Like every forty-year-old expertise, SMS is antiquated in comparison with its trendy counterparts. That’s particularly regarding in relation to safety.
The World Has Modified, However SMS Hasn’t Modified With It
In keeping with a latest whitepaper from Dekra, a security certifications and testing lab, the safety shortcomings of SMS can notably result in:
- SMS Interception: Attackers can intercept SMS messages by exploiting vulnerabilities in cellular service networks. This will permit them to learn the contents of SMS messages, together with delicate info comparable to two-factor authentication codes, passwords, and bank card numbers because of the lack of encryption provided by SMS.
- SMS Spoofing: Attackers can spoof SMS messages to launch phishing assaults to make it seem as if they’re from a official sender. This can be utilized to trick customers into clicking on malicious hyperlinks or revealing delicate info. And since service networks have independently developed their approaches to deploying SMS texts through the years, the shortcoming for carriers to trade status alerts to assist determine fraudulent messages has made it robust to detect spoofed senders distributing doubtlessly malicious messages.
These findings add to the well-established information about SMS’ weaknesses, lack of encryption chief amongst them.
Dekra additionally in contrast SMS towards a contemporary safe messaging protocol and located it lacked any built-in safety performance.
In keeping with Dekra, SMS customers can’t reply ‘sure’ to any of the next fundamental safety questions:
- Confidentiality: Can I belief that nobody else can learn my SMSs?
- Integrity: Can I belief that the content material of the SMS that I obtain shouldn’t be modified?
- Authentication: Can I belief the identification of the sender of the SMS that I obtain?
However this isn’t simply theoretical: cybercriminals have additionally caught on to the shortage of safety protections SMS offers and have repeatedly exploited its weak spot. Each novice hackers and superior menace actor teams (comparable to UNC3944 / Scattered Spider and APT41 investigated by Mandiant, a part of Google Cloud) leverage the safety deficiencies in SMS to launch several types of assaults towards customers and companies alike.
Malicious cyber assaults that exploit the insecurity of SMS have resulted in identification theft, private or company monetary losses, unauthorized entry to accounts and companies, and worse.
Customers Care About Messaging Safety and Privateness Now Extra Than Ever

It’s Time to Transfer on From SMS
The safety panorama because it pertains to SMS is straightforward:
- SMS is broadly used
- SMS is definitely abused as a result of it has so few protections

The continued evolution of the cellular ecosystem will rely on customers’ potential to belief and really feel protected, whatever the telephone they might be utilizing. The safety of the cellular ecosystem is simply as robust as its weakest hyperlink and, sadly, SMS texting is each a big and weak hyperlink within the chain largely as a result of texts between iPhones and Androids revert to SMS.
As a cellular ecosystem, we collectively owe it to all customers, throughout platforms, to allow them to be as protected as doable. It’s a disgrace that an issue like texting safety stays as outstanding as it’s, significantly when new protocols like RCS are well-established and would drastically enhance safety for everybody.
In the present day, most world carriers and over 500 Android machine producers already assist RCS and RCS is enabled by default on Messages by Google. Nonetheless, whether or not the answer is RCS or one thing else, it’s vital that our business strikes in the direction of an answer to an issue that ought to have been fastened earlier than the smartphone period ever started.
