NOTE: The bellow is only the option of it's poster, Dan. Like all posts on CompSci.ca, it is only option and only the option of the poster. NOTE: 'LanSchooled' is not the same as LanSchool, nor does it provied the same functions of or even work now that the potential security flaw has been fixed in LanSchool. For more up to date infromation see the wiki: and Normaly i whould not think of posting such work on this site but this is part of my campain to get school borads to realise that they shoud not be using LanSchool and that there are masive security falws in it. The Story During grade 12 i chaged schools, the new school i whent to had alot better networks and computer labs witch was a good thing, or so i thought.
Free LanSchool Download, LanSchool 7.6.2.8. Teachers today are faced with the challenge and opportunity of using technology to teach. Computers are amazing.
After playing around for a bit i noticed a litte green icon in the tast bar that did not seem to do anyting. Looking feathure in to this i found out it was a progame named LanSchool (Now what is LanSchool you mayask, the names makes it sound insent enought, maybe somthing to help students? Elastik Sound Bank Crack. Well it may have started out that way but what it has become is basiclky a toringhorse progame for teachers to use to watch everything you are doing (incduing watching your screen) as well as giving them the ablity to control your computer or all computers in the lab at the same time.
As ushealy the school borad decsied to spend money on somthing they could get for free and got a crapyer verson then what they could get for free. So i started looking in to LanSchool more and found a demo verson on there site. This demo verson could not interact with real versons the school used and whould not allow studens to do any damge.
1st i looked in to how it was effecting the regiersy of the computers it was on, and found that every time the teacher application sent a comand to the student versons it recored what windows user sent the comand, the windows name of the computer they where on and the time in all regersitrys of every comp on the network. This ment that finding a full verson of the software althougth not hard whould end you up in alot of trouble unless you brought your own computer to school and even then still could. So i begain to look at the packets it was send and to my shock they where UDP and not TCP and they had no ecription or coding at all to them. This means that it is exteramly easy to spoof the packets.
So i quiclky wrote up a simple java progame to test out my theroy. Affter some time and exmermentation i decoded what most of the packets ment and was able to control the demo verson of LanSchool.
Affter looking more at the packets i noticed that the difrces between the demo verson and the real verson is that the demo verso uses only one chanale witchis never used by the real verson. So it was simple a madder of chaing the chanel byte to a real chanle in the packet to get it to work with most if not all versons of LanSchool. Also this allowed me to make the regeisty logs say what ever i whonted, incuding blaming other stutdents for the hack. Now being the nice guy that i am i e-maied my findings to LanSchool and sugested several ways to fix this expolite. There repsoses was basiclky saying that they whould rather send time and effort enforcing the rules of the school and the law then fixing there progame.
And made threats that legal aucation as well as sudesnions could take place if i where to use this progame. So next i whent to my school and aucatly demstorated (with there permision) the expoite and how unscure it was. Again nothing happend with my efforts so amoth latter i published how the packet worked on compsci.ca.
It is now almost 2 years latter and i have rewriten my hack so any one even script kiddys can use it. With a nice gui and everything. My hope by doing this is to teach peoleop why progaming like LanSchool did is bad security wise and to encorge the school borad to buy (if they most) better software from comapnys that know what they are doing and are willing to chage with the times.
BTW LanSchools website still claims that there are no know bugs with LanSchool. Computer Science Canada Help with programming in C, C++, Java, PHP, Ruby, Turing, VB and more!

To bad I cant go back and try this out. So thats why they call you HACKER Dan.

Teachers often 'take control' of your computer, and even more often view what you are doing.

Uhsely it is only the network admin that dose. Still i whould sugested reporting this to your school and or school borad to help the cause in geting ride/fixing it.

Most teachers I have seen know how to use it, and the software used isn't lanschool either so the same exploit probably wouldn't work. Chrispminis Posted: Sat Feb 25, 2006 3:28 pm Post subject: (No subject) Such harsh replies from LanSchool, would it be too much of a hassle to post your letter to them, and their reply?
I wanna read it word for word. Dan Posted: Sat Feb 25, 2006 4:00 pm Post subject: (No subject).
Such harsh replies from LanSchool, would it be too much of a hassle to post your letter to them, and their reply? I wanna read it word for word. I whould love to but this was over 2 years ago when i made the 1st verson and talked to lanschool. I dougth i still have a copy since i moved like 3 times inbetween then and now but if i find a copy i will send you one.
If some one can confourm that this hack works on a full verson (threw legal means) i will talk to them again and make post what they say.

Rizzix Posted: Sat Feb 25, 2006 10:29 pm Post subject: (No subject) Dan it is illegal to post such exploits. You have to first let the company 'fix' them only then can you publish them. On the other hand you could always widespread the exploits through some annonymous network.
This would force the company to 'fix' them. And there's no way to blame it on you.

I do not blive that is ture in canada and rember this for education reasons jamonathin: when u hover over the green icon it will tell you what channel it is running on you need this to set the right channel or just set send to all. As for the verson try 0, 1, 2 and 9.

Actually Dan, rizzix I believe is correct, but it's not really illegal so much as the company could sue you and probably win over it. Aucatly form the law i have read incuding on the RMP web site it says that you have to have unahuthized access to a computer system to be viloting the law. If i where to use this expoit on some one eltes computer system/network i whould be breaking the law. But just making the expoit for educational reasons is not aggsited the law in canada but it is agaited the law in the u.s.a. How ever there is a big difrence between breaking the law and geting sued.
You can do somthing legal and get sued. Tho i find this to be rather unlikey in this case.
Also it should be noted that in canadain hacking cases all hackers who got caugth and where not aucatly derstoying anything or stealing money where senteced to a maxume of 12 moth probation and 2 months of comunity serivce. Tho it should also be noted that the u.s. Has impresed hackers with out trials under nataional security reasons and could basikly never let them out or contacnt any one ever again and never see a layer. Edit: In addtion to the above it whould be exteramly bad for lanschool to pursue legal or clive law sutis agsited me since the P.R. Whould be horriable. This comapny almost sloely relies on schools for it's income. Title like 'LanSchool sues stutden who trys to help' and 'LanSchool expoited by studens and dose nothing' are not going to big selling points for them.

US is screwed up, but Canada does give you a criminal record. I'm clean so far hehe, i'd rather stay that way. Very ture but i am 99.5% shure that writing software alone will not get u one. You have to use it to gain unautherised access.
And that is only in some provinces others simpley do not have any law about it. The way candian hacking law works for the most part is that u have to break another nonhacking spefick law. For example if u hack in to a bank and steal moeny you get charged with stealing money. If you destory files u get chaged with tings ranging form vandlismes to mistuchife. Just hacking in to a system could get u the comunity sevirece metioned above but wrting an expoit to do it and not using it will not.
It falls under free speah and such. If you wiret up plans to steal money and get away with it and post them online u will not go to jail, how ever if u go threw with thos plans u do go to jail. I blive it to be the same with software explites and if i do get craged with somthing it whould be one hell of a law cases since i could applie to free speeah and bring it up prity high. By the time it was out of the courts i whould be retring and lanschool whould be long since dead. Computer Science Canada Help with programming in C, C++, Java, PHP, Ruby, Turing, VB and more! Md Posted: Sun Feb 26, 2006 1:57 am Post subject: (No subject) It's an old one but you can be charged with theft of computer time. Of course these days computer time is rather cheap.
In reality hacking is not illegal in Canada; nor is posting exploits of comercial software. You don't need to give them any notice first either; even in the states. There are big cries in the media about it from companies like Microsoft, but IIRC no one has ever been successfully sued.

Recommended Subreddits: • • • • • • • • •. At my school they used lanschool software on all of the computers to monitor students. I didn't like it so I found a torrent with the teacher version on the pirate bay and uninstalled the student one. My original intent was only to uninstall the service, but my friends slowly convinced me to mess with other people in our 'computers class'. While experimenting with the GUI for Lanschool, I accidentally started to remotely control everyone's computers.
My instincts told me to immediately shutdown everyone and unplug my computer. I wouldn't have been caught if my friend next to me hadn't burst out laughing. Afterwards whilst being interviewed by our school's incredibly stupid IT guy, he noticed that there was a file in the public directory of our school's network named 'Flash Gordon'. Inside were three encrypted.7z (i mean that there were compressed archives full of my encrypted files) files which could only be de-crypted by software on my USB. (I don't remember what it was, I haven't used Windows since I installed Ubuntu 2 years ago) He accused me of hiding some sort of hacking modding scripts inside those files (which was true).
He wasn't very bright though and he couldn't actually de-crypt them, he just assumed his title of Chief Computer Technician would override whatever defense I used in front of this principle's assistant guy who would determine what my punishment was. The next day before the assistant I defended my case using big words I wrote down and had rehearsed beforehand to insure no one could possibly comprehend what I was saying. My parents testified for me and I was able to convince the assistant that the encrypted files were save-games for a dungeon crawler.
I was still given three days of detention, but in my mind it was totally worth making a fool of the IT asshole at my old school. TLDR: I get in trouble for hijacking Lanschool but end up getting the opportunity to make the IT guy look like a dumb-ass. When I was in grade 8, my school had lanschool installed on the computers, and the teachers constantly watched any of the 'bad' kids.
My remedy since grade 6 was always to just kill the process, then in grade seven there was an update that kept restarting the process every time I killed it. So I wrote a batch script to continuously kill the process in an infinite loop.
Mid-term, there was an update that stopped users from killing the process. So I kept trying to think of a way to get around lanschool. At the end of grade 7 I figured out how to replace the sticky keys file with a command prompt, and I elevated myself to system level and was able to kill the process.
In grade 8 I realized I could run lanschool as a teacher from any admin or higher account. My first mistake was when I misunderstood the 'Show Student' button, I thought I would show me my buddies' screen, but instead it showed his screen to the rest of the class. The rest of grade 8 I kept messing around with the GUI and fucking with some of my friends. One time I would keep drawing dicks on my friends' screen with the pen tool every day, and he would get super pissed about it and one time he said 'WHY DOES THIS KEEP HAPPENING!' And everyone was laughing. Teachers found out it was me after I while when I got careless, and I was banned from the computers for a month or something. The rep as 'The Hacker Kid' made it all worth it.
