Yeah I’ll have to deal with it at some point one way or another. I’m sure I will close the account at the first opportunity but it’s impossible to find a non-shitty bank or CU. It’s not something I can do at the drop of a hat. It seems not a single bank or CU targets the market of consumers who have some self-respect and a bit of street wisdom.

Why are you so bothered by your bank sending you an email using extremely common informatics technology,

I don’t give a shit how popular tracker pixels are. It doesn’t justify them being in my comms, so I have a duty to not trigger them and I’m happy to treat pushers of these trackers as adversaries and threat actors. They are being dishonest and sneaky. The honest thing to do is to follow the RFC on return receipts, which is transparent and gives the customer appropriate control over their own disclosures.

especially after you already planned for this and literally aren’t sending them any of the data you’re concerned about?

I use a text mail client for other reasons but incidentally it’s good for avoiding tracker pixels. Actually I have to check on something… I not 100% that spamassassin does not trigger tracker pixels. SA has some vulns, like the DNS leak vuln. But if SA does not trigger the tracker pixels, then indeed I’m secure enough.

I did not think of the marketing angle – although even then, knowing the times that each individual opens their mail and their location has value for personalized marketing.

We are talking about banks in the case at hand. It’s unclear how many people have not come to the realization that bankers are now doing the job of cops. KYC/AML. In this particular sector, anonymization is unlikely. Banks have no limits on their snooping. They have a blank check and no consequences for overcollection. No restraint. When they get breached, they just sign people up for credit monitoring and any overcollection has the immunity of KYC law.

At best, perhaps a marketing division would choose some canned bulk mailing service which happens to give them low resolution on engagement. But even that’s a stretch because anyone in the marketing business also wants to market their own service as making the most of data collection.

No that’s not it. My address is unique to the bank, full headers & path match up with other mail from them, and the means to reach them back correct (yes I examine every character for imposters using od -c).

Can you explain why they would want to anonymise the tracker pixels? Doesn’t that defeat the purpose?

Yeah I’m with you… it was more of an attempt at humor. Although if you search around it’s actually common for people to ask how to check if their spouse is on dating sites… which may be inspired by the whole Ashley Madison databreach.

Does pdfinfo give any indication of the application used to create the document?

Oracle Documaker PDF Driver
PDF version: 1.3

If it chokes on the Java bit up front, can you extract just the PDF from the file and look at that?

Not sure how to do that but I did just try pdfimages -all which was not useful since it’s a vector PDF. pdfdetach -list shows 0 attachments. It just occurred to me that pdftocairo could be useful as far as a CLI way to neuter the doc and make it useable, but that’s a kind of a lossy meat-grinder option that doesn’t help with analysis.

You might also dig through the PDF a bit using Dider Stevens 's Tools,

Thanks for the tip. I might have to look into that. No readme… I guess this is a /use the source, Luke/ scenario. (edit: found this).

I appreciate all the tips. I might be tempted to dig into some of those options.

Your assertion that the document is malicious without any evidence is what I’m concerned about.

I did not assert malice. I asked questions. I’m open to evidence proving or disproving malice.

At some point you have to decide to trust someone. The comment above gave you reason to trust that the document was in a standard, non-malicious format. But you outright rejected their advice in a hostile tone. You base your hostility on a youtube video.

There was too much uncertainty there to inspire trust. Getoffmylan had no idea why the data was organised as serialised java.

You should read the essay “on trusting trust” and then make a decision on whether you are going to participate in digital society or live under a bridge with a tinfoil hat.

I’ll need a more direct reference because that phrase gives copious references. Do you mean this study? Judging from the abstract:

To what extent should one trust a statement that a program is free of Trojan horses? Perhaps it is more important to trust the people who wrote the software.

I seem to have received software pretending to be a document. Trust would naturally not be a sensible reaction to that. In the infosec discipline we would be incompetent fools to loosely trust whatever comes at us. We make it a point to avoid trust and when trust cannot be avoided we seek justfiication for trust. We have a zero-trust principle. We also have the rule of leaste privilige which means not to extend trust/permissions where it’s not necessary for the mission. Why would I trust a PDF when I can take steps to access the PDF in a way that does not need excessive trust?

The masses (security naive folks) operate in the reverse-- they trust by default and look for reasons to distrust. That’s not wise.

In Canada, and elsewhere, insurance companies know everything about you before you even apply, and it’s likely true elsewhere too.

When you move, how do they find out if you don’t tell them? Tracking would be one way.

Privacy is about control. When you call it paranoia, the concept of agency has escaped you. If you have privacy, you can choose what you disclose. What would be good rationale for giving up control?

Even if they don’t have personally identifiable information, you’ll be in a data bucket with your neighbours, with risk profiles based on neighbourhood, items being insuring, claim rates for people with similar profiles, etc. Very likely every interaction you have with them has been going into a LLM even prior to the advent of ChatGPT, and they will have scored those interactions against a model.

If we assume that’s true, what do you gain by giving them more solid data to reinforce surreptitious snooping? You can’t control everything but It’s not in your interest to sacrifice control for nothing.

But what you will end up doing instead is triggering fraudulent behaviour flags. There’s something called “address fraud”, where people go out of their way to disguise their location, because some lower risk address has better rates or whatever.

Indeed for some types of insurance policies the insurer has a legitimate need to know where you reside. But that’s the insurer’s problem. This does not rationalize a consumer who recklessly feeds surreptitious surveillance. Street wise consumers protect themselves of surveillance. Of course they can (and should) disclose their new address if they move via proper channels.

Why? Because someone might take a vacation somewhere and interact from another state. How long is a vacation? It’s for the consumer to declare where they intend to live, e.g. via “declaration of domicile”. Insurance companies will harrass people if their intel has an inconsistency. Where is that trust you were talking about? There is no reciprocity here.

When you do everything you can to scrub your location, this itself is a signal that you are operating as a highly paranoid individual and that might put you in a bucket.

Sure, you could end up in that bucket if you are in a strong minority of street wise consumers. If the insurer wants to waste their time chasing false positives, the time waste is on them. I would rather laugh at that than join the street unwise club that makes the street wise consumers stand out more.

It’s interesting to note that some research “discovered thousands of vulnerabilities in 693 banking apps, which indicates these apps are not as secure as we expected.”

Don’t Canadian insurance companies want to know where their customers are? Or are the Canadian privacy safeguards good on this?

In the US, Europe (despite the GDPR), and other places, banks and insurance companies snoop on their customers to track their whereabouts as a normal common way of doing business. They insert surreptitious tracker pixels in email to not only track the fact that you read their msg but also when you read the msg and your IP (which gives whereabouts). If they suspect you are not where they expect you to be, they take action. They modify your policy. It’s perfectly legal in the US to use sneaky underhanded tracking techniques rather than the transparent mechanism described in RFC 2298. If your suppliers are using RFC 2298 and not involuntary tracking mechanisms, lucky you.

You’re kind of freaking out about nothing.

I highly recommend Youtube video l6eaiBIQH8k, if you can track it down. You seem to have no general idea about PDF security problems.

And I’m not sure why an application would output a pdf this way. But there’s nothing harmful going on.

If you can’t explain it, then you don’t understand it. Thus you don’t have answers.

It’s a bad practice to just open a PDF you did not produce without safeguards. Shame on me for doing it… I got sloppy but it won’t happen again.

Not sure if this is relevant, but service manuals for cars older than 2014 can be found here: charm.li (no cost and enshification-free).

Also worth noting Brother uses that trick where empty cartridges are detected by a laser which is exactly not positioned as low on the cartridge as it could be, forcing people to toss not-so-empty cartridges.

BTW, regarding the trackers dots I’ll drop a link here for anyone who wants to verify Brother’s role in it:

https://www.eff.org/pages/list-printers-which-do-or-do-not-display-tracking-dots

Another reason to use inkjets: GHG footprint. Inkjets use far less energy than lasers. It’s a shame we have to choose between ecocide and tricks and traps.

The only no-compromise path I see is to pull an inkjet from the dumpster, fix it, and refill the cartridges with homemade “ink” from spent coffee grounds and tea.

I should also add that some people come for asylum but they do not follow the legal process because they are reasonably concerned that the process will fail to protect them (especially if they entered under the Trump regime). If someone enters without filing then gets targeted (e.g. a hospital rats them out), and only then claim asylum, I don’t know what happens but obviously we need the process is competent about separating the genuine cases from the rest. I suppose that’s the scenario you are referring to.

Asylum is a legal process. If they follow that process (which begins with claiming asylum), then of course they cease to be illegal immigrants throughout the process.

In fact, borderline human rights compromise is actually a good incentive for people to leave. Would perhaps be good for the country if those in Texas who respect human rights would move from Texas to Pennsylvania for a human rights upgrade (where also the death penalty was repealed).

But I doubt your statement is accurate considering inbound refugees are fleeing from even worse conditions w.r.t. human rights. Refugees still technically have their human right to access emergency medical treatment, they just risk getting harassed and tagged for deportation.

A month ago you would have been wrong. But indeed apparently this just changed:

Question answered in the parent thread:

https://lemmy.sdf.org/comment/15364720

when a server pushes a 403, it still sees the full URL that was attempted.

That’s interesting. It sounds like browsers could be designed smarter. I get “403 Forbidden” chronically in the normal course of web browsing. In principle if a server is going to refuse to serve me, then I want to give the server as little as possible. Shouldn’t Tor browser attempt to reach the landing page of the host first just to check the headers for a 403, then if no 403 proceed to the full URL?
