New Delhi: Kanishk Sajnan says he did not receive so much as a thank you from a major airline when he contacted them with alarming news -- he had hacked their website and could book flights anywhere in the world for free.
- Ethical hackers used to find bugs by firms like Facebook
- Indian firms ignore them or threaten to sue them, they say
- Among ethical hackers are young computer science students
It was a familiar tale for India's army of "ethical hackers", who earn millions protecting foreign corporations and global tech giants from cyberattacks but say they are largely ignored at home, their skills and altruism misunderstood or distrusted.
India produces more ethical hackers -- those who break into computer networks to expose, rather than exploit, weaknesses -- than anywhere else in the world.
The latest data from BugCrowd, a global hacking network, showed Indians raked in the most "bug bounties" -- rewards for red-flagging security loopholes.
Facebook, which has long tapped hacker talent, paid more to Indian researchers in the first half of 2016 than any other researchers.
Indians outnumbered all other bug hunters on HackerOne, another registry of around 100,000 hackers. One anonymous Indian hacker -- "Geekboy" -- has found more than 700 vulnerabilities for companies like Yahoo, Uber and Rockstar Games.
Most are young "techies" -- software engineers swelling the ranks of India's $154-billion IT outsourcing sector whose skill set makes them uniquely gifted at cracking cyber systems.
"People who build software in many cases also understand how it can be broken," HackerOne co-founder Michiel Prins told news agency AFP
But while technology behemoths and multinationals are increasingly reliant on this world-class hacking talent, just a handful of Indian firms run bug bounty programs.
Information volunteered by these cyber Samaritans is often treated with indifference or suspicion, hackers and tech industry observers told AFP.
Anand Prakash, a 23-year-old security engineer who has earned $350,000 in bug bounties, said Facebook replied almost immediately when he notified them of a glitch allowing him to post from anyone's account.
"But here in India, the email is ignored most of the time," said Prakash, who runs a cyber security firm in Bengaluru.
"I have experienced situations many times where I have a threatening email from a legal team saying 'What are you doing hacking into our site?'"
This month Zomato, a food and restaurant guide operating in 23 countries, suffered an embarrassing breach when a hacker stole 17 million user records from its supposedly secure database.
The hacker "nclay" threatened to sell the information unless Zomato, valued at hundreds of millions of dollars, offered bug hunters more than just certificates of appreciation for their honesty.
The incident was especially galling for Prakash. He had hacked Zomato's database just two years earlier, and said if they listened to him then "they would never have been breached in 2017."
In a mea culpa rare for an Indian tech company, Zomato agreed to launch a "healthy" bounty program and encourage other firms to work with ethical hackers.
"We should have taken this more seriously earlier," a Zomato spokeswoman said in a statement to AFP.
Sajnani, who has hacked around a dozen Indian companies, said he was once offered a reward by a company that dropped off the radar once the bugs were fixed.
"Not getting properly acknowledged, or companies not showing any gratitude after you tried to help them, that is very annoying," the 21-year-old told AFP from Ahmedabad, where he hunts for software glitches in between his computer engineering studies.
In 2015, Uber-rival Ola launched what it called a "first of its kind" bounty program in India after hackers repeatedly exposed vulnerabilities in the hugely-popular app.
The Zomato hack, and panic surrounding this month's global WannaCry cyberattack, comes as the government aggressively denies suggestions its massive biometric identification program or Aadhaar is susceptible to leaks.
Prakash said it was vital the government embrace its own through a programme like the "Hack the Pentagon" initiative, which last year saw 1,400 security engineers invited to poke holes in the US Department of Defense's cyber fortifications.
"The Indian government definitely needs a bounty programme to make their system more secure," Prakash said.
