Hackerscollectief Antisec has the udids of a million users of iOS devices was published. Below are data of 10,000 Speakers. According to Antisec, were the data on the laptop of an FBI employee.
Antisec suggests data from a total of 12 million iOS users to have found on the laptop of the FBI agent. Including could include the unique device identifier, but also user names, names of devices, postal codes, telephone numbers, and postal addresses. With the udid, Apple-users be identified. The FBI employee would be in march, affected by a Java vulnerability.
From that mountain of data decided Antisec 1 million udids and device names on Pastebin to publish, in his own words of warning. In addition to the udid and the device name publish Antisec push-token, that can be used to push notifications to iOS users. Other private data by Antisec removed from the file.
According to the hackerscollectief is not clear why the private data on the laptop of an FBI employee were to be found, but is it possible to have a tracking project. From an analysis of Tweakers.net it appears that between the data published the udids of over 10,000 Speakers sit. This applies to devices where the device name is followed by the Dutch word ‘of’; it is therefore well possible that there are even more Dutch udids tussenstaan, of device names with a different structure. Why the FBI about the private data of Dutch and Belgians would have, is unclear.
According to Antisec are hard-coded user ids such as the udids is a bad idea, because they have a privacy form. Many applications use the udid to identify users, and to send the unique identification number, for example, to ad networks. Incidentally, Apple has already taken measures to make use of the udid by developers, to ban.
