Businesses and political campaigns are increasingly relying on SMS messaging for critical communication with customers and constituents. Businesses use SMS for sales, service, marketing, simple notification, and two-way conversation. Political campaigns use SMS to drive awareness, donations, and get out the vote.
As SMS has increasingly become a channel of choice for these use cases, hackers and bad actors have taken notice. SMS is a viable attack vector. The U.S. Federal Trade Commission calls SMS attacks a “Triple Threat.” There is even a moniker for these attacks – Smishing – a clever combination of the phrases “SMS” and “Phishing” (coined in a McAfee blog post, 2006).
