Let's Go Phishing!

Phishing is a tried and true method of mischief online. It has been going on for almost two decades.

The basic principal behind phishing (pronounced Fishing) is to present a person with a seemingly legitimate web portal and then trick them into giving up personal information (such as username and password).

A classic phishing tactic is to send an email to a person containing an authentic looking email from a reputable organization. Many people are unaware of how easy it is to manipulate email transactions. When sending an email, the email client application (or API) puts the sending address in the message. So, this data can be set to whatever the phisher wants. So, the email could look like it came from a legitimate email address like [email protected] Here is an example to demonstrate how simple creating this is using C#:

MailMessage message = new MailMessage();
message.From = new MailAddress("[email protected] microsoft.com");
message.To.Add("[email protected]_domain.com");
message.Subject = "Thank You for your purchase!";
message.Body = "Thank You for purchasing $20,000 of products!";

SmtpClient smtp = new SmtpClient("smtp.MailServer.net");
smtp.Send(message);

 

Notice how the from email address was put there by me! It can look really legitimate! I can also build a mail server and write a program to send this out to as many email addresses as I want.

The most common forms of phishing are emails that contain a “purchase receipt” of some kind. This is likely the kind of email a person will take a look at, especially if the invoice or receipt is for several hundred dollars or more!

There will almost always be a link that says something like “Click here to cancel this order.” After clicking this link some JavaScript may execute to extract information about your email account and email client (if possible, your machine). After this link launches a web browser, it will present you with some sort of login screen. Watch out for ActiveX controls trying to install itself on your computer! This can be used to place a virus or spyware/malware on your machine. AND YES.. MACS CAN GET VIRUSES AND MALWARE!!!!

This may look exactly like a legit website, but one tipoff is that the URL will not look real. So instead of https://www.microsoft.com/login it may say http://microsoft.somesite.net/login. Even though Microsoft may be in the URL, take a look at the domain: somesite.net. That is what you are actually connecting to. Some phishers like to get cute and use IP addresses to try and fool their potential victims. Just know… a legit site will NEVER use an IP address to send to an email recipient.  Websites like Amazon.com, Expedia.com and even WiBit.Net use their domain name to market their business, so they would never want to hide this. Also, HTTPS is not enabled, and most legit sites would use HTTPS. Hmm… Suspicious?

After an unsuspecting person sees this website, they may enter their username and password and click login. At this moment, the phisher has your credentials. Many times the follow up website never loads at all, or it forwards you to the REAL website. You’ve been pwned!

I was inspired to write this blog after a ton of people I know got this email:

 

 

This email went out today to, probably, thousands of people. It says that they made a $699.99 purchase on iTunes. The product name is very strange and non-descriptive. Right below it is a Cancel Order link. This link will take you to a website and try to get you to give up your iTunes credentials.

Be careful WiBitters! Don’t let these jackasses scam you!

Are You a Polyglot Developer? Strive for it!

Last week I came across an interesting word “Polyglot”. It was used to describe a programmer that uses no single programming language more than 50% of the time.

Will the real WiBit.Net please stand up?

So….this is awkward. I like to troll Twitter.  I enjoy the massive conversation and all that.
