This morning, Distributed Denial of Secrets published 410 GB of data hacked from TeleMessage, the Israeli firm that makes modified versions of Signal, WhatsApp, Telegram, and WeChat that centrally archive messages. Because the data is sensitive and full of PII, DDoSecrets is only sharing it with journalists and researchers.

There's a lot of background, so here's a quick timeline of events with relevant links:

  • March: Then-national security advisor Mike Waltz invited a journalist into a Signal group where they planned war crimes. This led to Congressional hearings about Trump officials using Signal groups to discuss classified information.
  • May 1: Waltz (the day he was demoted from position of national security advisor) was photographed using TM SGNL, a modified version of Signal made by TeleMessage. He had texts up with Tusli Gabbard, JD Vance, and Marco Rubio.
  • May 3: I published the source code of the TM SGNL to GitHub.
  • May 4: TeleMessage got hacked, which I reported in 404 Media with Joseph Cox.
  • May 5: TeleMessage got hacked again by someone else, as NBC News reported.
  • May 6: I published analysis of the TM SGNL source code, along with some of the hacked data, that prove the TeleMessage lied about its products supporting end-to-end encryption.
  • May 18: I published details about the TeleMessage server's vulnerability in WIRED. TLDR: if anyone on the internet loaded the URL archive.telemessage.com/management/heapdump, they would download a Java heap dump from TeleMessage's archive server, containing plaintext chat logs, among other things.

Now, DDoSecrets has published 410 GB of these TeleMessage heap dumps. Here's the DDoSecrets description of the release:

Thousands of heap dumps taken May 4, 2025 from TeleMessage, which produces software used to archive encrypted messaging apps such as Signal and WhatsApp. The service came to public notice in 2025 when it was reported that former national security adviser Mike Waltz used TeleMessage while communicating with members of the Trump administration, including Vice President JD Vance and Director of National Intelligence Tulsi Gabbard. TeleMessage has been used by the federal government since at least February 2023.

Some of the archived data includes plaintext messages while other portions only include metadata, including sender and recipient information, timestamps, and group names. To facilitate research, Distributed Denial of Secrets has extracted the text from the original heap dumps.

It seems that the SignalGate saga of staggering incompetence is not yet complete. I'm digging into this data right now. It's bonkers.

    So one of their servers had a /heapdump endpoint that publicly served a heap dump of the server? This whole saga is out of control.

    This group didn’t really “publish” anything, though. They’re offering access to journalists through a request form. They’re also not saying how much actual message content they have because the 410GB of heap dumps makes for a bigger headline number.

        This is why Signal is so opposed to third-party apps (or forks) that connect to their service.

        If you want to keep the branding of Signal being the secure app, you need to make sure that all Signal users are actually using a secure version of Signal.

        If an insecure fork (like this one) becomes too popular, most groups will have at least one member using it, and then the security is gone.

              This is a shallow dismissal of an argument that should be given more consideration.

              Sure, this is HN, we know one of the effects of locking the ecosystem and coloring in-system messages differently is to encourage people to be in the ecosystem.

              At the same time, you ALSO need to consider that obviously there will be leaks.

              Malicious/advertising apps will target the new messaging interface to gain more data on their victims, etc.

                Safe encrypted group chat with stangers is an oxymoron.

                Locking down a platform is not an acceptable solution to the above conundrum - it doesn't matter if the user is using an official device/app whatever if they are untrusted. They can always turn around and leak everything you say without any technical measures.

                Should we have no security? No, if you want to color messages differently based on perceived platform, fine. This is just an illustration that no technical measures can replace the fundamental trust necessary in these types of situations.

            Hm, my understanding is that TeleMessage archival works with iMessage in the same way it does with Signal.

            The third-party federation problem is real, but the vulnerability caused by TeleMessage isn't solved by removing federation.

          If your product is a strong brand then that would make total sense.

          I believe the main criticism against Signal is that they should focus on getting widespread traction of secure messaging, and that perhaps the brand can be a relatively distant concern.

              From the Wired article: "The archive server is programmed in Java and is built using Spring Boot, an open source framework for creating Java applications. Spring Boot includes a set of features called Actuator that helps developers monitor and debug their applications. One of these features is the heap dump endpoint,"

              So the heapdumps being available is a Spring Boot feature so it does not appear to be malicious.

              • By flarecoder 2025-05-2014:532 reply

                I'm the original author of the Spring Boot feature for heapdumps: https://github.com/spring-projects/spring-boot/pull/5670.

                It seems that users commonly misconfigure Spring Boot security or ignore it completely. To improve the situation, I made this PR: https://github.com/spring-projects/spring-boot/pull/45624.

                When the PR was created in 2016, endpoints were marked as "sensitive" and, for example, the heapdump endpoint would have to be explicitly enabled. However, Spring Boot has evolved over the years, and only the "shutdown" endpoint was made "restricted" in the later solutions. My recent PR will address that weakness in Spring Boot when users misconfigure or ignore security for a Spring Boot app so that heapdumps won't get exposed by default.

                  In my opinion, the original sin of Spring Boot Actuator is allowing server.port and management.server.port to be the same. It makes it too convenient for developers to skip the security review that would be done for opening a non-standard port.

                  I think it would be wise to either disallow the ports being the same, or if they are the same, only enable the health endpoint.

                    I'm more of the opinion that developers will make smart choices, when motivated.

                    Sure, punching buttons for money is a widespread issue in the industry, but devs also like convenience.

                    Security has the hard problem that it's infuriatingly difficult to troubleshoot (ever tried to write security policies for an app or figure out how to let an app through a firewall, or set of firewalls?), and there's a bit of a culture of "security by obscurity".

                    So it's kind of expected that this is the behavior...

                    Sure some people will really just not care, mistakes will be made, but secure defaults, easy to configure and simple to understand are features not often seen from security products generally. This is driven by poor motivations from security folk who want to protect their industry...

                  Based on [1] it seems like one `management.endpoints.web.exposure.include=*` is enough to expose everything including the heapdump endpoint on the public HTTP API without authentication. It's even there in the docs as an example.

                  Looks like there is a change [2] coming to the `management.endpoint.heapdump.access` default value that would make this harder to expose by accident.

                  Let's look for `env` next...

          But why would they? It's not their job. They have massive IT staff supporting them. "High level U.S. officials" are just executives; the pointy-haired bosses to the pointy-haired boss. Only difference is these wear little decorative pins over their breast pocket.

          Every Fortune 500 company has dedicated IT staff for execs; someone you can call 24/7 and say "my shit's broke" and they respond "we just overnighted you a new phone".

            I think that's a misdirection.

            The narrative is that:

            a) they were using a compromised piece of software

            b) they should not have been using that software - not (necessarily) because it was compromised, but because it wasn't US DoD accredited for that use case.

            (I understand your point that these guys are not tech savvy, and do not need to be, but they should be regulation-savvy (clearly they either are not, or willingly broke those regulations), and they should be following organisational guidelines that presumably cover the selection and use of these tools types.)

              It's not too early to tell, we knew from the beginning that the use of Signal (let alone its clone) was not authorised to be used for such communications.

              Yes, there's a fleet of people who are supposed to make such tech decisions. The people involved specifically went against those rules. The existence of a group chat using an authorised app is a violation on its own, adding a journalist to it is a violation on top of a violation.

              Adding a journalist was accidental, but using such an app (despite it not being approved) is very intentional.

            IT staff that knew it was illegal to provide them tools for a conspiracy were fired or silenced. So the only people left were their cronies, who instantly complied with their illegal request, to the best of the cronies' abilities. For such national failures, the buck has to stop at the very top, not on some IT monkey.

            This is typical for highly corrupt governments and autocracies, they crumble from within because the autocrats can't trust random, competent people so their inner circle becomes saturated with people who are selected on the basis of loyalty not competence, and these people end up making the most important decisions and running the country.

            Would tend to agree with most of that, but I think the assertion is Petey needed to ask his IT leadership to do the due diligence before diving in, not that he needed to decide using his own depth of skills and experience.

            I assume he did and they said it was a bad idea - the memo they'd released a few weeks prior about Signal vulnerabilities seems to suggest a lack of faith in that approach - but he was already banging away on his phone with all the grocery reminders and definitely not battle plans he needs to keep pushing out. Which is also how it feels in the enterprise space these days.

            The fundamental concept of plaintext archiving (escrow) of messages from e2ee messaging apps is insecure by most definitions.

            They could have used user-custody public key cryptography, where the end devices have the pubkey of the customer, and archive only re-encrypted messages to TM that they can’t read.

            That is not, of course, what they did. They just archive them in plaintext.

            • By kevincox 2025-05-2012:08

              I don't think it is. I can archive my own messages and E2E security on the messaging layer means I don't have to trust the operator of the messaging service to not read my messages because they can't. The choice of how I archive the messages is completely orthogonal to the choice of messaging platform security. I could choose to use an E2EE approach if I want but in that case it probably wasn't even desired as the point was to have these be archived for audit purposes. (Of course they are more secure options such as archiving to an audit key, but this is still orthogonal to the concern of the messaging protocol)

      That's very important to say. I went through one of these massive data dumps recently and it was literally all cached operating system package updates and routine logs. Nothing at all of interest.

      It's easy to cut the size on a heap dump. When it's not done it seems sketchy. But it could be a 512GB dump and already pruned, so I could be wrong.

        Most of the the heap dump will be filled with stuff like java.util.String!blahjava.util.ArrayList!

        Though the heap dump would have messages in flight at the time. It's obviously not as useful if you are just trying to grab messages for a specific person.

          Edit: downvote all you want. Israel is still committing a genocide. No hospitals left standing. Killing aid workers, journalists, and doctors. A million people on the brink of starvation. Literally salting the earth to prevent crops from being grown. That is war crimes, ghettoization, and genocide.

        One problem that smart people tend to make is in thinking that being really smart in one area is generalizable to all others. Just because they're good at AppSec doesn't mean they're good at networking or operating a webserver.

          Spooks in general like to project a veneer of competence, downright invincibility. Entertainment media, journalists, experts play a big role in this. And by and large it works.

          It’s especially true for spooks of a certain entity. Also, it’s easy to confuse brazenness, being protected from consequences, and usually downplayed or secret Western complicity with competence.

          I'm not sure about this case, but maybe the assumption here is that these are people from a technical branch of Mossad, such as Unit 8200, which does SIGINT. I've interviewed 3 of them for your typical Big Tech SWE position, and to a candidate, they were very strong engineers. I never got to work with them, however, because they always got better counteroffers...

        From the Wired article, it may not have even been a mistake, depending on the version of Spring Boot.

                Took a while to workout that for some reason docker-compose is messing directly with iptables to shoot holes in the firewall we'd configured. Figured out you have to write your compose in some super special way to disable that functionality. Compose should never ever open network ports, ever in my book - to do so without a warning or anything though is like I said, insane!

        Or intentionally. There could be an APM agent which just lets you run heap dumps any time you want, or they enabled heap-dump-on-crash, or had a heap dump shutdown hook, etc. There's a lot of ways to trigger dumps. If we're talking about a full dump, and the apps were using most of the memory allocated to their container/VM/etc, 410GB is actually not that many dumps (we're probably talking uncompressed). At 4GB/dump, that's around 100, over possibly several years.

        I just wonder where they were storing them all? At one place I worked, we jiggered up an auto shutdown dump that then automatically copied the compressed dump to an S3 bucket (it was an ephemeral container with no persistent storage). Wonder if they got in through excessive cloud storage policies and this was just the easiest way to exfiltrate data without full access to a DB.

      if a heap dump is a copy of all the bytes in memory, then wouldn't "thousands of heap dumps" likely be larger than 410GB?

      napkin math:

        410GB/1000 dumps = 410MB per dump?
      
        410GB/2000 dumps = 205MB per dump

      • By diggan 2025-05-2010:45

        Might be filtered somewhat, like extracted all ASCII text then compile that into the dump, rather than just the raw dump files.

        Edit: reading the description on the dump again, seems exactly what they did:

        > Some of the archived data includes plaintext messages while other portions only include metadata, including sender and recipient information, timestamps, and group names. To facilitate research, Distributed Denial of Secrets has extracted the text from the original heap dumps.

      The charitable answer is that organizations across US society are currently all trying to be very still and quiet and not do anything to provoke a vindictive assault by this administration.

      The less charitable one is that Moxie was the opinionated and uncompromising core of the Signal Foundation and has been removed from the board and completely vanished from the public eye. What it stands for now is a touch less clear.

      Probably not much they could do, because I'm sure that's why TeleMessage didn't call their app "Signal", but "SGNL".

      Protecting your name is perfectly fine. You're allowed to make a fork of Firefox, you just can't call it Firefox or use any of Mozilla's branding. You're allowed to fork the open source part of VS Code, you just can't call it that or use Microsoft's branding. etc. etc. - you're free to do with open source whatever the license allows, but you're not allowed to use the original name or branding because you have zero rights to those unless the license explicitly stipulates how the name may be used by forks (like how tons of folks use the "Linux" name, and all of them do so with explicit written permission from the Linux foundation, as they own that name as a trademark)

      • By baobun 2025-05-2016:411 reply

        That's not the issue here. VSCode and FireFox are false equivalents. Even if you'd rebrand the fork, Signal forbids non-official clients/builds from connecting to their servers. Enforcement has been selective but the last official word AFAIK is that you are not allowed to fork, rebrand, and distribute a client which alllows you to chat with Signal users.

        Mozilla still allows you to install and download add-ons and use other Mozilla services like VPN and Relay from your LibreWolf build.
