Developer behind encrypted app Signal working on Apple’s CoreOS Security team
While it is highly likely Jacobs will be involved in making Apple’s operating systems more secure, there is also the outside chance he is being brought onboard for another purpose. The FBI has repeatedly asked Apple to create some form of tool to allow access to encrypted data stored on an iPhone, a move the company has resisted so far, but in the unlikely event it is compelled to produce the tool, Jacobs would be one likely candidate to work on such a project.
As part of Open Whisper Systems, Jacobs worked on Signal, a highly secure messaging app used by whistleblower Edward Snowden. The app has been praised for revealing “virtually nothing” when messages sent from it were analyzed, with anEFF scorecard also providing it with top marks when compared against other messaging apps for security. Jacobs spent two and a half years at the company, before leaving this year.
