Yang Wei is so good at solving thorny online security problems, and so in demand, that he hasn't had any rest over the past two months.
Yang, 24, who works for WooYun, the largest employer of white-hat hackers in China, was on the road to Shanghai last week to provide security technology training and organise offline security salons.
"I never thought I would be exhausted as a security employee, but I find it is not an easy job," Yang said.
Despite his youth, Yang has become a key player at WooYun, sharing his security knowledge with online communities and working with companies to resolve their security issues.
Younger people like Yang form the majority of China's white-hat hackers, a type of Internet expert known for identifying security problems, but not exploiting them for personal gain.
According to a report released by GeekPwn, an online security community, and Tencent, a large Chinese technology company, more than 60 per cent of white-hat hackers in China were born after 1990, and they are becoming younger.
Neither the report nor the country's cyberspace authority have released the exact number of white-hat hackers in China. But WooYun, for example, which was founded in 2010, has more than 7,200 security staff members.
Some of the young generation have talent in handling security risks and most of them have a broader understanding of the industry than their predecessors, said Guan Mochen, technical director of Kingsoft Security, a large national security provider.
They are also shouldering more pressure and facing bigger challenges, Guan said.
The report said that 84 per cent of Internet users think the yearly income of security staff could be more than 100,000 yuan (S$22,000), and 21 per cent think they could earn more than 500,000 yuan.
But, in fact, the yearly income of 55 per cent of the white-hat hackers is less than 100,000 yuan, it said.
Most security employees with just two years of working experience cannot demand a high salary in the field, Yang said.
"Even those who have mastered the key technology and can solve difficult security problems have not been paid what they deserve," Yang said.
Guo Xunping, vice-president of Bangcle, a mobile network security company, said talented security experts deserve higher incomes, but pay still trails.
Salaries may be lower than desired, but white-hat hackers keep busy. Yang is a frequent flier, and he complains that he has no personal life.
"Since June, I have always been on a flight to Shanghai, Shenzhen, in Guangdong province, or Hangzhou, Zhejiang province, during the weekends, and it is still going on," he said.
"I am physically and mentally exhausted, but I am still persisting because I love the security job and always have a great passion," he said.
In the past, he supplied online security testing for companies, but with the fast development in the industry, he needs to handle many issues in person and through on-site training.
"In this way, I have to go to the companies to communicate. After all, some thorny or complicated security risks are not suitable to discuss in calls or on the Internet," he said.
Additionally, as a leader of the white-hat hackers at WooYun, Yang also is in charge of contacting companies in different cities and calling them regularly to share new industry findings.
Liu Hui, 25, who has a doctorate in security from Shanghai Jiao Tong University, said it is not difficult for her and her classmates to find security jobs, but identifying high-paid work without frequent business trips is challenging.
