Technology giant Apple is not just cagey about its future products but also about its acquisitions. As it has been recently revealed that Cupertino-based company acquired firmware security company LegbaCore in November 2015.

The acquisition came to light, courtesy security researcher Trammell Hudson. Hudson first revealed the acquisition in his presentation at the 32C3 conference in December.

It was further corroborated by a series of tweets from LegbaCore founder Xeno Kovah. He revealed on Twitter that he and his partner Corey Kallenberg have joined Apple as full-time employees.
