Should it be illegal to pay ransomware in NZ?

So, will cutting off payments stop their attacks by removing the incentive?

These criminals are smart and highly motivated. They seem to have no conscience but plenty of greed. Waikato is not only the hospital being brought down – there was a huge wave of hospital attacks in the US in October, just a few months ago – Several hospitals targeted in new wave of ransomware attacks – CNNPolitics.

I don’t know how Waikato DHB got infected, but the rumour is that it was from phishing attacks onto machines that weren’t fully patched up to date. We don’t know if that is true, but it is a common attack vector. Once a hacker gets into a system, they often hold back and try to dig further looking for more vulnerabilities they can exploit. The more damage they can cause, the more ransom they can demand, so they will often use one vulnerability to find the next, and so on until they finally have enough to bring the house down.

Security is all about layers. There is NO way to prevent attacks, and it is impossible to guarantee that any system is invulnerable. We saw that with the recent Hafnium attack where a vulnerability was exploited before patches were available to block it. But the more layers of security, the harder you make it, and you reduce the scope of any harm.

Today, even if you have the best backups and can recover the system, the hackers then threaten to release the data you hold to media or competitors. In the case of the Waikato DHB, it is being reported that personal data is being released to media by the hackers to increase pressure, even as they fail to stand their systems up.

As to paying the ransom, I suspect your perspective changes when your business, your job or livelihood is threatened.  Not an easy decision and hopefully one we can avoid by being paranoid.

The best solution we can recommend is to check your cyber insurance and to apply the best security you can reasonably afford, which should be more than you had last year. Expect it to be more again next year as new tools and new threats emerge.  Consider managed security solutions like our KARE for Security and more advanced KARE for Security S2 plans.

We don’t know where this will end, or if it will end, but let’s hope so. It is such a drain on our resources and holds us back from investing in tools that make us more productive.
