HA NOI — Internet security company BKAV warned administrators of several major Vietnamese websites yesterday that their sites might be infected with malicious software.
When opened by Chrome and Firefox browsers, a number of leading websites such as vff.org.vn (Viet Nam Football Federation) and other sites ending with gov.vn (government websites) were found to be infected with malware.
"The problem initially happened in 2008 but suddenly came back in recent days. These websites have now been placed on Google's blacklist," said BKAV's director of internet security, Nguyen Minh Duc.
Duc said that for Chrome and Firefox users, the safe browsing function would check if a given site was on the blacklist or not. If it is, the browser will ask the user to leave the site, he added.
"Web administrators should check if their websites really contain malware, and if so, should clean it from the server," he said.
He said after removing any hidden malware, administrators can go to google.com/webmaster/tools to remove the sites from the blacklist.
Meanwhile, Internet users should contact web administrators if they got a warning from Google about a particular site, Duc added.
Ha Noi-based BKAV warned the public earlier this month that a critical flaw in Remote Desktop Protocol (RDP) across supported versions of Windows affects about 32 per cent of the Vietnamese Government web servers. — VNS
