lT security 101: Don't leave your company laptop with authentication smart card inserted, applications open and without screensaver at your seat when using the lavatories on a train. Unbelivable...
@LaF0rge Way way crazier is this computer mouse 😅
@LaF0rge or, as we say as “Businesskasper”… Monday.
@vogelchr Das ist kein Businesskasper. Man achte auf die Smartcard im Laptop. @LaF0rge
@abdelkader_boui @vogelchr @LaF0rge Wenns die Firma für alle verlangt braucht auch ein Businesskasper ne Smartcard
@1000millimeter @abdelkader_boui @vogelchr @LaF0rge Nein, das interessante daran ist nicht, dass das eine Smart card ist, sondern nach welcher Smartcard das aussieht.
@LaF0rge have you sent an email promising cake to their whole company? That's what we do when someone leaves their workstation unlocked 😅
@lucas @LaF0rge my colleagues just sent an email to everyone to invite for a drink when they found an unlocked computer. The percentage of unlocked computers dropped drastically

@lucas

That's what we did at a previous job: Send that promise into a specially created group "Cake News".

@LaF0rge

@isotopp @lucas @LaF0rge I am still waiting for an unlocked notebook to establish this group in my company.

Damn colleagues! Hitting WIN+L every time they leave their hardware... ;-)

@lucas That’s questionable within the own company, and likely a crime if you do it on a train. @LaF0rge
@lucas @LaF0rge at university they messed with the desktop wallpaper. We had cases where it was replaced by a screenshot of itself, then icons hidden and taskbar minimized, and cases with pictures thought to be not in the taste of the person not locking the desktop… Very few persons had this happen to them twice. Less cake, though.
@LaF0rge Well, there's only honest and law-abiding people travelling in first class, so there's nothing to worry about here! /s
@thunfisch @LaF0rge i seriously like your sense of humor
@thunfisch @LaF0rge This is one of the security holes the 9/11 attackers exploited.
@LaF0rge failure on layer 8, the meat space is a tough ground for IT-security. It is so hard to teach users to do the right things. There are cultural barriers between IT departments and basically the rest of their surrounding organisations.
@daccle @LaF0rge not that I'd generally disagree, but this is quite literally equivalent to leaving a company car with company keyring on the dashboard unlocked at a highway resting area while you're taking a leak. Not hard to communicate at all.
Someone here just doesn't care.

@daccle @LaF0rge

The 8th layer should be part of the OSI model.
Do you mind if I start an internet draft? 😂

@jean_dupont @LaF0rge go for it, but I guess it is already existing
@jean_dupont @daccle @LaF0rge Layers 8 and 9 have been religion and politics for as long as I can remember. Maybe you’re looking at Layer 10.
@timoj @jean_dupont @LaF0rge then we will need a standardisation committee, since in my bubble layer 8 is and always has been the user.
@LaF0rge @daccle @jean_dupont Fine, then you can moderate the inevitable, neverending debate as to when it’s best to hold the requisite ISO standards conference in Switzerland, followed by whatever inevitable argument they’ll have with the NIST folk in Gaithersburg, provided those people still exist.
@LaF0rge Karte ziehen und kurz nen Kaffee trinken gehen.
@ccchris @LaF0rge Wieso gehen? Das Spektakel würd ich mir anschauen wollen
@ccchris @LaF0rge Nimm die Kiste komplett mit und schick Karte und Workstation separat mit insgesamt einer Grußkarte ans BSI. Dann gibt‘s ne Gaudi, das sag ich dir
@kamikadse @ccchris na das wäre vmtl wahlweise Unterschlagung, Nötigung oder Diebstahl. Nein danke :/

@ccchris @LaF0rge Wieso Nötigung?

Und für Unterschlagung und Diebstahl liegt nicht die erforderliche Zueignungsabsicht vor :p /j

@LaF0rge that’s when I do something like moving / rotating the computer. Something obvious so that they know someone did something but they have no idea what else was done.

Actual smart card. So someone else takes security more seriously than your fellow passenger.

@LaF0rge As I can see: It's a Lenovo with sensor for fingerprints. You can lock and unlock it within milliseconds.
@die_christine @LaF0rge Yes, but the user of the computer didn’t do that. The screen is clearly indicating the computer is not locked.
@stadsplanering I can see that. I only wanted to point out that locking and unlocking is so easy. I can'*t understand that he didn't do it. @LaF0rge
@die_christine @stadsplanering @LaF0rge probably not. If the previous commentors are right, then that the Laptop is a Sina Workstation that is running a custom "secure" OS.
Fingerprint is usually not supported on those. You are supposed to pull out the Smartcard which will lock the device automatically. In my opinion that is even easier than biometrics, but still doesn't help if the users don't do it.
@die_christine @stadsplanering @LaF0rge BTW since those devices are built for dealing with confidentiality material it could be even a violation of the german law to leave the laptop unlocked and unattended (if confidential material IS on the device)

@tuxflo @die_christine @LaF0rge I assume it is a violation just leaving it unlocked even if you do not handle confidential information on it at the moment. It is acting as a point of entry to the entire secure system it is connected to. 🤦‍♂️

And yes, just pulling the card out is so easy and locks it right away (had similar system on a work computer a while back).

They should also have those privacy filters installed just to limit the view of the screen.

@LaF0rge They don't care and transform every public space into the cubicle from hell. Encryption is useless with them as they spill all the beans over the air and plain old shoulder surfing and -a pair of working ears- scratch that: a half decent mic and a recording device is all you need.
@maz @LaF0rge Also people entertaining the whole train with their medical problems or relationship drama on their phone. Better than soap operas....
@LaF0rge Don't underestimate this setup of a honeypot to see what comes by..
@LaF0rge "sicher im Rechtssinne"
@LaF0rge It'd be interesting to see what happens should the smart-card suddenly be lost... 🙈
@LaF0rge 🤨 no worries, it’s just government grade authentication 🫣
@rationalgarde @metaphil @bkastl @LaF0rge
Unverantwortlich! Das Gerät hat keine Blickschutzfolie.
@qwertziop Die braucht's nicht, da Scheuklappen zur Arbeitsplatzausstattung gehören 💪
@bkastl @LaF0rge No worries. Now we are just curious, which certificate is stored on the card.
@bkastl @LaF0rge And technical equipment designed to handle information classified as restricted.
@LaF0rge Lenovo mit Sinacard und Billigmaus. Das sieht nach Standardausstattung Bundesministerien aus.
@hlux @LaF0rge Weil Mäuse laut BMVg maximal 20€ kosten dürfen...
@LaF0rge Don't worry, they probably have a dvorak keyboard layout or something
@LaF0rge Open Notepad and type "Ich soll meinen Computer sperren!" into it. Then leave it like that.
@truls46 @LaF0rge at work we tend to open playboy dot com or some such. Open landscape. They won't forget

@LaF0rge Bitte nimm den Laptop schreib eine Mail an alle@his-Company.tld mit folgendem Inhalt:

Hallo

[Company]Ich bin ein Laptop der im Zug verlassen und nicht gesperrt wurde.
Ein Unternehmens-Fremder schreibt gerade eine Mail in meinem Namen.
Jeder der auf diese Nachricht innerhalb von 5 min antwortet bekommt eine große Mageritapizza vom Absender ausgegeben.

Einen guten Wochenstart
ein Fremder

@LaF0rge Honeypot detected

(I hope)

@LaF0rge I had a lockscreen displaying a fake spreadsheet for a fake company (something along the line of ACME, but less obvious) for a while. One line at the end there was a line with the value "Curiosity killed the cat" right after "Total revenue projection FY14:". That said, I stopped using it, after realizing I take the the notebook with me even for the shortest moment ....
@LaF0rge In the ICE between Hamburg and Berlin this is a frequent occurrence .... besides the even worse habit of shouting company internals through the train ...
