The Washington Post is reporting right this very second that North Korea's Internet is experiencing usual "blips" and outages. Firms that monitor Internet performance on the Korean peninsula say the slowness is characteristic of a cyber attack.

Remember when President Barack Obama said the U.S. would respond "appropriately" to the North Korean hack on Sony Pictures? Could this be it?

No one is likely to die. It won't topple the government, but it does appear to be an "appropriate response."

Do you know how the U.S. used to punish Kim Jong-Un's father, Kim Jong-Il (remember him? Old fat guy with crazy hair?) They would freeze his personal bank accounts!

The Kim family keeps secret bank accounts worth billions in small banks around Asia and Europe.

In the first half of the last decade, much of that money was in banks in Macau (tiny, independent island off the coast of China near Hong Kong). In 2005 the U.S. froze all the accounts in Banco Delta Asia, prompting every other Macau bank to close their North Korean accounts, and the Macau government to beef up its anti-money laundering laws.

The money frozen in this move was Kim Jong-Il's personal spending money!

In 2007 the U.S. gave the money back in return for the country shutting down its nuclear program.

Since then, North Korea has moved its money to hundreds of fake accounts in Shanghai, Switzerland and more.

But how much do you want to bet the U.S. knows where the money is?

Banco Delta Asia is still blacklisted from doing business with American firms as punishment.
