Yep. Looks like it was fixed fast. It doesn't change the fact that is was worth to pass it here. People should know what happend before next validation because I still see risks. For example during next validation we may have 2100-3500 toxic flips, 700 toxic nodes voting on flips. I would really consider killing my node if I was suspended/zombie.

Full announcment:

"A new version of the Idena app is available: 0.18.0

Changes:
- A critical vulnerability fix in the flip randomization algorithm. The vulnerability enabled an attacker to identify the right answer of a flip without solving it, with a high probability.

We will monitor the situation. The vulnerability report will be published after the upcoming validation ceremony.

Please update your Idena app (https://idena.io/?view=download).

🚨 The update is required for a successful validation.

Please submit new flips using the new app version only."
