Suspicious/malicious file with binary incoded as base64 ofuscating as png image

SberSwapInference.ipynb

what it is this code trying to pretend its a png hiding with base 64 inside that file?

**this is not cool at all.**

passed from suspicious 40% threat to malicious 80% when I told the sandbox to open web browser.

The base 64 got me curious.
97% of the file size is of base 64 that's not a png despite saying its a png

**What is it** ? I suspect the sandbox to be racist with anything sounding slavic.
