Meanwhile in Norway much of this wouldn't matter because the accessed information would have been public anyway. The non-tax PII is still a loss of course.
I'm surprised. The stolen data had two parts: some relevant to the income taxes paid, some detailing the real estate (houses and lands) owned by the household. Are both of them public in Norway?
Anyway, the main problem is that the breaches into the many French national data stores seem increasingly frequent.
Those same countries that treat financial privacy as axiomatic are trying their best to undermine chat encryption and would throw ed Snowden in prison given half a chance.
