It has been interesting to notice how unimportant and ineffective cyber operations have been in the Russia-Ukraine war. Russia launched a wiper against Ukraine at the beginning, but it was found and neutered. Near as I can tell, the only thing that worked was the disabling of regional KA-SAT SATCOM terminals.
It’s probably too early to reach any conclusions, but people are starting to write about this, with varying theories.
I want to write about this, too, but I’m waiting for things to progress more.
EDITED TO ADD (3/12): Two additional takes.
