Be Safe From short url's

You must have come across urls like http://goo.gl/XoG1z .They surely make it easier to share and remember long urls but are prone to be used by hackers.Since you so not know what site you are being redirected to beforehand this exploit can easily be used for phishing and other illegitimate uses.
In order to know beforehand the url you are opening it's better to check out to what url you are being redirected.
For url shortened by google(like the one shown before) you  can add a '+' symbol to get the info.For example to get info about http://goo.gl/XoG1z just go to http://goo.gl/XoG1z+
For all other url short urls you can visit longurl.org they decode for a number of services.You can also get their firefox addon(it works for firefox4 and firefox 5.it also works for ff6 but somehow it shows incompatible) and Chrome extension.

Lock Folders in windows xp and windows 7

Hi all, to lock folders is sometimes a necessity.The process is quite simple


LOCKING
first of all put all the files you want to lock in a folder,let's say "lock".Now rename the folder to
"lock.{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0}" for windows7
"lock.{FEF10DED-355E-4e06-9381-9B24D7F7CC88}"for windows xp
but the folder will still appear to be named as "lock" with added security such as nothing will happen when you try to open it.

Hack Facebook Groups

First things first---not all groups can be hacked.Only groups having an email id can be hacked,typically groups having email id will show their email id on their page (as shown in highlighted part of  image) .

You must also know art of fake mailing(Learn here!).
The last thing you need to know is the email address of victim registered with facebook.

Facebook groups have a feature that by enabling email address for group,it's users can post in group using an email.The problem with this feature is that it does nothing to verify identity of user except his/her email address which can easily be faked.
To post in group, simply mail the group such that the mail received by group id  looks like:
From:   victim@example.com
To:        hacked@groups.facebook.com
Sub:      wall
Body:    Here insert the text you want to post from your victim's email address


The post will appear almost instantly.


Enjoy!!!
