I guess I sort of understand the urge to refuse requests to privately present research findings to companies, but the moral math they're using doesn't really hold up for me. Sure, sharing knowledge and helping people learn is a great reason to give a talk. But if your talk pokes holes people didn't know about in some important technology, then getting those holes closed is another reason, and those private presentations are going to make that happen faster. I think it's totally reasonable to demand compensation for private presentations (else, why not just have the company attend the CCC talk?). I think if you've got Stallman-esque purity, it's reasonable to refuse on principle: you don't want to do anything to help un-free software. But I don't see any such coherent reasoning here.

  Private presentations of things that will be made public are often a win win for researcher and industry. It might even be an education for an industry that has historically not taken security seriously. In this particular case, though, I do detect a principle from the author even though you don't. The gist of the article seems to me to be that the GSMA is seen as a "bad guy" with corporate self interest first over public good and their interest in the talk is to get info (unsaid but presumably to give grounds for an injunction) rather than to get patching...?
  - tptacek 10y ago
    Right, so don't present to the GSMA for free; offer an exorbitant but plausible rate for the presentation.
    - willvarfar 10y ago
      And if they are seen as the "bad guy" then refusing is a principled thing to do...?
      - nickpsecurity 10y ago
        Then that person is naive. The people at these conferences are just employees of companies doing their job. They're there to network & discuss issues. The reception of such a presentation would range from apathy to interest in fixes depending on which participants we're talking about. Theres a small chance of some changes happening. Whereas, that same presentation delivered to people outside the industry has near-zero chance of changes happening. I'm not seeing the conference participants as the "bad guy" if they wanted the hacker to teach them about the problems. I'm not going to say the hacker was the "bad guy" either so much as taking a selfish strategy that only reinforces the problems they research and present on.
        willvarfar 10y ago
        My personal experience of these kinds of industry groups is that the participants who are technical and mean well are misunderstanding their part in the committee and eventually get replaced by political non-techies who better act in their companies interests. Sad but routine.
    - micaksica 10y ago
      The GSMA could attempt to frame this as an extortion attempt against the company, as you have sensitive information you are asking them to pay for that you will be releasing to the public. How do you protect yourself against an angry consortium with deep pockets?
      - delinka 10y ago
        There's a difference between "publication" and "presentation." Have the potential client acknowledge this in writing. You get paid for "presentation" of the material. It'll be "published" for anyone to read after the paid public "presentation" next month.
      - raesene9 10y ago
        If they asked him to present, replying with "Sure I'd be happy to present, my fee is $xxx" doesn't seem likely to be construed as extortion and more than any other speaker charging for their time (be that research time, speaking time or both). If he had approached them cold it may have been a different matter, but that's not what happened here.
      - tptacek 10y ago
        No they wouldn't; in fact, if they attempted to claim that a demand for payment for a private presentation was "extortion", it might actually be their organization that ended up with legal liability, since that sounds an awful lot like per se commercial defamation. You can't "threaten" someone by refusing to give a presentation to them.
- EvanAnderson 10y ago
  "Seems like all they wanted is an exclusive heads-up on work they neither commissioned or supported in any other way." The takeaway, for me, was that the industry group seemed to have a very entitled attitude. I wonder how the author would have reacted if approached for a paid speaking engagement. I don't do security research, but I can understand the motivation of putting my own interests (be they reputation, or getting paid) ahead of public interest. If I don't put myself first how is my work sustainable?
  - nickpsecurity 10y ago
    "The takeaway, for me, was that the industry group seemed to have a very entitled attitude" Maybe. At many such conferences, the attendants or their company actually pay to go there for the benefits of the conference. I'm not sure if the speakers at telecom conferences get paid outside the salary their companies' already pay them. If not, it's unsurprising that the guest speaker wasn't offered money given the conference organizers might see attendance itself as payment given the perceived benefits to networking, reputation, or career progress.
- spydum 10y ago
  agree here. I say kudos to GSMA for even PAYING ATTENTION that the talk was planned, and reaching out ahead of time. It's not like they were asking them not to present. I find there are quite a few folks in security who tend to be glory-seeking drama queens.. More than you might find in mainstream IT/Development. There are still plenty of good ones though, who silently discover and squash with little fanfare. Not sure what that is.. I guess it runs a similar vein to all of those disgruntled angsty network engineers as well. I'm curious if other industries have similar role associations with character traits (e.g.: product safety, FDA, OSHA inspectors all being disgruntled negative nellies)?
- ChuckMcM 10y ago
  Reading between the lines of the original (and I realize I'm being very generous) was perhaps a fear that once they knew the content they would take some action to prevent it from being discussed at CCC. You can't get a judicial figure to agree to an injunction based on "we think this will be damaging to us but we're not sure" but you can get one based on "this is what the guy is going to talk about and we're going to be damaged in this way..."
  - delinka 10y ago
    "...take some action to prevent it from being discussed" This is where the researcher needs legal advice and a contract with the client. Sure, do the private presentation, but make sure you have a contract that says the interaction with corporate staff in no way prevents the researcher from presenting the findings publicly.
    - ChuckMcM 10y ago
      I certainly agree, but it the private presentation offer was predicated on understanding the risk so they could start an injunction process if necessary, then they wouldn't agree to a stipulation that they wouldn't file an injunction. That would defeat the purpose. That said, it might be a nice way to test the waters with them to understand their actual agenda. IF you said, "Sure I'll come and give you a talk but you need to all sign and say you will take no action to prevent my talk from happening in the future in public." And if they refuse to sign such a stipulation then you have your answer on their motives. Note that if that is in fact what they were trying to do, and you "gave away" that you knew what they were trying to do, it might just force them into action anyway even without a lot of evidence that the talk would harm them.
      - Nomentatus 10y ago
        That or they wanted to privately short a lot of stocks... Note that their promise not to push for an injunction holds little meaning, since if a transcript or recording was passed on to some corporation not so pledged, that corporation could still press for the injunction. The way to be discreet is to be discreet.
nickpsecurity 10y ago
Wow. I just read a great example of why good things won't happen in the cellular industry. The people doing research supposedly wanting things to be better were offered a chance to present the problems and/or proposals to the industry. They told them to screw off then wrote a blog post encouraging everyone else to do the same. The industry, esp its leadership, certainly created the problems. Some in industry in middle and on bottom do what they can to fix some of them. Him saying no is an example of the hacker part of the problem where they are about digging up and talking about problems but not taking action that might remedy them. Note: These hackers don't represent hackers in general. Many if not most bug hunters are more than happy to tell the suppliers what they found. I'm only focusing my comment on those with opinion similar to author. The only concern I'd have is they try to prevent the CCC talk with legal action after the presentation scares them shitless. I don't know what the odds of that are for telecoms or CCC talks. I know companies occasionally try to block a damaging talk in the States. I'd ask for a contract from participants saying they wouldn't block the talk or sue me over discussing any flaws I found in my work. If they refuse, I'd offer to deliver them a presentation in video through email or posted to that conference's web site after CCC. Alternatively, show up at next years conference at their expense to deliver an even better talk.

Coming from research land, both academic security and beyond, this seems like a misunderstanding of how the broader CS research community achieves "standing on the shoulders of giants". 1. The impetus in the academic research community is to disseminate, not hide. Likewise, most research is not considered a one-off but a progression. I highly encourage looking at writings by CS research leaders like Simon Peyton Jones and David Patterson on their approach to having shaped large areas of computer science for the last 30+ years. Reasons include improving your own understanding, improving how you present it to others, and getting others engaged. 2. There is a personal bean counting aspect that some researchers are stuck with that limits where they do the first conference publication. They care due to particulars of the promotion process, e.g., tenure, which is in turn subject to publishing rules for academic conference & journal papers around minimal publish units. None of that applies here. HOWEVER, the author is clever here! As the point is to disseminate & improve, by taking an unusual position and writing about that, they've achieved the goal. And final caveat: the non-academic security researchers are among the few that (a) has individuals making up and following personal ethics and ignoring internal review board (IRB) etc. regulations that scientists are required to follow and (b) are fearful/surprised of getting their results buried, most of the time (but not always) IMO as a result of that.
tr1ck5t3r 10y ago
Should have down the presentation either before or after the conference, but should have charged the GSMA for the presentation to recover costs, and profit from the work effort as well, just like any highly paid consultant does. If asked to sign a NDA/secrecy agreement of sorts, thats down to the individual. On the one hand the GSMA might be interested in patching security risks just like bug bounties exist in other IT area's but there again if its only to come up with spin for their defence or a PR effort to appear to be fiddling whilst Rome burns then thats a different matter. At the same time the GSMA dont know if its anything new to them which is a risk for them paying out lots to the individual, but what if their members are not interested in developing new solutions. Big business has a nasty habit of milking the cow until its dry, or flogging a horse until its dead. Its what MBA's like to call part of the maximising return on investment, which is not in the interest of the consumer, and in some cases, these security loop holes are very lucrative when complying with court orders and fleecing the taxpayer indirectly. The Amazon Echo court order will be an interesting one to watch, but the days of big business rolling out any old insecure rubbish seems to be drawing to an end when considering the massive costs to a countries economy when considering the massive cyber attack using IoT devices on the US and to a lessor extent Europe back in Oct. These cyber attacks are only going to get bigger and with Xmas just out of the way, I would not be surprised to see another big one in Jan/Feb/March as more devices get added to the hackers arsenal!

  To be fair, it's far from unknown for the "marshalling a response" to include legal intimidation. Not giving a presentation ahead of time could be viewed as reducing the chance of suppression.
  - droopybuns 10y ago
    I understand your point, but he didn't make that argument. He's been around long enough to know this issue as well. I think it is fair to infer the risk of legal entanglement did not influence his decision by the fact that he didn't bring it up. The way I read his blog post, his main point seems to be about behavior that reflects being a part of a scene or culture that embodies certain passion and values.

Is responsible disclosure not a thing anymore?
delinka 10y ago
"How could they?" Sounds like a Responsible Disclosure kind of thing to me. However, they didn't just ask for the research, they requested additional work in the form of a presentation. That's labor for which there should be compensation. Further, a contract with this potential client that explicitly prevents the client from blocking other presentations and publications; perhaps even barring this client from speaking publicly about the research and what you've found any time before your public presentation. They need to cover the legal expenses for the researcher as well. So you give them a price to get this advance presentation. Maybe you offer an olive branch (and maybe you label it "responsible disclosure") that they might also have access to the research itself before publication. Or maybe you tell them to stick it and go public on your own schedule and throw this industry group under the bus. But that seems like destroying the canyon wall before any bridges could even be built (let alone burning bridges that may have already existed...)
dguido 10y ago
Why are you giving the talk in public if you don't even want to communicate the findings to the people most affected by it?
draw_down 10y ago
I don't understand why the company couldn't just attend the already-scheduled public presentation? Like the author, I would be suspicious of the company's motives for requesting the earlier, private presentation. Not much upside, plenty of downside.

I've done this in other areas (not security) and it's worked out well. Some quick tips: * get everything in writing; * make sure there's not a clause, agreement, etc that prevents you from presenting it elsewhere; * make sure to clearly say what they're allowed/not allowed to do with the presentation - record? share slides internally? publicly share everything? * clearly document that you continue to own everything 100% - (slides, code, etc); * get compensation - I'd suggest travel, two hotel nights, per diem for meals, and at least one daily fee on top (travel+presenting is possibly 1.5-2 days); * make sure you understand what any non-disclosures cover and for how long.

Some quick tips: * get everything in writing; * make sure there's not a clause, agreement, etc that prevents you from presenting it elsewhere; * make sure to clearly say what they're allowed/not allowed to do with the presentation - record? share slides internally? publicly share everything? * clearly document that you continue to own everything 100% - (slides, code, etc); * get compensation - I'd suggest travel, two hotel nights, per diem for meals, and at least one daily fee on top (travel+presenting is possibly 1.5-2 days); * make sure you understand what any non-disclosures cover and for how long.
