While Sony Pictures was left reeling from the massive and instrusive hack which revealed a ton of inside information and even saw various movies leaking before they hit theaters, it seems the company relied on BlackBerry devices and services in the wake of the unprecedented hack. Sony apparently dug up old BlackBerry devices after networks and landlines went down in order to communicate and keep the business running.
Reports are sketchy, but it seems that while Sony's internal servers and systems were eviscerated by hackers, older BlackBerry Enterprise Servers were relied on to enable communication on older BlackBerry handsets. BlackBerry, which is attempting a slow but sure resurgence in enterprise, might benefit from this sudden surge in high-profile security breaches.
