Has Someone Put A Backdoor In My Software?

Creating software can sometimes seem a little bit easier than it actually is in real life.

Back in the day, people used to see software builders as nerds and people who were out of step with the rest of society but now, with the integration of the internet, the people who build software, especially web sites, are having movies made about them and they are considered eligible bachelors by many females.

But what the new found appreciation of people who build software fails to show is that creating secure software is very hard.

You have to account for a bunch of different possibilities.

This is especially true for software that is going to be used by millions of people. You can never guess how they are going to interact with the software, so your software can never be 100% safe.

One of the biggest threats when it comes to software is someone being able to put a backdoor in it.

Either someone who is working on the software with you or after the software is released; someone was able to manipulate a part of your code to open a backdoor.

Who Would Put A Backdoor In Your Software?

There are many people who would like to put a backdoor in your software, especially if it is a very popular piece of software.

If you have a web-based piece of software then someone would create a backdoor so that they would be able to see the user’s information that you have on file.

Or they can manipulate a piece of the code that is on the site and make it send the user somewhere else.

This way, they may be able to trick the user into getting information from them or, at the very least, get them to click on the ads at the place that they sent them to.

Most of the time, a backdoor such as this is going to be done for financial purposes and nothing more than that.

Another person that would put a backdoor into your software is someone who works with you and may be disgruntled.

There are plenty of times at the job where someone can feel unappreciated and they lash out by trying to sabotage the project (see “logic bombs“).

This is why you must always be aware of the feelings that some people may have that are working with you.

You do not want anyone to get to the point that they would do this to your project.

Security Audits Can Help You Avoid/Detect Backdoors

There are plenty of tools that are out there that will help you search for a problem with your code.

There are certain functions in the language that you wrote the project in which can help you find out if a backdoor was written or not.

The software will look for these functions and give you a chance to review the code that they are used in.

Make sure that you always are aware of what other people are writing in your code and also make sure that you keep a good security audit of software like a web site that might be facing the public.
