The Privacy BlogPrivacy, Security, Cryptography, and Anonymity

CAT | Anonymity

Sauron-BrazilA 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.

Tor just announced that they have detected and blocked an attack that may have allowed hidden services and possibly users to be de-anonymized.

It looks like this may be connected to the recently canceled BlackHat talk on Tor vulnerabilities. One hopes so, otherwise the attack may have been more hostile than simple research.

Tor is releasing updated server and client code to patch the vulnerability used in this attack. This shows once again one of the key architectural weaknesses in Tor, the distributed volunteer infrastructure. On the one hand, it means that you are not putting all of your trust in one entity. On the other hand, you really don’t know who you are trusting, and anyone could be running the nodes you are using. Many groups hostile to your interests would have good reason to run Tor nodes and to try to break your anonymity.

The announcement from Tor is linked below.
