Apple used the Digital Age Copyright Act (DMCA) to remove a tweet with a possible encryption key for the iPhone security chip. Twitter obeyed, and then the company changed its mind and the service re-published the deleted record. This was reported by Motherboard.
On December 8, a cybersecurity researcher, under the pseudonym Siguza, published a tweet with a possible encryption key for the Secure Enclave chip. It stores encrypted personal information of users, including logins and passwords.
Two days later, lawyers at Apple worked with Twitter to remove the record due to copyright infringement. The service obeyed and the tweet became unavailable, but on December 12 it was returned back.
Apple confirmed to Motherboard sending the first request, but noted that it was later withdrawn, but by then Twitter had already deleted the post. After that, Apple asked the service to return the publication and it became available again.
At the same time, DMCA requests were received at Reddit. They were related to jailbreak subreddit publications. Section moderators noted that the administration did not contact them in connection with the removal of any content, but just in case the community decided to ban the publication of new jailbreak entries for an indefinite period.
As cybersecurity researchers have suggested, this Apple behavior may be related to the fight against jailbreaks. In September 2019, an enthusiast under the pseudonym axi0mX published information about a vulnerability that affects all devices on chips from A5 to A11 (to iPhone X).
A few weeks later, other researchers released the checkra1n jailbreak tool , which circumvents the protection of the latest version of iOS 13. Although the vulnerability remained only on devices of the year before last, it turned out to be a great success for the jailbreak community after many years of lack of public tools.
They just completely lost the jailbreak battle on iPhone X and later. So now they are trying to start legal litigation in order to spend our time, money and effort.
