smishing<br />

service, ignore the message," advises<br />

Norton. "If you see any unauthorised<br />

charges on your credit card or debit card<br />

statement, take it up with your bank.<br />

They'll be on your side."<br />

HOW TO KNOW IF YOU'RE<br />

BEING SMISHED<br />

In general, don't reply to text messages<br />

from people you don't know. That's the<br />

best way to remain safe. "This is especially<br />

true when the SMS comes from a phone<br />

number that doesn't look like a phone<br />

number, such as a '5000' phone number.<br />

This is a sign that the text message is<br />

actually just an email sent to a phone.<br />

You should also exercise basic precautions<br />

when using your phone. Don't click on<br />

links you get on your phone, unless you<br />

know the person they're coming from.<br />

Even if you get a text message with a link<br />

from a friend, consider verifying they<br />

meant to send the link before clicking<br />

on it. A full-service Internet security suite<br />

isn't just for laptops and desktops. It also<br />

makes sense for your mobile phone.<br />

A VPN such as Norton Secure VPN is<br />

also one advisable option for your mobile<br />

devices. This will secure and encrypt any<br />

communication taking place between<br />

your mobile and the Internet on the<br />

other end. "Never install apps from text<br />

messages. Any apps you install on your<br />

device should come straight from the<br />

official app store. These programs have<br />

vigorous testing procedures to go through<br />

before they're allowed in the marketplace.<br />

Err on the side of caution. If you have any<br />

doubt about the safety of a text message,<br />

don't even open it."<br />

Almost all of the text messages that you<br />

get are going to be totally fine. However,<br />

it only takes single rogue message to<br />

compromise your security. With just a<br />

little bit of common sense and caution,<br />

you can make sure that you don't become<br />

a victim of identity theft.<br />

WHAT SMISHERMEN USE AS BAIT<br />

As Kapsersky Labs points out, texting is<br />

the most common use of smartphones -<br />

and so a rich source of pickings for<br />

smishers. Experian found that adult<br />

mobile users aged 18 to 24 send more<br />

than 2,022 texts per month-on average,<br />

that's 67 per day-and receive 1,831.<br />

"A couple of other factors make this a<br />

particularly insidious security threat,"<br />

warns Kaspersky. "Most people know<br />

something of the risks of email fraud.<br />

You've probably learned to be suspicious<br />

of emails that say 'Hi-check out this cool<br />

link' and don't contain an actual personal<br />

message from the supposed sender.<br />

"When people are on their phones, they<br />

are less wary. Many assume that their<br />

smartphones are more secure than<br />

computers. But smartphone security has<br />

limitations and cannot directly protect<br />

against smishing. As noted by WillisWire,<br />

cybercrime aimed at mobile devices is<br />

rocketing, just as mobile device usage is.<br />

However, while Android devices remain<br />

the prime target for malware-simply<br />

because so many of them are out there;<br />

and the platform offers greater flexibility<br />

for customers (and cybercriminals!)-<br />

smishing, like SMS itself, works crossplatform.<br />

This puts iPhone and iPad users<br />

at particular risk, because they often feel<br />

they are immune to attack."<br />

Although Apple's iOS mobile technology<br />

has a good reputation for security, no<br />

mobile operating system can by itself<br />

protect you from phishing-style attacks,<br />

argues Kaspersky. "Another risk factor is<br />

that you use your smartphone on the go,<br />

often when you're distracted or in a hurry.<br />

This means that you're more likely to get<br />

caught with your guard down and thus<br />

respond without thinking, should you<br />

receive a message asking for bank<br />

information or to redeem a coupon."<br />

The good news is that the potential<br />

ramifications of these attacks are easy to<br />

protect against. In fact, you can keep<br />

yourself safe by doing nothing at all.<br />

"The attack can only do damage if you<br />

take the bait."<br />

No financial institution or merchant<br />

will send you a text message asking you<br />

to update your account information or<br />

confirm your ATM card code, reiterates<br />

Kaspersky. "If you get a message that<br />

seems to be from your bank or a<br />

merchant you do business with, and it<br />

asks you to click on something in the<br />

message, it's a fraud. Call your bank or<br />

merchant directly, if you are in any doubt.<br />

Remember that, like email phishing,<br />

smishing is a crime of trickery - it depends<br />

on fooling the victim into cooperating by<br />

clicking a link or providing information.<br />

Indeed, the simplest protection against<br />

these attacks is to do nothing at all."<br />

As technology has developed and<br />

evolved, the ways in which scammers try<br />

to target people has developed with it,<br />

comments the Financial Ombudsman<br />

Service (FOS). "From fake websites to<br />

text messages that appear to be from<br />

a legitimate source, scammers will<br />

try a variety of ways to get personal<br />

information from you, in order to take<br />

money from your accounts, use the details<br />

you share to pretend to be you, or to sell<br />

on. As well as use of technology, we also<br />

see scammers trying to manipulate or<br />

exploit situations to build trust or create<br />

panic, to try to get people to divulge<br />

information over the phone, and<br />

sometimes even face to face.<br />

MULTIPLE TARGETS<br />

The FOS sees a wide variety of<br />

circumstances in the complaints that<br />

are referred to it and not just related to<br />

banking - "we know that fraudsters also<br />

look to target pensions, investments and<br />

insurances, too". The industry regulator,<br />

the FCA, has information on its website<br />

about avoiding investment and pension<br />
