There are many different ways through which fraudsters can make use of SMS as the primary channel to execute their malicious intent. Let us take a look at the details about different types of SMS fraud and SMS fraud detection and prevention techniques.

SMS Spoofing

This type of SMS fraud occurs when the sender’s information on a text is altered so that the recipient sees an alphanumeric code or address rather than the sender’s mobile number. Though SMS Spoofing is not illegal and is being used by many legitimate businesses, it is also used by hackers to mimic messages from legitimate businesses. Some common examples of fraudsters using this technique are pretending to be from a bank or any trusted business/brand.

Since the sender’s address appears to be trustworthy, the recipients can easily be tricked to click on links, which may lead to the installation of malware or can extract personal information by redirecting to a phishing website.

Now, it’s clear that Smishing attacks make use of an element of spoofing which we have discussed above.

These types of attacks are getting sophisticated as fraudsters use different types of social engineering tactics to collect information about the target. This may include the address, credit/debit cards used, and banks with which the target is associated. The motive behind gathering this information is to create very realistic Messages so that the victim gets misled easily.

SMS Grey Routes

Though these routes do not impact the end user directly, they do have an adverse effect on the mobile SMS ecosystem. These types of routes are adopted by rogue mobile operators with the motive to A2P SMS messages as P2P traffic so that they can benefit from lesser rates. However, such a practice affects telecom providers as they are not being fully remunerated for the service provided to them.

SMS Spam

So ultimately, it is the responsibility of the SMS service providers to eliminate spam messages from their channel before it lands on the subscriber’s mobile phone.
