Beam Living is just the property management company that runs buildings Blackstone owns in New York City. There are thousands of companies like this all over the country and if you poke hard at any of them you will find stuff like this.

There's nothing wrong with pitching stories this way, but for context, if you look at this researcher's archive, they're all basically "I found a vulnerability in some big company's thingy". The news hook here is literally just "I found a GraphQL bug". This is not Alex Schapiro's most interesting front-page story (by which I mean: they've posted some genuinely interesting stuff before).

Well, the other notable fact about this story is it's Blackstone, which has a record of giving managers a lot of leeway to do anything to juice the numbers.

Two examples:

1) Hiring 14 year old slaughterhouse workers (https://www.nbcnews.com/news/us-news/pssi-hired-same-child-t...)

2) Gamifying of one its genealogy websites that tracked cemetery markers, which resulted in people "claiming" victims of mass shootings for points (https://dna-explained.com/2022/06/02/find-a-grave-owned-by-a...)

Geez... Item 2 could be its own HN post.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @04:47PM (#49425620)
The second one is... Ancestry? They're Blackstoning Ancestry.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by ilamont on Monday August 24, 2026 @04:52PM (#49425702)
It's Find-a-Grave, an indie genealogy site that was acquired by Ancestry, which itself was acquired by Blackstone sometime in the last decade. Blackstone brought in an ex-Facebook executive to run it, and this was one of the results.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @04:55PM (#49425721)
Right so the premise here is that somewhere high atop 345 Park Avenue a Blackstone executive is twirling his mustache while saying "gamify the gravesites". Seems implausible. Ancestry was not a good company to begin with (you know what organization really does a good job of this, by the way? The Latter Day Saints), and this is fully on brand for them.

I don't think so.

It's more like "hit the numbers no matter what, we don't care what you do to hit them." They hire managers that are ruthless about following through. IMHO this style of ownership is more likely to lead to otherwise avoidable situations involving lax security, teenaged slaughterhouse workers, and trophy hunters on genealogy sites.

Well yeah, pretty much?

Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Tuesday August 25, 2026 @11:22PM (#49443860)
My problem here isn't Blackstone (unless we're talking about housing, where anti-Blackstone slopulism will set me off, because I'm a housing activist, IDGAF about PE), it's that people have a weirdly high opinion of pre-change-of-control Ancestry.com. Ancestry is terrible! This is all highly on brand for Ancestry, the Experts Exchange of geneology.

Also, as far as I know, no residents were ever alerted that their data was exposed so this also is a bit of a public disclosure angle
Re:A Blackstone real estate company exposed SSN digits, DOBs... by ldoughty on Monday August 24, 2026 @04:27PM (#49425408)
It has to be 18 months after public disclosure before the company has to send out a letter letting them know that someone might use their information, and they are eligible for yet another free credit monitoring service......

/S

Yeah I hear you but I think this community loves writeups like these -- I personally have learned a TON about how to be an effective security researcher by reading technical writeups others have posted here. Agreed this vuln wasn't a complicated one by any means but I feel like this is the forum for sharing this stuff
Re:A Blackstone real estate company exposed SSN digits, DOBs... by dylan604 on Monday August 24, 2026 @03:22PM (#49424635)
But as GP stated, if as a security researcher you discover this as Company X using Company Y's product that has the vuln but your write up lays the blame at Company X's feet leaves a lot to be said about your skillz as a researcher. If you wrote it up as Company Y's product has a vuln and is used in this market by companies like X you'd sound like a much more skilled researcher.

I'm glad HN can be counted on to defend Blackstone's good name.

That's not what I'm doing, but if you want me to, I'll bite, because Blackstone does more for housing than activists do (if you measure housing outcomes in terms of how many people end up housed, as opposed to whether or not the "right" people get to live in the "right" neighborhoods).

I think the expectation on a message board is that you can name drop a big private equity firm and count on voting support for them. Unfortunately for you, I've spent the last 5 years working on rolling back single-family zoning in my municipality, and an alarming amount of that work has involved pushing back on NIMBYs arguing that if we allow housing construction Blackstone (very specifically Blackstone) will just come snap all the real estate up and hoard it.

So I've had some time to marinate in this particular bit of populist rhetoric.

Re:A Blackstone real estate company exposed SSN digits, DOBs... by consensus1 on Monday August 24, 2026 @01:00PM (#49422704)
There absolutely is everything wrong with implicating a company that has no knowledge of and no responsibility for the breach.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @01:03PM (#49422753)
You mean the Blackstone namedrop? I had the same reaction. Beam is an internal division of Blackstone, for whatever that's worth, but I don't think there's a news hook about Blackstone here. This is, like, every property management company everywhere, whether indie or corporate.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by bearsyankees on Monday August 24, 2026 @01:05PM (#49422777)
If this is the case then IMO all the more reason to publicize it -- my SSN shouldn't be exposed just because I applied for a lease [ and we shouldn't just brush that off as something that is a given ]
Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @01:13PM (#49422919)
I mean, that's true, and I'm not saying there's anything misleading about the post, just that this is true of basically all the companies that do this. All I'm saying is that there isn't a meaningful Blackstone hook here.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by antonvs on Monday August 24, 2026 @03:39PM (#49424849)
> this is true of basically all the companies that do this

Evidence?

Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @03:45PM (#49424909)
Just Google "property manager" "data leak".
Re:A Blackstone real estate company exposed SSN digits, DOBs... by antonvs on Monday August 24, 2026 @08:36PM (#49427718)
Sorry, but that's not evidence of "true of basically all the companies that do this". Your vibes are not evidence.

I don't understand what you even think you're getting at. Are you saying we should accept this because all companies are like this? Except not all companies are like this.

The only way this kind of thing ever gets fixed is if it's not considered acceptable. You're essentially arguing that it's acceptable. Why? It's a weird sort of kowtowing to incompetent corporations that I just don't understand. Is it that you work for one of them?

Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @09:00PM (#49427874)
I'm sure it would be enjoyable to find someone to argue with who would take the other side of "vulnerabilities are bad" but I can't be that person for you, sorry.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by antonvs on Tuesday August 25, 2026 @10:29AM (#49434807)
DARVO only works if it's plausible.

You were implicitly defending the existence of this vulnerability by making the unsupported claim that this was "true of basically all the companies that do this." When asked to back up the claim, you deflected.

I'm reminded of the banality of evil. You're not trying to be evil, you're just defending large corporations because you've irrationally concluded from some individual examples you've seen that "everyone does it", and therefore there's nothing that can or should be done about it, including even just mentioning it in a post. That's false, and you're wrong.

Super reasonable comment. Totally see how you got there.

It’s fun to watch people try to back off from their defense of sleazy corporations once they’re called out on it.

If you’re too big to manage your subsidiaries, don’t buy them/build them.

This is no different than blaming the big AI tool because it messed up doing work in your spaghetti codebase - “how else was I supposed to do it?”.

Stay small enough to do business properly.

Yes, this is a ding on the parent company.

How indicative it is of their other companies making the exact same mistakes is a different question.

But I’d expect issues somewhere.

Beam Living manages giant high-rise housing developments in New York City. It's not a mom-and-pop problem space, unless you're for some reason opposed to density.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by DANmode on Monday August 24, 2026 @03:25PM (#49424674)
I’m opposed to using your scale as an excuse to be an incompetent.

It’s one of the major ethical / effectiveness issues with business - especially American business - today.

Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @03:31PM (#49424748)
You'd much rather rent from someone like Beam Living than a mom-and-pop operator that owns a small apartment building. Things will get fixed, and you'll get most of your security deposit back.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by tmnvix on Monday August 24, 2026 @03:59PM (#49425085)
Personally, I've always had a better experience dealing directly with small time landlords than with property managers. For a start, they have been less likely to raise rents at every opportunity. I also prefer when my money goes to someone in my community/local area.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @04:02PM (#49425119)
I've never once gotten a security deposit back from a mom-and-pop landlord without forcing the issue legally, and I did an informal poll of acquaintances last year and we had never even heard of that happening. Unlike mom-and-pops, corporate property managers just do what they say they're going to do.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by tmnvix on Monday August 24, 2026 @04:30PM (#49425440)
That sucks. Maybe it's a cultural thing or due to different regulations (I'm not in North America)?

Anyhow, all else being equal, so long as I am living in a transactional society, I prefer those transactions to be with people I actually know. I like real relationships. So much of the way we are changing as a society seems to be alienating us from each other - I make a point of trying to counter that in my daily life.

Re:A Blackstone real estate company exposed SSN digits, DOBs... by tptacek on Monday August 24, 2026 @04:48PM (#49425636)
Oh, yeah, for sure, I'm making confident assertions exclusively about American rental norms. I have no idea if corporate property management in Europe is better or worse than independent building owners. All I know is that renting is much more normalized there than it is here, where renters are considered a second-class state of residency that one expects to graduate from into full ownership as soon as possible.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by FireBeyond on Monday August 24, 2026 @05:03PM (#49425827)
I have, multiple times, before I bought.

On the flip side, corporate PMs tried billing my friends for damage that was questionable/grasping at best on an apartment they'd told my friends, in writing, that was going to be gutted down to the studs on the expiry of their lease.

The largest corporate PM in my county has this "look how tenant-friendly we are, we won't raise your leases just because we can" all happy and smiley website where they advertise their open listings...

... and a much less advertised site dedicated just to property owners where they "promise to get you the maximum value out of your investment, looking for every opportunity to maximize its income-earning potential (i.e. raise rents at every possible opportunity to the maximum legally allowed), and "ensuring that when you do change tenants, the minimum effort and cost is required" (i.e. bill your previous tenants for as much of their security deposit as possible, while doing as little as possible).

This led to situations where my partner and I saw that the "inspection form" for the apartment we'd left not twenty minutes prior (it was initially meant to be previously) was sitting on the desk of the property manager filled with remarks like "blinds not cleaned, needed professional cleaning", "drywall holes, needed professional repair", "odors, needed remediation, professional cleaning".

In other words, they'd planned ahead to take the deposit, and when our meeting with the PM was rescheduled it pointed out the lie, "Oh, when was this inspection and these repairs all done? In the fifteen minutes since us locking the door and going down the elevator to wait for you in the lobby?" Of course, said PM company also owned, helpfully, a carpet cleaning company, a housecleaning company, and everything else, so you knew they were going to give you a good deal (not).

"Oh... um... oops... that's a mistake, I must have printed off from a template and not tidied it up".

But this is just dueling anecdotes.

Yes.

Bad customer service (intentional and otherwise) comes in all shapes and sizes!

Re:A Blackstone real estate company exposed SSN digits, DOBs... by DANmode on Tuesday August 25, 2026 @01:25AM (#49429415)
I’ve unfortunately battle-tested this thesis.

Mom-and-pop aren’t financially insulated from threat of lawsuits. Or being looked at poorly in public.

Some random LLC in Utah? Good luck.

Re:A Blackstone real estate company exposed SSN digits, DOBs... by jimbo89 on Monday August 24, 2026 @01:10PM (#49422858)
Beam is actually a little bit unique here. They have a spent a lot of money building a lot of custom software that most other property managers just buy off the shelf.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by consensus1 on Monday August 24, 2026 @02:29PM (#49423985)
Yes, that's what I meant, but I thought your comment meant that it was a property management company hired by Blackstone, not an internal division of Blackstone. That changes things completely.
Re:A Blackstone real estate company exposed SSN digits, DOBs... by phkahler on Monday August 24, 2026 @08:06PM (#49427508)
Yeah like why is Blackstone named and not the actual company? Clickbait.
