Tens of thousands of people could have been caught out by cyber criminals who put booby-trapped adverts on popular webpages.The criminals racked up the victims by compromising the computers used by ad firm Unanimis to display adverts to popular websites.The ads appeared on the websites of the London Stock Exchange, Autotrader, the Vue cinema chain and six other sites.Unanimis said it moved quickly to pull the adverts once they were discovered.
