Hackrf Portapack H2 Mayhem
Jayme Bostic
Enter MAYHEM, an evolved fork of the original PortaPack firmware that the developers claim is the most up-to-date and feature packed version available. Without ever plugging into a computer, this firmware allows you to receive, decode, and re-transmit a dizzying number of wireless protocols. From firing off the seating pagers at a local restaurant to creating a fleet of phantom aircraft with spoofed ADS-B transponders, MAYHEM certainly seems like it lives up to the name.
There are many ways that promoting mayhem in a horrifically oppressive regime is not responsible use. For example, where it would have a disproportionate negative impact on people who are not part of the regime.
So far the only reported legitimate uses in these comments are consistent with behaviour that the relevant regime would likely approve of (see comment on testing fire service pagers). So not really a good match for the name MAYHEM.
I agree its encourages the malitious potential but that potential/inspiration is why everyone wants to code like this and the message he sais only provvokes the ambitions into the possiblilites in the readers imagination to get a clear idea of not what your supposed to do but what you can do and anyone smart enough to wantt to learn coding and this already knows and or have decided how diverseley useful electronics are and have already chosen what they want to do weather it be prottecting servers encrypting building programmed phisical useful interesting funny and or cool or people have already decided to be a nuissance but nowone smart enough to want to learn electronics or the possiblilities of it already know that there are bad possiblilities this isnt kidergarten forced perspective snd and ideology brainwashing
I use this product to help find exploits against vehicle security systems and then I form the manufacturers. Less then 10% of what I find do I share because I find so many rolling code vulnerabilities with this tool. We do try to inform manufacturers though. I also teach people how to use this tool to under stand RF and how to make safer products. What do you do to make the world a better place other than judge people. This is a great tool they share for free.
TBH, any scenario with less extreme storylines involving RF attacks could be used. i.e. Bank Heist in which you have to perform or defend against attacks on your get away vehicle to defeat the scenario.
In an alternate, simplified reality with Boolean ethics, the other things you mentioned may not have ethical uses, but in this reality they do. Fighting back against an oppressive and murderous regime is one obvious use.
Lots of legitimate uses. A field engineer needs to transmit a specific signal on command. Load up that signal, go to the site, press the send, tada you have a test signal 100 miles away from an outlet.
Key fobs and garage door openers fail. Maybe you can get a signal 1 out of 50 times, and the retail key fob learning ones need things more reliably, well this will record the one time the old fob worked, and this will transmit reliably.
I am seriously tempted to get it and mostly use it as a garage door remote. Since it is a SDR, I could also use it in the car to just listen to various frequencies. Depending on my mood, I could listen to AM, FM, Ham Radio, Air traffic when by the airport, etc.
Read the original linked article, it includes a list of ethical uses: capturing RF autonomously to study it later, check the resistance of your wireless home appliances to replay attacks or conducting security testing on devices where you have permission to transmit.
I use this to break in to my own cars. I love the idea that by a codes and scripts you can get into things by using the back door. I love my hacker one portapack., I want to thank great scotts and the maker of mayhem yous are awesome
I go a PortaPack for my Hack RF One simply because it lets me see the invisible spectrum that surrounds us all. I have no specific use and certainly no malicious one. My PortaPack came with Mayhem pre-installed.
-mayhem/releases/tag/v1.5.0
-mayhem/wiki/Won't-boot
My device wont start up
White screen
If you device won't boot and leaves you on white screen, then you will need to power off the device and then hold down the UP button while you power it on. This could take up to 10 seconds.
Black screen
If you device won't boot and leaves you on a black screen, then you will need to power off the device and then hold down the LEFT button while you power it on. This could take up to 10 seconds.
Could you please update on the status of the pull request/fork for the Mayhem firmware to support the WM8731 audio chip? I would like to see this solved because otherwise I will return the portapack and order a version that supports the regular firmware.
Tks BG7IYN,
But I'm unable to select these spans.
Probably I've mispelled the question:
my firmware is V1.3.1_wm8731
I wonder to monitor a larger Bandwidth (SPAN) whit SPEC Mode.
In this release I'am able to have only 5M SPAN
Can you help me to understand how to select larger SPAN?
TKS
I have seen the video
I use SPEC for finding interference in WiFi networks. To identify the waveform I need to close the span to 1 Mhz o below. In some cases, it could be usefull to have a wider Span to analyze different situation.
My HackRF is working, I can use it separately with other software such as gnuradio-companion. But when I use the above firmare and plug in the portapack, the blue lights come on and the screen stays off.
The switching regulator (TPS62410) on my HackRF booard burned up. Ieed to test this Portapack board to make sure it will not hurt my new HackRF One board. Trying to test with bench supply, but I cannot find a schematic and do not know how to supply power to this Portapack board. Is there a schematic anywhere for this? How can I make sure it will not hurt my new HackRF board?
