Phishing attacks are becoming more and more accurate and well-done thanks to the huge numbers of website that accept payments via CC (Credit Card). Telco operators are one of the favorites target of cybercriminal because of the amount of financial data required to activate a plan, top up your credit or buy a new phone online. Italian Telco operators TIM and WIND are not new of these attacks. Below a brief analysis of the clone-kit (ready to use kit uploaded by criminals to easily create a phishing website in a few seconds).
Clicking on the link the websites shows the form to fill to recharge your phone and have 50 euros for free.
Going deeper, and analyzing the URL it’s possible to retrieve more informations and see that the server presents several holes to hack into it. Found! The clone-kit is still there.Let’s have a look on it.
The kit is composed by many files,but the logic is inside the .php files:
best.php is the first one who is responsible to generate the random URL viewed by the user.
secure.php is responsible to save the collected informations like:
- phone number
- CC number
- Expiration date
And to show the Verified by Visa PIN request to authorize the payments.
The code shows that the PIN is acquired and sent to the next page done.php, responsible to save/send the leaked data. As we can see from the code below the data are stored inside an HTML file on the hacked server and sent by email to the “phisher”.
Reading the file on the web server is possible to retrieve all the victims’ CC data.
The first raw is an example triggered by the attacker to check if everything works fine.
Be careful. Phishing is the most simple but the must effective attack.
