Alejandro Cáceres, the hacker who took down North Korea’s internet from his home: ‘My attack was a response to their attempt to spy on me’
  • He rented all types of servers around the country in the cloud and designed a denial of service (DoS) attack

    doug-clap What a uniquely skilled individual!

    His feat did not go unnoticed. Over the next year he had meetings with officials from the United States Cyber Command, the branch of the armed forces dedicated to this field. He also met with officers from the Marines, the Space Operations Command and intelligence (NSA). Cáceres shared with them the keys to his successful operation and told them that, in his opinion, similar operations could be carried out with small commandos of two to four hackers. That would give them agility, autonomy and the ability to react.

    Me, a cyber-commando, dressing up in full tactical gear, ready for anything, for the trip from my gaming chair to my refrigerator to get beer while I watch my rented Azure servers send spam to a small country's routers

    He tried, but failed. “To do anything you need authorization, which takes six months to get. And when you get it, what you wanted to do no longer works. That is the reality here in the U.S.: we have very, very good people working on our cyber defense, but they are hogtied. They can’t do anything, even though I know we have the resources to do a lot.”

    Smh our bureaucratic government won't approve my request to start a war with the DPRK from my couch

    If he did this to any other small nation, especially a US-aligned one, he would be charged with a serious crime. The US can't openly do electronic warfare but they can stand by and watch this clown do what basically amounts to cyber-terrorism, a least for a little while

    Anyway, now that he doxxed himself I hope the DPRK actually gives him something to fear lol

    Also

    And ever since he took down the internet in North Korea, he has also been approached by the National Security Agency (NSA). Everyone wanted to know how he did it.

    Lmao

    This is peak journalism, they obviously took him at his word

    You were even able to log into their ancient computers over the network.... every Unix nerd should have the opportunity to log into an ancient Unix system running on a real PDP-11. It's so different... and so slow lol

  • Neoliberals will look at shit like this and still say westphalian sovereignty is real and sacred and borders must be respected.
  • The hacker space is a really great idea, I should look into that, thank you. Would love to find/make some Plan 9 weirdos in my area lol

    Ooh I didn't know what a groove box was til I looked it up just now, looks cool but I'm sorry you found out you didn't like :(

    I hope at least you can find good money in computers or get to work with them in some capacity related to things you like. Like... computers on the ocean... ocean computers... thinkin-lenin or even just getting to help people. I think I would hate most computer jobs lol cuz so much of it is the most useless shit

    I gotta go to bed, am really tired, but it's been fun talking

  • Concerning
  • I would love to see that lmao

  • Neoliberals will look at shit like this and still say westphalian sovereignty is real and sacred and borders must be respected.
  • I actually have worked on a few open-source projects but I never submitted my patches... then I forget about them and they get lost to time lol. On stock OpenBSD (which I run), my desktop PC's audio is kinda broken (long story, can link you a post I made about it if you're curious) so I had to patch the OpenBSD kernel Intel HDA (corpo acronym but the last letter means "audio") driver to make it work properly (had to add a whole new mode of operation for what I think is probably broken hardware, like my motherboard manufacturer fucked it up). I'm still maintaining that patch on my own lol, I need to submit it.

    It's good advice and I don't mind, I'm just maining untreated ADHD rn, maybe that's why I don't do these things

    As for my own projects.... these grand and often probably ridiculous ideas for software (recent example: video game as a filesystem) come into my head and I hack on them obsessively for a while and never finish them because of the scale :(

  • Neoliberals will look at shit like this and still say westphalian sovereignty is real and sacred and borders must be respected.
  • It has been a while since I applied anywhere.... but they all want degrees and professional experience last time I looked :(

    Idk maybe I should start applying again sometime. It's not like I have a resume to show them beyond retail/supply chain work though lol. I don't even have contributions to open-source projects to show tbh. I never finish any of my projects. doomjak

  • Neoliberals will look at shit like this and still say westphalian sovereignty is real and sacred and borders must be respected.
  • I'm sorry ;w; that really sucks

    I can't even find a job in computers cuz I'm not degreed

    I just go from treat servant job to treat servant job

    (CW: misogyny, mention of murder) I ABSOLUTELY LOVE the culture of this hobby

    So you got your technician's license? You get to do such fun activities as: call out on simplex FM voice for no one to respond or talk to the 70-year-old+ "repeater guys" who are on every day from 6 am - 6 pm about uhhhh radios, grilling, ex-wives if you want..... and then listen to the silence when everybody runs out of things to talk about in the presence of an "outsider" (someone who hasn't been on the repeater every day for 10+ years).

    Not interested? That's fine, instead you can just listen to the activity on the repeater when they think no one else is around and hear interesting conversation topics like what the repeater guys would do if someone they were dating had an abortion including, but not limited to, "putting 2 between their eyes".

    Not interested in even that? Okay, if your radio is capable of digital operation, you can connect to a system of linked repeaters and make contact with a different set of 70-year-old+ repeater guys. Once you make contact and talk a bit (maybe even have a good time listening to their stories if you're into that), you can look up their callsign and find their Twitter and find out they're REALLY RACIST and that probably the only reason they spoke to you in a polite manner or at all is cuz you have a "normal-sounding" male voice.

    If this is what the self-policing culture of amateur radio is like (at least where I am in the United States currently) then we need to give many, many more Baofengs to unlicensed zoomers immediately

    Anyway, that has been my experience so far in a rural area in the US. It hasn't been all bad (making contact with the International Space Station was cool) but yeah. I'm going back to a city soon, maybe it will be better there.

    I really do want to get into this hobby and I love the technology (need to find the money sometime to do more packet stuff) but a lot of this type of stuff has been off-putting

    Has anyone made contact with or heard the Chinese space station "Tiangong" via radio recently?

    I had no luck, couldn't hear anything and they (they includes their computers lol) couldn't hear me even though I had perfect line of sight to the station

    I heard they have an APRS digipeater and other amateur radio equipment on board... maybe they turned it off recently or something

    Info is sparse on the English-speaking internet

    Community mesh networking

    cross-posted from: https://hexbear.net/post/2781613

    > Do any of you have experience with community mesh networking? It seems like a fun time and a good way to connect with people (socially and technically lol) in the community. Not to mention the possibility of providing at least limited internet access to people who can't access it by conventional means for whatever reason. A community mesh network might also have organizing possibilities - especially because the state or the cops or a company can't just shut it off or look inside it as easily

    The Automatic Packet Reporting System is really cool and you should use it more

    A lot of hams think the Automatic Packet Reporting System is a system for broadcasting your location, and maybe your status. But the APRS is really a lot of local general-purpose low-speed message-switched* networks joined together by the big Internet (the one we're on rn) into another inter-network.

    *Yeahh, it says packet in the name and is based on AX.25, but really the APRS is only capable of routing complete messages

    It's primitive compared to the Internet but still very useful because of how widespread it is (I'm in some place you could describe as the "middle of nowhere" rn and there are still internet-connected APRS stations and digipeaters in range). The APRS is source-routed, meaning the sender of packets specifies the route they take through the network. You can specify a direct route for your packets to take through the network but most people leave this routing information set to the default on their radio, which is usually something like WIDE1-N,WIDE2-N where N specifies the number of times a packet is rebroadcast by any forwarding-capable station (digipeater) in range (this is how your position and status beacons get distributed to a wide area).

    If you're familiar at all with the history of the APRS then you know its original purpose was to distribute information of local interest and it still does this but is now capable of so much more. You can send and receive text messages (including to the phones of non-hams), e-mails, get weather information, find out when satellites pass over your area, check into APRS nets, subscribe to groups and bulletins, and more.

    Even if you're truly in the middle of nowhere with nothing and no one around, you can still keep in contact with people and beacon your location via one of the satellites carrying internet-connected APRS stations, no commercial satellite subscription and proprietary radio required (don't rely on it though lol). Even the International Space Station has an APRS station aboard

    So you think you're too online? Have you ever done this before?

    Sometimes I like to look up the origin of the taglines. So I looked one up and found this old thread...

    https://hexbear.net/post/1640059

    I don't know this for sure, but I'm almost certain all of the other accts in this thread were eventually banned for being alts of DayOfDoom (HaruhiSuzumiya got herself banned during that thread about DayOfDoom's banning by being sus about it, the other got banned around the same time for unspecified ban evasion)

    Literally arguing with themselves, completely artificial thread, and managed to get into a tagline

    My honest reaction to this information:

    !

    The tagline from this thread is:

    >Apart from further Luna Rossa flankers, would also recommend (re) testing more of the Prada Infusions for a less gourmand, sweet and/or woody, also fresher, crisper and more transparent take on somewhat similar notes, as well as the many AMen flankers, perhaps especially Pure Wood and Pure Tonka, while not entirely dismissing the other flankers and maybe also Kenzo Homme Boisee to certain extents

    The might be a dumb question but... if I enable IP forwarding/routing on my Linux machine without any firewall enabled...

    can someone else use my machine as a router to forward traffic to anywhere else on the internet?

    I'm not entirely sure what the security implications of that would even be if true but probably nothing good

    I don't have any other routes in my routing table other than my "default" route and this machine is reachable via a globally routable IPv4 address. Also I think there are probably other machines on the same subnet (cloud VPS)
