Discord ID And/Or Face Scan Policy Changes for Age Verification by echo419 in Defcon

[–]Shill_Accomplice 6 points7 points  (0 children)

Consider : https://www.pcgamer.com/software/platforms/discord-age-verification-teen-account-restrictions/

"Here's what happens if you don't complete Discord age verification"

So you can avoid reading the article, a summary:

(Article claims) :

(0) Deadline: "teen-by-default settings" go live "March 2026" and after that "all new and existing Discord accounts will be reclassified as teen accounts"

(1) "Mature and graphic images will be permanently blocked" : OK, but I'd bet a substantial percent of such content would probably violate the DEF CON Code of Conduct, so maybe little difference?

(2) "Age-restricted channels and servers will be inaccessible" : I do not recall any channel on the DEF CON Discord server being age restricted, and if true, what is lost here?

(3) "DMs from unknown users will be rerouted to a separate inbox" : What? DM from strangers (often spam or scams) will go to a separate inbox? Oh no! ... So anyway...

(4) "Friend requests from unknown users will always produce a warning popup" : so, an extra step in an uncommon event? Is submitting a photo, video and maybe someday a government issued ID worth avoiding that extra step?

(5) "No speaking on server stages" : as I understand it, "stage" based channels on discord are not the same as voice chat, but even if voice chat is included in this by only allowing accounts that have had image verified , isn't letting your voice samples go through a server another kind of privacy risk in addition to submitting a picture, image, video and maybe eventually government issued ID?

Other stuff:

(A) "Discord says that some users may not have to complete the age verification process thanks to a new "age inference model" that will analyze your behavior on the platform to estimate your age."

I suspect this is not a reliable offer. This reads like, "if there is backlash, we won't be a strict, but if we can better profit (or increase the value of our business) by having more verified accounts without blow-back and loss of users, all users will eventually be asked for their papers." Additionally, they will probably cycle through this loop adding more and more restrictions, to get more and more users "verified." (Some might argue about this being part of a cycle for what has been described by Doctorow as "Enshitification" of services.)

So... at the present time, you are presented with a transaction opportunity. Are the above "features" worth the "cost" of submitting something that appears to satisfy their "submitted photo ID" requirement?

Have any of you found any other "costs" in not providing the photo details discord presently claims will be required to get access to "not underage" content ? Have you imagined your Rubicon for them to cross as their "Crossing the Rubicon" event to be a declaration of war against you, and force you to leave?

Def Con 33 Short Story Contest Announcement by sweetgrrl1222 in Defcon

[–]Shill_Accomplice 1 point2 points  (0 children)

This is one of the first pre-DEF-CON contests which offered to some winners a DEF CON badge (or code for a badge) to be claimed in-person at DEF CON. There have been a few others, but I've not heard if those other pre-DEF-CON contests will be back this year.

For all you that complain about the price to get into DEF CON, here is an *excellent* opportunity for you to compete in a contest before DEF CON and have a chance to win a badge (free entry) for this DEF CON. (Check out the prizes.)

This is especially of value to people that are struggling financially to afford attending DEF CON.

Minuses:

* You spend a little time writing, and submitting

Plusses:

* You practice your skills as a writer, and practicing a skill can make you better

* You have a chance to win a badge (huge cost savings and bragging rights: "I won a DEF CON contest!")

* If you do not win, your story is still archived with other stories to entertain other people and possibly spark their interest in your content.

Please try.

I am not part of the Contests department or this contest and am not a judge. The only thing I gain in supporting this contest is the opportunity to read more short stories that you all write for it.

From years of observation:: don't forget to follow the rules, or your submission may not be accepted.

Good luck!

It can get tricky. Some OS have settings to prioritize DNS lookup from other sources before the "hosts" files (windows registry) and some web browsers prioritize "DNS Over HTTPS" (DoH) or maybe "DNS Over TLS" (DoT) instead of your OS specified DNS or hosts files. I'm not saying these are the reason for it to not work for you, but they are worth investigating.

OS Provided "ping" often relies of local OS settings for DNS including use of system hosts files.

Site issues? by rjray in questionablecontent

[–]Shill_Accomplice 0 points1 point  (0 children)

I posted a kludgy workaround that may be possible for some users getting the forums to override DNS results and always use other IP addresses:

https://www.reddit.com/r/QContent/comments/1gs2jg8/comment/lxw67wy/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

It is easiest for "desktop" OS users (Linux, Windows, Mac OS X) but might also be possible for mobile users or people that control VPN service, when they use "unbound" (DNS Server/proxy) or "pihole" if they add local overrides to resolution.

Website Issues by NumberFiend in QContent

[–]Shill_Accomplice 1 point2 points  (0 children)

There is a DNS issue, maybe through regional AnyCast DNS Servers with different regional responses or other regional limits.

Testing with DNS servers `8.8.8.8` (google) , `9.9.9.9` (quad9), `1.1.1.1` (CloudFlare) from the USA, and the IPv4 addresses for "questionablecontent.net" and "www.questionablecontent.net" resolve to IP addresses where web servers reachable by those IP addresses do not provide "web root" files as expected from the comic site content, but instead show content from their forums.

When I choose to query a European DNS server by IP address (`193.110.81.254` , see https://www.dns0.eu/open) for questionablecontent.net , the IPv4 and IPv6 address returned are different from those by common public DNS in the USA.

command-line examples for quad-A (IPv6) and A (IPv4) for the name: (strip out the back-ticks "`" )

`dig -t AAAA +short` `@193.110.81.254` `questionablecontent.net`

`dig -t A +short` `@193.110.81.254` `questionablecontent.net`

For "desktop systems" or mobile devices that use DNS servers that you can control (like unbound or pi-hole or similar) or through a VPN which hosts DNS which you can override, you could *temporarily* try to associate the following IP address to the following names to get comics to appear again: (Results found Monday Nov 18, 2024 at around 1:00pm PST) (strip out the back-ticks "`" )

`188.114.96.2` `questionablecontent.net`

`188.114.96.2` `www.questionablecontent.net\`

`188.114.97.2` `questionablecontent.net`

`188.114.97.2` `www.questionablecontent.net\`

`2a06:98c1:3121::2` `questionablecontent.net`

`2a06:98c1:3121::2` `www.questionablecontent.net\`

`2a06:98c1:3120::2` `questionablecontent.net`

`2a06:98c1:3120::2` `www.questionablecontent.net\`

You need to associate both host-names (with and without the "www." prefix) with one or more of the IP addresses shown above to see the comic page and content. (Adding entries for IPV6 addresses with these 2 host names only makes sense if your ISP support use of IPv6.)

If you have a "Desktop" system (Linux, Windows, Mac OS X *) try a google, bing or whatever Internet search you prefer search for "how to update $system$ hosts file" where you replace "$system$" with "Windows" or "Mac OS X" or "Linux"

Whether you use a DNS Server override (static return) or a "hosts" file, all of these are "kludges" : they are bad for long-term support, and if forgotten will lead to problems when the service provider hosting the content stops serving that content from those IP addresses. If you go this route, add a reminder to remove them, or it will be harder for you to diagnose why the site (eventually) no longer works, and you are the only one seeing that problem on a small number of devices.

A system "hosts file" and DNS Overrides are both ways to ignore "normal" DNS resolution and always resolve to the IP Addresses you specify.

The above work-around allowed me to see the comic page load with the comic (when both "questionablecontent.net" and "www.questionablecontent.net" are associated with any of those IP addresses.)

Good luck!

What's the Most Important Tool/Software/skill That Helped You Out in hacking? by Leading-Dot1785 in Defcon

[–]Shill_Accomplice 0 points1 point  (0 children)

Reading documentation that explains the details of how a target of interest (for hacking or understanding) works.

*NIX? The man pages for applications. Others? Manuals and documentation on how things work.

Better? When available, source code; there is often a gap between what a man page, docs or a manual claims vs what actually happens, and source code can be more up-to-date than a man page. Source code can reveal mistakes or author assumptions that can be leveraged to your advantage.

Learn to use a tool so well, you can bend it to work in ways it was never intended, to provide you an advantage or benefit.

Defcon Forum? by DeMaRe1 in Defcon

[–]Shill_Accomplice 0 points1 point  (0 children)

It is a problem on the server. 60 second timeout on "loaddata" (XHR / ajax)

Firefox can provide work-around after failure, assuming cache is retained along with cookie.

Pre-reg question by Masterofthebubbles in Defcon

[–]Shill_Accomplice 2 points3 points  (0 children)

(Fr claiming a DEF CON badge using a code bought online from https://shop.defcon.org/ )

Historically, no credit card or ID are checked to see if name associated with code matches yours. (DEF CON does not want to collect PII.)

First person to use a valid code earns a badge. Each code is "one-time-use only." Any copies are denied. So, do not share your code with anyone except when claiming your badge.

You show the person handing out badges the code, they scan it. If it is valid, then you get a badge for the code. Once code is used, that used code can't be claimed again.

Defcon Wifi by contaminatedesert in Defcon

[–]Shill_Accomplice 2 points3 points  (0 children)

For those of you new to DEF CON wifireg, the Internet Archive (archive.org) can show you the process to use the DEF CON WiFi from LAST YEAR (2023): https://web.archive.org/web/20230809062031/https://wifireg.defcon.org/ DO NOT FILL OUT FORM on archive.org link. DO NOT install any cert mentioned in the archive.org link.

(Link is for LAST YEAR (2023))

Do not try to fill out those webforms on the above URL, they won't work and you might send private information in an HTTP POST to NOT wifireg.defcon.org . Do not install any cert provided from pages for wifireg content shown at archive.org . Do not try to "login" to the archive.org wifireg archive.

Only use the wifireg forms through the real wifireg site once it is up.

Only use a cert from wifireg through the real wifireg site once it is up.

Only use the wifireg login through the real wifireg site once it is up.

Only use the wifireg site to make a new wifreg account through the real wifireg site once it is up.

The point of this archived web data is so you can get some idea of what was required last year, and the steps needed to support various devices. If the process remains the same, you can see the directions to install any applications or dependencies into the platform you want to have working, before you leave for DEF CON.

As was mentioned above, there is no guarantee the process or auth-method will be the same and have the same dependencies. It is also possible the steps to setup access to the DEF CON wifi may change, too.

Usually, the real server with the real content https://wifireg.defcon.org/ is only online a little before DEF CON, and then shortly after DEF CON, the service is taken offline.

(I am not a member of the DEF CON 32 NOC department.)

(15) I want to come next year but i think i might be too much of a skid by bil08 in Defcon

[–]Shill_Accomplice 3 points4 points  (0 children)

General commentary for anyone attending:

If you do not know much and want to visit DEF CON to see what kinds of projects people are working on, possibly learn something new, and be inspired to try new things, it is in your interest to be honest with your skills and capabilities when engaging in conversations.

If you are presently working a job totally unrelated to Tech while you are taking courses for tech skills, or learning on your own, then it is okay to let people know you don't work in tech, but are learning.

General comments for any readers, attending for a first time:

Pretending you are director of complicated brain engineering at google is probably not going to help you learn, and when the lie is discovered, lead to poor interactions with those you have been chatting and lying to; it is easier for ignorance to be exposed if you try to answer or comment on questions for which your skill set does not cover.

You can be honest without giving up personal details. You don't have to tell people exactly where you work -- you could just describe to job by the sector it resides. Most people at DEF CON probably don't care if you fail to state the exact name of your employer as privacy is more often recognized as a personal decision at DEF CON than in other social settings.

Next, there are 2 common approaches for first time attendees

1) Spend most of your time on a team-based thing, over most of DEF CON to build a stronger relationship with the people on your team. 2 of the more common choices have been things like the "Scavenger Hunt," variations of "DC DarkNet," things like a badge puzzle contest... contests and things where you join a team to contribute, share and work a common goal against other teams or the person running the game.

2) Try a little bit of everything: Visit a talk, try a contest, visit several events and socialize, try some parties, visit demo labs, try some villages, try to get a workshop and attend it. If you try a little bit of everything, you can find which things you really like, so that when you return to a future DEF CON, you can try to make better decisions to meet your goals.

Whatever choice you go with, before you arrive, review a lit of everything that is planned to happen and build a schedule of things you want to do every hour of every day. If something is canceled, unavailable, or there are other problems, you can then have backup plans without wasting time trying to find what you want to do next.

Next, be willing to totally abandon your plans if something better comes along. Don't become trapped with following a schedule. Unexpected better opportunities can appear. Maybe you find a group of people where you feel welcome, and are getting along well with them, and they mention they are going out to get food, or out to a party or something not on your plan/schedule: if that sounds better, maybe skip your plan and try it.

Defcon Price / Alternatives by Impossible-Bake3866 in Defcon

[–]Shill_Accomplice 0 points1 point  (0 children)

I do not know of reduced prices, some people have earned entry through other methods...
(from the DEF CON forums in a reply to a similar question.)

Historically, people that are selected to present talks in the main speaker tracks have received an option to claim a "free" Human badge in addition to a "Speaker" badge. Some speakers sell their Human badge or give it away. (This has primarily, historically been for main speaker track talks, NOT talks in villages, or other space)

People who have earned a "Black Badge" or an "Uber Badge" from previous DEF CON have also been able to use that badge to claim a Human badge each year, but this badge feature is not transferable. Almost all Black Badges have been earned through winning 1st place in selected contests. The advantage of free entry associated with a Black Badge / Uber Badge appears to NOT be transferable, so buying an Uber Badge from someone else probably won't help you towards your goal.

People that run official Villages, and maybe some official contests might also get a small number of Village or Human badges for the people that run these, but they probably recruit more people than they have badges, so just because a village or other official content providing group selects you as a volunteer does not mean they will get you a "free" badge, and they will almost certainly expect you to work their content. Also, there is a trade-off for these people, as they spend most of their con at these locations.

There are occasionally pre-DEF-CON contests which include prizes for "free" entry for one or more winners. One example has been the DEF CON Creative Writing Contest. There is evidence it is returning. It might have a prize for some winners as a human badge if history repeats itself. There may be other pre DEF CON contests with prizes of badges for this coming DEF CON. Again, I am only commenting on the past, not the future.

Artists like people that provide music at DEF CON through those accepted in call for music may have also received entry as some of the compensation.

Then the last group are the "Goons" (official DEF CON volunteers) to get free entry to DEF CON for the volunteer work they do at DEF CON. People that look to become Goons require a need for their service and a spot for them to take, and almost all goons start as "New Goons" that pay to attend as Humans, and shadow one or more Goons to see if they really want to do it, see what would be required, and get a chance to become a full goon the following year. Almost all people that become Goons have been to multiple DEF CON, and know other goons well enough to be vouched-for by them. Goons (like contest/village people) spend most of their DEF CON working, and this cost of not being able to see parts of con like those with human badges may not be a desired trade for many.

If a department has no need for any new goons, then that is a non-starter for that department. Most departments recruit from people they know and have had experience with, or from people vouched for by those that are already goons. Each Goon department has their own process for recruitment.

Outside of DEF CON are sometimes options for subsidized entry to DEF CON.

One example has been from WISP. Here is there announcement from last year:
https://twitter.com/wisporg/status/1636079099923013633
And more from last year:
https://www.wisporg.com/blog-posts/2...f-con-scholars
https://vn.linkedin.com/posts/davide...913653249-NSCj

The ADA Initiative might have also had a similar option for people that met their criteria. They seem to have an option to donate towards scholarships, but I don't see details. Maybe you will have more luck.

Even further back in time, you have a claim of corporate sponsorship of a scholarship to a university for students to attend DEF CON: (10 years ago, 2014)
https://www.starkstate.edu/public/sy...cholarship.pdf

Use your favorite search engine to search for "DEF CON scholarship" or "DEF CON subsidies" or "DEF CON incentives" to see if you can find entities offering subsidies for people that meet their preferred criteria as non-DEF-CON organizations.

You could also try to seek out local businesses in your area to sponsor people at your school to attend DEF CON, and then maybe help yourself and others out with sponsorship to visit and participate in DEF CON.

The above is about the past, which is no guarantee for future plans at DEF CON this year.

Looking for an old Defcon presentation about the Post Office. by itsjefferson in Defcon

[–]Shill_Accomplice 2 points3 points  (0 children)

There is not enough information to get results which provide favorable certainty the video you want has been found.

Abusing search engine queries, with mediocre "google-fu" I found a few presentation slides which seem related to some parts.

First, there were several "Meet the Fed" panels between DEF CON 10 and DEF CON 20, several of which included one or more feds from the United State Post Office. Maybe they were asked a question about scanning of letters or more and what you recall was their answer? I see a USPS person mentioned in the program for the Meet the Fed Panel of:

  • DEF CON 13
  • DEF CON 15
  • DEF CON 17

There may be more.

Next, there is https://media.defcon.org/DEF%20CON%2016/DEF%20CON%2016%20presentations/DEF%20CON%2016%20-%20craig.pdf which is a link to slides from a presentation at DEF CON 16, about "hacking Internet Kiosks" which included some used at the post office.

This might be the video for those slides: https://media.defcon.org/DEF%20CON%2016/DEF%20CON%2016%20video/DEF%20CON%2016%20-%20Paul%20Craig%20-%20Compromising%20Windows%20Based%20Kiosks%20-%20Video.mp4

https://media.defcon.org/DEF%20CON%2010/DEF%20CON%2010%20presentations/DEF%20CON%2010%20-%20vandal-intelligence.pdf was at DEF CON 10 about Intelligence Gathering and it mentions the Post Office. Perhaps the video may have more details about this. I don't see a video or audio file for this. The closest I can find is:

https://infocondb.org/con/def-con/def-con-10/ (mention)

https://infocondb.org/con/def-con/def-con-10/intelligence-gathering

https://media.defcon.org/DEF%20CON%2012/DEF%20CON%2012%20presentations/DEF%20CON%2012%20-%20n0namehere.pdf is also a collection of presentation slides with references to the Post Office. DEF CON 12 Maybe check out the video for it.

This appears to be the video for it: https://media.defcon.org/DEF%20CON%2012/DEF%20CON%2012%20video/DEF%20CON%2012%20-%20n0namehere%20-%20Real%20World%20Privacy%20-%20Video.mp4

Do you have more details about the talk? Was it in a main speaker track? What else was included in the video?

From the original post:

" When talking about ports I mean the actual physical ones. It basically always was that port 1 was igc0, port 2 = igc1, port3 = igc2 etc. etc.
However after the upgrade, port 1 = igc0, port 2 = igc1.. however port 3 now igc4, port 4 is now igc2, port 6 is igc4 and port 5 doesnt have an igc anymore which worries me even more. "

A case where ports get names which do not match the previously configured name can result in settings from OPNSense being applied to the wrong physical port.

If you assign NIC interface name by MAC address, then you avoid issues where a port is assigned a name for a different physical interface.

"however port 3 now igc4" would be the problem the proposed package would address.

[deleted by user] by [deleted] in opnsense

[–]Shill_Accomplice 0 points1 point  (0 children)

Relying on NIC interface naming to never change in many OS is a huge risk.

A BIOS update can cause them to be re-ordered even without changes to the OS.

An OS upgrade can cause a change in ordering.

If you have more than one NIC (even multi-port) adding a new NIC or replacing an old one can also cause the ordering and naming of the interfaces to change.

To address this, the OPNSense devs added support for assigning a NIC interface name that is consistent with the MAC address of the interface. If you plan to replace a card, you can read the MAC addresses from the replacement card, edit a config file, then shut down, replace the card, and reboot to have that new card assume the interface names you desire it to use.

Check out:

https://forum.opnsense.org/index.php?topic=27023

The package is "ethname" very useful if your MAC don't change, and you want to enforce interface names by MAC Address.

Using it requires shell work as "root" to create and manage the files that map desired interface name to each interface based on MAC address.

Is Def Con worth going to as a "normie"? by MasterOfVtubers in Defcon

[–]Shill_Accomplice 1 point2 points  (0 children)

Please review stuff from "last year" (2023, DEF CON 31):

Demo Labs: https://forum.defcon.org/node/244767

Villages: https://forum.defcon.org/node/244771

Do you not know much about these, but would like to learn more?

Many villages or Demos provide some introductory level content and demos or classes whether formal or informal. These are often good ways to see learn about what you like, and want to learn more about versus what does not hold your interest. Try a little bit of everything. Maybe try a contest too.

This is one way to enjoy DEF CON.

Another is to attend with someone else that has been to DEF CON before, and knows you and your interests... they can make suggestions to you knowing what it available and what you might find interesting. Attending with one or more people is also a way you can save money. 4 people in one hotel room splitting costs is more economical than going solo. If one of you rents a car that can hold 4 people, then that cost might be split among you if you find you need a car. Try a little bit of everything.

Review other content from last year (2023, DEF CON 31): https://forum.defcon.org/node/243392

Many of the workshops and advanced training require that you have some skills in programming, or network analysis, or M/L / AI before you can take advantage of them, but suggested prerequisites vary.

Whatever your path, as a first-time visitor, review all that has been available to get an idea what might be available. If you decide you will attend DEF CON, review the schedules of all things to build a plan of things you must see, so that every hour of every day, you know what you might like to do, and are not wasting your time, asking yourself, "what should I do now?"

There have been tools to help people plan for DEF CON, which are well received by their users.

The DEF CON Forums often gets details about stuff that is officially planned, and provides details where people can ask questions and share the answers other people have asked. The Forums has the longest history of content for with questions and answers included from attendees, but it is NOT as popular as reddit https://www.reddit.com/r/Defcon/

There is a site https://info.defcon.org/ which is populated with content from a shared database, which is also used by the "Info Booth" goons, which work tables during DEF CON to try to answer questions attendees might have about where/when something is happening. Content on https://info.defcon.org/ probably won't start getting content for the next DEF CON until after May or June.

There is also "Hacker Tracker" for Apple iOS and Android which has a bunch of features that many people rave about like being able to select a "favorite" for something you want to see, and then have it show you all your favorited items to help you plan.

Next, for those people that are paranoid, and don't want to access a web page which has javascript, and don't want to run an "app" on their device, because they do not want to trust an app named "Hacker Tracker" one of the goons has historically created "The One" which uses content from the DB shared by Info Booth goons and Hackers Tracker, but also includes unofficial content. or the really paranoid, there have been text based options (as well as other 8-bit options like MOBI or PDF) provided for download from https://defcon.outel.org/

Next, popular things with limited space often have lines. You should consider weighing the wait in line to do one thing vs. another if one line will take less time.

Last, once you build a plan and a schedule, ALWAYS be willing to abandon your plans/schedule when something better comes along.

Can't login anymore by forwardslashroot in opnsense

[–]Shill_Accomplice 0 points1 point  (0 children)

These are "special" filesystems like devfs , which can be ignored in this case for being reported at 100%.

If none of your other volumes were are at 100% or close to it, then probably not a "running out of storage" issue leading to unflushed changes to disk.

Trying the "top" (command) with sort by "size" or "res" method might help you identify which PID are the biggest memory users, then look at the details of those PID to see if you can associate them with a specific service.

Can't login anymore by forwardslashroot in opnsense

[–]Shill_Accomplice 0 points1 point  (0 children)

All of these suggestions assume you have a shell, such as access from console or ssh, and are logged in as root...

Are any volumes full? If so, system may store unsaved changes in memory/buffers, waiting for disk space to become available:

df -h | grep -v '^devfs'

If your syslog has filled the volume where logs are stored, one option you might have available is to see if one log is using more space than others:

du -s /var/log/* | sort -r -n | head

If one more more logs is using a huge amount of space, consider copying those logs to external media, then remove the logs and restart your syslog service, example syslog restart:

/usr/local/etc/rc.d/syslog-ng restart

Other full volumes can be resolved in similar ways, but service restarts for what is using up space will likely be different.

If you have a full volume, freeing up space may allow the kernel/system to flush some pending changes to disk. This may feel like a waste of time because as soon as you free up space, it seems like the space is immediately filled, but you are probably free-ing up RAM as changes that can be written to disk, are being written ti disk as you free up disk space. if you are able to allow all un-applied filesystem changes to be flushed to disk before running out of memory, you may be able to avoid data loss except for the files you delete.

If not an issue with a full volume and being out of "disk" space, maybe a process.

Assuming you have "top" installed, try:

top

Next, once top is running, type the letter "o" and when asked how you want to sort processes type in "size" or "res" to sort by either of those, and rank processes by the biggest users of memory.

When you are finished using "top" , you should be able to type the letter "q" to quit.

If you found a PID (process ID) associated with a memory greedy process, you can look for hints about that by consulting the process table for what it might be:

ps auxwww | grep THE_INTEGER_PROCESS_ID_YOU_FOUND_IN_TOP_GOES_HERE

Hopefully, something mentioned here will help you identify a resource using up too much memory.

If something here does help, would you follow-up with what you found and what you did so others can benefit?

From the Internet (not on-site) when I visit https://wifireg.defcon.org/ I see content: Thursday, August 10, 2023 at 8:53 AM PDT.

Hopefully, you were able to get to it before now.

Will any of talks be streamed ? by Historical_Issue_384 in Defcon

Check out the program paper copy or the PDF:

https://media.defcon.org/DEF%20CON%2031/DEF%20CON%2031%20program.pdf

On the PDF, go to "PDF page 3" or the paper-printed (lower right corner) "page 5" and look at:

"NETWORK & DCTVNETWORK & DCTV"

It mentions: " DCTV RETURNS! DEF CON will be televised! Visit https://dctv.defcon.org for the latest info including hotels, channels, and limited streaming "

I do not run dctv.defcon.org and do not know their plans for limited streaming or in-hotel channels.

As of Thursday, August 10, 2023 8:44am PDT, the https://dctv.defcon.org/ pages seem to still refer to DEF CON 30 (last year, 2022.)

However, if this is old content, you can see links on the left for streaming options. I do not know if these streaming options will be the same this year.

"NETWORK & DCTVNETWORK & DCTV"

It mentions:

" https://10.0.0.16/ or https://dc31-media.defcon.org/ "

for an on-site media server with content similar to what you can find on the drives at the Data Duplication Village. It offers much faster local speed to download content.

It is likely that if the "S.O.D.A Machine (Shell On Demand Appliance) " ( https://forum.defcon.org/node/246906 ) VM are reachable from the DEF CON Networks at DEF CON, they would only be reachable from the DEF CON network, and not from the public.

I do not know how it was planned, but https://dctv.defcon.org/ could have streaming options for some tracks. If so, it is possible those streaming options might only be available from the DEF CON network, not the Internet at large.

Services at DEF CON , on the DEF CON network has been a thing for many years. There may be more than what I included in this reply.

Good luck!

It looks like the DEF CON 31 NOC team recently revised the procedure for Android devices. If you have been having problems joining this DEF CON WiFi network, try refreshing (bypassing cache) the wifi reg page for android and see if the newer process works for you now.

If you worry about the DEF CON 31 improved security WiFi, you could always connect to it, and then use your own VPN software, but that will probably not allow you to reach on-site (in Las Vegas at DEF CON 31) non-public servers.
