This Is Why I Try To Wait For Proof

I'm fortunate in that I follow a lot of intelligent security professionals. When it was first announced that the Federal Bureau of Investigations (FBI) had hired a partner to break into Farook's iPhone 5C the speculation was that the partner was Cellebrite. Note the key word, speculation. Most of the people initially speculating on the topic were careful to couch their terms as hypothetical but that didn't stop media outlets from reporting speculation as fact. The problem with reporting speculation as fact is that it's often wrong:

The FBI cracked a San Bernardino terrorist’s phone with the help of professional hackers who discovered and brought to the bureau at least one previously unknown software flaw, according to people familiar with the matter.

[...]

The bureau in this case did not need the services of the Israeli firm Cellebrite, as some earlier reports had suggested, people familiar with the matter said.

When the media reports something as fact do yourself a favor and dig into the story. You may find out that the fact is actually speculation.
