AdaptiveMobile reduces North American SMS SPAM by over 75% in 2013

DALLAS --(Business Wire)--

AdaptiveMobile, the world leader in mobile security firm, today announced a staggering 78.6% reduction of malicious SMS Spam in its customers' North American SMS traffic over the course of 2013. Working with leading carriers in the US market to implement the latest techniques in identifying, blocking and ultimately eradicating SMS Spam, AdaptiveMobile (News - Alert) today also identifies the five dominant mobile spammers in North America in 2013.

During the course of the year, AdaptiveMobile blocked more than 100 million SMS spam attacks, reducing the spam rate to be less than 0.01% in its customers' SMS traffic. Despite significant reductions, SMS Spam remains a challenge for carrier networks in North America and globally. Due to the defenses put in place in 2013, our intelligence shows that North America spammers are moving to send from less well protected email-to-SMS systems and from VoIP carriers, and spammers worldwide are using other messaging systems evidenced by recent attacks such as SnapChat.

Head of Security Operations for AdaptiveMobile, Cathal McDaid, says, "Mobile spam is not a random uncoordinated phenomenon, it is sent by known threat actors. These actors range from sophisticated multi-national criminal operations to small, local aggressive scammers. These are the groups that our analysts monitor, track, and ultimately work against. We call this activity "hunting," for obvious reasons. Internally, we give these groups code-names, as intelligence on these groups is key to nti-spam techniques against them, which can have a huge impact on the mobile spam ecosystem. Many of these hunts are still on-going, and frequently we have seen these targets shift strategy or terrain to hide from us, but here we will talk about the "Big Five" attacks in North America in 2013.

McDaid continues, "The Big Five for 2013 are specific, high-value, targets that we have hunted and reduced spam from, completely in some cases. There were other groups that were tracked and blocked during 2013 and onwards, but the Big 5 represented much of the spam over the course of 2013 and have been singled out for particular attention."

Note: to protect the integrity of ongoing operations, specific message content has not been shared, but the Big 5 are:

1. Phishing/US-O/LION
2. GiveawayScam/US-NE/LEOPARD
4. Marketing/US-SE/BUFFALO
5. Phishing/US-SE/RHINO

McDaid concludes, "We have been working hard with our carrier customers and industry partners throughout the year to identify and stop malicious mobile spam activity. The year have been marked by continuous targeted 'strikes' and takedowns against the most dangerous and prevalent spam types in North America. Mobile spam sent from cell phones is now a fraction of what it was reported to be in the past. However mobile spam continues to be received by cell phone users from less protected sources, and the mobile spammers that remain active in North America are some of the most determined and persistent in the world."
