a larger Russian disinformation network identified by VIGINUM in February 2024, but in operation since February 2022.
