Ngo Vi Dong, chairman of the Viet Nam Information Security Association (VNISA)' + char(39)+ N' + char(39)+ N' + char(39)+ N's southern branch, said security systems at the majority of 200 businesses inspected in the south were failing to invest enough in anti-hacker software.
"Up to 34 per cent of businesses had their sites hacked in the first six months of this year. Around 38 per cent of them were not aware that they had even been hacked. The figures last year were 28 and 26 per cent respectively," Dong said.
Dong said hackers tended to attack not only information systems and databases of private firms but those of State agencies as well.
He said they used a variety of mean to bypass security measures, such as spyware, adware, software, Trojan horses and key loggers.
"However, half of the businesses inspected had no policies or budgets for information security," he said.
He added that only 10 per cent of inspected firms that had been hacked had reported the matter because they were afraid it would detrimentally affect their image.
Recently, the department in co-ordination with the Ministry of Public Security' + char(39)+ N' + char(39)+ N' + char(39)+ N's Economic Crime Police Bureau, took action against Fibo company for hacking into the Queen Bee company' + char(39)+ N' + char(39)+ N' + char(39)+ N's main server using the so-called distributed denial-of-service (DDOS), which makes a company' + char(39)+ N' + char(39)+ N' + char(39)+ N's data unavailable to intended users, and botnet, which is a hidden programme.
An investigation showed that Fibo had been attacking the company over a long period of time.
Nguyen Duong Vu, the company' + char(39)+ N' + char(39)+ N' + char(39)+ N's director, admitted the offence.
