SAN FRANCISCO -- November 14, 2012

“Mobile spam” has become prevalent, with the majority of U.S. adults who text
reporting that they have received an unsolicited text message, according to a
survey conducted online by Harris Interactive on behalf of Cloudmark among
2,475 U.S. adults aged 18 and older, of whom 1,801 were identified as texters.
Many U.S. adults who text are also not aware of the most appropriate response
to unsolicited messages.

The survey determined awareness of, interaction with and perceptions of “text
message spam.” An infographic summarizing the study’s findings is also

Findings from the survey include:

  *Most U.S. adults (72 percent) use their mobile phone to send and receive
    text messages
  *72 percent of have received an unsolicited texted message
  *60 percent of those who send/receive texts received “mobile spam” within
    the last twelve months
  *13 percent of U.S. adults who received an unsolicited text message clicked
    on a link in the message
  *9 percent of U.S. adults who received an unsolicited text message called a
    number provided in the message

Additional Key Findings:

Younger Adults Are More Vulnerable to Spam

The likelihood of engaging in risky behavior in response to unsolicited text
messages dramatically increases among younger people. Of those who received
unsolicited text messages, 20 percent between the ages of 18-34 have clicked
on a link in an unsolicited text message, compared with 7 percent of those 55
and over. Additionally, 16 percent of those ages 18-34 have called a number in
an unsolicited text message versus 3 percent of those ages 55 and over.

Uncertainty Surrounds Proper Procedures for Reporting Mobile Spam

A majority of U.S. adults who send/receive texts – 64 percent – said it was
important or very important that their carrier have a mechanism in place to
report mobile spam. However, 72 percent reported that they were unsure if
their carrier had such a process in place.

Furthermore, 41 percent of mobile users who send/receive texts reported they
would text “Stop” in response to an unsolicited text message. However, by
acknowledging spam messages, these individuals may unwittingly validate their
phone number for malicious senders, opening themselves up for additional spam

Reporting Service Helps Consumers Combat Spam

One avenue for reporting text message spam is the GSMA Spam Reporting Service.
Consumers can submit suspicious texts to this service by forwarding the
message to “7726” (S-P-A-M) for analysis. Powered by Cloudmark, the service
provides participating carriers with comprehensive reports that include
detailed information on spam content, senders and reporters, which carriers
can utilize to block numbers, helping to reduce further spam. Some of the
largest carriers in North America, including AT&T, Bell Mobility, Sprint,
T-Mobile and Verizon Wireless, offer the service to their customers.

“With the rising popularity of text messaging, U.S. consumers of all ages are
susceptible to receiving unwanted text messages, leaving them personally
vulnerable to future security threats. Spammers are constantly searching for
new ways to catch consumers off guard,” said Neil Cook, CTO, Cloudmark. “There
is a tremendous opportunity to help consumers learn how to effectively combat
spam and utilize the resources their mobile providers offer. Cloudmark is
committed to helping carriers and mobile providers to ensure the security of
their services, protecting users from mobile security threats and enhancing
the overall user experience.”

Survey Methodology

This survey was conducted online within the United States by Harris
Interactive on behalf of Cloudmark from Sept 25-27, 2012 among 2,475 adults
ages 18 and older (among whom 1,801 use a mobile phone to send/receive text
messages) via its QuickQuery product. This online survey is not based on a
probability sample and therefore no estimate of theoretical sampling error can
be calculated. This data was weighted to reflect the composition of the
general adult population.
