According to BleepingComputer.Com, “On Wednesday, ARRL revealed that it had indeed paid the attackers a [$1 million] ransom not to prevent stolen data from being leaked online but to obtain a decryption tool to restore systems impacted during the attack on the morning of May 15.”

A member bulletin detailing the situation was sent to members on Wednesday, August 21. The text of this bulletin can be read online.

Las Vegas hacker convention attendees complain of harassment by Resorts World staff

The hotel of Resorts World Las Vegas played host to many attendees of the convention this year, which ran from Thursday to Sunday at the Las Vegas Convention Center, and attendees of the cybersecurity conference complained that they were being treated like criminals by security.

In notices from Resorts World shared on social media, the casino-hotel warned guests of “room checks on all stay over rooms” in the block reserved for DEF CON attendees. Guests have also shared their own personal stories to social media, complaining of harassment by overzealous security staff with the intention to intimidate.

…

Some DEF CON attendees shared their negative experiences on forums, such as Hacker News. One, known by the username FickleRaptor, said security demanded their ID and threatened to have them arrested for trespassing. “The issue was that my colleague was one of the amateur radio VEs for the Ham Radio Village and happened to have his handheld with him,” they explained, adding that the guard was “aggressive, entitled, and arrogant.”

OM80SNP celebrates 80th anniversary of Slovak National Uprising

While listening to the August 21, 2024 podcast of Radio Slovakia International’s daily English show, I was surprised to hear a report on OM80SNP, a special event station commemorating the 80th anniversary of the Slovak National Uprising (Slovenské Národné Povstanie).

This station has been operating since August 1 and will continue through August 31, 2024.  A special QSL card is available.

Being Slovak-American, I wish I’d known about this sooner. I still have a chance to work them and get a QSL card, though.

I attended DEF CON 32 a week or so ago, and like many “hacker” conferences, attendees got an electronic badge. This year’s badge was built around the new Raspberry PI microcontroller, the RP2350. It actually works like a GameBoy, and you can add games like you would a GameBoy. Here are a couple of videos that talk about the DEF CON 32 electronic badge:

• https://www.youtube.com/watch?v=tPrIO0fhikE

Some of the “villages” or special interest groups, such as the Aerospace Village created their own badges.

At DEF CON, I attended a talk by a fellow who’s created an open-source design—both hardware and software—upon which you can build a badge for your event. He calls his badge OpenTaxus, and you can find the documentation here.

Since these things are so popular at hacker conferences, I wonder why they aren’t more popular at amateur radio events? Is it because hams are just too cheap to buy something like this? Or, maybe, it’s because hams are just not as “creative” as hackers.

At any rate, I’m thinking about coming up with some kind of electronic badge for the 2025 Dayton Hamvention. If any of you have ideas for the badge—or would perhaps be interested in working on the badge hardware or software—let me know. If we are going to do a badge, it would probably be a good idea to get started on it now.

I’m not a real fan of Las Vegas, but DEF CON is held in Las Vegas, so if I wanted to teach a one-day Tech class there, I just had to go. It was a fun, but tiring trip.

Getting there

I kinda made my travel arrangements last minute because the Ham Radio Village (HRV) folks weren’t sure that they were going to be able to secure a room for the class. That being the case, the only flight I was able to get was a late afternoon (4:50 pm) flight from Detroit. Same with the return. Instead of an early morning flight, I had to opt for the 1:15 pm flight, meaning that I wouldn’t get back to Detroit until after 8:00 pm. I managed to keep myself busy—there’s always something to do—but Wednesday and Sunday were mostly wasted.

I flew on Spirit. Enough said, I guess. It was packed. It was cheap, though, and the flight was direct to and from Detroit.

The flight out was fine. We even arrived about a half hour early. The return flight, however, was a real mess. We pushed back from the gate about 15 minutes late, but then, we sat on the tarmac for another hour and 45 minutes. I never did get a good explanation for what was happening. We arrived in Detroit an hour and a half late.

What a circus!

I stayed at Circus Circus because that’s what came up on booking.com as being close to the convention center. It was definitely close, but I really should have looked around some more. Circus Circus was built in the early 1960s, and it’s really showing its age. My room was clean enough, but the furniture was kind of banged up, there were spots where the wallpaper was peeling from the walls, and the air conditioner was very loud. Ugh.

There are many hotels around the convention center, and I think that if I shopped around more, I could have found a place with better rooms and a lower price. I took notes, and when I go back next year, I’ll be looking into those places as well.

Que rico!

Like everything in Las Vegas, the food is expensive. I lucked out, though, and found a place that was affordable, close to the Las Vegas Convention Center and my hotel, and delicious: Tacos El Gordo on Las Vegas Blvd.

The tacos at Tacos El Gorda are the real deal. They advertise that the tacos are made Tijuna style, and you’d be hard pressed to find better tacos there. They’re made with handmade corn tortillas and homemade guacamole and salsas that are made from scratch daily.

When you enter Tacos El Gorda, you get into one of six lines, depending on the type of taco you want. On my first visit, I opted for the pork (adobada) tacos. In some places, they call this type of of taco a taco al pastor. The meat is sliced from a rotating spit, much like gyros is made, directly onto a tortilla. It really was excellent and only cost $4.12 per taco.

My second visit I decided to get a little more adventurous. I got into the line featuring organ meats, and after waiting in line for about a half hour, I ordered one taco de suadero (beef brisket—not so adventurous), one taco de cabeza (beef head—a little more adventurous), and one taco de buche (pork stomach—really adventurous). I liked the suadero and cabeza, but the buche not so much.

I’’m not really a gambler, but…

I’m not really a gambler, and in 2022 and 2023, I didn’t gamble a single cent. Many years ago, though, I bought some blackjack books and learned some basic strategy. So, this year, when I found a couple of blackjack machines in the Circus Circus casino that would accept $1 bets, I decided to give it a go.

Friday night, I fed a $20 bill into the machine and started playing. This machine was a little complicated in that it had a lot of side bets that you could make, such as whether you were dealt a pair or dealt 19+. I lost three of these sucker bets at a buck a pop before I figured that out.

Once I got that straight, I started playing plain old blackjack using the basic strategy. Using this strategy, your odds about 50-50, and that’s about how it played out. I pretty much broke even over the next half hour. Right at the end, I had a bit of a lucky streak, and when my total hit $20.80, I cashed out.

I say “cashed out,” but what the machine does is print out a ticket that you then have to take to a cashier to actually get cash. I thought that I might play a little again, so I just pocketed the ticket.

Saturday night, I did indeed decide to give it another go. There were only two machines that were working when I got to the casino, so I wandered around for a bit, visiting the circus stage and watching the hotel visitors try their luck at games on the midway. When I got back to the machines, one guy was just getting up, so I took his seat.

At first, I had a run of bad luck, and my total dropped to $15.30. But then, I got on a little bit of a roll, and built my total up to around $20 again. At that point, I played even with the machine for about 10-15 minutes. After a lucky streak bumped my total up to $25.50, I hit the cash out button again, and took the ticket to the cashier to collect my winnings.

My biggest class yet

The class went pretty well. Because we were only allowed to have 100 people in the room, HRV limited the pre-registration to 75. Despite the late start in publicizing the class, it filled up quickly. After getting all the pre-registered people in, they started accepting walk-ins, and we ended up with a class size of 90, making it the biggest class I’ve ever taught!

Since it was a bigger room than the one I taught in at HOPE, the setting wasn’t quite as intimate. The students had questions, but not as many as the HOPE class. Perhaps the size of the room had something to do with that. I’m not sure.

Unfortunately, we only had the room for seven hours, meaning that the students couldn’t test right away. Instead, they would have to take the test at DEF CON itself.

As a results, I’m not sure how many of the 90 students eventually passed the test. I know that over the course of the next couple of days I ran into several students who had passed the test. My guess is that a very high percentage did pass.

Mind-boggled

DEF CON is a truly amazing event. It’s a “hacking” conference, but the definition of hacking is about as broad as it can be. There were special interest groups, or “villages,” for a wide range of activities including hardware hacking, voting, lock picking (physical security), embedded systems, Internet of Things, and many more. And not only were there a couple of speaker tracks designed to appeal broadly, each village had their own series of talks. The enormity of it all just boggles my mind.

On Friday, I checked in at the Ham Radio Village and dropped off some of my No Nonsense business cards. I offered to help out, but they seemed to be all set, so I wandered off to experience the conference. I had a fun day attending talks, including a talk on open-source hardware for conference badges. I’ll be writing more about this later.

On Saturday, I updated my Ham Radio for Hackers slides and spoke on the topic in the Ham Radio Village. Like at HOPE, I had a really good turnout, and it was standing room only.

Immediately after, I went to hear a talk by Cory Doctorow in the main room, where he talked about the “enshittification” of the internet. If you haven’t’ heard this talk or read his articles about the subject, you should.

After that, I dropped in to the Women in Security and Privacy Village to make a “friendship bracelet” for my wife. I had been wracking my brain for something to bring home for her, and I knew the moment that I saw the program description that this was the right thing. Basically, the bracelets are simply a number of beads strung together on an elastic band. There were some letter beads, too, so I was able to spell out “SILVIA.” My wife loved it because as you can see, she spells her name a little differently than most Sylvias, and has always lamented the lack of things she could buy with her name on it. I scored a lot of points with Silvia when I got home, pulled it out of my bag, and slipped it on her wrist.

HRV Meetups?

After my talk on Saturday, a guy in his 30s (I’m guessing here) came up to me to talk about his experience with amateur radio. He had recently gone to a local amateur radio club meeting and was not received very warmly at all. He was so put off by the experience that he wasn’t sure whether to bother getting his license. Does that sound familiar?

I tried to explain that ham radio was a big hobby, and he unfortunately had just found the wrong crowd. I went on to say that not all hams were like that and encouraged him to get his ticket. Yesterday, I received an email from him that he had indeed passed the Tech test, and with the help of my study guide, also passed the General. That made me extremely happy.

Of course, he still needs to find his people. As I sympathized with him, it occurred to me that we need to create a way for hams like him to find other hams like him. I’m thinking of something along the lines of the 2600 meetups that used to happen around the country before Covid. Maybe we could even piggyback on existing 2600 meetups. I’ll be blogging about this soon, so if you have any ideas, I’d love to hear them.

Thanks to ARDC!

Thanks again to ARDC for funding this trip. The more I teach these classes, the more I’m convinced that we need to continue to reach out to this community. We need more people like the folks that attend DEF CON in amateur radio.
