Question: How did Hendricks know Ethan and the IMF team were in the Kremlin that day?

Answer: Ethan's briefing said that IMF had "learnt" that Cobalt was en route to the Kremlin to destroy his identity records in the archives, at a specific time right down to the minute. As having IMF present to frame for the bombing was part of his plan, it is likely Hendricks leaked his own intentions to IMF knowing they would send a team to retrieve the records. After Ethan has his ID scanned, Hendricks turns and walks away like he was waiting for them to arrive, and may have scanned their frequency.
