For some reason, I found myself going down a Christopher Lee rabbit hole over the past couple of weeks

Did you know that he made multiple metal albums/EPs including "A Heavy Metal Christmas" and "A Heavy Metal Christmas Too"?

A bit of a follow-up on the claim that an anonymous tip was received by the Office of the Privacy Commissioner regarding PII leakage 6 months ago.

While I don't have access to either the email or the anonymous report, I think I have a general understanding of where this has all come from.

Just a friendly reminder that if you find yourself building website functionality that allows users to upload files (such as say; health documents), please don't blindly trust the file extension provided by the user 🙃

I'd be curious to hear from anyone who does use Proton Mail on how the experience is?

If it's E2EE, I take it that just the message body is encrypted and not the headers to allow for evaluating message rule filters etc?

How does spam/phishing detection work if the message body is encrypted? 🤔

A useful article on how ManageMyHealth and other patient portals came to exist (just ignore the error of the first 8 words).

How did a small NZ company become the country's biggest patient portal provider? And whose job is it to make sure private companies keep your health data safe?

Heather also wrote a book that may cover a lot of the same ground, if not new ground! I dunno but I'm gonna have a read of this too.

Means of Control by Byron Tau is a really good book if you want to learn more about the ads-to-government pipeline, especially when it was operating at its peak back in the early to mid 2010s

This cannot be stressed enough, from the 404 piece yesterday: ICE is working from a legal rationale which states that if a device is collecting adtech or location data, which is then sold to ICE, b/c the owner didn't change the privacy settings, the owner relinquished their Fourth Amendment rights.

Since a breaking news banner has been put up, I'll point out that this appears to be a recap of the original Blackveil article from January 1st. While they are valid issues, I'm not sure that they rise to the level of a banner.

Sai reminded me of 2019 revelation of #DataBreach of Tū Ora Compass Health where up to 1M NZers' medical data was exposed in cyber attacks dating back to 2016 or earlier. What did #HealthNZ and PHOs learn from this? What should they have done? @utf9k.net

Just found out that someone I know whose records are *extremely* sensitive was one of the victims. What a disgrace.
Confirmed today that my stuff is still there on Manage My Health, even though my GP practice shifted to TheDoctors nearly a year ago. The whole thing is so sloppy. I did have to compulsorily change my password first. Like my bloody password was the actual problem.
"MMH has offloaded responsibility of deleting their old accounts onto the patients but many people get signed up to such portals by their GPs switching to the platform. It should not be patients’ responsibility to delete accounts if they did not individually get into a contract with the platform"

I will be sleeping in tomorrow and I will be surprised if I wake up to any news
Hmm, I wonder if the ransom has been paid.

I overlooked it given all the new articles about Kazu that popped up this morning but they had taken down the various posts about MMH in their channel as well as the Tor ransom page.

Then hacker comes in, with a stolen ticket. And then they ask for every coat on the rack. The instruction was "only give coats to people with tickets". Hacker has ticket. So, they give them all the coats.

The stolen ticket is not the issue here. It's that the instruction missed a crucial qualifier.

The API is like the person at the coat check. There's a big rack of coats behind them, and they've been instructed to "only give coats to people with tickets".

No ticket? No coat. This is good! Someone comes with ticket, askes for a coat. They get their coat. This is good!

I really want to make sure that I do right by ManageMyHealth so I've taken the most generous interpretation of the injunction that I can to help them out :)

After discussing this further with the Ministry of Health via direct email, they've confirmed that "this matter is within the Ministry's purview" and have reversed the transfer.
If you recall the 2024 OIA that was asking for audit findings from Te Whatu Ora on ManageMyHealth, Te Whatu Ora said they were aware of MoH having done reviews but didn't have access.

I filed an OIA with MoH who just said they're transferring it back to Te Whatu Ora 🤦
