Background Info

Smishing (short for SMS Phishing) is a variant of phishing email scams that uses Short Message Service (SMS) systems to send out bogus text messages. Also written as SMiShing, SMS phishing made recent headlines when a vulnerability in the iPhone's SMS text messaging system was discovered that made smishing on the mobile device possible.

Smishing scams frequently seek to direct the text message recipient to visit a website or call a phone number. At which point, the person being scammed is enticed to provide sensitive information such as credit card details or passwords. Smishing websites are also known to attempt to infect the person's phone with Malware.

SMS phishing uses cell phone text messages to deliver the bait, persuading people to divulge their personal information. The "Hook" (method used to capture people's information) in the text message may be a website URL. LUCY offers the possibility to simulate such attacks. To create a smishing campaign is the same as creating a regular Phishing Campaign. The only difference is that within the message template (former e-mail template) you have to select SMS instead of email as a delivery method.

How is LUCY sending SMS?

LUCY has a built-in API that will connect to a centralized LUCY gateway when initializing SMS delivery. The gateway will first verify if the LUCY client has sufficient credits and is allowed to send SMS. If all checks pass, our gateway will connect to an international provider using a second API (MessageBird). This provider will send messages with the settings defined in your LUCY server.


American Clients:

In the United States, specific numbers are to be used with our platform under the 10DLC regime that requires registering numbers and using them for approved purposes. Numbers and fees associated with the 10DLC regime are paid for and managed by ThriveDX Enterprise. From a regulatory perspective, a 10DLC number is approved and assigned to a specific corporate entity for specific appropriate purposes. Broader 10DLC overview as follows -

Under this regulatory regime, there are no acceptable use agreements with specific carriers in the same way that using a credit card does not require an individual agreement with every business - the 10DLC number approved and used for specific purposes is like a passport as a verified credential to use an asset for a specific reason. Similarly, a 10DLC number is revoked if the number operates for purposes outside of its stated and approved purposes. This is the same as if a mail server spoofs email senders, and the same as having your passport no longer recognized as valid.

Other Countries:

Similarly, nations the world over have their own specific and differentiated regulatory requirements. These can limit everything from sender names, to times of day when messages are permitted, to whether links are permitted in messages, to if numbers can be ‘spoofed’.

For any of the above reasons, messages might not be delivered. In case of doubt, before testing, please consult the list of country restrictions here -

System Setup

All SMS traffic will be routed via our default provider, MessageBird.

Due to strict regulations in France, we've integrated an Alternative French provider to enhance our service. Kindly note, utilizing this provider requires additional preparations for whitelisting. Ensure the following requirements are fulfilled prior to initiating testing.

Campaign Setup

A Smishing Campaign is not different from a regular phishing campaign. Most templates can be used in the same way. The difference is only the delivery method: within the scenario (Base Settings –> Scenario Settings –> Message Settings) you can use as a delivery method either "mail" or "sms". Choose "SMS". As a sender, you can put a name or phone number (use always the phone number with the country code: example 49 xxx). The actual phone number should have no "00" and "+" in front, i.e. 41796959611 (41 - Switzerland country code) and not 0041796959611 or +41796959611. See

If the phone number is saved in the recipient's contacts, it will show the corresponding contact information upon arrival of the SMS.

Next, you will need to enter the phone number in your recipient's list. Don't forget to also set the correct language (the language should match the language chosen in General Settings (Base Settings –> Scenario settings –> Base Settings).

Automated URL Shortening

When you place the %link% variable within the message body and your scenario uses a public domain name, it will automatically be shortened. The link will look like "” to fit into one text message. If you use an IP address for your landing page the link will be not shortened.

Known Issues

  • Issues with specific countries: in certain countries, SMS spoofing will not work at all or SMS might only arrive if the sender is using a different country code. For example: in Belgium, the SMS sender will get replaced by a general number like "8850" when using a different country code.
  • Issues with Delivery (sender):This usually means, that your provider did not accept your senders ID. Try different variations to solve this. Example: if your sender number is 0041793531111 (where 0041 is the country code, 79 the prefix and 3531111 the phone number) you could try to send as +41793531111 or 0041793531111 or +41.793531111. If all variations do not work, please leave the sender field empty. Our message provider will then replace it with the default sender name. If the message gets successfully delivered with the default message, you can try to enter your own sender name (e.g. Jon Smith) instead of a phone number.
  • Issues when spoofing with same provider: Spoofing a message within same provider within the same country might not work. For example: if you want to send a spoofed message from a cell phone using “o2” to another cell phone using “o2” the message won't arrive. But if you send the same message from a phone using “telekom” to a cell phone using “o2” it will work
  • No credit: In order to use the Smishing feature you will need enough credits. To see your current balance go to the license page in LUCY.
  • Issues with delivery (recipient number): sometimes the message is not delivered, because the phone number under the recipient is saved with the wrong format. Make sure recipients phone number always has the country code included.
  • Issues with specific countries: in certain countries SMS spoofing will not work at all or SMS might only arrive if the sender is using a different country code. Example: in Belgium the SMS sender will get replaced by a general number like “8850” when using a different country code.
  • Delivery issues (content): Unfortunately some operators block links in SMS sometimes (for example, in Russia it's nearly impossible to send a link in SMS). You could try to remove http link or create a plain SMS without a link to test this feature.
