Onno (VK6FLAB)@lemmy.radioto Cybersecurity@sh.itjust.works•Hackers use Fake Cloudflare Verification Screen to Trick Users into Executing MalwareEnglish39·12 hours agoThis article doesn’t at all explain what actually happens. There’s a hand wavey description including PowerShell scripts and the clipboard, but it doesn’t indicate how the code gets executed.
The article talks about a complex and sophisticated attack, but I don’t see any evidence of that assertion.
Also, given that it’s talking about PowerShell, I’m going to guess that this affects Windows only.
Finally, there’s no source links, no CVE allocation, no indication what the URL looks like.
I’m going with deep scepticism about this report unless more information comes to hand.

Virtual Railfan YouTube channel will give you most of them.
Makes you wonder if Tesla used YouTube as a training tool.

Onno (VK6FLAB)@lemmy.radioto Ask Electronics•Is this soldered controller repairable by an amateur?English10·3 days agoI would be extremely careful, since it failed for a reason and you were very lucky not to set the house on fire, which looks like it came pretty close to.
Onno (VK6FLAB)@lemmy.radioOPto Amateur Radio@lemmy.radio•[FoAR] Foundations of Amateur Radio - The ARRL incident of May 2024, a year later #podcast2·6 days agoThe lack of transparency within the various bodies within our community is disturbing. It’s not that the information is there, waiting to be found, instead it seems clear to me that it’s been withheld for reasons nobody has ever even attempted to articulate let alone justify, and frankly I think it’s harmful to the well-being of the entire pursuit of amateur radio.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•Is there something like a spreadsheet for hierarchical data structures?5·7 days agoThere’s a whole range of cli tools to extract and query structured data like that, but you might consider loading it into something like sqlite3 and treating it as a database because those formats are really not intended for queries, they’re designed for sharing data.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•To what extent has Smartphones replaced Computers? Has Smartphones replaced Computers for you or people you know? Will Phones and Computers eventually merge into one device?1·8 days agoFor some workloads it’s true that you can do the heavy lifting on a more powerful remote machine and transport the results back to an endpoint device like a phone. Websites are a good relatable example of that, as are services like YouTube.
It’s not universally applicable for many activities that computers are involved with, data analysis, record keeping, simulations and a myriad of other processes.
Blurring of the lines between these different orders of magnitude is made possible by faster and faster networks, but that’s physically not able to beat processing done inside a single device.
The more powerful we make computers, the more complex problems we use them for. I suspect that this is unlikely to change as computers evolve.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•To what extent has Smartphones replaced Computers? Has Smartphones replaced Computers for you or people you know? Will Phones and Computers eventually merge into one device?14·8 days agoOne of the fundamental differences between phones, laptops, desktops, and beyond is size. While that sounds obvious, it also means that the amount of processing within the device is constrained by that size.
The constraints relate to how much energy can be used by each device and more importantly, how much cooling is available for the system.
It means that there’s a physical limit on how much work each device can do without being unusable.
While miniaturization is a factor, it’s not linear and you can only get so small before you fail.
So, depending on what you want to do in any given time, the device you use will dictate what’s physically possible.

Edit: Hmm … that’s odd. I just managed to check the file, two days later, and it’s essentially empty. It doesn’t appear to have saved the .mp3 file at all.
Onno (VK6FLAB)@lemmy.radioOPto Amateur Radio@lemmy.radio•[FoAR] Foundations of Amateur Radio - The Art of decoding a signal. #podcast2·12 days agoThat’s very interesting. I thought it was a once-off, but you appear to be saying that it’s ongoing. I currently don’t have HF capabilities, so I reported on a recording made by a fellow amateur.
As far as figuring out where it comes from, the direction finding can be pretty rudimentary. Use any directional antenna and determine the direction of the strongest signal. Document it somewhere, get multiple people across the globe to do it, job done.
Feel free to record them here, seems like as good a place as any.

Thank you for making this place!
It is an easy upgrade.
Boot from a Linux installer and the upgrade is seamless. I upgraded from Windows NT to Debian 25 years ago. Best decision ever.
