VANCOUVER, Canada -- When it comes to hacking, it turns out that greed really is good.
All four of the major desktop browsers, plus two Adobe browser plug-in
programs, succumbed to the predations of the hacker community in two
different contests.
Pwn2Own, sponsored by Hewlett-Packard and organized by the HP-owned
Zero-Day Initiative, featured up to $1.085 million in prizes, and
security researchers going after Adobe Flash and Reader, Apple
Safari, Google Chrome, Microsoft Internet Explorer, and Mozilla
Firefox.
Eight research teams earned $850,000, with another $82,500 going to
charity for Pwn4Fun over the two-day competition, which concluded on
Thursday at the CanSecWest conference at the Sheraton Wall Hotel here.
HP has summarized results for
Day One and
Day Two
The new Pwn4Fun charity contest saw Pwn2Own co-sponsor Google nailing
Apple Safari for $32,500, while Pwn2Own organizer Zero-Day Initiative
hit Internet Explorer for $50,000. Both teams donated their prizes to
the Canadian Red Cross.
Why security hacking is becoming more lucrative Team Vupen of
Vupen Security
scored the most cash with $400,000, the most that any single Pwn2Own
team has ever won. Vupen Chief Executive and Chief Researcher Chaouki
Bekrar said to not let the high value of the prizes fool you: browser
security, he said, is improving.
"The major value of Pwn2Own is to show that even the most secure
software can be compromised by a team of researchers with enough
resources," he said just after knocking off Google Chrome, the first of
two contestants this year to do so.

But, he said, there's more value to the competition than just the lucrative prizes.
"Since we report the vulnerabilities to the vendors, they fix the flaws
and [then] they harden the browser to prevent future attacks." Browsing
in general becomes safer for everybody, Bekrar said, as browser vendors
learn from each other's mistakes.
Brian Gorenc, the manager of the Zero-Day Initiative, agreed that the
larger prizes are having a two-fold impact on the day-to-day security of
what's likely to be your favorite browser.
"Microsoft, [Adobe] Flash, and
Google were all patched before the contest. The vendors are definitely trying to put their best product forward," Gorenc said.
"The major value of Pwn2Own is to show that even the most secure
software can be compromised by a team of researchers with enough
resources."

He said that reflects the growing trend where companies respond somewhat
faster to reported bugs. The average two years ago was 180 days, but
that's down to 120 days now.
Meanwhile, Gorenc said, the growing prize pot is attracting researchers
like nerds to an arcade game. This year saw the highest number of
entries in the decade-long history of the contest, at 16. It's getting
to the point where security researchers can make in one contest enough
to live on for a year, but it's not easy. There are strict requirements
for proving your newfound vulnerability and exploit.
Where Vupen spent around four to six weeks to earn its prize money, Keen
Team, from China, scored $65,000 for hacking Apple Safari and
co-hacking Adobe Flash. They will donate some of their winnings to a
Chinese charity for the people missing on
Malaysian Airlines flight MH370.

Keen Team senior researcher Liang Chen said it took three months to
develop those exploits, but he clarified that factors such as operating
system and browser version can affect how successful an exploit is.
"Desktop Safari is harder to hack than on
iOS 7 because [Apple] will implement the latest security enhancements more often," he said.
Not all the software up on the Pwn2Own chopping block lost its head.
Bekrar's Vupen withdrew from scheduled attempts at Oracle's Java and
Apple Safari, although he might've passed on Safari because the Keen
Team successfully exploited it an hour earlier -- possibly with the
exploit he had discovered.
One researcher failed at an Internet Explorer hack, although the browser succumbed to other attempts.
Left unscathed was the highest single prize of the contest, $150,000 for
the "Exploit Unicorn." This rare beast demanded a specific hack:
system-level code execution on a Windows 8.1 x64, in IE 11 x64, with an
Enhanced Mitigation Experience Toolkit (EMET) bypass.
Pwnium for hacking Chrome OS
Google held its own concurrent one-day hacking contest on Wednesday this
week, giving security researchers a crack at Chrome OS and a
grand total of $2.7 million in cash rewards.

Google would not reveal the number of participants, but George Hotz, a
well-known researcher known on the console hacking scene as "Geohot" won
$150,000 for an exploit chain six deep on the HP Chromebook 11. A
second participant is up for a partial reward on the same device. Hotz
also claimed one of the four $50,000 Firefox exploits at Pwn2Own.
Chris Evans, a Google security engineer who has been on the Chrome
security team since Google began building the browser, echoed a similar
note to Gorenc, Bekrar, and others in Vancouver this week: If you want
high-quality security, you have to pay for it.
"The prize is high," Evans said, "because the amount we can learn from
it is high. We can close whole classes of bugs, while devising new
hardening measures."
Evans said that across all Google security rewards programs, which
includes its regular Chrome bug bounty, the Google Search bug bounty,
and the Pwnium event, the company has paid more than $3 million for
bugs. That includes this week's Pwnium awards, and is accelerating:
Google crossed the $2 million mark
only seven months ago.
"We've gone from 2 to 3 really fast," he said. "The more money we can
put into the "white hat" community, the better off we all are."

"We've gone from 2 to 3 really fast," he said. "The more money we can
put into the "white hat" community, the better off we all are."
Evans said that the impetus at Google to improve security is driven by a
desire simply to be better than the bad guys, and part of that is
acknowledging and fixing previously-unknown vulnerabilities and
exploits. He made it clear that Google feels it wins when it can point
to lessons learned, such as the three losses by Chrome and Chromium this
year.
"Bad guys are fundamentally lazy," Evans said, then added, "like the rest of us."
They're looking for the highest return with the least amount of effort, he said, put Google's goals in game-show terms.
"They want the weakest link," he said, "and we will never have Chrome be the weakest link."
