I seen this on the nightly news a few days ago about how they hacked into Russian telephones, banks, power, etc.

As someone who has experiences with programming, I feel like if they designed well thought systems there is a low chance there'd be hacked. Brute force detection, permission/access controls, etc. Plus by the US putting all this in the media, doesn't that tell Russia they should go ahead and scan their network?

Plus the companies that sell these equipment to Russia, the middle east and even China probably also sell to the US most likey. So if there are any vulnerabilities they are using to hack Russia, the same ones could probably target US Infrastructure too if it's the same vendors software running on them...
