A malicious program used to create fake YouTube pages for infecting users is circulating on the web.

Cyber criminals send an e-mail promising a video with sensational content and encourage users to click a link to watch the video.
Users reach a fake page which is similar to the realYouTube site. They see an error message saying they can not watch the video as a certain component is missing, a codec or an Adobe Flash update, for instance.
They are then prompted to download it. On doing so, they download malware onto their computers.
YTFakeCreator lets cyber-criminals create these fake YouTube pages very easily, said PandaLabs.
They can enter the text for the error message displayed by the web page and define how long it takes the message to appear. The program also allows them to enter the link to the infected file downloaded onto the victim's computer, and create a false profile similar to those on YouTube to pretend the video has been uploaded by a real user.
The criminal can choose the type of malicious code to be distributed from these fake pages, such as viruses, worms, adware and Trojans.
"This type of program has led to increased use of this technique to infect users," said Dominic Hoskins, country manager at Panda Security UK. "The fact that the pages used by criminals are very difficult to distinguish from the legitimate pages helps ensure that a growing number of users are infected."
