back to article Work experience kids messed with manager's PC to send him to Ctrl-Alt-Del hell

Welcome to another installment of Who, Me? It's The Register's Monday column in which you confess to crises you caused, and the course corrections that cured the chaos. This week, meet a reader we'll Regomize as "Curt" who once worked as IT security manager at a company where the helpdesk manager routinely ignored company …

    One place where I worked, a favoured prank to use against people who left their machine logged in and unattended (against policy) was to take a screenshot, set this to be the desktop background, and remove all the real icons, so that you could have a laugh at them clicking on 'icons' and wondering why nothing started up.

    Also, you could rotate a windows desktop 180 degrees with a certain keypress (I cant remember what) and leave them puzzled.

      Yeah, that's pretty much the same thing that people in my old office used to do, too. It got you to really remember to lock your screen before leaving your desk.

      As for the screen-rotation trick, I believe it was CTRL+ALT+(arrow keys). I think the 180° one was up arrow. You could turn the screen on its side if you did it with left and right arrows, too. A lot of frantic calls to service desk would ensue because someone would do it by accident and then be confused about what they had done. Was pretty sure that it lasted up until Windows 10.

      Certain colleagues of mine did that to one another at one place, should the "thou shalt lock screens" edict go overlooked, to the extent you'd call it an arms race.

      Nom nom nom

      At a previous workplace my team's preferred method of reminding colleagues about locking PCs when away was to send an email from their account offering to buy the whole team doughnuts. This worked great as it happened rarely, nobody minded buying the doughnuts much, and the rest of us definitely didn't mind eating them!

        Re: Nom nom nom

        Back in the day, we were on Unix server (10 people per) and once when a coworker left hers unlocked, I sshed to a different server, and set up a cron job at various times to email herself a message ("Hi, how are you?"). At times she was sitting at her desk and got that email from herself.

        It kind of drove her insane because she couldn't figure it out. When she threatened to go to security and tell them someone hacked her account, I fessed up what I had done.

      I used to do the wallpaper/desktop background trick and the screen rotation trick on unattended/unlocked PCs/laptops. However, many changes of company ownership and management meant IT policies look just as unfavorably upon messing with another user's PC as on someone leaving it unlocked. Nowadays, I resort to hitting Winkey+L and sticking a Post-It note to their screen with a drawing of a padlock to give them a subtle hint about policy.

        I open Notepad and say "thanks for leaving your computer unlocked. I've deleted some of your files, had a browse at the confidential ones in the shared area you have access to, and had a good rummage through your emails. I almost sent an "I QUIT" email to your boss, but didn't on this occasion.

        Then lock the machine so they have a nice surprise when they unlock

        2. Already?

          Was usually quite diligent about locking my laptop when away from my desk but once popped next door for a literal 5 second chat with our boss, which became a discussion on something and then something else and eventually ended with him guiding me to the Sandy Denny CD* that contained her BBC session recording of Solo, as opposed to the version with Fairport. I’d been trying to find it for years, on and off. Got back to my desk and unlocked the laptop to find a very blunt message in Notepad from our chief techie advising me of various unpleasant and unnatural experiences that might befall me next time he found my laptop unlocked and unattended. It worked, although I like to think it was unnecessary.

            I commend your musical taste. In our office an email professing undying love and lust to the prettiest (or not so depending on one's mood) female colleague was de rigure. Alternatively 10 lines of 'I must not leave myself logged in' to the boss worked well.

            1. J. Cook

              We actually have a sensible policy (with group policies to back it!) that enforce a five minute idle timer for the screen saver, which also locks the console.

              It's built into one of the minimum internal controls that governs how the place operates as well, which is why it's enforced unless you have a REALLY good reason why the workstation shouldn't have the screen saver kick in (digital signage, other specialty apps, etc.)

      Screen rotation

      Screen rotation was done with

      <CTRL><ALT><ARROW KEY>

      Left and right were 90 degree rotation down for 180 and up to correct

    6. billyrubin

      Using the hot keys to rotate the screen was a common prank in my office a decade ago. People figured out quite quickly how to resolve it.

      So of course we upped the ante. I took a screenshot of my colleague's desktop, rotated it manually in paint, opened the image in chrome, used F11 to fullscreen it, then finally used the hot key rotation.

      I remember watching with glee from a distance, as he thought he finally had it sussed, and started loudly and awkwardly turning his monitor upside down.

    7. F5MegaZone

      I've done exactly that too.

      Also, back in the VT102 text terminal days if someone left themselves logged in, a common prank we'd pull was to edit their .login file to add a random timer that then called logout. So they'd login and, ad some point, their session would just end.

      Crueler was to alias commonly used commands to other commonly used commands, or to alias the command to add lots of flags, etc.

        Facepalm

        Re: Lock screen

        Going back to the 80s and 90s, on a Mac you could do a lovely trick on people. You just needed to create a new folder (or anything) in a folder, then "select all" and drag everything down and right, unselect everything, then move your temporary icon to the top left of the window, then select all and move again until everything was well and truly out of sight. Then delete your temporary item.

        As the icon locations and window scroll location were saved, everything persisted so the user could open a folder and find ... NOTHING ! Usually panic ensues until eventually they spot the scroll bars - but it means moving both of them before any files return to view.

        Re: The horror... the horror...

        Mild. At one place I worked, a small cowboy outfit loaded with "good 'ol boys" looked forward to people leaving their screen unlocked.. You'd return to find your screen locked, and your background image changed to a rather large, muscular black man wearing nothing but a smile, showing an unusually large sausage. A juvenile place to be sure, but the money was good. I was never caught out, already being in the habit of locking upon standing. The place I worked at before that one was a professional organization. They would write you up, with a second writeup being a fireable offense. Now I work from home, and it doesn't matter if I leave things unlocked.

    The classic i remembered (i grew up with Windows XP+):

    Screenshot, rotate image 180 degrees, set as background. Remove all icons, hide taskbar. ctrl+alt+down (this rotates the screen 180 degrees). Bonus points if you flip the screensaver too!

    Classmates appreciated the pranks for the most part. Teachers didn't like me, i wonder why!

    In one job, I shared an office with 2 of my best mates. It was a great project, and a great team. But if you did leave the office without locking your computer, you would almost certainly come back to either a) Your screen being upside down or at 90° or b) if you were foolish enough to leave it for more than a few minutes - You would come back in, and 30 mins later, one of the guys would turn around and say "Wow L, that's a really nice email you've just sent. I really appreciate the kudos, although look I'm not interested in more than just friendship, ok...?" A quick check of sent emails would show an email having been sent praising the colleague and suggesting a bit more...".

    It was all a good laugh between us, but it only worked because we really were best mates. I'm friendly with my current office colleagues, but no way would that work out here... ;)

        We awarded 'The Pen' for the most stupid act or comment so far recorded. You could only pass it on if another person made a cock-up of equal or worse stupidity.

        It was actually quite a good pen, from a competitor, complete with logo, but it would randomly stop working. Nevertheless, it had to be on display and be used. It was very embarrassing to be awarded this prize. The threat was sufficient to ensure actions and words were considered before rash action. Our Sales Director had it most of the time.

        We created a book containing phrases that defied explanation ("We're going to come up smelling on this one....")

          Maaany years ago I heard of a similar thing with repmobiles - a.k.a. company cars for the sales reps.The story went that the reps didn't really look after the cars all that much, and there were many (mostly minor) bumps. The company bought an old Lada or Skoda - back in the days when there was a joke "Q:what do you call an open top Lada ? A: A skip !" The rule was that if anyone had a bump, they got the old wreck - either for a month or until someone else earned it. The accident rate halved immediately !

      "Switch to a non-western language, making it a pig to switch back"

      You had half a chance if the language used the Latin character set. Thai was enough to grab another Nokia and use that as a pilot or guide. :)

      The screens of the local transport (~Oyster) card recharge machines have the language selection button close enough to the balance or recharge button that half the time when you intend to recharge you get the first language after English which happens to be Vietnamese.

      It couldn't be French or German or even Occitan ? :) To be fair Vietnamese is probably the most requested language given our demographics.

      You just have to cancel the transaction and let the machine return to the default. I have tried navigating in the Vietnamese mode but I could swear the layout and options are different.

      Actually for most people it is now a non-problem as they can use any credit or debit card instead on the buses etc or their phone's digital equivalent.

        That definitely used to be the case on certain cash machines around here. The default English layout had intrusive adverts and graphics, the Welsh was simple and uncluttered. Not so much these days.

        It's amazing how many cashpoints and self-service supermarket tills are still English-only. There are exceptions that offer Welsh and usually at least one other language (Polish used to be common) but it's far from being the majority as far as I can see.

          Language selection on ATMs is often driven by the BIN code of the card that is inserted. In the late 90s I wrote the bit of code of a large UK bank that would look up the BIN and set params that would then drive the language options displayed to the customer. IIRC we held about 12 language sets to select from.

          Just because you don't see the other languages doesn't mean they aren't there. English and Welsh was a default option on all machines in Wales and could be enabled on those machines in the border regions where you had customers who wandered over the border.

          Is that lawful that cashpoints and tills are monolingual in Wales? Welsh Language Act?

          1. Martin an gof Silver badge

            Re: Old Nokia phones

            The Act only applies in that sense to public bodies. Private companies are given a choice, but there is often a lot of local pressure (some time ago I posted links to several stories where staff at Sports Direct and Trago Mills had to stand up to bosses who were dismissive, indeed in one case had sent a memo banning staff from talking Welsh even when on break) and it's difficult for a large business with all of its signage-producing staff probably based in London or Manchester or somewhere similar to get things right, hence the problems in Cornwall. People around here (Swansea) got very confused when the self-service tills for "Smaller Shops" and "Larger Shops" at the local Sainsburys were labelled "Ychydig o Neges" and "Llawer o Neges"; quite literally "a little of message" and "a lot of message". It turns out that in some parts of north Wales "mynd am neges" ("going for a message") is the equivalent of "running an errand", but I don't know anyone down here who uses it. It might have been more understandable as "Neges Fach" (small message) and "Neges Fawr" (large message) (or "negeseuon" = messages) but still, the tills themselves do not have a Welsh option, unlike the ones in Morrisons which not only have Welsh on-screen but also have a Welsh voice-over.

            Cornish and Welsh and Breton are from the same "branch" of Celtic languages so bear a lot more in common with each other than they do with Scottish and Irish Gaelic/Gallic and Manx. With Cornish it is exacerbated because the repeated attempts at reviving the language since the 1970s have of necessity drawn a lot on Welsh in particular due to (a comparative) lack of written and recorded evidence for Cornish, and a desire to "modernise". My (Welsh-speaking) offspring find the currently favoured flavour of Kernwek quite "ugly".

    I remember that sequence was called the Secure Attention Key (SAK) under NT4.

    I think it was originally a mainframe thing but the idea was the SAK was certain to get you back to the monitor etc and could not be reassigned or intercepted.

    I don't think that was necessarily true of later Windows.

    I guess if you don't use a SAK secured screen locker you get the SACK.

    Before PCs were commonplace in offices (in fact, when offices had shared phones), the place I worked had a strict clear desk policy. We worked with confidential drawing and specifications but, since we worked closely with the manufacturing areas, the office wasn't within the more secure part of the site. There were always staff present during the day and visitors weren't allowed to roam free, but when you left for home at the end of the day, your desk had to be clear - by that I mean NOTHING on it. All paperwork, including filing trays, had to be put into secure cabinets, the keys of which were taken away by security. Desks drawers had to be locked, too, but only personal belongings were allowed to be kept in them. If you didn't clear your desk before leaving, it would be cleared for you - and you would have to report to the department head to explain why you were about to go to security to reclaim your work. One strike and it was a verbal blasting, two strikes and you said goodbye to any annual bonus, three and it was external redeployment!

      I have a little file called desktop.exe from 2003 which has a gatling gun amongst other effects, great if you want to take it out (virtually) on your screen. Letting the termites out and the machine gunning them leaving little red splotches was fun.

    One of my colleagues got physical

    Many years ago in the CRT days, he took the back off one. Loosened the scan coil clamp and slightly rotated them, then put everything back together. The individual who's machine that was done to was a general pain in the arse to just about everyone in the company - including the maintenance bods, so it took a surprisingly long time to find and fix the erm... fault.

    A colleague (and good friend) of mine had a Penetration Tester in for the day as part of an ITHC. They were both working in a meeting room. When they went to get a coffee I noticed said colleague had left his machine unlocked. I took the opportunity to find the Rick Astley classic on YouTube, turn the volume up and press play. I left the room and shut the door behind me. I lurked within a suitable distance to see his reaction when he came back with the Pen Tester and openend the door! "Never gonna give you up...."

    "Burting" people was my favourite thing to do to unlocked and unattended desktops.

    Open browser, navigate to Google, image search for Burt Reynolds and find the image of him lying naked on the bearskin rug or whatever it was, set as desktop, lock and walk away.

    It never made people behave any differently but it was funny nonetheless.

    My favourite was to go into their Word and add in a few autocorrect tweaks: from a little misspelling adjustments (and turning off the spellchecker), or inserting a derogatory nickname in inverted capitals mid name, or maybe changing the default corporate sign-off. Swapping mouse buttons; adding a captioned screensaver; the classic wallpaper lock screen as described; or if they never left the PC unlocked, simply shifting all the number keys along one and moving the '0' to first place - ah, the good old days.

    Company where i worked also had a clear desk policy, plus it was a serious offence to leave your PC unlocked when leaving the office as there would be contractors and visitors wandering round the building.

    Our favourite trick was to go onto the computer and put passwords on all the top level directories in a user's personal filespace and / or generally move all the files around.

    Another Post It would be hidden somewhere in the office telling how to undo what had been done.

    A Post It message would then be left on the PC demanding payment of a ransom in cakes and biscuits to be left at reception in the building after which a phone call would be made to the receptionist (who was in on the game and liked cakes) telling the unfortunate where the unlock post it was hidden.

    We got quite a lot of cakes before management forbid the practice after someone with a negligible sense of humour complained.

    I'm going to be boring here...

    At my place of work if somebody uses a computer that is logged into another person's account then both they and the logged in user would be subject to a security investigation, the initial phase of which will involve their account being locked and removing their access to the IT system.

    Not only that, but unauthorised access to a computer and unauthorised modification could be seen offences under the Computer Misuse Act, which could have negative implications for your IT career.

    Maybe instead of pranking somebody it would be a better idea to just press Windows-L.

        No, you need to ensure they never do it. Insuring it is pointless, just resigning to repeating and replacing stuff repeatedly.

    Evil pranks

    Back in the late 90s a colleague used to leave his PC unlocked and unattended when he went for a fag break or a visit to the loo. So, one day I installed some remote control software (in the days before such were picked up by AV systems) and waited for the opportune moment. That moment came when we had a visit from the company CEO over from the USA. I waited until the office touring CEO was on the other side of the partition from my colleague and then remote opened a browser and started opening porn sites. My colleague spent a FRANTIC 30secs closing windows only to realise that more were opening all the time, at which point he demonstrated a high level of intelligence and switched off his monitor and went to the loo, presumably to scrape out his underwear. When he came back the CEO had moved on and his desktop was back to normal, but he knew he'd been had and soon found the software. I held my hands up and after a stream of invective that would make a sailor wince, he finally laughed and forgave me. No, he NEVER forgot to lock his desktop after that,... and neither did I,.... because I really didn't want to find out what his revenge would be. <LOL>

      Bluetooth mice are also handy for the mirror prank of moving the mouse and clicking random icons/links, doubly so if the victim machine has a USB port that is discretely tucked away in some non-obvious place (monitor USB hubs or dock stations for example).

    I'm not aware of any pranks, but a close friend used to work for a big tech corp, and they had set things up so that if your workstation remained inactive and unlocked for a sufficiently long time, it would lock itself - and start playing loud music.

      RA by TWD by any chance?

      I have very fond memories of Remote Anything from TWD Industries. It was super useful, for both legitimate and humorously nefarious purposes. It had a 'hide the icon from the System Tray' option. Lovely.

      Sadly Symantec, who had a competing product, PC Anywhere, decided to add Remote Anything to their virus list, and pretty much ruined TWD overnight. A shame. Peter Norton Computing was a great company. Symantec, not so much.

    Only

    Admitted it was a "great prank" when it was pointed out of his security failings and that he'd be in more shit for that.

    Because I had something similar, to a, lets just call him what he was, "a cunt", engineer who liked giving people nick names. However, when I did the same to him and quite expertly stuck him on the front of Time Magazine "Jim in Bung Scandal" and sent it to 3rd line as I knew they'd find it amusing, he went mental. Ranting and raving, explaining it was slander. I pointed out, if anything, it was satire and mainly "No one is going to believe you were ever on the front of fucking Time Magazine". He, with a serious tone said "They might think its real". He still said he was going to put in a complaint until I pointed out the photo he'd done of another engineer and the name he always called him.

    He eventually said "It was quite funny". I knew, he didn't believe that, he just knew he'd be fucked if he'd complain.

    Thankfully he's now dead and I'd have quite happily pissed on his grave but I couldn't be fucked to go to his funeral because, he was a nasty cunt.

    Got caught

    Was funny when done to me to my home machine by a decent engineer who actually taught me stuff instead of being an unhelpful dick.

    I'd left my laptop unlocked and another engineer and I had worked out how to sneak over the network to remote to home without the traffic being spotted. This was 20 years ago now. I'd left it unlocked and connected to my home desktop. I came back to my desk none the wiser. Wasn't until about a day or two later when using my PC at home I noticed icon names have been changed to Cock, knob, wanker etc.

    He said "That will remind you to lock your desktop next time".

    We always had a rule, no pranks that stopped you from working.

    Unix (ish) prank

    30+ years ago when I was in grad school I used to hang out with a few friends I knew from Engineering (I was in Comp Sci) late Friday afternoons when their student lab had closed for the day. They used Apollo Domain workstations, which ran something that wasn't Unix but presented itself to the end user as essentially Unix with a GUI layer on the console.

    One of the guys would also leave to go to the bathroom without locking his screen. It wasn't really a security issue since it was just us, but I viewed it as an opportunity for a prank. I wrote a small script that would swap names of the files/directories in his home directory. I took care to have it skip a few that would cause problems if they were moved (I don't recall the details) and had it set to run when he'd login at the console. The idea was that when he logged in it would swap things around, but the next time that swap would undo it all and everything would work correctly. He went to the bathroom and I told everyone else what I was doing and set the trap.

    We usually went for pizza around 5:30 and everyone logged out so when he logged back in we're all watching out of the corner of our eyes. He starts saying his workstation is borked and we're all keeping a straight face so one of us suggests he try logging in again so he logs out and back in and everything is working. We're like "wow that's weird, trying logging out and in again, maybe there is a problem of some kind" and of course then it is broken again. One of us wasn't able to suppress his laughter at this point so we confessed and he became better about locking his screen after that.

    Most of these tricks are for picture-book computers. Back in the days of amber text-only, my screen was visible from the hall so everybody knew if I was in or out. To muddy the water I prepared text "screens" such as Lotus 1-2-3 (release 1a) and Word Perfect{DOS} 5.1 etc doing typical spreadsheet and document work. An un-changing screen would be a giveaway so I programmed it to rotate the screens every dozen minutes. (Peeking) No, linger-time configurable on command line. (Peeking) No, it was WP 5.0 (Peeking) I see I included News Of The Day: "AT&T NEWS RELEASES *** AT&T and GE Information Services (GEIS) today announced interconnection of their electronic mail services, allowing thousands of both companies' e-mail customers to exchange messages for the first time.

    Did this to my boss once, screen shot of desktop so it looked like his PC was not locked and changed the mapping on the keyboard for good measure. When he determined someone had played a trick on him, he couldn't use the right keys to unlock it.

    Another time, another company, another country, I adapted an email and put it in the Sent folder of a colleague who worked with an important client, so it looked like the mail had actually been sent to that client. The email professed her undying lust for the client contact, both females, with my colleague professing that, despite being straight, she had feeling of a certain uncontrollable nature for her. Understandably, my colleague freaked out, she was known for this, which is why she was, ahem, targeted. Unfortunately for me, she turned it 180° when she, the client and the deputy managing director got in on the joke and I was marched into his office where I was threatened in no-uncertain terms with being immediately sacked because of a client complaint. All this while the client and my colleague were outside laughing.

    Less IT related - when I worked in the UK, a colleague who was constantly meeting clients and loved giving said clients business cards, had one of those wallets that were quite long with only card slots, in which he only had business cards. A few of us substituted some of his business cards with certain other business cards most often stuck to phone boxes and that advertised certain services. A week or so later he came back from an important client meeting in which the client was bemused when he handed him a card advertising "Mandy's services". Luckily for him, the client had a sense of humour, as did he, so a good laugh was had by all.

    I always used to lock my PC/laptop when not at my desk, but got fed up with my manager always banging on about it, so I set my lock screen saver to a screen shot of my unlocked desktop just to piss him off. Petty but gave me great satisfaction when he tried to prank me.

    It did confuse some of the IT support guys though which I feel bad about.

    Years back, I was doing tech support, and was also a massive fan of the open source remote desktop system, VNC.

    I worked in a University computer lab. We have about 50 PCs, and 1 Power PC based Mac.

    My boss managed both staff and student support, and his office was a couple of floors down. I was (and am still) friends with the technicians who did staff supoprt, and they were based in his office.

    One day, we were going to lunch, and my friend came up with an idea. He asked me to install the VNC server on the Mac, put an out of order sign on it (to prevent the students using it), turn the monitor off and give him the IP. He also asked me to disable power saving.

    Then, when our boss went for lunch, he leapt on the boss's PC, installed the client, connected it to the Mac, and made it full screen.

    When the boss came back, he was rather confused to find that his Windows NT 4 desktop had apparently been replaced with a desktop he didn't recognise (he was one of these people who viewed Macs as a a waste of time, so never bothered to use one).

    At a place where I worked (a long time ago!!)...

    Someone devised a Mac init that reduced the screen size by 1 pixel in each direction every time you re-booted the machine. It took a while, but the screen shrank ever so slowly, and since it was gradual, it wasn't noticed for while. Eventually the victim wondered aloud (or some such), and the jig was up. Removal of the init was all it took to restore screen size.

    Yes, this was back in the 68k era of Macs, a long time ago!

    Back in the university, our cs department had far too few terminals for students (this was early 80'), so if you got away from one you were supposed to log out and give someone else a chance to get some work done. There was this quite strange guy who always left his session open while disappearing for some indefinite time. Finally, we got fed up with this and moved all the files in his home directory to a directory named '...' ...it too him some time to figure it out. You get what you ask for...
