The email world, until quite recently, was an entirely trusting place. I took out a couple of lines you don’t actually need.Īgain: configurations vary maybe this won’t work on every version of PHP on every server. Note: These are actual lines of code used as an example in the online manual for PHP’s mail() function. You can forge emails with five lines of very simple PHP code: Without getting into all the pros and cons of PHP, I will say that it is perfect for email purposes. If I can figure it out, how hard can it be? (Which is also why PHP is often accused of being insecure.) Hey, I built a whole website content management system in PHP. It’s fast, easy, and used by about 90% of the people (like me) who don’t know any more about programming than they were able to pick up through Google searches and by stealing snippets of code published on various public forums. Still, this is the basic idea and it works in many systems.īecause I’m not very sophisticated about programming I use PHP when I need to code stuff for my personal websites. This doesn’t work in every version of Unix, and whether it works at all depends on how your system is set up (whether it’s connected to Sendmail, etc.). ![]() Type in a subject line and the rest of your message, press Ctrl-D when you’re done, and off the message goes. That creates a message that says in the From field. ![]() If you have a computer that’s set up with mail services - or you can telnet or SSH to a computer that has mail services - you can forge a from address with one line.

So the ease of faking emails from people is a major vulnerability.īut, you ask, why would I bother faking an email from “” when I could just register a fake lookalike domain (like ) and use that? Or create a Gmail account and give it a friendly name that looks like the CEO of a company? And email attacks (aka phishing) are how the majority (actually the vast majority) of cyberattacks begin. MCQ Practice competitive and technical Multiple Choice Questions and Answers (MCQs) with simple and logical explanations to prepare for tests and interviews.In my day job as the communications guy for ValiMail, I spend a lot of time explaining how easy it is to create fraudulent emails using an email address that doesn’t belong to you.Ī faked “from” address, in fact, how the majority of email attacks happen. Using the syntax described above, we can create three examples for the rand() function in PHP: ") Īs you can see in these examples, the first rand function generates a random number between 20 and 30, the second between 1 and 10,000, and then the third without a maximum or minimum number set. ![]() The correct syntax for using the rand function is as follows: rand() Syntax and examples of the Rand() function However, you can define a specific range to include higher numbers. If no max function is specified when using the rand() function, the largest integer that can be returned is determined by the getrandmax() function, which varies depending on the operating system.įor example, on Windows, the largest number that can be generated is 32768. The function rand() can also be used to generate a random number within a specific range, for example a number between 10 and 30. The function rand() is used in PHP to generate a random integer. In this tutorial, we are going to see how to generate random numbers in PHP. ![]()
