I find urh a great tool ... except when you absolutely have no idea what kind of signal it is. I usually use inspectrum as a first tool to have a basic idea what the signal looks like. Based on that, I decide how to go further.

Inspectrum is an older tool and has less features then urh, but sometimes simplicity works better.

interesting advice. Thanks!

I do not see that as phone-usage, I'm doing an experiment to see how easy / difficult it is to revert the "i need to know the time, so I grab my phone" reflex back to "I need to know the time, so I look at my wrist".

I'm currently reading some books on how easy it is to manipulate peoples behaviour using 'nudging', this to better understand the social engineering tricks used by hackers.

An chapter in one of these books in how social media use tricks to manupale our behaviour that resemble the tricks used by the gambling industry.

One of the things I find intriging is the size of a smartphones today. If you look at it objectively, they are actually so large that most people would consider it to be annoyting: you have to carry it in a bag, in a pocket of your pants -but you have to take your phone out when you want sit-, or ..you carry it in your hands. Have you noticed how many people have their smartphone in their hand when they walk around? But, of course, if you have something in your hand, it is very easy to open it quickly check your notifications; which reinforces the addiction.

So, that's the thing. People do not find it annoying.

So .. as an experiment, I am trying out how easy / difficult it is to break the habbit.

A small sidenote when (or if) I manage to get my garmin vivosmart HR charges, it does rapport activity per week, number of steps and number of floors I went up on foot per day, even without a smartphone app. So that's at least something :-)

One of the reasons I am looking for a new sportswatch is because I try to reduce my smartphone use and I noticed that I actually took out my smartphone just to check the time.

I have an old garmin vivosmart HR but I do have a problem with the charging cable. Plus I am not able to download the healthstats with my linux 'daily driver' laptop.

Perhaps I should just get a cheap regular watch somewhere? 🤔

I don't. I thought the emoji would have made that clear.

I have been doing cybersecurity awareness lately. We are starting to get over the furst hurdle: make people see the signatures of phishing message. But now we are starting with the 2nd hurdle: make people understand that when they write a genuine post, they should avoid these signatures of phishing, in this case, the "time pressure" argument.

The problem is that the more genuine messages have phising signatures, to more difficult it becomes for people to distinguish a genuine posts from phishing. There is also the risk that you genuine posts will get noted as fake (although that is clearly not the case here :-) )

ah .. currently not available :-/

[–] kristoff 8 points 11 months ago (2 children)

ah. That looks very interesting. And they have a show here in the EU, and it seems to work with gadgetbridge (thx Lambda RX :-))

Thanks!

[–] kristoff 1 points 11 months ago

my daily driver is a ubuntu laptop so I was first thinking about that, but now that you mention a mobile app, ..yes. that would be nice too.

thanks for the food for thought :-)

A URL 'Free up to some-end-date'. ???

Phishing link? 🤔

[–] kristoff 2 points 11 months ago* (last edited 11 months ago)

Hum , interesting point. If you are a hacker, would you not prefer software to be spread out everywhere so people would be even more confused what is the real source for some application?

I guess people would then just depend on their search engine

[–] kristoff 2 points 11 months ago

Well, in principe I do not see that much different between 'curl | bash', 'sudo apt-get install' or installing an app on your phone. In the end, it all depends on trust.

Considering how complex software has become and on how many libraries from all over the internet any application that does more then 'hello world' depend, I do not see how you can do if you are not prepared to put blind trust into some things.

Concerning CrowdStrike, I am just reading an book on human behaviour (very interesting for everybody who is interested in cybersecurity), and I am just on the chapter about the fear of deciding with unknown parameters vs. the fear of not deciding at all. Any piece of software will brake at some point, so will you wait forever to find something that will not have any vulnerabilities?

Obtainium seems to have a very interesting take on this. Thanks for the link! I will check it out 👍

Hi all,

Small question. Does anybody know if there already exists a lemmy community on disinformation (in the infosec area or more broadly)?

Thanks! :-)

Hi all,

Had a small chat on #AI with somebody yesterday, when this video came up: "10 Things They're NOT Telling You About The New AI" (*)

What strikes me the most on this video is not the message, but the way it is brought. It has all the prints of #disinformation over it, .. especially as it is coming from a youtube-channel that does not even post a name or a person.

Does anybody know this organisation and who is behind it?

Is this "you are all going to lose your job of AI and that's all due to " message new? What is the goal behind this?

(Sorry to post this message here. I have been looking for a lenny/kbin forum on disinformation, but did not find it, so I guess it is most relevant here)

I do not think this has already been mentioned. As I guess most of you are also an mastodon (or another fediverse-enabled playform)

Hi,

I don't know if this has already been posted here.

Some time ago, I found this 3-part documentary on the cyberpunk genre:

Part 1: https://www.youtube.com/watch?v=sttm8Q9rOdQ (also in the title of this post)

Part 2: https://www.youtube.com/watch?v=0VoX3vr6CCM

Part 3: https://www.youtube.com/watch?v=KczJNtexinY

Enjoy! :-)

HI all,

For people who live in the neighbourhood of Hanover, Gernany. In almost 3 weeks from now, I will give a workshop "Hacking Radio-signals" in the summer edition of hackover 2023. The exact timeslot still has to be decided, but hackover is the weekend of 14, 15 and 16 July.

In the workshop, we will capture, analyse and decode the signal of a 433 MHz remote-control. You do are required to bring your laptop and have some software installed beforehand.

If you are interested, either drop a message in this thread or contact me at the email-address in the announcement

Are we there yet? (self.cyberpunk)
submitted 2 years ago* (last edited 2 years ago) by kristoff to c/cyberpunk@lemmy.villa-straylight.social
 

Having to deal with cybersecurity from time to time, I get the impression that reality is more and more turning into a real cyberpunk dystopia.

OK, we do not have flying cars, spaceships or offworld colonies like in blade runner, but we do have

  • hackers, state-hackers, hacktivists, ... sometimes disabling complete industries
  • There is a rise of AI
  • There is to power of big companies (like the big tech companies) who control the thinking-process of millions (although they do not yet have mercenaries)
  • there is the all-connected internet, without which devices stop working.
  • there is the influence of regllious minorities
  • there is not yet that much cybernetics in the sense of people walking around with augmentic implants, but the science of microbiology is doing some very crazy stuff the last couple of years with DNA and CRISPR

And there is Climate change that is looms over everything!

Any comments or thoughs?
