Han Bing, the former database administrator of Lianjia (Beijing) Technology Co., was sentenced to seven years in prison for damaging computer information systems at the first trial, according to the Chinese Judgment Document website.

It is reported that on June 4, 2018, Han Bing, the database administrator of Lianjia (Beijing) Technology Co., LTD., took advantage of his authority as the "root" of the company's financial system to log in to the company's financial system, and deleted the financial data and related applications in the system, which made the company's financial system completely inaccessible.

The damaged servers are two database servers and two application servers specially used for the EBS system of the company, which store all the financial data of the company since its establishment and directly affect the salary payment of the company's staff, which is of great significance to the entire operation of the company.

The company spent 180,000 yuan to recover the data and rebuild the system.
