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.

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

Added on August 8, 2008, 3:18 pmFor OP, you won't be able to stop him from boot-up and log-on to your PC if he really want to because he don't even need a CD-ROM drive to do so.

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..

14 character password can crack meh? how many hours?
even got rainbow table cannot break it easy.. my 2 cent la..

better update ur AV and block any potential dangerous prog..

no need to crack with rainbow, just use "tools" to reset the password...

Added on August 11, 2008, 4:17 pmThis 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...

This post has been edited by FarCry3r: Aug 11 2008, 04:17 PM

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

aiya.... if how many password u put also can hack 1 la. =X but duno when only mar =P the masaleh so geng 1=D

OIC.. If reset the password sure nvm la.. I mean by decrypt the key hash not easy..

If want to avoid somebody reset the admin key just purchase 3rd party sofware to block the CD-Rom, Usb and floppy..

try come out p/w with weird weird character

Why don't u ever think that put the pc in one room(if u wan ,make it very safe room)
Then, lock the door,windows with whatever locks u got.May b use high tech lock,,,,,

dont bother how ur brother hack ur password..
try find a way to make ur data inside secure..
lock ur hdd..haha,use bitlocker ka..what ever software la..

bro.. if reset the password the weird charact is useless..

yeah, whatever password even the weirdest one will gone in less than a minute... or if you fast enough, less then 15 seconds, LOL

what the hack.... also want to congrats your bro!

lol there's no way to prevent ur bro hacking ur password..
hacking pasword is as easy as 1, 2, 3....

That is becoz thanks to the microsoft, the password is stored in SAM file in the pc and the encryption is standard...
Its so easy for reverse engineering.

If u want to keep ur stuffs from him, get an external hdd

duno why so big deal, why dun u just wrack ur brother up if he using again?i very he wont even dare to touch it again

that's true, connect the external hdd, install your games, apps etc on the external hdd and connect only when you want to play or use them, if not just disconnect... or get other OS...

1. set bios password
2.set the boot priority



i think your bro go to safe mode ...if no wrong =)

I would suggest you to install a hidden camera and see how he does it. Guessing for thousand years here, won't be any use!! He might not be as clever as everyone here claims to be. Just try to peek on how he does it then you can come out with the solution lol.. Just my notion anyway..

By the way, don't ever use those method mentioned;

1)Set Admin password
2)Change Admin password day by day
3)bla bla..

It's useless as it can be reset or "break". YES, even Admin password.. within seconds.. The so call ahem software can be save in diskette, thumb drive, CD or even it's in your "C" drive already~!!

Good Luck!

How about locking your room up or put your CPU inside a small cupboard & lock it went not in used?

huhu, so trouble~

took d hdd out all thing settle

Your method is lagi susah every time need to plug in out & his brother can buy a new HD & plug in.

Last time my older brother also play my PS2 without my concern & first i took way the controller & memory card he go buy a new one, later lock the whole Ps2 inside cupboard.

Easy.. put ur pc in a cage and lock it when not in use. Solved!

In modern age, we introduce something call security key to lock and unlock the data.

Here is how the security key works....

(1) Bring out your HDD and maybe RAM also and put into a drawer
(2) Lock it with something call physical key. You can buy the locks or key in any hardware shop.
(3) Bring out your physical key when you are not around
(4) Make sure duplication of physical key in not in your house.

And when you need to access it;

(1) unlock the drawer using your key
(2) connect back your HDD and RAM

Simple, right?

It is why in modern ages, you always read about security keys....

And such security keys are more reliable than a password for XP

If you want further security, there are so call double protection; bring out the RAM when you are not around

Most of the discussions here are how weak the Windows password protection is...

IMHO, BIOS password is most secure but it need to pair with small padlock to lock the casing cover.

Usually the pc casing came with small hook to allow you to put padlock on.
Its purpose is to disallow people from resetting the BIOS and BIOS password.

p/s Seriously if you brother still able guess (or hack) the BIOS password, well congratulation to you, your brother is genius, an unstoppable nature born hacker !!!

lol lucky i dont have this kind brother


for me....take out the hdd while u finish using xD....or just use external HDD as your OS hdd ...hahahaha

CmosPwd can reset the bios pssword.. Dun forgot jumper also can reset the bios password..
Computer is upgradeable so no reason somebody cant hack it thought anyway..

To TS, u have many many2 opinion here.. gud luck lor...

get an external hdd.....

share la..

you can try truecrypt or anything equivalent...encrypts whole systems and asks for a password before booting into windows. www.truecrypt.org

sigh......this happen to my family also.......

i might try to get Vantec-300ST for prevention......

sure there available tool in internet for us to hack microsoft password, else they won't have so much encryption tool sell to control window login. since he is your ro, why not create another OS partition for him to use? So he won't touch your stuff and affected your file, imagine a year got 365days, you want set 365 password per year? then better pray for your parent cepat cepat kena 4d then buy 1 more PC to him ad you will free.

consumer level password protection is sorta a joke.... with the right tools, only need minutes to break.. but good enough to deter 'common' people...

ur bro isn't one of them..

if he discovered the method himself, means whatever u do also he'll most certainly b able to bypass....

if a friend pass to him one then he shouldn't b that smart in d first place...

just take all the the IDE/SATA cables, power cables, VGA/DVI cables , and mouse, along with u when ur not using...
should b a major fuss for him to use ur com XD

ya...taking out the parts is the most secure method...cause last time my friend try to access school's computer, he just go into safe mode then open dos and do something to reset the admin password...really simple thing for windows XP, but for vista really dunno...lolz...

reading ur prob, ive gotta say ur brother must be very annoying..

if i were you, i'd have smacked her head kow2 coz using my pc withour proper permission..

i remember back in the days when the pc had a key to unlock it.
old 486s had them.

maybe you should custom make one.
(if i knew how trust me i would)

my housemate was like ure brother.always trying his luck at the winxp password.just make the password harder to guess.
use numbers and small/big caps.

A bit OT, but honestly speaking, even if your bro has no access to the PC, it won't make him study more. You can't force people who don't want to study to study. They'll just find something else to do.

So you got to figure out the root cause and deal with it.

KEKEKE whenever u are out of ur house, just unplug the HDD and bring it with u... LOL
jk!

so many ways looo..
i'm using folder lock and pc security.
if my brother wanna play game.just lock the drive that games installed on that..
no problem anymore..
also u can lock ur folder or something else..

How hard the windows login password combination is, it just take about 5 mins to crack. So d other way u might secure ur pc is like wut Moja_view suggested.

so far this are the most acceptable solution

Really a good Trick thx for sharing anyway.. im gonna set a password @ administrator

simpler, take your power cables with you

set admin password
n set user bios password...
or the stupud solutin...
bring ide/sata cable....
very easy

change to MAC OS X

Or, can take whole HDD with yourself.

ehemm..this is one more solution..
take out ur RAM n hide it..so anyone including u cannot open that PC...

all solution above a relevant....
but did u all think that litter bit cruel when u
bring a hardware with u?
the most kind solution is bring psu cable...
haha.. easy..
or take fuse from psu cable...

Actually no matter what also can crack de.
XP Pass - Just log into safe mode then can screw up the password liaw
Bios Pass - Just use eraser to rub the chip on the motherboard

Try using Acronis Partition magic if i am not mistaken. So when you boot, must go through the acronis page. Its like XP also the password interface. But you will have to go through this page before going into the XP pass page. Its sort of like a dual protection thing.

Worse come to worse, remove the hard disk and put it back only when u wanna use it. HAHA!!!!

my suggestions is...
u donlot dis sofware..

ERD COMMANDER 2003..
then try to hack ur brother pc then change his pasword...
u can see whether he still capable to bypass that new password on his pc..

just try it...

u're too predictable, tahts why he hacked in, try to put something unexpected like..

err
eg: ilovesex
: (some blue sites)(password not promoting)
