However, how about AT command firmware?
Yesterday, I ran AT+CIUPDATE. But AT+GMR reports
AT version:188.8.131.52(Sep 20 2017 19:34:38)
compile time:Sep 20 2017 20:32:34
Is this version affected by KRACK (WPA2 attack)?
First, open the resources page of ESP8266:
ant click the check mark (looks like a letter v) at the right of AT.
(DO NOT click 'SDK & Demos'. As of writing this, the AT firmwares there are still old ones.)
Then a table will appear.
Confirm that release date is 2017.11.06 (or later) and click the download icon.
You'll obtain a zip file containing new firmwares.
Alternatively, if your current AT firmware is capable of AT+CIUPDATE, then you might want to try it.
Hope this helps.
