  • It kinda depends on the setup I think, especially when vlans and firewalls are involved, you’d likely need additional payloads to make further progress in that kind of environment IMO. Something granting persistent remote access to the compromised machine would be the most ideal option.

    As always physical access is pretty much game over though lol.

    My cams are only accessible via an authenticated endpoint hosted on a dedicated machine, which acts as a “bridge” between the VLAN that the cameras are on (no internet access), and another VLAN hosting internal services, like home assistant, plex etc.

    Aside from physical access, the only way to access the cams (that I can think of) would be via some exploit in Home Assistant, or by brute forcing the password to (any of) my network switches to access the management VLAN, changing the VLAN the cameras are set on to something else (bypassing the routing, firewall setup, and auth “bridge” entirely). Or maybe just exploiting the bridge machine directly and dropping a payload to forward the cams out to the net via the services VLAN

    With physical access, you could chop up the PoE for an external camera and using that as an ingress point - but you’d only have access to the cameras and the bridge machine unless you exploited that too. At this point the zabbix client on the bridge machine would have notified me that a camera’s dropped off the network, unless you dropped a payload to force it to return a good status lol

    Does sound like a very fun exercise though tbh



  • I think most people are just used to Google, I used to be several years ago before moving to DDG.

    Now I find Google is way too… “tutorially” and “bloggy” with results, and actually slows down my workflow a lot when I’m looking for a specific thing immediately - usually a bit of scrolling to get what I’m looking for.

    DDG (for my use case as a casual search engine, and something to search docs for work) gets you to whatever you want with a much, much shorter and concise query, and pretty much always gets it right each time as the first result


  • I agree with OP here, these results are not great.

    OP searched for the redis docker image, not a tutorial on how to use it, not a tutorial on why redis should be run in docker, and did not search for redis docker docs. While these are relevant, they should be further down, not the top result. DDG gets this right, and I’m pretty sure other search engines do too.

    For a total newbie, these results are probably OK, but for a technical person who knows what they want literally as they type it, Google’s results are (excuse my french) simply shit. DDG is miles better at handling this stuff, and they don’t need your personal data to do it well either.

    Edit: Just went and searched “redis docker image” in a private tab on Google, and the docker hub image for Redis is not even shown on the first page of results














  • Dang, that thing is the bees knees!

    Would make more sense to replace just the batteries rather than the whole unit IMO. Looks like it takes standard 12v 7Ah sealed lead acid batteries, so should be doable for under $120 (if you buy them individually and use the existing battery harness)

    I have three other UPSes, but none of them are as good as yours lol:

    • APC SUA1500RM2U - was a great online rackmount unit, stopped using this a few years back because of its tendency to overcharge batteries without a charge controller ADC calibration mod. It wrecked my last battery pack bad 😭 plan to convert it to LiFePo4 and put it back into service 🤞
    • Zigor Ebro - cheap and cheerful line-interactive UPS for the modem, network switch and CCTV cameras. Switchover time is pretty much instantaneous, worth every cent paid and has kept my network up through many outages
    • Cyberpower UT650 - A temporary offline UPS to hold the server gear specifically until I get the APC back in service. Honestly not worth the cheap price, the switchover delay is long enough to shut off anything that’s not a server PSU with massive bulk capacitors

    Edit: fix bullet list formatting
