SMS Verification to Eradicate Smishing and Mobile Fraud

Malicious URL is blocked and mobile subscriber is kept safe.

Cellusys launches SMS Verification to eradicate smishing and mobile fraud

Cellusys and MetaCert pioneer the use of Zero Trust and real time security to help mobile network operators combat SMS phishing and fraud.

Cellusys, a leading telecom solutions provider, has partnered with internet security firm MetaCert to provide a world-first SMS security solution, using Zero Trust methodology to combat cyberattacks such as phishing, malware and financial fraud. 

During the COVID-19 pandemic, SMS is being used by financial services companies and government institutions to contact people offering assistance and advice. Many mobile networks offer subscribers ineffective or no protection against fraudulent SMS messages. Advanced SMS firewalls are able to block many large-scale smishing attempts, however none are able to detect every new threat. 

Phishing is favoured by cybercriminals because it’s cheaper, easier and faster to exploit a human, especially when working remotely, than it is to exploit a computer system or computer network. ‘Smishing’ (or SMS phishing) is a term that has been in common use since 2006.

Criminals are sending SMS messages claiming to come from government authorities demanding payment of bogus fines or offering fake financial help, while others use contact tracing as a means of tricking consumers into opening dangerous URLs. Tens of millions of dollars are defrauded from customers each year by impersonating banks across the globe, from Australia to Ireland.

According to a study by Google and the University of Florida, URLs used in targeted phishing scams like the one carried out on Twitter, only need to be active for 7 minutes for criminals to achieve their objective. 

URLs used in bulk phishing campaigns only require 13 hours to do most harm, the study found. Network operator Orange Poland also recently found that 80% of customers open phishing links inside SMS messages within the first 15 minutes, while only 10% wait until the following day, which demonstrates that SMS is a perfect channel to launch a fraud attack.

“300 million domains are registered every year, with a new phishing URL created every 20 seconds. It’s mathematically impossible for any company to detect and block every known dangerous URL before harm has been done. 

“Mobile phone users will always be exposed to fraud and malware as long as networks continue to focus on filtering out known danger instead of telling consumers when they’re safe”, MetaCert CEO Paul Walsh explains.

Mobile operators claim their ability to identify and block an attack “within 24 hours,” but Cellusys now provides a security system that works in real-time. With the new approach from Cellusys, every URL contained in an SMS message is checked against MetaCert’s threat intelligence system and links categorized as “dangerous” are immediately blocked.

Uniquely, “unknown URLs” are similarly assumed to be dangerous. Carriers can either redirect customers to a warning page, provide a strong warning SMS, or block access to URLs that are not verified.

This approach to web access reduces the risk of a phishing-led cyberattack by more than 98% because consumers are able to make better informed choices about who to trust whenever they open an SMS message. 

With an established presence in the carrier space and enterprise-grade infrastructure from Cellusys, consumers can now be protected from SMS-related fraud using the same approach thanks to their partnership with MetaCert.

“Giving subscribers this kind of visibility increases their loyalty to the network, and is a very different kind of smishing solution.” said Brendan Cleary, CEO Cellusys “Adding MetaCert’s technology to our portfolio has generated a great deal of interest from networks, as an enhancement to the anti-fraud capabilities of our SMS Firewall.”

“While the safety of consumers is our main priority, the increase in consumer trust should not be underestimated by carriers. Consumers who feel safe whenever they open a message with verified URLs will be more likely to trust and engage with brands. Being able to protect both consumers and brands at the same time is now a reality,” Cleary added.
