“The fact is, no one expects to find malware hidden in YouTube files. Yet the medium’s popularity is highly alluring as a mass distribution vehicle for malicious code,” says Secure Computing’s Paul Henry according to the same source. “What’s alarming is that - from a security perspective - many users and organisations will be blindsided and potentially seriously exposed.”

Obviously, it’s very hard to determine if a certain clip is dangerous or not as there is no software solution able to discover this type of threats. Moreover, YouTube doesn’t filter the content uploaded on the page to block the malicious clips so the danger is even bigger.

“Over the last seven days, two major threats have been exposed that relate to these sites: Pfizer lost the personal details of 17,000 staff members after a company laptop was used to access a P2P network that deposited a ‘back door Trojan’ on the device,” says Alex Raistrick of ComSentry for Tech.co.uk.

The popular online video sharing service YouTube was acquired in October 2006 by the Mountain View company Google that paid no less than $1.65 billion. Since the acquisition was made, YouTube grew up a lot, becoming a revolutionary service for most of the Internet users. Take for example the police officers who were trying to resolve important cases with the help of YouTube. They uploaded surveillance clips on YouTube in a move meant to obtain valuable information from the registered members and other viewers of the clips.

Microsoft’s primary stated objective with Windows Vista, however, has been to improve the state of security in the Windows operating system. One common criticism of Windows XP and its predecessors has been their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, Microsoft chairman Bill Gates announced in early 2002 a company-wide ‘Trustworthy Computing initiative’ which aims to incorporate security work into every aspect of software development at the company. Microsoft stated that it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, thus delaying its completion.

Windows Vista has been the target of a number of negative assessments by various groups. Criticism of Windows Vista has included protracted development time, more restrictive licensing terms, the inclusion of a number of new Digital Rights Management technologies aimed at restricting the copying of protected digital media, and the usability of other new features such as User Account Control.
