Firm defends Hong Kong vote from online attack

1

BEIJING: Two weeks ago, Matthew Prince, the chief executive of San Francisco tech company CloudFlare, had no clue that people in Hong Kong were preparing to hold a controversial online referendum on democratic reforms.

By Thursday night, half a world away from the southern Chinese city, he found himself on the front lines of a battle to defend the nonbinding, unofficial vote from sabotage.

Amazon Web Services and Hong Kong’s UDomain had initially been onboard to support and protect the voting web site. But at the last minute, both bowed out, saying the expected size of the cyberassault could affect their other customers.

That was a somewhat worrying sign for Prince and his team, whose small, five-year-old company specializes in making web sites run more quickly and smoothly and preventing disruptions, and recently launched a pro bono service for situations just like this.


Going it alone, Prince and about 20 employees gathered in their office near 3rd and Townsend streets and girded for a test of their wits and ingenuity. As Friday morning broke in Hong Kong and the 10-day vote began, the fight was on.

Under fire
The web site, popvote.hk, was being flooded with requests that look like legitimate users trying to call up or contact the site. The queries were being sent by armies of commandeered computers, known as botnets, around the world. At the height of the assault, more than 200 million requests were coming in every second, Prince said—a clear bid to overwhelm the site and knock it offline.

“It was easily one of the largest the Internet has ever seen, on any metric,” Prince said in a phone interview, adding that the attacker or attackers kept changing strategies.

“It felt like there was an intelligent adversary on the other side that was not just trying one technique but adopting new techniques to try to find ways around our mitigation efforts,” he added.

Measured by another metric, the attack generated 300 gigabytes per second of traffic, according to CloudFlare. That’s like downloading nine high-definition movies per second, every second, according to an expert at GreatFire.org, which monitors Internet usage, censorship and hacking in China. On top of that, attackers chose methods that chewed up a lot of central processing unit server resources at CloudFlare.

“The volume of the attack is impressive; so is its sophistication,” said the GreatFire.org expert who requested anonymity for fear of retaliation.

Halfway into the balloting, the attacks are persisting, but the efforts of Prince’s team seem to be working—no major outages have been reported and more than 700,000 people had voted by Tuesday evening, organizers said. That’s nearly 10 percent of the city’s population, and a far greater number than organizers anticipated.

Neither CloudFlare nor officials at the University of Hong Kong’s Public Opinion Program—which designed and administered the voting web site on behalf of a local civic group—could say where the attacks are being directed from.

“We don’t have any strong evidence . . . but there’s lots of speculation that it’s coming from China,” said Karie Pang, assistant director of the Public Opinion Program.

“We have reported it to police. . . . Maybe one day we can get to the monster behind the scene,” he added.

The balloting has been organized not by the city government but by a local civic group called Occupy Central with Peace and Love. The results are nonbinding, but those behind the effort hope that the process will help push forward democratic reforms in Hong Kong, a former British colony that reverted to Chinese rule in 1997 but retains a high degree of political autonomy from the Communist-led mainland under a legal framework known as “one country, two systems.”

Participants in this week’s referendum are being asked to express a preference for one of three methods of selecting the city’s chief executive in 2017, the first time the balloting is supposed to be open for a citywide, one-person, one-vote election.

But authorities in Beijing have denounced all the options on the referendum as illegal and the referendum itself as “invalid.” Ahead of the referendum, China issued a white paper essentially admonishing Hong Kong citizens not to push things too far—and warning that Beijing has final say over all matters in the city.
