HANOI - Around 76 percent of Vietnamese internet protocol (IP) cameras are susceptible to illegal access because users keep the fixed accounts of the makers rather than changing them, according to a report by local internet security firm BKAV on Monday.

As fixed accounts of IP cameras have been popularized, camera providers have not warned their customers about the threat of malware and have not guided customers to change accounts and passwords, local Vietnam News quoted network security experts as saying.

"Users should change IP camera accounts and passwords immediately when they install them or they can turn off the remote access function if it is not necessary," a BKAV expert said.

The report also said during the third quarter this year, there were 7,000 trojan attacks, which included harmful code to steal information, or 35 percent of malware for mobile phone appearing every day. The figure has doubled from the same period last year, which was at around 18 percent.

"The strong increase of trojan brings a huge benefit for hackers because they can steal money from banking accounts or cheating and blackmail," the expert added.

To avoid such risks, all mobile phone users are warned to be cautious while installing a new application and equip security software for their phones.
