Onno (VK6FLAB)@lemmy.radioto Cybersecurity@sh.itjust.works•Hackers use Fake Cloudflare Verification Screen to Trick Users into Executing MalwareEnglish50·4 days 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.

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.

Are you an active LoTW user?
Onno (VK6FLAB)@lemmy.radioOPto Amateur Radio@lemmy.radio•[FoAR] Foundations of Amateur Radio - The Art of decoding a signal. #podcast2·13 days agoVery interesting! I just recorded a sample using your WebSDR, much appreciated.
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. #podcast2·16 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.

Onno (VK6FLAB)@lemmy.radioto Programmer Humor@programming.dev•When you accidental format the wrong /dev/sdX6·2 months agoThe SCSI solution requires making sure that you have the right terminator connector because of course there’s more than one standard … ask me how I know … I think the Wikipedia article on SCSI says it best:
As with everything SCSI, there are exceptions.
Onno (VK6FLAB)@lemmy.radioto [Migrated, see pinned post] Casual Conversation @lemm.ee•What's the climate like in your country?English91·2 months agoIn Australia it depends on whom you ask.
The Greens say it’s a catastrophe.
The Labor party says it’s a problem, but not enough of one to actively do anything about.
The Liberal party tell you what you want to hear, but support the fossil fuel lobby while saying that it’s not manmade.
The National party wants more nuclear power because apparently it’s “better” … for some reason that nobody understands.
One Nation blames the immigrants
The Trumpet of Patriots blame One Nation.
Fringe dwellers blame COVID, or grasshoppers, or kangaroos … it’s hard to keep track.

Onno (VK6FLAB)@lemmy.radioto Amateur Radio@lemmy.radio•Could you use a stationary array of antennas to form an image?English3·2 months agoThat you posted in this community means that I am going to assume that you understand that light and radio are the same thing. This means that anything that can “detect” light is essentially an antenna, for that (range of) frequency(ies). The Charge Coupled Device sensors or CCD sensors are in common use in digital imaging, it’s an integrated circuit that can detect light. Or said differently, a CCD can detect radio waves at light frequencies.
In other words, a CCD chip is an array of antennas, that do what you describe.
I’m not sure what a densly packed array of nanoscopic antennas brings that isn’t already solved with a CCD.
CCD’s are also used outside the visible spectrum in all manner of places.

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.
