Is it summer? Let's check...

OK, I took this app (check_summer.exe) that calculates checksums and fed some data into it, including flag:

So now you only have CRC32 of the flag, good luck recovering it from eight hexes, HAHA!!

(wait, wait, what are you doing?

aaaagh where are you dragging me)

— OK, Vlad doesn't know that, but we inserted a hardware implant into his CPU to record every instruction executed.

Here is the trace corresponding to the events shown in the video above: check_summer_rtrace.txt

Please use your technical skills to recover the data being checksummed. We really need that flag.
