Cyberattack

The room fell into deep silence when the head of the IT department barged into the room running and looked worried. 

Grandfather Gu looked at the man and pursed his lips, " What happened? What is so important that you came barging into the room like this?"

The man took a deep breath before saying, " Sir, There is a big problem which needs your urgent attention." 

Grandfather Gu frowned but waited for his explanation. The man glanced at Gu Zhang before continuing, " The computer in Mr. Gu Zhang's office seems to have been hacked by someone."

" One of my employees went to his room to check the computer when his secretary informed some technical issues this morning. However, those don't seem to be general technical issues but seem like it has been hacked by someone." His voice became low by the end of it. 

Gu Zhang's eyes widened upon hearing this. " What? How can it be possible? It was fine just yesterday."
