      Isn't that just how TI/CounterIntel works? We're not going to share information that could negatively impact ongoing investigations over public channels that can be viewed by anybody. Especially when emotet can change as quickly as they already do

      Does that dude work in CI? I don’t, so I post what I want - not everybody has the same roles. If it forces the Emotet authors to change their code then it’s something interesting (and yes, bad for threat intel companies).

      Forcing the Emotet authors to change their code provides zero value to defense.

      I think anything that challenges attackers adds value.

      Oh, so like the IOCs that we produce? And the victim notification that we do? Thats gotta challenge the attackers without just handing them our research.

      The attackers already know how their code works, because they wrote it, so I don't understand the problem with leveling the playing field by sharing data with defenders. You don't want them to know you know? It seems obvious that people are reversing malware. 🤷🏻‍♂️

      some people (who work for TI companies) have economic incentives to not want these tools shared, because it fucks their competitive edge and means they have to do a rewrite.

      Or, Its because I like enjoying my weekend and not retooling so that we can have 100% visibility at all times. I know "Companies Bad", but lets not forget that we're all people too. Personally, I had tools like this before I got a job.

      I see value in professional analysts tracking bad actors. I also get you feel it's an advantage that don't have to publish what you know, but malware authors do. That said, I think it's a pretty weak advantage, because it's no secret that people track botnets and unpack malware.

      But *how* we are unpacking the malware is important too. And thats something that the actors can definitely change.

      Hmm, not convinced about that, it's not like there's a malware author who thinks you can't unpack their code. If there is, you probably don't have to worry about them doing anything too advanced 🤣

          As I said earlier, it's not that they don't know, it's that they can't respond to every analyst ever, but someone releasing a public tool for all is likely to result in a reaction.
