Spam’s new
shelter — cellphones
D. Young & Y.I. Kane
If
you thought your spam problems couldn’t get any worse, check
your mobile phone.
Cellphones are
becoming the latest target of electronic junk mail, with a growing
number of marketers using text messages to target subscribers in
Asia.
Mobile phone spam
has yet to approach anything like the volume of the e-mail
variety, but the problem is growing in a region where the average
user sends as many as 10 SMS (short message service) messages a
day.
"SMS spam is
certainly something that people are focusing on, particularly in
markets like Japan where it is a common problem," says Jeff
Bullwinkel, a spokesman for Microsoft Corp, which is spearheading
a worldwide anti-spam campaign. "It’s big in markets where
mobile communications are prevalent."
Mobile phone
companies were reluctant to talk about the trend, but evidence of
the problem abounds on the Website of NTT DoCoMo, Japan’s
biggest mobile phone company.
The site carries
cautionary words about a junk message regarding the need for
B-negative blood for a child’s operation, and instructions to
forward a chain-mail or face financial consequences.
The phone company
also warns of messages claiming to come from DoCoMo asking people
to send money to a particular bank account.
Individual users
face difficulty blocking such messages because of their random
origins, although DoCoMo lets users set accounts to receive only
messages from specified sources.
SMS spammers in
Japan typically find their prey by generating at random the e-mail
style addresses used for text messaging in the country, a DoCoMo
spokesman says.
DoCoMo — whose
users send and receive 10 messages a day on average — is
fighting SMS spam through measures such as blocking huge
quantities of messages that lack specified recipients, he adds. |
