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...)
ETA
People have asked about the second example. In a nutshell, Ancestry purchased Find-A-Grave in 2013, and Blackstone acquired Ancestry in 2020.
Originally, Find a Grave was basically used by amateur genealogists to check the names and dates on gravestones across North America. So, if you want to verify Grandma Smith's burial location and other gravestone data three states away, you could search the database for free. Volunteers could submit photos and other data.
Blackstone brought in a Facebook executive to run its genealogy business, and gamified Find A Grave for engagement/revenue purposes (Find A Grave is top of funnel for Ancestry subscriptions and also is heavily blanketed in ad networks.)
Gamification led to some very ugly situations, and as I recall they barely backed down over this. Per Roberta Estes, an experienced genealogist cited above:
The problem is that finding your loved one’s memorial, often with incorrect information, created by a stranger is unexpectedly jarring, at best. Especially to discover that your family member was only a trophy harvest whose memorial was created hours after they died. Then, having to ask (sometimes beg an unresponsive person) for the transfer of their memorial to you, only to have the creator’s name forever associated with the memorial adds insult to injury. ...
Who in their right mind would think that entering those massacred children into Find a Grave immediately was acceptable by any criteria? Any standards of decency? And why would Find a Grave tolerate this for even a minute? Death is traumatic for family members under the “best” of circumstances and it only goes downhill from there.

The second one is... Ancestry? They're Blackstoning Ancestry.by tptacek

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.by ilamont

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.by tptacek

> somewhere high atop 345 Park Avenue a Blackstone executive is twirling his mustache while saying "gamify the gravesites".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.

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 angleby bearsyankees
8/24/2026 at 8:27:22 PM
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 stuffby bearsyankees
8/24/2026 at 7:22:02 PM
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.by dylan604

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.by tptacek
8/24/2026 at 5:05:06 PM
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 ]by bearsyankees
8/24/2026 at 5:13:30 PM
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.by tptacek

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.by tptacek

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.by tptacek
8/24/2026 at 7:59:18 PM
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.by tmnvix
8/24/2026 at 8:02:34 PM
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.by tptacek
8/24/2026 at 8:30:06 PM
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.

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.by tptacek

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.

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?

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.
