How to find senders IP address from received mail
Emails are very important part of our communication systemWe think that we know everything about emails
we know how to compose email , how to attach a file , how to send it to others ,How to receive emails from others and many other things.This is all we know about emails.But this is not end of it .When you receive or send emails many other things are sent with it.
At this time when Email is progressively used for business and for many purposes, not to mention it is being used for phishing and other malicious intentions. It is of utmost priority to understand the other "messages" besides what has been sent or received by you.
Every email comes with a “Header” which is one part of an e-mail structure; call it DNA of the mail. It carries the basic fundamental information such as from whom the email comes, to whom it is addressed, date/time it was sent and the subject of the email. It is similar to an electronic postSeptemberk. Moreover, it also carries other detailed information which we usually don’t see.
This basic information comes in all brief/basic headers that most email programs automatically shows. This detail technical information can be viewed in a full header. All email programs can be set to show only brief header or full header and it is up to the users to set the program whether to view only “brief header” or “full header”.
Full header carries the information of the mail server’s name that the email passed through on its way to the recipient, and sender's IP address and even the name of the email program and its version used.
Knowledge of this information is essential for analysis and investigation purposes on cases involving email abuse, spamming, harassment, forgeries and mail-bombing. It is worth mentioning, understanding of this tool would definitely help people to counter these attacks, and save themselves from unwarranted consequences. Well, this information could not be found in a brief header.
Here we will take the case of Google mail and Yahoo mail to find out the full header.
Google Mail.
Using your id/password, login to Gmail. Open the mail for which you wish to find the full header of the sender. Click on the inverted triangle placed just next to Reply.

How to hide a file in image
1. Gather the file you wish to bind, and the image file, and place them in a folder. For the sake of this demonstration, I will be using
C:\New Folder
-The image will hereby be referred to in all examples as fluffy.jpg
-The file will hereby be referred to in all examples as New Text Document.txt
2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (secret.rar)
3. Open command prompt by going to Start > Run > cmd
4. In Command Prompt, navigate to the folder where your two files are by typing
cd location [ex: cd C:\New Folder]
5. Type [copy /b fluffy.jpg + secret.rar fluffy.jpg] (remove the brackets)
Congrats, as far as anyone viewing is concerned, this file looks like a JPEG, acts like a JPEG, and is a JPEG, yet it now contains your file.
In order to view/extract your file, there are two options that you can take
a) Change the file extension from fluffy.jpg to fluffy.rar, then open and your file is there
b) Leave the file extension as is, right click, open with WinRar and your file is there
C:\New Folder
-The image will hereby be referred to in all examples as fluffy.jpg
-The file will hereby be referred to in all examples as New Text Document.txt
2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (secret.rar)

Change your passwords on Computer Security Day
Most people keep the same password for too long and use it for too many purposes. So if you do one thing to mark Computer Security Day on Friday, change your passwords. If you do two things, change your passwords and vacuum your computer. These are among the tips from the US organisers of the global event, including Security Awareness Inc. and the Information Systems Audit and Control Association. Now in its ninth year, Computer Security Day exists to remind people to protect their computers and information. The day is on 30th November each year and the organisers list 53 ways that offices can participate. Suggestions include: * Check for viruses * Protect against static electricity * Vacuum your computer and the immediate area * Back-up your data * Post 'No drinking' and 'No smoking' signs in computer areas * Hold a discussion of ethics with computer users In a climate of high-profile security breaches, most notably HM Revenue and Customs' loss of 25 million records, protecting information to the highest standard has never been more vital to maintaining customer loyalty and business reputation.
