What is smishing and how to prevent it?

Smishing, derived from “SMS” and “phishing,” is a type of cybercrime that uses deceptive text messages to manipulate victims into divulging sensitive personal information such as bank account details, credit card numbers, and login credentials. As a variant of phishing, victims are deceived into giving sensitive information to a disguised attacker. SMS phishing can be assisted by malware or fraudulent websites. It occurs on many mobile text messaging platforms, including non-SMS channels like data-based mobile messaging apps.¹

Smishing is a serious threat for healthcare professionals because:

• It exploits the trust and familiarity that people have with text messages, making them more likely to respond or click on links or attachments.
• It can bypass the security features of email platforms, such as spam filters, antivirus software, or encryption.
• It can target specific individuals or groups, such as patients, staff, or vendors, by using personal or professional information obtained from social media, public records, or data breaches.
• It can cause financial loss, identity theft, or data breach, depending on the type and amount of information that is stolen or compromised.

You can prevent smishing by:

1. Being alert and suspicious of any text messages that ask for your personal or financial information or that urge you to take immediate action, such as clicking on a link, calling a number, or downloading an attachment.
2. Verifying the identity and legitimacy of the sender, by checking the phone number, the spelling, the grammar, or the tone of the message, or by contacting the sender through another channel, such as email, phone, or website.
3. Avoiding clicking on any links or attachments in the text messages, unless you are sure that they are safe and relevant. If you need to access a website, type the URL directly into your browser rather than following a link.
4. Using a reputable antivirus or anti-malware software on your mobile devices, and keeping them updated regularly, to protect them from any malicious content that may be downloaded or executed through smishing messages.
5. Reporting any suspicious or fraudulent text messages to your mobile carrier, your IT department, your security officer, or the OCR, as required by law or policy. You can also forward the messages to 7726 (SPAM) to alert your mobile carrier.
