I expect this to be bigger than Panama Papers. Way bigger. I expect a few prominent politicians to be soon either arrested or "convinced" to step down. I expect the US to have gained a lot of intel and leverage over those from the countries who did not participate in this. We will absolutely not learn about everything they discovered. CIA will and the respective intelligence agencies will.
EDIT: Europol will hold their conference live on YouTube at 10 AM CST: https://twitter.com/janoorth/status/1402164252266409987
EDIT 2: given how Serbia was in the top 4 of messages sent, I really hope that the info gathered will help Interpol fight child trafficking and exploitation in the EU.
From the VICE article (https://www.vice.com/en/article/akgkwj/operation-trojan-shie...) quoted elsewhere here:
"Additionally, the review of Anom messages has initiated numerous high-level public corruption cases in several countries. The most prominent distributors are currently being investigated by the FBI for participating in an enterprise which promotes international drug trafficking, money laundering, and obstruction of justice."
"Late Monday, the FBI said that it would be holding "a news conference announcing a massive worldwide takedown based on the San Diego FBI’s unprecedented investigation involving the interception of encrypted communications" on Tuesday."
