National Security is the chief cause of national insecurity
Governments spying your encrypted communications
Slovak Information Agency (SIS) repeatedly wants to change a legislation to implement backdoors for any "legal" encrypted communication
Czech Military Intelligence Service ("Vojenská rozvědka") wants to put "blackbox" sniffing devices (with a secret functionality) to all Czech ISPs/mobile operators
The government's fight against end-to-end is global (e.g. Cameron also wants to ban the end-to-end encrypted communication in the UK)
The question:
What is a political legitimity of such dictatorships proposals?
If someone wants to propose a law for "tagging" Jews with a yellow star, should we consider him to be serious?
If not, why we take seriously the institutions like SIS, Czech Military Intelligence or crazy politicians?
What can we learn from Wikileaks I.
Slovak SIS and Czech secret police bought a special hacking malware (FinFisher/Galileo) from companies which provable work for dictatorship regimes (i.e. tax payers' money are used for supporting dictatorship-friendly companies)
Because these special hacking tools use 0-day exploits (tools for exploiting not-revealed yet 0-day vulnerabilities which are not patched), for citizens there is ALMOST NO WAY to protect their digital privacy against these dangerous tools
Huge asymmetry between the government and individuals
There is no transparency at all (!) how to reveal this dangerous government's activity, because everything is top-secret & classified
Reaction of Czech Police
Everything is OK because the hacking malware is used for "legal purposes"
Analogy:
Is it OK to use tax payer's money to buy guns from ISIS terrorist organization just because they are used for "legal purposes only"?
What can we learn from Wikileaks II
Recent leak of hacking tools of CIA
CIA knew about 0-day vulnerabilities of millions of Internet users exposing them to potential attacks of all Internet criminal gangs
CIA threatened Internet corporations not to fix these vulnerabilities, because it's a (leaked) classified information exposing of all their customers
CIA behavior presents a significant threat to all Internet users (!)
No information about our privacy without whistleblowing
Unfortunately, whistleblowing is becoming the only way how to reveal these immoral government's practices regarding our digital privacy
More corrupted or misused power -> more leaks
Less "official" transparency -> more leaks
It's a shame that despite of leaks, often nothing is changed (e.g. the most serious political corruption leak in Slovakia - "Gorila")
Impact of government's privacy interventions
All system with government's backdoors will be weakened leading to significant decrease of citizens' digital privacy, especially when sufficiently secure privacy solution will be blocked
Central government "storage" system (data retention, EET, ..) can be always misused - by potential hackers or corrupted employees
The most serious threat for your privacy is government's agencies
Because they are:
Usually completely non-transparent (classified)
Monopolized (with the impossibility of bankrupt in case of leak of huge amount of sensitive information)
Used 0-day very efficient spying malware with no possibility for citizens to defend themselves
Unlimited financial sources (compared to the private sector)
Protect yourselves against government's spying & tracking
Encrypt all your calls and messages (Signal)
Encrypt all your instant communication (Jabber+OTR)
Encrypt all your email-communication (PGP, S/MIME)
Encrypt your Windows (Microsoft Bitlocker)
Encrypt your Linux / Mac (dm-crypt/LUKS, FileVault)
