WOOF locker is the most sophisticated browser locker campaign we’ve seen to date. Learn how this tech support scam evades researchers and ensnares users by hiding in plain sight. It is a social engineering technique that gives the illusion of a computer virus and scares people into calling a toll-free number for assistance. To this day, this campaign is still active on the MSN portal. It is quite daring to push your browlock right on Microsofts own start page. For a campaign to run with such a wide distribution and for this length of time is unheard of.”]
