Kiwi Bank and ANZ, as well as New Zealand Post, Inland Revenue and MetService, experienced a blackout due to a cyber attack earlier today.
Cyber attacker Numerous New Zealand websites and services were shut down today. In which an integrated hit appears.
Kiwi Bank and ANZ customers also reported internet banking problems and the closure of their accounts.
And the government’s computer emergency response team, CERT NZ, confirmed that it was monitoring several denials of service attacks.
Dave Perry, an AUT professor of computer science, said the attacks were similar to those of those who damaged businesses this year.
“It’s very similar to the attacks that took place earlier this year. Effectively, what is happening is that the attackers are probably setting up a lot of criminal gangs because they are called computers that They are controlled by putting viruses in them and all over the world.
“They are basically hitting these websites with a lot of requests, so much so that the websites can’t compete with it and then they can’t provide service to anyone and effectively what is happening is this “They are attacking you. They are asking for ransom.”
While some may expect security measures from banks, Perry says the attacks have put banks in a precarious position.
The problem is that what has happened in this situation is that the way you defend against these attacks is to effectively identify that the requests are somehow suspicious … now they will but They don’t even want to stop legitimate requests.
“So, especially for banks, they are in a very difficult position because of course people want to do the transaction and you don’t want to stop the transaction because the bank suddenly says halfway through your transaction that I’m fine with you. I’m not sure about the computer, maybe I’ll block you for a while.
“Banks have found a very delicate balance process and what often happens in this situation is that banks deliberately reduce the amount of service provided on the Internet in order to better manage it.”
Perry says the banks’ response does not indicate that they are failing to do their job, but rather that they are careful to reduce the amount of transactions affected.
He says criminal gangs will be aware that New Zealand is in a lockdown and could provide further impetus to the attack.
“Certainly this kind of thing is happening, these people are constantly monitoring security vulnerabilities and there are also incidents that could lead people to become more vulnerable.”
“The Internet is going to be used more anywhere in the lockdown, so if you’re doing this kind of thing, this is a good time to attack.”
Many people around the world are working from home because of the Covid 19 epidemic, Perry said, adding that cyber security measures are more likely to slip and allow attackers to hijack more computers. Is.
“Honestly, I think in a coveted world where a lot of people are working from home security they go down … people share computers, use Wi-Fi which is local and they do all sorts of things. Do
“I think maybe there’s an effect in some places where computers are being hijacked to attack, most of them because of cowardice and because more people are working from home. Are. “
Perry says many of the cyber attacks are coming from US-based computers whose groups are carrying out attacks from abroad to target places like New Zealand.
