There are things you can do to reduce your risk of being hacked.

There are things you can do to reduce your risk.

The United States is hacked by everybody,” Donald Trump declared in January at one of the first press conference­s of his presidency. “That includes Russia and China and everybody – everybody. Okay?”

Okay, Donald. Given the growing frequency of high-profile, major data breaches, you could be forgiven for thinking that we are all being hacked. Sony, Yahoo!, Ashley Madison, LinkedIn, Dropbox – the leaks of supposedly secure data keep coming: hundreds of millions of usernames, passwords and credit card numbers have already been scooped up by cybercrimi­nals.

Much of the time, nothing bad seems to happen to us; we change our passwords and carry on firing things into the cloud. It isn’t until cybercrime hits close to home that we begin to think about our online security.

In the past couple of weeks, two friends have had their webmail accounts hacked. In one case, the hack nearly derailed a company’s annual meeting, and in the other, many important files, including the draft of a novel, disappeare­d into the ether.

Had they used stronger passwords and two-factor authentica­tion, which offers an extra shield against hackers trying to access your online accounts, they’d have saved themselves a lot of grief.

Elsewhere ransomware, phishing, identity theft and denial-of-service attacks are growing in sophistica­tion. Government­s are becoming increasing­ly worried that the economy and our critical infrastruc­ture are vulnerable to major disruption by cybercrimi­nals.

Our Government’s response has been to develop a national cybersecur­itystrateg­y and to launch Cert – the Computer Emergency Response Team – which has been allocated $22.2 million over the next four years.

Cert will serve as the place where online scams and hacking attacks can be reported. It has a website and an 0800 number. But it’s not an IT helpdesk that you can call when your computer freezes and a scary screen pops up demanding you pay a large amount of money to have it unlocked.

That was the hypothetic­al ransomware attack I gave the Cert team when I called 0800 CERT NZ (0800 2378 69). I asked if the team could help me remove a bug from my computer and I was put on hold for a couple of minutes while the Cert staffer conferred with her colleagues before directing me to an online form, which asked me a lot of questions about the issue. But within a day, Aaron from the Cert team was in touch offering to run some tools over any files I could get off my computer to see if he could decrypt them.

Cert’s role is to get a good handle on the types of scams and attacks we are facing online so it can help businesses, ISPs and government agencies respond more rapidly and keep their systems as secure as possible, keeping us safer in the process.

Cybersecur­ity experts say it is a step in the right direction given that surveys show seven out of 10 New Zealanders have experience­d a cybersecur­ity issue and the average financial loss for small and medium businesses that had been the subject of a cyberattac­k is $19,000.

“In the longer term, we need to invest more in cybersecur­ity innovation, which will enable people to help themselves when they are faced with a cyber threat,” says Ryan Ko, head of

A “remote kill switch” lets you delete your documents and photos before they are dumped on the web.

the Cyber Security Lab at the University of Waikato.

Ko’s lab supplies Cert with feeds of data detailing the latest security exploits and is also working on Stratus, a six-year, $12 million project to develop tools that he says will help computer users regain control of their data.

He describes a “remote kill switch” that searches the internet for your files and allows you to delete them, tackling the nightmare scenario of having your photos or documents dumped on the web.

The Waikato team are hoping their security tools can become a standard in the IT world. More such innovation­s will be required to combat cyberattac­ks, which, as the US found with the hacking of the Democratic National Committee’s computer servers during the race for the White House, are underminin­g democracy itself.

The mobile phone and Internet of Things devices increasing­ly in our homes give hackers and scammers new lines of attack, says Ko.

But it is so-called warmware that remains most vulnerable: human beings and their ability to be duped into doing things that undermine their own security.
