Can you walk me through what the mechanism here would be? Legitimately wondering.

embedded controllers that behave in non-deterministic ways if they get unexpected data from the network

i've seen that issue with network enabled cnc controllers and time clocks

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

its because they're all piecemeal. every little fiefdom did things slightly different when they were first being built and the amalgamated monster is what we're left with today.

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

yeah someone mentioned this and we got a good laugh on it. for my part Ive had 3+ random vendor people rotating desks next to me for ages and while I know they're legit, I have no idea what they're doing

also I think they tried a social engineering voice call on me to get names of senior people and I lamely stonewalled them. either that or I made myself look like a tool to a recruiter.

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

You guys aren't going to believe this, but that guy is our games teacher.
there's a new attack on wpa and wpa2 that's significantly easier than the previous best-known one:
  • No more regular users required - because the attacker directly communicates with the AP (aka "client-less" attack)
  • No more waiting for a complete 4-way handshake between the regular user and the AP
  • No more eventual retransmissions of EAPOL frames (which can lead to uncrackable results)
  • No more eventual invalid passwords sent by the regular user
  • No more lost EAPOL frames when the regular user or the AP is too far away from the attacker
  • No more fixing of nonce and replaycounter values required (resulting in slightly higher speeds)
  • No more special output format (pcap, hccapx, etc.) - final data will appear as regular hex encoded string

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.

afaict the whole notion that warrant canaries are built on is that the government can't legally compel you to lie, and I've never really seen a reason to believe that that's true (or that it'd even matter if it was true)

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.
