First Malicious MCP in the Wild: The Postmark Backdoor Stealing Your Emails

Bait article with an awful chatgpt generated image at the top to boot.
nativeit•1h ago
How is it “bait”? It’s covering a fairly brazen supply chain attack, what were you expecting?
bonsai_spool•1h ago
Perhaps not something displaying every hallmark of an AI-generated article.
oasisbob•19m ago
That's not a popular opinion to express these days.

If you point out the excessive length, the rhetorical flaws, and the obvious idiomatic tics of AI writing people don't tend to want to hear it.

When authors had to do the work, you'd notice your article approaching 1900 words and feel the natural need to cut redundant platitudes like this:

> The postmark-mcp backdoor isn't just about one malicious developer or 1,500 weekly compromised installations. It's a warning shot about the MCP ecosystem itself.

An AI feels no such need, and will happily drag their readers through a tiresome circuitous journey.

The new Outlook app keeps a copy of all your e-mails, including your e-mail credentials, at Microsoft servers. Microsoft is doing this for months to millions of people and nobody cares. Why a single developer copying a couple hundreds of e-mails is such a big deal?

Microsoft Servers != Malicious Actors Computer
aleph_minus_one•1h ago
> Microsoft Servers != Malicious Actors Computer

Whether this statement does hold or not depends a lot on your personal worldview:

- How do you define "malicious"?

- Is Microsoft a malicious [in the sense of your previous answer] actor (or not)?

- What is the result of your risk assessment that Microsoft will become a malicious in the future?

OtherShrezzing•52m ago
Put simply, to Microsoft, my company’s continued business is worth more to them than my company’s nefariously-gotten email are.

The chance that they become a hostile actor to my business is effectively zero. Certainly among the lowest chances of any email provider.

aleph_minus_one•37m ago
> The chance that they become a hostile actor to my business is effectively zero.

I guess the same holds for this malicious (?) single developer.

anonym29•10m ago
You choosing not to care about Microsoft's extensive and well-documented history of adversarially abusing, misleading, lying to, spying on, harassing, and stripping control away from their own end users doesn't mean Microsoft isn't malicious.

Microsoft sees and treats their end users simultaneously as adversaries, as incompetent children, and as data cows to be milked without genuine informed consent for Microsoft's own profit, not as customers deserving of respect, dignity, and autonomy.

Good thing i dont even wanna use any 3rd party libraries when using stuff like Postmark. Just old fashioned curl and POST requests to send emails with Postmark.

And i consider myself a lazy person. Using 3rd party libraries are just more of a headache and time sink sometimes

thepill•1h ago
I understand the problem mentioned with mcp servers but this kind of attack could happen to any external dependency (like a smtp package) i guess
WD-42•12m ago
The difference is if you went looking for a smtp package you’d land on an established library with a track record and probably years worth of trust behind it. The Mcp stuff is so new all of that is missing, people are just using stuff that appeared yesterday. It’s the Wild West, you need to have your six shooter ready.
jinwoo68•1h ago
It's almost always npm packages. I know that's because npm is the most widely used package system and most motivating one for attackers. But still bad taste in my mouth.
hendersoon•1h ago
This is why I don't run stdio MCP servers. All MCPs run on docker containers on a separate VM host on an untrusted VLAN and I connect to them via SSE.

Still vulnerable to prompt injection of course, but I don't connect LMs to my main browser profile, email, or cloud accounts either. Nothing sensitive.

iagooar•54m ago
Even OpenAI uses npm to distribute their Codex CLI tool, which is built in Rust. Which is absurd to me, but I guess the alternatives are less convenient.
tonyhart7•22m ago
nah bro you got it wrong

its the other way around, codex started with TS then rewrite it to rust

Here is hoping the above comment isn't upvoted to the point where it is portrayed as something like a "key takeaway" from the article. That would be missing the point.

> Somehow, we've all just accepted that it's totally normal to install tools from random strangers that can

Some people do this without thinking much about it. Not all of us. This is not normal nor ok.

Predicting this kind of attack was easy. Many of us probably did. (I did.) This doesn't make me feel much better though, since (a) I don't relish when lazy or ignorant people get pwned; (b) there are downstream effects on uninvolved people; and (c) there are classes of attacks that are not obvious to you or me.

Stay suspicious, stay safe. There are sharks in the water. With frikin' laser beams on their heads too.

mattxxx•40m ago
It's pretty daring to do something like this. Something so brazen has a 100% chance of getting caught given enough time...

That said, installing any package is a liability, whether it's a library or an mcp server.

xpe•25m ago
Perhaps. Or perhaps not. What are the likely consequences when this happens? Plausible deniability might work here -- and it might even be true.
Dilettante_•21m ago
>Well, here's the thing not enough people talk about: we're giving these tools god-mode permissions. Tools built by people we've never met. People we have zero way to vet. And our AI assistants? We just... trust them. Completely.

I keep seeing this pattern in articles: "Did you know that if you point the gun at your foot and pull the trigger, yOu ShOoT yOuRsElF iN tHe FoOt??!? I couldn't believe it myself!! What a discovery!!1!"

Are people really this oblivious or are these articles written about non-issues just to have written 'content'?

BobbyTables2•18m ago
These also remind me on the early 1980s mentality of some who thought anything printed by a computer must be correct.

It’s an AI, it must be perfect! /s

avs733•16m ago
This is unfair. It presumes a universal understanding of something largely because it is obvious to us. Most computer users have little to know detailed understanding of how any computer technology works, and because they are invisible and abstract, even less understanding of the risks they expose themselves to.

The answer to you gun analogy is false because it assumes basic knowledge of a gun. This is part of why so many kids shoot themselves or family members with guns - because they don’t know if you pull the trigger something violent will happen until they are taught it.

lazide•13m ago
Did you know that if you give a loaded gun to a chimpanzee, sometimes it will shoot you (or itself) and it didn’t even know that was going to happen?!? Even if you tell it several times?!?

And that if that happens ‘smart’ people will tell you that it was really dumb to do that!!?!

ljm•6m ago
What’s obvious to the audience of HN isn’t necessarily obvious to anyone else.

Articles like this are intended to serve the latter group of people.

And it’s true, AI agents with MCP servers are pretty much unsafe by design, because security was never considered from the start. Until that changes, if it ever even does, the best thing to do is to inform.
