A badly set up network might let the office doing mass pooling poo poo on the real time network part, especially if someone is using old hubs as a cost saving measure (for controlling 100 M€ of machinery) which is extremely likely E: also see above, yeah

apparently we've started running physical pen tests internally because a colleague had some random dude sit in the empty desk next to him an plug in a laptop mumbling something about "unblocking ports" and reported it and got a gold star for catching on pretty standard but I said I bet there are a shitload of fails because we have such a fragmented structure and revolving cast of vendors I don't know who the gently caress half of the office are anymore and nobody else does either

I don't know if they were actually testing extraction or just whether some Rando could get away with plugging in a laptop and doing stuff.... tbh thoigh I'm gonna guess that once they've got access to the lan we'd be owned pretty fast regardless

there's a new attack on wpa and wpa2 that's significantly easier than the previous best-known one:

Mr.Radar posted:there's a new attack on wpa and wpa2 that's significantly easier than the previous best-known one: tl;dr - you need to intercept much less traffic to grab the password hash. Specifically, you don't need any active users - you can get it just from probing the AP. Once you have the hash the process is pretty much the same however (dictionaries and brute force)

This is why your wifi password especially should be very long and complex. Your computer will generally just remember the password and a sticky note inside your locked house is actually harder to get at than using this technique on a weak password now.

pseudorandom name posted:I thought the whole point of warrant canaries was that you can’t be legally compelled to lie. Not sure that’s been legally challenged, yet. If you aren’t allowed to disclose Star Chamber Warrants, the act of removing that statement from annual reports *is* disclosing. But at the same time, not including that phrase is not specifically stating “We got a secret warrant”. It honestly needs to be tested in court. Personally, the fact we have “secret justice system” loving terrifies me and anything that shines a light on that bullshit is a good thing. Also, the idea the government can compel you to lie is horrific, as well.
