Like all forty-year-old know-how, SMS is antiquated in comparison with its trendy counterparts. That’s particularly regarding on the subject of safety.
The World Has Modified, However SMS Hasn’t Modified With It
In keeping with a current 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 cell provider networks. This could enable them to learn the contents of SMS messages, together with delicate info resembling 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 professional sender. This can be utilized to trick customers into clicking on malicious hyperlinks or revealing delicate info. And since provider networks have independently developed their approaches to deploying SMS texts over time, the shortcoming for carriers to change popularity indicators to assist determine fraudulent messages has made it powerful to detect spoofed senders distributing probably malicious messages.
These findings add to the well-established details about SMS’ weaknesses, lack of encryption chief amongst them.
Dekra additionally in contrast SMS in opposition to 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 dearth of safety protections SMS offers and have repeatedly exploited its weak spot. Each novice hackers and superior risk actor teams (resembling 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 in opposition to customers and firms 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.

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

The continued evolution of the cell ecosystem will rely upon customers’ capacity to belief and really feel secure, whatever the cellphone they could be utilizing. The safety of the cell ecosystem is simply as sturdy 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 cell ecosystem, we collectively owe it to all customers, throughout platforms, to allow them to be as secure 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.
Right this moment, most world carriers and over 500 Android system 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 trade strikes in the direction of an answer to an issue that ought to have been mounted earlier than the smartphone period ever started.
