Looks like a massive attack. I wonder if the goal of the attacker is to short the stock.

Short interest on WDC isn't absurdly high, so, if that's the motivation, it's a pretty risky move to make not a lot of money.

You don't need short interest to make money shorting the stock. Short interest is useful for trying to squeeze people shorting the stock.

To make money off shorting the stock, all you need is for the stock to drop in price
