Facebook, MySpace and YouTube are the most commonly blacklisted sites at organizations, according to a new report from OpenDNS, a DNS infrastructure and security provider. The yearly report, based on data from some 30 billion daily DNS queries, found that 23 percent of business users block Facebook, 13 percent restrict reaching MySpace and 12 percent ban access to YouTube. Meanwhile, the OpenDNS-run PhishTank database found that PayPal (46 percent) overwhelmingly is the most phished brand, based on verified fraudulent sites. Facebook came in second, with 5 percent of reported phishing sites trying to mimic the popular social networking brand. – DK
