[@neo_the_chosen_one777]

thanks for the premium trial....

[@jaden8573]

you leaked the ip in the obfuscated code he generates, just deobfuscate and its in plain text. maybe blur 25:38

[@unlucky1307]

I have some concerns about the coverage here, it seems looking at the github for the project InfosecREDD was deliberately removed from all credits by Jakoby despite working on this project.

[@digitalcivilulydighed]

This was brilliant!

[@FutureWarCultist]

The fact bro here is still doing the right thing after taking the shaft on huge bags speaks volumes to his character. The bazaar will gladly offer fair value for your work ❤

[@davidbombal]

Exactly. We need Ethical Hackers in this world to help better protect us. And companies need to look after the good people like Jakoby.

[@neiltropolis]

He was a marine sniper, served his country and disrespected big time. The man is a prince.

[@swoodc]

what huge bag

[@gyp.]

​@@swoodcwhat he spoke of towards the start of this video was a pretty huge exploit, that he made Microsoft aware of, they *tried* to patch it. He worked around it in 10 mins, he finally spoke to someone directly and disclosed it again, with some of his own suggestions. He never even heard a word back from Microsoft but when they "patched" it again he said at best Microsoft looked directly at some of his code in his GitHub, and used it on their patch. Again he heard nothing back from Microsoft and they kinda bit some of his own code in the patch. Anyway an exploit of this level at Microsoft, especially with how many machines this can affect and the permission they would get. This is a $100k bounty that Microsoft didn't pay him out. He is still trying to get the actual credit for the disclosure so he can earn his bounty. He could have sold this on the black market, he could have just dumped it on the Internet but he understood how much damage that could do. He is trying to do the right thing by helping Microsoft by doing responsible disclosures, and because this work takes time and because companies know that other people would pay money for these exploits. Many companies offer "bug bounties" for responsible disclosures of bugs that their software/web sites have. That is the money others are talking about.

[@mattrogers6646]

​@@swoodcDidn't get his rightfully earned bug bounties.

[@deathspirate2170]

Great video thanks David! Jakoby did an excellent job of explaining Data Bouncing. We have submitted a CFP to Defcon for the rest of the research we have been doing in this space so fingers crossed that gets accepted. It's awesome to see Data Bouncing being absorbed and built on by the community.

[@DarthDweeb]

Jakoby, you are born to tell stories. Thank you for sharing yours.

[@IamJakoby]

This comment warmed my heart to read, I appreciate you 😊

[@traviskline2836]

I understood about 1% of this but I cannot quit watching your videos.

[@Sammenluola]

This tbh! I have no idea what's being discussed, and I'm captivated like a fly under an anvil.

[@ShaySoFresh777]

Jakoby is legit a one-man army!! If Michelangelo were alive today, he'd be Jakoby. This is a guy I wanna learn from!

[@IamJakoby]

❤❤❤

[@HAMETE]

The dns exfiltration is crazy! Thanks for sharing and shame to Microsoft

[@user-hg7xs5hv6j]

im amazed that jakoby has the right set of morals and doesnt allow the fact that he was screwed by the bounty, and is still fighting the good fight. godspeed jakoby.

[@IamJakoby]

The only thing it takes for evil to succeed is for good men to do nothing. This world is full of people I care about and want them to have the best lives possible

[@vrts]

@@IamJakoby just wanted to let you know that your attitude and perseverance is inspiring. Keep it up.

[@freem4nn129]

Thx for sharing Jakoby, you got your heart and passion in the right place !

[@c0ri]

Great show.. love these really simple callouts. It was eye opening seeing those modules which could be made by anyone. MS is going to have a headache grabbing control back of all those modules.. but now that they are out, they will need to change Powershell and UAC as well to fix this. Man.. Anyway, great guest and show today!

[@davidbombal]

Glad you enjoyed the video! Jakoby is doing amazing work!

[@inbrandtive]

This guy deserves more appreciation.

[@scottv2468]

Amazing video David as always! I'm curious to know about how it would hold up against ThreatLocker and the heuristic-based detection.

[@christianlohmann8577]

Thanks for the heads up. Scary 😮 and bad from MS to not compensate for the support they receive from people like IamJakoby. And thanks David to give them the time sharing the risks.

[@chathurangaonnet]

Great video. Thanks David and Jakoby !!!

[@TalkingSasquach]

Heyyy nice to see you guys together!! I'm psyched to watch!

[@brycenamorozo8630]

That’s crazy I’m a junior majoring in cybersecurity and I live in Waipahu! Crazy small world thank you for sharing your stories your demonstrations on reverse shell was mind blowing and I’m excited to get into the cybersecurity field

[@IamJakoby]

I miss Hawaii sooooo very much 😢

[@guillaumelavoie1544]

Thank you for the interview. I am speechless.

[@ProgrammingWithDaniel]

How about making a map of the all sites like adobe that support that, and send the chunks of a file to the all sites, an then just listen the response from all of them and combine the chunks in the order of the mapped sites? Man, this is insane, this video is in the list of the best ever in my opinion. Congrats Jakoby brilliant mind, thanks David!

[@IamJakoby]

Yuuuup so that ls what the team I was working with did actually. Its pretty much all sites that use akamai And then yup you can just blast it across as many domains as you would like and rebuild from there

[@Metalswede]

Such an interesting video for a student who’s studying IT security, even though I probably only understood about 50% of the things mentioned in this video haha. Thank you for sharing this and letting us find out about Jakoby!

[@C8zzzD]

Ooh wee, I'm learning so much... ❤ instantly hooked

[@kfluhx]

I'm sure, especially in this community, it's incredibly hard to share the personal experiences that inspired people down this path. Very much appreciated and inspiring in return. Thanks for bringing both the technical (which I barely understand enough to follow along), and some much needed humanity. Theoretically, it's the only thing that separates us from AI at this point, right? 😅

[@cef-ym3gb]

Thank you for your service. ❤

:O WOW. So many amazing factors! Bounty very deserved.. Kinda scary providing the public even this much information in a video like this lol

[@dustinhxc]

Heyyy happy to see him here!! 🎉

[@Striker9]

I first saw iamjakoby here a few weeks ago when i built a pico rubber ducky. Amazing to see the guy himself, never thought to look up his name on anything except the ducky script repository.

[@IamJakoby]

Congrats on your build and I'm happy I could help in some way 😊

what an inspiration

[@StaticSkyTV]

Its like looking at the stern of a boat. Green is starboard, red is port.

[@scottspa74]

This was absolutely AMAZING! Jakobi 1000% needs a bounty award for this, and Microsoft should be kissing his ass and hiring him for whatever salary he desires lol. Also, everyone should be made aware how sh1tty MS is being by making everyone so vulnerable.

[@definitelyno]

If he reported a vulnerability that meets the criteria set up by Microsoft's bug bounty program yes he should get a reward, otherwise not. From what I understand Microsoft did not think whatever he reported was worthy a bounty and from the video I don't see why they would be wrong.

[@scottspa74]

I guess, if you support the letter of the law, rather than the spirit of the law (obviously we're not talking about "laws",but in principle). If someone made MS aware how vulnerable their SW is, they should be kneeling down to him. I did an internship with someone who was pretty instrumental with creating UAC for MS, and he always stated how bad MS code is in terms of just accepting bad code and moving on without addressing the underlying bad code, due to how many things would break as a result of trying to fix it. ​@@definitelyno

[@scottspa74]

​@@definitelynoalso, MS is the primary SW of nearly all users of computers; they should be VERY concerned and want to address the issue, and reward the whistleblower.

[@definitelyno]

@@scottspa74Still, what is the issue.

[@sharky9493]

OMG, what a fantastic guy!

[@adamchalabi3654]

[@davidbombal]

Thank you!

[@ryanziller220]

1:11:35 I have to be that guy about the semantic expressions being used wherefore the focus of developers in the cybersecurity space is 'how COULD this be broken' to sanitize or use some other weak security measure to set up the best digital reaction to a cyber threat. Ethical hacking or generally all hacking is about the 'how WILL I destroy this system'.

[@livestreamvi7991]

Thank you sir i am working in dns reverse shell by using powershell so this video is so important to me thank you.your are great teacher thank you.god bles you❤❤❤❤❤❤❤i am suppoting you

[@marcohiltebrand6471]

What a great video about such an interesting topic 😊 i can literally imagine how it was to think hours in sleepless nights about such a challenge. After the cryptophones topic became public, I was fascinated of the idea to construct a secure data exchange method which is using a bunch of alternating channels like social media platforms and others. Even if I am not a hacker, the idea of chunking up the data and either include meta data or being able to link it felt like a lottery win 😊

[@countvonthizzle9623]

@David Bombal & @Jakoby - Is it worth the time to block "Powershell Gallery" in the Windows "hosts" file? Or will this do nothing?

[@50PullUps]

The PSGallery is no more a vector for malware than the entire Internet is a vector for malware. On your personal systems, use the PSGallery as much as you want. In a corporate environment, Allow for specific whitelisted PCs and then Deny All for all other PCs.

Yea that guy pretty much nailed it. There will always be vectors to look out for its just learning about mitigating the risk.

Yes that is correct, it's just you have to do some extra recon on your target to see what else could interest with these packets
