The browser does this because it is a lot faster for your browser to load the website locally, opposed to downloading the website from the internet again. This is because you browser stores a copy of the website on your computer.
You may have noticed that when you return to a website you’ve visited before, it loads a faster than it did when you first visited it. However, there have still been concerns raised by some analysts like Roel Schouwenberg, a researcher at Kaspersky Labs, that Chrome OS users are as vulnerable to malicious apps from the Chrome marketplace as much as Android users are at risk from malicious apps in the Android marketplace.How to hard refresh your browser and clear your cache. However, as Google closed the competition, it said: "We did not receive any winning entries but we are evaluating some work that may qualify as partial exploits." It's still good news for Google, which markets Chrome OS at consumers with emphasis on its robust security and "virus-free" ecosystem. They had good incentive to find holes, too, as Google was offering $110,000 (£74,000) for every "browser or system level compromise in guest mode or as a logged-in user" and $150,000 (£100,000) for every "compromise with device persistence, guest to guest with interim reboot", up to a total of $π million. Pwniums 1 and 2 were set up by Google in previous years to focus on the Chrome browser, but its inclusion in Pwn2Own meant they shifted focus to Chrome OS for Pwnium 3 - and even with an extended deadline, it came away without suffering a serious breach.Įntrants to Pwnium 3 were given a Samsung Series 5 550 Chromebook and 28 January through to 2pm on 7 March to look for holes, a deadline that was extended until 5pm at the request of frustrated hackers.
Pwn2Own set a challenge of finding zero-day exploits in popular browsers, which this year meant the latest versions of Firefox, Internet Explorer, Safari and Chrome, running on either Windows 7 or OS X Lion. However, hackers did manage to find holes in the Chrome browser at the parallel Pwn2Own event, winning hundreds of thousands of dollars in the process.īoth Pwnium 3 and Pwn2Own were part of this year's CanSecWest security conference in Vancouver, where hackers gather to win prizes put up by large tech companies for finding vulnerabilities in software. Google's Pwnium hack event went off well this year, as none of the attendees managed to find a security flaw in Chrome OS that would win them part of the offered prize of $3,141,590 (£2.1m).
