List of digital forensics tools

During the 1980s, most of digital forensic investigations consisted of "live analysis", examining digital media directly using non-specialist tools. In the 1990s several freeware and other proprietary tools (both hardware and software) were created to allow investigations to take place without modifying media. This first set of tools mainly focused on computer forensics, although in recent years similar tools have evolved for the field of mobile device forensics.

NTLDR is Missing

If your computer suddenly stop working with a message shown in following image and you can’t start Windows, then maybe the file ntldr or ntdetect.com is corrupted or deleted.These files are always located in C:\ . Note that they are hidden system files so if you want to see them, just read this.

Now just follow the steps below.
1. Insert the Windows XP bootable CD into the computer.
2. When prompted to press any key to boot from the CD, press any key.

3. Now that you are in the Windows XP setup menu press the “R” key to repair Windows.

4. Log into your Windows installation by pressing the “1″ key and then Enter.

5. You will then be prompted for your administrator password, enter that password or if you dont have an active password just press Enter.

6. Copy the files ntldr and ntdetect.com to the C:\ ( root directory of the primary hard disk ) . In this example we are copying these files from the CD-ROM drive, which in this case has drive letter “F”. Note that this letter may be different on your computer. For example : if your hard drive has 3 partitions (e.g. C , D , E ) then most likely your CD drive will be F. Just keep in mind that the drives are arranged in alphabetical order.

7. Perform the following commands: copy F:\i386\ntldr C:\
copy F:\i386\ntdetect.com C:\

8. Once both of these files have been successfully copied, remove the CD from the computer and reboot.

Rainmeter skins provide you with useful information at a glance. It's easy to keep an eye on your system resources, like memory and battery power, or your online data streams, including email, RSS feeds, and weather forecasts. Many skins are even functional: they can record your notes and to-do lists, launch your favorite applications, and send your tweets to Twitter - all in a clean, unobtrusive interface that you can rearrange and customize to your liking.

With Rainmeter, there are no secrets. Our bundled library of open-source skins covers a wide range of functions, but if you want your desktop to do something new, you don't have to wait for us.

Every inch of a skin is completely customizable. Rainmeter skins are written in a simple, elegant language that's easy to learn for anyone who's willing to put in the effort. Skins call upon measures, a set of powerful built-in modules that do all the heavy lifting, and create interactive meters to display that information however you decide. In this way, Rainmeter brings productive innovation together with creative artistry like no other platform of its kind.

Facebook: Check your FB setting for the People, Pages, Places Directory

The Facebook People, Pages, Places directory feature (LINK) https://www.facebook.com/directory/people/ has been out now a couple of weeks, however I still find people that don’t know about it. If you were concerned about (hoping for) privacy, well this feature just pretty much ends any and all hope. With the PPP directory Facebook has every user, page, place easily accessible to everyone.

All you need to know is a name (or you can just throw in a fake name if you want to meet strangers). The screen shot below is the current 1st page of the directory..!!

Every user on Facebook is in this directory, and unfortunately (AGAIN!) Facebook does NOT give a way to completely opt out of being listed. However, there is something you can do to limit your visibility in the Facebook PPP directory.

There is now a setting (which seems to be set to Everyone by default) by going to your privacy settings (Top right of page) –> How You Connect (Bottom of page)

Once you are in the “How You Connect” window, you will see as the very 1st choice “Who can look up your timeline by name or contact info?”

Any Facebook user who is still trying to hold out for just that little bit of privacy while still being able to use Facebook will want to change the setting to Friends only, or Friends of Friends if you are ok with privacy middle ground.

Making this change should limit your exposure from the PPP directory. As always its suggested that you look over all the settings under privacy (even make notes if you have a hard time remembering) on a regular basis, you never know when a setting could be changed or added “for your benefit” that you would rather not have.

Guide to IMEI Numbers and Preserving Them on Android

Your IMEI (International Mobile Equipment Identity) is transmitted to the Network provider the moment you switch ON your phone

It is used by your Network to identify the following

1) The first two numbers is RBI (Reporting Body Identifier) = who registered that type of phone
( verify here: http://en.wikipedia.org/wiki/Reporting_Body_Identifier )

2) The next four numbers is TAC (Type Allocation Code) = what type of unit and its complete specifications

3)The next two numbers is FAC (Final Assembly Code) = who manufacture it

example :-

01 AEG
04 Samsung
07 Motorola
10 Nokia
30 Ericsson
41 Siemens
50 Bosch
51 Sony

4) The next six numbers is the Serial Number of the Phone

5) The last number is sort of a check sum, that verifies the previous numbers

Combined a total of 15 numbers is used by your network to get the complete information about your phone that is used against their database of Blacklisted phones and final approval to connect to their network, IF they were inaccurate or had complaints (like being stolen, not paid telecoms dues etc) it will be rejected and BLOCKED immediately from connecting to that Network

You can verify all this by entering you IMEI here

http://imei-number.com/imei-number-lookup/
&
http://www.numberingplans.com/?page=analysis&sub=imeinr

And also here to check if it is blacklisted

http://www.imeidetective.com/englishaparativbazi.php

Your IMEI is also needed for networks to BLOCK your phone when needed as well as ANTI theft apps.

Hence if your IMEI changes or gets lost, it may fail to connect to the network, depending on the restrictions of that network provider.

It is clear that Flashing custom ROMS can cause your IMEI to Change or get deleted as they may be ported from another manufacturer or from another version of the same manufacturer as the IMEI embedded in the chip of your phone.

IF you want to AVOID this problem, safe you EFS folder the moment you think of Flashing any ROM that is NOT the original Firmware for that phone

It is noted that to resolve this problem you have to return to its original firmware to recover your embedded IMEI and do a progressive upgrade . eg. from GingerBread to ICS before going on to Jelly Bean.
