  • There was a special time in the XP heyday before WiFi routers (hell, just routers even) were common for home users. Without some kind of AV, loads of folk were basically just rawdogging the Internet with ADSL modems.

    Simply being connected this way long enough at the height of the MS Blaster worm would almost guarantee a drive-by infection.



  • A third, and hopefully final attempt at getting an iredmail setup going. SPF, DKIM & DMARC all checking out fine. It’s actually working this time. Need to get the ISP to change our PTR record though, last bit of the puzzle.

    Also picked up a used negate device, so we now have pfsense fronting everything. That’s allowed me to move the original router to a better location and put it in AP mode.

    Emby media server moved off a Synology and into a proxmox container. Finally, we can stream high def with the hardware acceleration we weren’t getting before.





  • An SDR can be made to jam, even if that is not the normal purpose. Just like a kitchen knife can be used to murder people, instead of its normal culinary purpose.

    Of course an F0 can’t clone a rolling code as-is. I never said it could. But it can harvest and replay a single or multiple consecutive codes just fine, providing the original key is not used in the meantime. Only need physical access to the key while it is out of range of the vehicle.

    This alone puts the F0 on dangerous ground as an “electronic device (such as a signal jammer) for use in theft of a vehicle or theft of anything in a vehicle”

    People have locked out their original keys by messing with this before.

    The point is that our laws are reactionary, vague, and open to too much interpretation.

    If someone gets shit stolen out their car and I happen to be nearby, then I will become suspect merely through possession. Even without intent.


  • Typical BBC reporting of anything technical.

    Keyless repeaters and signal amplifiers scramble the signal from remote key fobs inside people’s homes, enabling criminals to unlock cars.

    No, they don’t. The situation described is a relay attack on keyless entry/start. Jamming is used in a two stage attack, where the device intercepts the first signal and stores it without allowing the car to ‘see’ it by jamming. The user then tries a second time.

    This time the signal is intercepted the same way, and the first signal is played back to the car from the device. The second signal is stored and can be replayed later to bypass a rolling code setup.

    It’s very niche and the stored signal quickly becomes obsolete anyway.

    Sophisticated electronic devices used by criminals to steal cars are set to be banned

    Making or selling a signal jammer could lead to up to five years

    Jenny Simms said the possession, manufacture, sale and supply of signal jammers had provided an “easily accessible tool for criminals… for far too long”.

    These devices have no legitimate purpose

    Basically, fuck you if you happen to have or build a Software Defined Radio (SDR). Again with the UK ‘clamping down’ on something that does have plenty of legitimate use.

    I use an F0 for toying with my own equipment, as an interface for my smart devices and as a general purpose keyfob. I may be arrested just for possessing it.

    The crims will not care a jot and this only serves to restrict/annoy legitimate users.

    The fault and solution lies with the manufacturers who implement insecure tech, and with the users who blindly sacrifice pounds of security for ounces of convenience.






  • Does the job & will let you pare down the menu to the essentials, move start position etc. Can also be deployed and configured by GPO, which has been a godsend.

    For the issue that you can no longer tell Windows to show all icons in the system tray, you can manually drag them out of the overflow into the visible part - or slap this into a powershell script and have it run at logon to do so automatically:

    $Name = 'IsPromoted'
    $Value = '1'
    Get-ChildItem -path $RegistryPath -Recurse | ForEach-Object {New-ItemProperty -Path $_.PSPath -Name $Name -Value $Value -PropertyType DWORD -Force }
    

    For the right-click menu being shit, hold shift before clicking, or put this one-liner into an adminstrative command prompt for a longer term fix. Restart explorer or the PC as a whole to apply afterwards:

    reg.exe add "HKCU\Software\Classes\CLSID{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve

    Snappy Driver Origin is great for obtaining up to date drivers. I’ve also had good luck pasting the hardware ID into search with site:driveridentifier.com to snag better drivers. IDs can be grabbed from device manager, under the details tab for the device properties. Example.



  • Years ago, I’d laugh at this.

    Yet it slowly becomes reality with every passing year. It’s bad enough that we’ve essentially lost pay-to-own in favour of subscription models for a lot of popular software.

    On our corp network, the amount of GPOs I’ve had to mangle together just to make Win11 usable is insane. The users are still going to have a fit in October.
