Security researchers are accusing Apple of abusing the Digital Millennium Copyright Act (DMCA) to take down a viral tweet and several Reddit posts that discuss techniques and tools to hack iPhones.

On Sunday, a security researcher who focuses on iOS and goes by the name Siguza posted a tweet containing what appears to be an encryption key that could be used to reverse engineer the Secure Enclave Processor, the part of the iPhone that handles data encryption and stores other sensitive data.
