A Brazilian court is enforcing a constitutional ban on anonymity by requiring Apple and Google to remove Secret, an anonymous social network chatting app from their app stores. Microsoft is being required to remove Cryptic, a similar windows phone app.
In addition to that, they have been ordered to remove the app from the phones of all users who have installed it. These kinds of retroactive orders to have companies intrusively modify the contents of all of their customer’s devices are concerning. At least these apps are free, if users had paid for them, that would introduce another complication.
One wonders how this will apply to tourists or business travelers visiting Brazil. Will their phones be impacted as well?
The law exists to allow victims of libel or slander to identify and confront their those speakers.
While this ruling only applies to Apple, Google, and Microsoft, and only with respect to the Secret and Cryptic apps, the underlying principle extends much further. There are still final rulings to come, so this is not the last word on this situation.
Anonymizer has had a great many Brazilian customers for many years. Anonymizer provides those users important protections which are well established in international human rights law. We certainly hope that they will continue to be allowed to use our services.
On July 2, Google engineers discovered unauthorized certificates for Google domains in circulation. They had been issued by the National Informatics Center in India. They are a trusted sub-authority under the Indian Controller of Certifying Authorities (CCA). They in turn are part of the Microsoft Root Store of certificates, so just about any program running on Windows, including Explorer and Chrome, will trust the unauthorized certificates.
The power of this attack is that the holder of the private key to the certificate can impersonate secure Google servers. Your browser would not report any security alerts because the certificate is “properly” signed and trusted within the built in trust hierarchy.
Firefox does not have the CCA in its root certificate list and so is not affected. Likewise Mac OS, iOS, Android, and Chrome OS are safe from this particular incident as well.
It is not known exactly why these certificates were issued, but the obvious use would be national surveillance.
While this attack seems to be targeted to India and only impacts the Microsoft ecosystem, the larger problem is much more general. There is a long list of trusted certificate authorities, which in turn delegate trust to a vast number of sub-authorities, any of whom can trivially create certificates for any domain which would be trusted by your computer.
In this case the attack was detected quickly, but if it had been very narrowly targeted detection would have been very unlikely and monitoring could have continued over very long periods.
As an end user, you can install Certificate Patrol in Firefox to automatically detect when a website’s certificate is changed. This would detect this kind of attack.
On Chrome you should enable “Check for server certificate revocation” in advanced settings. That will at least allow quick protection once a certificate is compromised.
Update: Microsoft has issued an emergency patch removing trust from the compromised authority.
Continuing the pattern of Internet restrictions I talked about before, Russia has passed a new law requiring Internet companies to keep the personal data of Russians in data centers within the country. The ostensible reason for this is to protect Russians against US Government snooping (in the wake of the Snowden leaks), and against other outside threats.
The law requires that companies doing business in Russia must open data centers within the borders by 2016 or be blocked.
There are many ways for people motivated to bypass these restriction to access whatever they want, but most people will just use what is available, giving the Russian government more ability to monitor the activities of their citizens themselves.
The South China Morning Post reports that the ban on Facebook, Twitter, the New York Times, and many other sites, will be lifted, but only in the Shanghai free-trade zone.
The information came from anonymous government sources within China. The purpose is to make the zone more attractive to foreign companies and workers who expect open Internet access. The sources say that the more open access may be expanded into the surrounding territory if the experiment is successful.
It will be interesting to see if this actually comes to pass.
Two questions occur to me. First, will the free-trade zone be considered to be outside the firewall, and hard to access from within the rest of China? Second, is this as much about surveillance of activity on those websites as it is about providing free access?
Wired reports on a move by the Japanese government to ask websites to block users who “abuse” TOR.
I assume that TOR is being used as an example, and it would apply to any secure privacy tool.
The interesting question is whether this is simply a foot in the door on the way to banning anonymity, or at least making its use evidence of evil intent.
Currently, public privacy services make little effort to hide themselves. Traffic from them is easily detected as being from an anonymity system. If blocking becomes common, many systems may start implementing more effective stealth systems, which would make filtering anonymity for security reasons even harder.
