It has been revealed in recent report that a version of Internet Explorer that was being used on a fully secured Windows until now would soon be introduced in an annual Pwn2Own hacker competition.

The report has uncovered that the hacker competition is held at an annual basis for testing how internet software resists to real-world attacks. As per the report findings, the hackers had full access to the underlying laptop as they had exploited two of the unknown vulnerabilities in version 9 of the Microsoft browser, which are being run on Windows 7 SP 1.

It is being said that a security sandbox is put on internet software as protections by companies so as to protect these from being hacked by attackers. A security sandbox is used to funnel web content into highly restricted perimeter overlooked by operating-system functions responsible for performing sensitive actions like modification of registry settings.

The report says that companies like Google and several others use data execution (DEP) and address space layout randomization (ASLR) as well to ensure safety of software like Google Chrome. But, attackers tend to seek out some or the other way to hack these.

The report has also revealed that security is an arms race that is fought between hackers so as to lode different types of sophisticated espionage malware, which are used for investigate on internet firms.

It has been unveiled that the team of hackers from France-based Vupen Security had penetrated Chrome's sandbox on Wednesday, and as per the CEO of the company, Chaouki Bekrar, the group has not only attacked Chrome but, IE, Safari, Mozilla Firefox and Apple as well.

"The (new) protected mode is much more secure, much more restrictive. IE 10 on Windows 8 will be a big challenge for us to create an exploit for it", said Mr. Bekrar.
