A group of people have tried to hack into the Defence Ministry's website in a symbolic protest against the amended Computer Crime Act, but the attacks did not cause much damage, said defence spokesman Kongcheep Tantrawanich on Monday.
Maj Gen Kongcheep called for the group to stop doing so as it could cause damage to government agencies, as well as the country as a whole. He did not give details of the attacks.
An error is reported when trying to access the Defence Ministry website at 2.30pm on Monday.
As of 2.30pm on Monday, an attempt to access the website by the Bangkok Post failed with "The following page has become unresponsive" error. It came online eight minutes later.
He said it was pointless for Thai people to cause damage to the country only because they lacked proper understanding of the computer crime law.
The junta-appointed lawmakers passed the bill in a unanimous vote on Friday amid heavy protests by several internet users' groups, some of which have continued with the demonstrations.
Hacking into government website is not a way of dealing with the problem, he added.
According to Maj Gen Kongcheep, a group of people on Sunday tried to hack into the Defence Ministry's website but failed because the ministry has a defence system.
"All armed forces are well-prepared to cope with this problem. The attempts only served to make us more vigilant. As for a report that foreign hackers have also joined the attacks, I would like to remind them that doing so is unlawful. Attacks on the financial, banking, transport and other systems will cause damage to all Thais," he said.
Maj Gen Kongcheep said concerned agencies should also try to promote understanding with people that the computer crime law was not a single gateway policy.
On the announcement by the Citizens Against Single Gateway group to attack government websites from Dec 20, Maj Gen Kongcheep said they should not do that. He added he was confident all government agencies had an effective defence system of their own.
