If there's one company that's gotten a bit of good press from the Sony Corp. hacking scandal, it's BlackBerry Ltd.

The beleaguered entertainment company dug up old BlackBerrys to use after Sony's computers and landlines went down and company email was unusable after a cyberattack that began in November, the Wall Street Journal reported.

The emergence of the old devices as a haven for Sony executives has served as a free advertisement of sorts and bolstered BlackBerry Chief Executive Officer John Chen's focus on security to win government and business customers. The fact that Sony had to unearth devices long relegated to storage also highlighted that BlackBerry's share of the global smartphone market has fallen to less than 1 percent as iPhones and Android devices have gained ground.
