Welcome to another Who, Me? confession. Today's plea for forgiveness comes from a reader Regomised as "Doug" and is a warning to careless …

    Nobody told me I wasn't allowed to do it.

    While not a defence in law, this is precisely the approach that is often needed in IT.

    The best tester I ever worked would come up to us and say, "When I do [THIS], then [THIS], then [THIS], it goes kaboom". We would ask, "Why would you even try to do that combination", to which he would reasonably answer, "Because it allowed me to". We would then either make it impossible to so do, unless it was a safe combination and should have worked in which case we would fix it.

    An unguarded prompt is the same opportunity (or temptation). What can I do with this? What could possibly go wrong?

        My father in law had a similar guy in his team. He would carefully read the design documents and then break things very quickly. Best thing was that he actually figured out the password checking program would allow him to enter eight blank spaces as a password, because apparently the " " was counted in more than one list of acceptable characters, and thus fulfilled the "get one character at least from each of these lists"-criterium. Which was a bloody stupid mistake, but every programmer has made one mistake of this kind (at least). If we are lucky it gets caught in testing...

        Ours was called Malcolm. He could break anything without trying. Eventually I had to add a series of traps in the code looking for unexpected input and branching to a subroutine with a label called [OhGodItsMalcolm] where the input was discarded before carrying on. This was our first real programming experience on a CCPM-based data processing system using Dataflex 3GL back in the mid 80's. It had 1MB of memory shared between the OS and the three user terminals.

      Yeeeeeees... This is what QA is *meant* to do. Try anything, everything, see what happens. Even if that doesn't make sense to a developer and they rant on about how QA are trying all sorts of crap instead of testing the software.

      No love, that *is* testing the software. If you do not sanitise your inputs, and you don't make sure your software doesn't let silly things like that happen, then yes, love, your software is going to do stupid things.

      QA were, as much as they were the bane of the developers, my best friends because they highlighted pathways in the software that hadn't been thought of during the design/development process that needed to be... fixed/accomodated.

      And yes. Unguarded prompts? Oh boy!

        80%+ of development is handling things going wrong, that not only includes uncontrollable things like network disconnections, running out of memory, etc. as well as sanitising any and all user input. Sanitising user input does, of course, include the fundamental precept that no user input is trusted.

        In my experience, far too many developers only think about the "golden path" through the software, where everything goes exactly as expected.

          It should be. It seems to be less and less the case. Sometimes just working out that things have gone wrong would be a start. Simple things like run a report at 5 mins past the hour to list everything that should have been in that hour's shipment but is still unshipped. It's just easier to let the customer complain.

          Thinking only in terms of happy paths is the sort of thing that you expect from new grad devs maaaaaybe, anyone with a year of experience in industry still doing it is probably unemployed if I'm honest. Or at least unemployable at anywhere I've worked.

          I recall an interesting stat, I don't remember the exact number but there was a fat metastudy a while back that showed a solid majority (well over 50%) of all outages that cost companies money could be attributed directly to missed error handling conditions. Even pretty bad engineers should be acutely aware of this.

          EDIT: Thinking about it, most places I've worked if you didn't include automated tests for the error conditions or explanation of how they were tested in the pull it would be shut down without further consideration immediately.

              That is indeed the bane of each and every company. I cannot count the times our manglement tried to "optimise" (AKA: prohibit) any kind of real testing as long as the documentations were according to ISO 9000++ (AKA: falsified). This might come out a tad unhealthy, considering that our machines handle up to 30 tons/30000 kilograms with interesting speed.

              I also cannot count the times that manglement allowed only time for a perfect path and timeframe for an also perfectly new prototype. This realitiy incompatible over optimistic approach failed each and every time, as predicted. Those predictions were naturally brushed aside in sheer arrogance, no matter how often (every time) the writing on the wall was glowing so hard that it could be seen galaxies away.

              Bonus points if this nonsense timeframe was already contractually agreed to (of course without checking on the nominal delivery time for special components, which often exceeded the agreed on delivery date of the finished product) and suddenly bears the danger of not only an angered customer but also hefty penalty fees.

              But as always.... it does not hurt where the decisions are made and the decisions leading to the issue cannot be influenced where it hurts most.

              In such occasions, i really wish for Marx... Not Harpo, Groucho or Karl but the nice little high voltage generator, contacted at the correct place where the issue of the false decision constantly happens.

          One thing that is hard to test for is device errors because they don't happen very often. Sometimes planting a branch in code to make it appear that an error has occurred might be the only way.

            Device errors

            Quite some time ago (around the turn of the century) I was doing test and diagnostics for a new product.

            Said product was in a 3U compact PCI rack with a couple of boards we had designed. My code ran on a host and connected via sockets (the joys of ioctl).

            I was just getting the new tests running prior to these boxes going to production and I was getting weird errors.

            Turns out that during the hardware initialisation (hand crafted PCI enumeration included) none of the initialisation code checked for errors. Therefore a failed init was a totally silent failure until I tried connecting to it.

            I added a status word to the init code and successively cleared bits during the init sequence; in good 'C' fashion, zero in that word post init meant everything had worked but also had the added functionality that a non zero result identified just where in the init sequence things had gone wrong, saving significant troubleshooting time at production.

            I just wish they had followed the 10 commandments for C programmers (see item 6) in the first place.

            Re: Nobody told me I wasn't allowed to do it.

            Device errors might not happen, but ensuring they are handled is better than some code I've seen (opened a file, spewed out information, closed file) and without one single check. Ironically what brought that down was the file handle being null due to unable to create the file, and then trying to write to a null handle. Oddly enough the system didn't appreciate that.

            But still...

          Case in point in the old days: giving "restricted accounts" which only let people do email.

          Do you know how many ways there were to break out of Pine (or most other "email programs") into a shell?

          I set up a reward system. Any user who could send me a message after breaking out of the mail system got $10. I thought I'd nailed it down before letting people loose on it but ended up shelling out a few hundred dollars anyway (some didn't bother with the message, but enough did that the holes were picked up quickly)

        Re: Nobody told me I wasn't allowed to do it.

        "Yeeeeeees... This is what QA is *meant* to do."

        Well, not necessarily. There is a line of reasoning that boils down to "you can't test-in quality" (or more fundamentally you can't bolt it on. Testing can detect and remove flaws - but at best a low test failure rate might indicate good quality. Quality is a result of sound planning, development and implementation using processes that aim to prevent or quickly eliminate defects and errors.

        In this line of thinking Testers test - ideally they should be good engineers familiar with the system and be well read on testing methodologies. Quality Assurance is concerned with making sure things are done in accordance with the appropriate standards and procedures, by suitably skilled people - they might even run key reviews (though not be the subject matter experts). They [should] report independently from project management and [theoretically] are free from the project delivery pressures of the project team.

        In reality quality is everybody's responsibility if you want to build a high quality product.

          You need someone who is NOT an Engineer familiar with the system. Those who are UNfamiliar test it the real way, since they don't know what is expected.

          1. SCP

            Re: Nobody told me I wasn't allowed to do it.

            Randomized (or even methodical) input testing based on zero knowledge can be automated using fuzzing techniques.

            Deeper testing of a system requires an understanding of what it is meant to be doing and an knowledge of the ways in which things can go wron. It is this element of engineering that is often overlooked by implementors and is a skill that those who excel at testing have an affinity for. Good testers should always have this different viewpoint of the system. Some of their task can be completed without an understanding of the system - but system knowledge can also be used to inform testing.

            However, all this does not build in quality, but should be _part_ of a process that assures quality (and QA should be checking that that process is being properly applied). If testing is finding more than infrequent design and implementation errors that is an indication that the execution of the design/implementation is flawed. Simply patching up those errors is unlikely to result in a good quality system.

            Re: Nobody told me I wasn't allowed to do it.

            This is a very dev-minded approach to the concept. The good testers I've met in my time understood black box and white box testing, understood the tradeoffs and came to the eng team with what they wanted to know about the system and what they didn't want to know about the system and in what order/when before a single workpiece came their way.

      You mean Testers don't do this type of thing as standard? I've beta tested several products in my time. Knowing the product inside out meant that I could think up many a devious way to try and break it by doing something "unusual".

      As a member of a student informal group that was interested in computers (mainframes at the time), during an ad hoc discussion by this group of testing I stated that terrible inputs should always be filtered. As an example of something that should never be allowed and would be filtered, I entered "remove =/=" on a teletype connected Burroughs 5500 (MCP OS which had a common one-level file system). When the teletype did not respond instantly with a message indicating prohibited input, everyone in the group looked at each other with an immediate packing up, quiet disappearance, and subsequent absence from the university computing center for several days.

      A major historical and continuing design flaw has been the development of ad hoc input parser's by software developers (for parsers or any parameter passing mechanism) which assume an OS, character set (especially escape sequences and display rendering), user cultural behaviors, and downstream/upstream validation filtering. A technique that has proven very effective is to create a LALR(1) grammar exclusively for parsing all input with the grammar establishing which character sets, characters, and character set tuples are allowed for further parsing and analysis by a language or context-specific LALR(1) grammar.

          Typed it into a REM in the first line of the program, with a call to the address of the first byte of the REM (which was one of the few fixed addresses in a program on a ZX81), and the display became a scrambled mess with no way to fix it. The only way was to power-cycle the system.

          I used this method on my own ZX81, which had an extra 1K of static memory added under the keyboard, to provide programmable character sets. It puzzled a lot of people who saw my ZX81 displaying everything in lower-case, and I had some interesting times drawing music on the screen, and playing it at the same time on a Quiksilver sound board.

      I remember at school discovering that holding down R whilst powering on did something hideous to the machine. No warning, countdown or on screen confirmation, just immediate Bork. Obviously we did on a few more machines before we convinced ourselves that it wasn't just chance that that particular machine had chosen that particular moment to destroy itself.

      It was near permanent. It took our teacher about a week to find out how to fix it, then about an hour with each machine to actually fix it. As I recall he got it down to a few minutes before finally coming down hard on us for doing it again and again and again.

      I once visited my local Fry's Electronics, browsed their demo machines, & discovered one had been left unlocked.

      I changed the DOS prompt to read "C:\> Press any key to initiate the self destruct sequence..."

      It was fun to watch customers approach, lift their hands in preparation to type something, then their eyes go wide & they backpeddled as if confronted with a ravenous Bugbladder beast of Traal.

      Even funnier were the *employees* whom theoreticly should have known better.

      Anyway, one clerk comes over, notices the prompt, & calmly rips the power cord out of the power strip along the back. He unlocks the security cable, removes that computer, puts a fresh one in it's place, locks down the new one, & turns it on.

      No funky prompt, he locks the keyboard, picks up the suspect one, & wanders off.

      Too bad I'd watched him typing in the password of "Frys". Walk up, hit the shift key to get the screen saver lock screen, enter the password, & go back to futzing with their shiny clean demo machine.

    Don't do that!

    Worked in an organisation that used smartcard and pins for authentication. I was in the office where the system admins worked. This was not a secure office. The admins regularly left their cards in the reader and buggered off. They usually had a loooong timeout set too. (saves having to put that long and complex four digit pin in.)

    Procedures dictated that unattended smartcards be removed and reported. The System Mangler wasn't happy, the paperwork was a pain, and said to stop it.

    So we (I) did stop. Didn't stop us (me) adding clear sticky tape to the chip or trimming the edges of the card so it was to small for the ID card holder. Or adding facial hair in indelible ink to the picture on the card.

    Turns out this was more effective than them getting bollockings!

        That was a great feature, until you kept forgetting to grab your card when you left the office (which I did all the time). The office manager got irate with me since she had to keep giving me a new card. Also, I'd forget about it, then I would have 3 session going on the server for weeks at a time. I finally remembered and had to go through and kill all of my old sessions off.

        Re: Don't do that!

        The SunRays were fantastic for that. I was working for Sun at the time, and they were everywhere in the vast Sun facility I was working at. Getting from one side of the facility to the other was about a 15 minute walk. As part of the job I often had to go all over the facility, and being able to just walk around with my ID card and slot it into whichever SunRay was closest meant no dragging a laptop about, and laptops weren't common at the time, most organisations used desktops. Meetings were great too, the team just slotted their ID into the SunRay in the meeting room and there were the materials they wanted to demo.

        The downside was when you forgot to pull your ID card out of the SunRay and walked away, most typically happened when you left your ID card as far away as possible from where you next needed it, usually back at my desk at one far side of the facility. Bonus points if the SunRay in question was behind an ID card secured door (we had them in the comms and server rooms), so in addition to the long walk you needed to beg a colleagues ID card (who then couldn't work on a SunRay until you got back)

    similar...

    While at university in the mid 90s, my mate and I were doing some work and needed to FTP a file to/from one of the servers, so we opened up the supplied FTP client (stored on a Novell fileshare IIRC), typed in the server name and found an auto-completed config set for that server. With the root account. And a password saved in the config. We looked at each other and hit "connect"... and promptly had an FTP session on the server as root.

    After confirming we were definitely in as root (by downloading, deleting and re-uploading /etc/passwd - yes, a bad choice in retrospect, we could have FUBAR'd the machine), we decided we'd better tell the lecturer who looked after that box about the issue. The config in the FTP client was removed that day.

      There were too many fellow students using the same box for anybody to do anything silly with the access, tempting though rm * (no need for the -r back then) may have been.

    We used to send data to a third party marketing company for them to prepare mailshots for us. This was done via FTP. One day after uploading our file, I decided to cd ../ and much to my surprise, it allowed me to. Being the curious sort, I then typed ls -la and saw a list of recognisable company names. Picking one at random, I was able to access not only their directory but also their data.

    This was in the mid-90s when "hacking" was Very Naughty. I spoke to my boss who was in the same quandary as me - report it as a security risk or potentially get arrested? His decision was to keep quiet about it.

      People used to complain that "hacking" had been distorted from its original 60s and 70s "hacker culture" definition to instead mean someone doing illegal/dubious security-related things (a la your 90s definition).

      It's ironic that even *that* meaning has been degraded and redefined in an undignified way, a la "life hacks" or (e.g.) "menu hack", the latter being where you use various techniques (e.g. asking the staff for unlisted items or combining existing ones) to create something not on the regular menu.

        My favourite: ~1998 reporting a stolen credit card (mail intercepted) at the Chelsea police station. The lone PC there was sitting there typing (hunt&pecking) the report into their expensive custom-built police system, and the phone rings. He picks up a tightly-folded battered-looking little square wodge of paper from beside the keyboard, wedges it into the gap between the spacebar and the surrounds, and goes and picks up what turned out to be a lengthy phonecall.

        As he went back to his desk I asked him what on earth the paper + spacebar thing was all about.

        Turns out the IT architects/developers never bothered talking to actual policemen, let alone watching them as they did their jobs. And "for security" they put a short timeout on every data entry screen : stop typing for a minute and you'd lose the lot.

        Well, their job is filled with unschedulable interruptions. And they'd worked out that if you jammed the spacebar it'd keep firing in keystrokes and keep the screen alive. When they could come back to it, they'd just hit Tab (and trailing whitespace was trimmed), then Shift-Tab, and go back to typing where they left off.

    Back in the days when I was a "student assistant" at Uni, one of the other SAs set up batch files for "dir", "syscon", and other common Novell commands in his home directory that would log someone out. His reasoning being that was the quickest way to get logged out if you left yourself logged in and someone else discovered it.

    So a high-level sysadmin found his account logged in, did a dir and got logged out. For some reason, she was furious... mainly because she wasn't too bright and didn't understand what just happened.

    He got a huge bollocking from the head of sysadmins for his "shenanigans", but when it escalated to the department director, he was cleared and congratulated as a clever chap.

    This didn't endear him to the sysadmins for a while, until they finally actually understood what he was doing, and grudgingly admitted it was a good idea after all.

    Telnet from a terminal?

    "We could telnet from these terminals to our box..." Eh? Terminals in those days were connected with an RS232 interface to the Unix boxes, especially those iserver room. That was plain RS232, not the emulated version over TCP/IP that telnet is.

      The terminals were probably connected to a terminal server like an Annex, which acted as a serial "switch" to allow direct serial connections where you could tell it what server you wanted to be connected to, but also supported telnet to wherever was accessible via its network connection (the entire internet, in some cases)

      As I read it Doug was on terminal at client site & telneted from there to his office.

    They never learn

    10 years after leaving a sysadmin job at a UK university I decided, on a whim, to try telnetting in to their main admin server. Imagine my surprise when I found my account was still active, the password unchanged and still with sudo access? I did the decent thing and left a message in the operators terminal window…..

    They should have been fired

    They obviously knew what root was, and were quite familiar with Unix commands since they were able to put together a shutdown command. They either didn't bother to check what server it was or did but lied about not knowing. I'm guessing they were planning to "teach a lesson" to whoever left it logged in as root, but teaching a lesson would be leaving 'echo "you shouldn't leave a root shell logged in"' not leaving a shutdown trap that they know would impact their client's business.

    I usually have sympathy for the "Who Me" subject, but not this week. That's a high school level prank, not something a professional should be doing. If they had worked for me, they would be removed from that client site instantly. If they were REALLY good at their jobs I'd consider keeping them around after making it very clear to them that they will be left without a job and without references should anything remotely like that ever happen again. If they were just average I'd figure they were easily replaceable and would do just that.

    Been there ..

    "never, ever, leave superuser accounts logged in."

    Many times. I walk up to use a terminal and it's logged on as root.

    Look around. "Hello. Is anyone using this? Anyone? Hello?"

    I just type in 'exit' and 'whoami' one more time to find the actual user name of the moron who left the system vulnerable. Log them off and go about my business.

    Reminds me of a time way back when a colleague was trying to kill a rogue process, traced it back to its root and cheerfully did "kill -9 1".

    Almost immediately the penny dropped, and was rapidly followed by a facepalm heard all the way across the office.

    Fortunately the system was back up five minutes later and as it was already running slowly we just told everyone it was overloaded and had crashed and nobody seemed to think that was out of the question.

      "a colleague was trying to kill a rogue process, traced it back to its root and cheerfully did "kill -9 1"."

      And then he convinced the Boss that it was all the systemd-cancer's fault, and was promptly given permission to replace the clusterfuck with a real init?

    Back in day with Unix NFS auto-mount

    If you had root password on Unix ..

    You could mount anyone's NFS home directory on a test lab machine and read their ~/mail that was in text

    So I was told

    Many people have told me that

    I never said this

      Re: Back in day with Unix NFS auto-mount

      When you have root access, it means you have ... root access. And you can do all the things that root can do, including reading users' files. If you are supposed to have access to run some commands as root but not to read others' files, then the admins should not give you full root access.

    all you needed was win95 and solaris

    we had big filers running solaris and samba

    grab a windows 95 computer , hit escape to bypass login screen. make new user on the windows box named 'root' with blank password

    Connect to filer by mapping network drive.

    Drag and drop folders around. copy a bunch of pictures from windows to the filer.

    all that stuff was done by 'root'.

    The cause was a bug in solaris whereby it did not re authenticate. it said you are root over there, so you are root over here...

    The two extremese of testing

    One of our testers said there are two extremes in testing

    1) No matter what we did - we could not break it

    2) If we were careful, and the wind was behind us, and we didnt push it - we could get all of our tests to run.

    His favourite scenario was to limit the virtual storage allocated to each components and then hammer it. Including doing things in "the wrong order" and restarting it half way through. All that was "easy". The hard part was making it repeatable so that the same scenario could be retested with any fixes.

      Re: The two extremese of testing

      To this day there are so many apps in that limbo -- heavily multithreaded to take advantage of all the horsepower in modern CPUs, but one out of every 40 CI runs inexplicably fails, and if you want to paper over the race condition you can just run another and it'll work again.

      Until the bug reports roll in.

      Re: The two extremese of testing

      At a previous job, I built some SMTP relays. They were highly tuned Linux servers with lots of disk space for mail spools. I published benchmarks, something like 1 million messages per day per server.

      Years later, another team took over responsibility for email. Their tech lead made a Great Project to replace this old low-budget infrastructure with world-class appliances. He got test gear and quotes from 3 vendors, any of which utterly eclipsed the performance (and cost) of the Linux relays. Someone got me invited to help test.

      My first suggestion was to list all the failure modes that each device was protected against: failed drives (RAID), redundant power supplies, battery-backed write cache, etc. Then induce every failure mode in rapid sequence. Yank a drive, wait a few minutes, re-insert it, wait until it started to rebuild the array. Then pull power from one supply, reconnect, yank the other power cord, reconnect, then pull both. Power it back on then start the performance test.

      One appliance failed immediately. The others were badly impaired. Vendors got upset, and the tech lead was livid because he didn't look good either.

      At a Meeting with managers and vendors, Tech Lead called me out on this BS. I was only sabotaging the project out of jealousy. He observed that the old relays had never been through that.

      I showed them my original test results, where I had done exactly the same tests, but had first queued up 7 days of email on the Linux relays "because it could happen."

      One appliance really shone. We bought that one. He never invited me to another project.

    Unguarded terminals...

    Back in the days of VMS, a favorite activiy on finding an unguarded terminal was to modify the login script to alias 'dir' to 'dir/exclude=*.*', and then logging out...

    The cries of agony from unsuspecting users complaining all their files had been deleted :-)

    Working for a national company in headquarters, with around 20 IT staff in an open plan office, the rule was if you walked away from your computer without locking it, then it was fair game. One of our staff made a point of setting the desktop to be pictures of kittens and leaving an email to management telling them that you quit.

    I never needed to hack our shiny new £50,000 UNIX Server, it was left completely open.

    Full rwx permissions and privileges. Just change directory to another user

    I was angry at our 3rd party supplier's incompetence but never said anything

    It was too useful knowing the salary of everyone in the company

    And the secret plans to geographically relocate to a cheaper part of the country, 150 miles away

    Four of us, in the know, went to the Managing Director and complained and the plan was kiboshed.

    (most of our customers were in the South East)

    We set up a meeting at his house one evening

    "How do you know all this?"

    "Can't say, sorry"

    The loophole was never closed

    Nothing much but treated like naughty schoolboys in front of the headmaster.

    Left alone in the testing and development lab of our parent company in Germany we had access to terminals.

    Played with commands to no real effect, luckily, I guess.

    We found a command/script "crumple" which had the pleasing effect of, well, crumpeling the screen.

    Nothing bad.

    Next day we mentioned it, we were interrogated and finally called into the big bosses office

    It started with "wtf were you thinking of" you could have caused untold damage and cost time and money and so on. (They were all valid points, we had no Unix knowledge and...)

    We left feeling totally told off as if we were still at school.

    Mind you, Munich and a few beers later, wft, Prost!

    A student who was a Student's Union officer left herself logged in.

    Another student decided to post under her login "I'm a stupid expletive expletive. I've let myself logged in" and an invite to tell her that via her email.

    This was posted to alt.test, misc.politics, alt.flame, alt.tasteless and a few other delectable groups.

    The sysadmins had a hell of a time with her account mailbox being over quota within minutes of this happening.

    "Curtis broke it"

    I am routinely put on beta teams at my employer with the instructions "Hey, Curtis. See if you can break this". And I do. Because the guys doing the programming don't actually use the software daily.

    To this day, there's one dev who has stated that under no circumstances am I allowed to "test" his software. Interestingly, whenever he says that, upper management then pulls him off whatever project he's working on.

    Not devious enough.

    Whoever woke it up with enter got to see the command before the machine shut off...

    A really devious person would do something more like:

    echo "alias vi='grep -v bOzO .bashrc > brc ; mv brc .bashrc ; shutdown -h -Q 30' " >> .bashrc

    That way they don't get to see the shutdown command when they wake it up with the enter key. Could lurk for days...
