Bkav recorded an average of 30 cases of scams via Yahoo Messenger per month during 2011. In several cases, the number of victims mounted to dozens of pepple.
Facebook has also become a useful tool for hackers. During the last days of 2011, Bkav detected the first viruses spread by Facebook chat.
Last year, Vietnam also saw a large number of websites hacked. Over 85,000 of computers nationwide have been been attacked by the Ramnit virus, which enables hackers to take important information from victims' computers.
In 2012, together with the boom in the number of smartphone users, the country may experience the fast development of viruses on mobile phones, Bkav added.
