On the other hand, there have been widespread DDOS attacks as well as some pretty high-profile compromises of the Russian computing and network infrastructure. You can even help if you'd like - https://stop-russian-desinformation.near.page/.

I think though the ruble will weather the storm; it is mostly used internally in Russia, the interest rates have been yanked up to 20%, and Russia still exports massive amounts of commodities (how they get paid I don't know? Chinese Yuan and Indian rupees maybe ...).
Either that, or oligarchs are moving hidden assets back to Russia. Either because they worry they will he discovered or to take advantage of the falling Ruble to buy the other half of the country. Or maybe it's because the market of people buying rubles is really thin right now, and this is an attempt by the Russian government to manipulate the price and public opinion.
But this exchange rate has become pretty meaningless. Hardly anybody is either willing or allowed to give you USD for your RUB. If you own russian stock you are currently unable to sell it for rubels anyway. This currency is on it's way to non-convertible status.

/edit:
Since this happens russia banned the transfer of foreign currencies. This is a massive step towards the rubel being non-convertible.
I think that means that russia effectively defaults on almost all debt. But while I think so, but no body else mentions it, so I probably did overlook something.
