Hi guys ... I have serious problem with my brother who keep hacking into my Windows XP eventhough I got put password. I'm not sure how he managed to bypass my password and play games with it. I need help !!! Any software to prevent this ? Please enlighten me LYN members ....

why u scared ur bro hack ur pc??
got porn??
maybe u can use google and search..

eh.. not so easy to hack wan worr... unless he has a key logger check that out man...

Set the administrator password

I set liao ... i duno how he bypass it ... It's windows password ... not the BIOS startup password ...

It's so easy to hack even if it's BIOS or windows password..

Windows password can be bypassed using a linux to change the password =) Or if you didn't set administrator password then it can be login easily. Although it's not displayed in the user list. (Usually can see in safe mode)

Go find a software that locks your pc. Then make that software start everytime? =/ Not good enough also.. You still need a 3rd party software somehow.

congrats. u got a clever bro.

Disable boot on USB / boot on CD.

Put password for administrator.

Done.

The above works well if your bro don't know what you did.

any recommendations for 3rd part software ? These days i go original IT products ...

maybe try the USB pw thingy? like plug in yr thumbdrive to unlock the computer?

i think u put some thing easy to rmb, eg: IC number, phone number or such
put something like vi84cd79

100% cant crack de

really easy to crack ka..use software or what??..

go into ur bios,
1) in the boot sequence, select HDD as ur 1st boot up
2) set a bios password for changing ur bios setting (not password for bios boot up).

go into ur windows
1) change ur admin user name to other name and change the password
2) create a new user as normal user with the previous admin user name and password

so whenever he login to the previous admin name, it will be act as normal user, or mayb u wan to set it as guest, its up to u

There is a certain software to hack Windows Administrator Password, You just insert it to your USB, & boot from it.

You have one smart bro
How old is he?

Ya disable he boot from usb can prevent he to use USB to hack the window password

ai ya just use linux boot up cd oledi can bypass administrator password or even admin rite.

then u ned winzip your files with paassword or install folder guard software to protect your sensitive files.

yes another solution to too. is your dvd-rom can be unplugged 1 ?

Haha ... problem solved. Everyday change password .. tedious but it's working. hehe ... my bro is 18 this year. Me older abit.

Why cannot share computer with him ??

Just set bios password.
He cannot boot from the drive then

BIOS password? Gah! Open the casing and reset BIOS, puh the password gone. XP password? Use Ophcrack, in less than 10 minute the password is in hand already.

Create a hard, cryptic password, more than 14 characters, add spaces and symbols. Change it every week.

Open The Hardisk ,
Bring it to anywhere.

Or open the ram ,
Bring it anywhere.

Because all the password is crackable ...
Just the time it take..

Yeah.. Indeed.
I think better set long2 password+symbols etc.
If i'm not mistaken lopthcrack cannot crack long2 password.
Correct if i'm wrong because i tried it myself on my pc.

windows xp password are useless.. use 3rd party software .. remove the whole password also can

What do you mean and how?

Here But u need to search for the ahem version..

I still have to thank you on guiding me how to use OphCrack that time

where i cn geet tat ahem..hehe..

I'm really learnig alot from this. Thanks to those who contribute. I don't want to share with my brother beczo he everyday play game, and another younger brother PMR coming ....

Use Random Password Generator and change it everyday Link

This way is much secure

Err no need whatever crap software lah.

Just unplug your CDROM / DVDROM power cable from your casing (when you don't use it)

Disable boot via USB in your BIOS.

Change password every 1~2 weeks which consists of 14 alphanumerical + special symbols like !@#$%^&*()_+|"?><

That will make your computer secure from being accessed.

Then, the DVD rom will loose a bit if do that many times.

hmm....the same thing also happen in my family, i used the admin user and change the name, then create a new user with the same name as the previous admin. He was totally shock how i crack his pass, but it was too late. Now he always detach the power supply cable and hid it somewhere (dont have spare and not going into so much trouble just to use my lil bro pc)

yea, cut the power supply is the best
simple and easy.
or add bios password.

wow... extreme measures hah...
gave me an idea oso to keep my lil bro from playing games all the time n not studyin... he got pmr comin...

I used 2 USB

1) 64 MB
2) 256 MB

task is to scan pdfs that are zipped

64 MG USB took abou 1 minute
256 MB USB took about 13 sec
HDD took about 10 secs

Under load
HDD 13 secs
256 USB 19 secs

so in the end... even if the HDD is under heave load
it still beats the USB

my method is crude, but should be sufficient to prove a point
however, I dont have access to more "modern" USB devices
maybe those will yield better results

maybe your brother have a secret linux livecd to hack your account

obviously he used administrator to login to ur comp la... set admin pass, change pass regularly...

what obviously? the only obvious thing I see here is you know nothing. There's tools that can completely remove all Windows passwords, including Administrator password. The solution? Install Universal Shield, the next best thing to sex when protecting your files. It installs as a service so no one can disable it. If anyone try to uninstall, it will ask for password, if wrong password given, it will fake the uninstallation process. You can choose to hide the whole drive (just make sure you didn't hide your drive that have Windows files in it), a folder or just a single file, your wish. Then your brother will be fcuked up and he'll give up someday because he won't be able to crack it unless he can bring teh hard disk to another PC and play the game there...

I did try with XP installed with my VM. It was easy enough to go to safe mode and disable the service so that you can log on as build-in local admin account.

It was a little tricky for those protected files. I could actually see those files once in safe mode so I figured something has to be loaded in normal startup. And then I come across this one:

http://forum.lowyat.net/topic/745431#

lol?

So simple solution.

The only protection that cannot be undone or take a seriously long time to undo is probably encryption based protection. I'm pretty sure you cannot encrypt the whole HD itself without affecting the booting of XP. In any case, you can override the local admin password (in fact, any users password, and if you're smart enough, you can even change it back so that they don't know you did it) using a LiveCD. Anyhow, he'll be able to boot into the system. So in other words, the solution you provided is not as godly as you think.

Know nothing huh? zzz

BIOS password protection can be reset easily and those USB holes are everywhere on modern PC nowadays.

ooooo really? if you go here, the 18th feature in the list, developer Everstrike said that:



I've tried it myself and it's true that Safe Mode defeat the protection! I've sent Everstrike an email and let see what they'll respond to this. About encrypting, that's gonna be one hell of a job. Encrypting would take times, especially when the data to encrypt are large in size, and decrypting back... I'm too lazy to do that back and forth everytime I don't want anyone to mess with my game...

100% sure he crack with cmd through safe mode. Set a bios password, that one very secure unless your bro go and reset the whole bios.

to prevent him reset bios via bios jumper... go n lock ur casing hehehe

cool. everyday change password. sooner you yourself can't remember which f -u -c k password for the damn account.you can do what you want to do, but i still can get into your xp pc bypass the stupid password.

his brother? o.0

use my mother's method.. keep away modem..

wat if it's not online game? then keep away monitor.. my mum lock it in her wardrobe, + lock room door..

wat if monitor is CRT type? keep away power cable/monitor cable..

easier way? keep keyboard n mouse.. GG.. cant do anything without both..

y do all the hard work?? cz my mum dunno set password.. =.="

all this method are used on my bro not me cz i got my own laptop.. lol..

Your mother actually hid the monitor inside her wardrobe? That’s somewhat massive!

lcd la bro..

This is the reply I got when asking about the "protection" in safe-mode:



so looks like our friend here use "ahem" or trial version, no wonder it won't work...

Did you set auto-login in your browser? Then your bro is probably reading all your threads, hahaha
