Cybersecurity for the Blockchain? HALBORN+SANS Security Summit

[@NessHypegaming]

though im a beginner, this channel has been a god send for my cybersecurity journey.

[@hackvlix]

One of the best cyber security channels on YT, and this is in no small part due to how John conducts himself here as a presenter/teacher. Especially great since he provides a lot of material here that you would have to pay serious money for when learning it elsewhere.

[@myname-mz3lo]

solidity is my second language i learned and it is so fun and different. a great way to learn about blockchain is learning solidity

[@rebeccachoynowski6700]

Jesse Buonanno’s talk was my favorite! It was so insightful to learn how malicious adversaries can leverage the blockchain for new TTPs.

[@burekhacks]

Great content from yesterday's blockchain summit!

[@darkstards5372]

Always believe a teacher when they say "I don't know" and not those who bullshit that they knows everything 👍

[@GoldDeniel]

[@hackvlix]

Why would you _not_ believe a teacher when they say they don't know? 😉 But of course you are right -- don't trust those who claim (or even believe themselves) that they know everything!

[@Alex-nq5nz]

Uhuuu! JH for president !!! Always stunning content !

[@quentincaldway]

Awesome stuff, I'd love to check out this Summit! I must say i've been patiently waiting for something of this sort to pop up in one of your videos. You always do it justice! Blessings!

[@watisonik]

Thanks John! Really appreciate your time on this one.🙏🏽

[@andyli]

web3 security going more mainstream 🙂

[@markyoungkush2925]

Love the videos !! Keep it going 😁

[@davidatclemson]

I'm a 17+ year cyber security professional who is transitioning to the blockchain space. It's an exciting space and there will be huge opportunity if you have background in both blockchain and cyber security. I encourage you to keep digging into it. Solidity is good for understand ETH contracts and Rust for projects like Solana...

[@viq234]

Just started blockchain study myself. I didn't realise Ethereum could run code. Pretty cool

[@CrittingOut]

This is something i was looking for thanks for this content 🙏

[@captainkatz1775]

This seems like a really interesting topic and also really important, as always that's for the videos

[@UGPVlogsLA]

I’m a cryptocurrency trader, who is learning cybersecurity, been studying Solidity, smart contracts, and the blockchain is definitely where I want to be earning money.

[@alexjaimes1141]

Yo I can’t believe that the guy who made Rick n Morty is an elite hacker. Good stuff bro.

[@TheDutchisGaming]

Blockchain security is one of my special interests. Got an 8/10 for a school exam project about the subject digital signatures on blockchain.

[@flojow2403]

you're the man. glad you're making blockchain content

[@hackvlix]

If you find (and exploit) a vulnerability in Ethereum, you just pay your own bounty. 😝 After all, code is law...

[@CodyHoskin]

Yea!!! This is the area I want to get into! I’m pretty sure you gave a talk at my program at Sait 😁

[@persistentbake9041]

Great seeing you in the chat

[@jordangallant7482]

super COOL!!!!

[@rian222]

@John Hammond you mentioned that the videos would be saved. Do you happen to know where? I registered for the Summit, but I wasn't able to watch the videos live.

[@Maryjano]

Also interested in this.

[@elisansabimana6200]

Thank you very much John. This is my first time hearing about the smart contract blockchain security. And am really interested. How can some get started into this as a career ?

[@TheDutchisGaming]

Depends on what you want to do. I guess.

[@arturodelgado7071]

Sadly I couldnt find the recordings on the website. Do you know where I can find them? If im able to have the direct link

[@gaddz4886]

How can i watch these presentations?

[@myname-mz3lo]

in blockchain there are alot of zero days compared to web 2 pentesting. its the wild west , kinda like being a pentester in the early days of the internet.

Hi John. I have been watching your videos for a few days now and I am learning alot. I have now subscribed. Which is the best distro for pen testing and Try hack me . Is kalli better than Blackbox? Thank you for what you are doing 😊

[@TheFirstOnlyRealUltra]

why would anyone share their private key ? did you mean public key ?

[@stamshem12]

I have a question, I would be happy if you could answer me with which programming languages is it possible to know the exact location of the person with a link (without him confirming his location, he enters the link and you know his location)?

[@rasfatzat]

maybe i am wrong but you can have a look at the canary tokens!

cissp needs to have blockchain security as a domain in CBK

[@testingstuff6111]

Wonder why Ziion picked Oracle instead of KVM ... Even Whonix is recommended to be used in KVM instead of VirtualBox due to Oracles bad track record of fixing and giving details about security issues.

[@tonyvelasquez6776]

Can you use KVM with virtualbox?

[@activelearner9924]

is that website free??

[@2ndflare54]

you gotta learn all about how messages are sent on discord and what clicking a discord message would lead a person to do , thats how 75% of attacks go

[@darshans3259]

make a more video on block chain dev

[@pedallknife]

Blockchain will be the next sector for Cyber professionals to innovate and secure the future!

[@realslimchaggy]

can you redo the tutorial of hacking a zip archive without bruteforceing (with a methode I forgot about it)

[@kathleen1685]

Up until recently, I used to process crypto purchases. As with anything, there is a way to hack the process. People are overly confident in the blockchains. Just remember that a chain is only as strong as its weakest link.

Hey

[@eyup8267]

Keep an expert,

[@neondigital547]

Thousands of contracts and new projects are released every single day. What's great is anyone can interact with these contracts on the backend, and anyone can do flash loans. You can borrow say $3 million for a trade that you want to make, and achieve this without any collateral upfront or deposit. Let's say you see a coin selling for a penny more on Coinbase than it is on Binance, but you only have $100 to invest. It's not worth the trouble for a $1 profit you think, right? With a flash loan and millions of dollars at your disposal, you can make that trade and turn it into a very profitable one. Life-changing money in a single trade that ultimately you made for free. Mind-boggling right?.. How do these type of loans work and where can you get them?... Go do your own research like I did lmao!!!

I can't tell you how I started to want to throw up with the whole 'Web 3.0' nonsense. The problem is not 'the blockchain', so much as there is no real reason for it for most things, and the sheer cost in infrastructure for .... anything being done. I'll start with my ... take on it. - The VERY real problem of how hard it is to implement a change, is as double edge sword or worse as it can get. = What happens when someone manages to get a hacked/fraudulent transaction on it? (because only a fool thinks a security measure is impossible to break) ~ What happens when When those who received the fraudulently transferred assets refuse to transfer them back? ~~ Do you build in an override bypass to force it from a master server (which introduces a critical weakness/flaw) and basically invalidate the trust of the very chain by using what amounts client/server model that we have now & have people ask why even use the blockchain if you're going to do shit like this? ~~ Do you build/use/enforce a hack client side to do the transfer? Which is ... as against the point of the blockchain, as it is dystopian & what amounts to enabling forced claiming of property that someone with power thinks you shouldn't have. (Sure we have bits of that now, but atm we can actually fight against it to some degree... imagine it being automated & enforced with no ability to counter it) The problem ... Is an insane level of idiocy of being 'star struck' over web 3.0 nonsense, and about how 'blockchains' are all so amazing, and just how robust they are... but not one shred of thought on the practical potshot of .... does a service like xyz actually need a block chain? what does the blockchain even benefit a service like xyz? While frankly the most important aspect of what people need to ask.. 'How does consumer / Business relations benefit if the blockchain is enforced?' Seriously... Does my One off 'Soda' purchase need to be blockchained forever in a ledger of the local 7-11? Does any purchase that's NEVER intended(like fast food dinner, etc) to ever be resold need to be blockchained? What sort of headache are you going to start giving people reselling old computer gear or blockchained items at a swapmeet? Like .. Really, imagine the migraines obtained all because some dude/dudette wanted to sell his/her computer, and transfer some digital goods that come with said computer. What seriously happens when Art gets blockchained? Who the f controls the blockchains, & which blockchains, & when different blockchains claim that different people own the same thing... who or what decides which one valid & how does anyone go about enforcing compliance to the losing blockchain ledgers?

[@eli_the_crypto_guy]

You could say that about any new technology, could we still survive if the automobile wasn't invented? Yes, would you have the things and be able to do the things now without it? No. As far as new tech and cyber security goes, tech always moves forward faster than cyber security, this is why cyber security will always be behind tech. Not everything needs to be on a blockchain however it is a sure way to decentralize different sectors, take the middle man out is not a bad goal to have. Blockchains provide immutable transactions, without the need of human intervention which can create bias, and error. This is just the tip of the iceberg, block chain has thousands of potential use cases, but to answer your question no we don't need any new technology to survive, if you want to make improve life then that is what tech is for.

[@Konarcoffee]

@@eli_the_crypto_guy Cars solved an existing problem instead of a solution looking for a problem. They also are massive carbon nightmares, so it has that in common with existing uses of blockchain :D

[@eli_the_crypto_guy]

@@Konarcoffee Horses are also a carbon problem, research has shown the carbon foot print for a horse to travel the same distance is on par with a Chevy Corvette. Think about it, water, food, waste, etc. Producing food takes up a lot of resources. going back to horse and buggy is not the answer. ATM's and current banking system uses multitudes more electricity than blockchains, I don't see us going away from that anytime soon.
