How many of the people who follow you on social
media sites really exist — and how many are lifelike avatars created by criminal
hackers?
An investigation by IT security company Symantec
unearthed dozens of fake profiles on professional networking site LinkedIn that
had been created by scammers posing as recruitment consultants. The apparent
aim of these fake profiles was to infiltrate business networks by making and
exploiting connections with reputable executives.
Personal and professional lines blur on social
media, where people are ready and willing to share information and curiosity
persuades the unwary to click on web links of uncertain provenance.
“These are places where we build trust quickly
with people who we believe share our opinions or enthusiasms — too quickly in
many cases,” says Elad Ben-Meir, vice-president of marketing at Cyberint, a
consultancy.
James Foster, chief executive of social media
risk company Zerofox, says a common social media tactic is for fraudsters to
assume the identity of someone’s colleague or business associate based on
information gleaned from their online interactions.
The criminals may attempt to persuade their
target to reveal system login credentials, divulge confidential company
information or to download malware on to their company computers.
“Once the door’s been forced open in this way,
then the potential for reputational damage is substantial,” says Mr Foster.
“Just as most businesses put in place technology measures more than a decade
ago to combat email phishing of their employees, I believe many will
come around to the idea that a similar approach is needed to address social
media risk.”
A study from IT security company Proofpoint, for
example, says one in five clicks on malicious website links occur outside corporate email systems, mostly on social media and mobile apps.
Hackers are also using social media to
manipulate customers. They pose behind fake profiles that represent legitimate
brands or as a company’s customer service staff to lure people into divulging
online banking passwords, provide personal details with the promise of free
gifts or money-off coupons that never arrive.
The same Proofpoint study, for example, found
that 40 per cent of Facebook accounts and 20 per cent of Twitter profiles
claiming to represent Fortune 100 brands were unauthorised by those companies.
In 2015, airlines including JetBlue, Southwest Airlines and
Virgin Atlantic had their brand identities hijacked by fake accounts on
Facebook in order to dupe users into sharing personal details.
Customers had thought they were entering a
lottery to win round-the-world, first-class tickets. While it is not known what
the harvested data will be used for, it could well be sold on to other
criminals.
In addition, fake web pages visited in order to
enter these “competitions” may well install malware on users’ devices.
“Brands get tainted by this kind of ‘customer
experience’, even though it’s clearly not the result of their own wrongdoing,”
says Mr Foster. “In these situations, the burden of . . . making things right
with the customer, typically falls to [companies].”
Digital Shadows, a UK-based start-up, monitors
social media sites, search engine results, online forums and the hard-to-reach,
encrypted “dark web”, home to cyber space’s murky side.
James Chappell, the company’s founder, says: “We
find spoof profiles, where hackers are impersonating employees and company
executives and compromising brand integrity. We find sensitive documents all
the time.
“Not every business faces the same risks, nor
every industry,” he adds. “But what most organisations have in common is a lack
of awareness of how widespread and serious the risks are.”
Where there is fear, there is an opportunity for
security providers, as services and products that offer to provide protection
from reputational threats will come at a cost.
Rick Holland, an analyst at technology market
information provider Forrester Research, says concern about the unknown dangers
is helping to drive what he calls the “cyber threat intelligence” sector.
Mr Holland adds he has already identified more
than 20 companies that are attempting to grab a slice of this potentially
lucrative market. It is likely more will join them.
