melita norwood is just a normal socialist english girl who smuggled documents on nuclear bombs to the soviets.
the colonial pipeline hack's loss was redeemed via some sorta omnipresent trace on tor, where bitcoin changes hands. now this is probably due to three facts:
- the US has stellar hackers who're loyal to the US government (and probably the nation. you don't get snowden and think the rest are less loyal. sigh.)
- the US has TOR (basically a US navy project)
- bitcoin is the earliest cryptocurrency and has many bad designs (george hotz went into some detail showing why ethereum is much better designed than bitcoin)
yet melita norwood exist. KGB would easily trade the cambridge four for norwood. why? she probably shortened the soviet nuclear program by five years. (otherwise the US would be the only nuclear nation for five more years. if they're modestly decisive china will change hands, and russia would probably follow. at that point i don't think the russians can get their act together to make an a-bomb.)
so...perhaps somewhere in the pentagon, there is a russian and / or chinese backdoor. even an iranian backdoor. who knows. this bacdoor might give the respective nation a very high-level access. but if such backdoor was ever discovered, the US will be much much more vigilant than before, rendering a second attack impossible.
so the probability TOR is hacked by another nation / individual / group is P(US hacked). but P(US hacked) is smaller if P(US hacked)*P(US discovered that it is hacked) in an earlier time is larger...
but george hotz is right, security is fundamentally a lost cause. modern systems are too complex to defend.
there doesn't seem to be anything here
