These Massive Swings In the Market Due to Hackers?

I just don't see how its based on 'rates' We knew rates could be going up and priced in 7 rate hikes.

Meanwhile, we still have low interest rates, massive amounts of QE still being injected each month.

Now we see the Russian Stock market drop names by 50% in a day…..Our stocks making 50% swings intraday that are worth tens of billions. Makes me wonder if our hackers are battling

​

I wonder if 'state' actors are glitching out algos and causing forced selling and we aren't hearing about this because everyone would panic if they realized what was happening.

​

Any insight on this? I just pray APPLE/MSFT/GOOGL is really secure. A breach of those companies by Russia would cause markets to drop by 50%+ in a day if all our data got taken
