At the Black Hat conference, a presentation centreed around
BBProxy, a hacking program that can take advantage of the trust
relationship between a BlackBerry and an enterprise's internal
server to hijack network connections.That, coupled with recent warnings of imminent mobile virus
outbreaks, is cause for alarm. SearchMobileComputing.com recently
spoke with George Tuvell and Neil Book, respectively CEO and
president of mobile security vendor SMobile Systems, to determine
which mobile threats are real and which are myth. The pair also
noted the havoc that BBProxy can wreak.
With mobility the way it is today, what do you see as the
biggest actual security threat?
George Tuvell: I think the biggest threat … both to the carrier and
to the end users is really the fraudulent services charges. We're
moving into a mobile commerce world where your phone is becoming
your digital identity. Not only is that going to be storing your
personal information on your own device or in chips, as they are in
Japan today, but also credit card information. You have the ability
now to make a payment with your phone by just hovering it over a
device; you can also use SMS messaging, text messaging, for
payment. I think that now we have that platform, you're going to
see more and more threats and attacks toward that, trying to use
the phone as a form of payment or [for] fraudulent service
charges.
What kind of impact can that have at an enterprise
level?
Tuvell: At an enterprise level or a consumer level, you're going to
have fraudulent service charges on the users' bills. It's really
independent of the end user. Multiple service charges, messaging
fees … it has a financial impact if it's directly related to your
bank account. I can create a cluster of problems ranging from the
consumer to the enterprise.
Neil Book: This creates a huge problem for not just the end user,
the enterprise or the consumer, but [for] the carrier as well. For
example, when fraudulent charges appear on your bill, the first
person [you are] going to be calling is the carrier. That's going
to drive up the carrier's support costs; they're going to have to
spend more time on customer care. It's going to create customer
churn. It's going to create the image that they don't have a
(quote-unquote) secure network. Along with a direct impact on the
consumer and the enterprise, it can have a tremendous potential
impact on the carrier as well.
What do you see as the biggest mobile security
myth?
Tuvell: I think the biggest myth is "the world is ending now"
theory. Some people out there are saying the threat is so big right
now it's an epidemic and everyone has to run and protect
themselves. It's not there yet. I think it's happening, it's
increasing. We're seeing proof of concepts; we're also seeing the
mobile payment types of viruses we're talking about that have hit
today, but primarily in the open operating systems platforms. Some
other vendors and people today have been over-hyping the threat,
saying it's really a major problem today, and it's not. It's not
there yet. I think that in the next 18 months, we're going to see a
significant increase. We've seen it year over year exponentially
already. There is some over-hyping going on and some
fear-mongering, and that's something that's just not where we are
today.
You mention that fraudulent charge attacks are the biggest
threat that's looming right now. What's available to protect
against them?
Tuvell: Our products and our solutions are geared toward protecting
the user experience and the user identity. When you look at what
the operating system vendors and the enhancement vendors are doing
today around security, they're trying to do some things like
provide basic encryption. Symbian, in the new version of [its]
operating system, now has Platform Security, which protects a lot
of the core operating system; it restricts third-party access to
some of the core functionality, which can be used in a malicious
way.
The problem is, the operating system can be secure, but it's
really the user's data and the user's information that sits on top
of that, and the applications that they're using, which are at
risk. It doesn't matter how secure you can make the OS itself. The
hackers aren't worried about bringing down Symbian, they're worried
about getting your information and manipulating it to their
advantage. And that is never going to be protected with a basic
operating system. You [will] always … have to have that layer of
security to protect the user experience. And that's what we do.
That's really where you have to start with mobile security. You
have to look at it from a user-experience perspective.
Protecting at the OS level is a nice segue into the BBProxy
(a BlackBerry vulnerability revealed at the Black Hat conference).
Can you explain what BBProxy is and what it does?
Tuvell: The BlackBerry Proxy [BBProxy] basically allows access to
an enterprise network via the BlackBerry. What happens is that the
BlackBerry will install this virus -- the BlackBerry Proxy. It's
not actually a virus, it's a security tool which has a
vulnerability to do this. You install this tool on the device; the
tool then can connect to an outside connection, to an external
connection -- say, my laptop. It makes a connection over the
Internet to my laptop. Now my laptop has a connection with that
BlackBerry. I can now access all of the connections that BlackBerry
has access to. If that BlackBerry is connected to the corporate
network during various functions, I now have access to that
network. That's the overall threat. Basically, now you have an
entry point from an external source into an enterprise network.
What steps can a company take to prevent against
BBProxy?
Tuvell: What [enterprises are] trying to do today is to say we're
going to restrict or limit your access. IT security administrators
say we'll just eliminate Internet access and not have to worry
about it. That type of thought process is really limiting the
BlackBerry user experience and the productivity it provides. It's
there to provide increased productivity, and if you take away those
functions, you're limiting your investment.
So, basically, what we've done is we've provided a security
solution at the handset level which still allows the enterprise and
the users to get the full access, to get the full capabilities and
the full experience [while] at the same time providing protection
against these known threats. We have an engine that runs on the
BlackBerry that monitors malware [and] illegitimate connections and
can provide security around that.
What could a worst-case situation be when dealing with this
BBProxy vulnerability?
Tuvell: The worst-case scenario is that it's a proxy, so it allows
you access to all of the resources the BlackBerry has access to. As
an enterprise, you're allowing your users access to email, which is
the No. 1 function today for BlackBerrys -- you basically have
access to the email system of an enterprise or corporation. You
could send out mass email attacks with worms or viruses from the
BlackBerrys. You also have access to their email servers. It
depends on what they're allowing access to. Some enterprises allow
access to database systems and other proprietary file systems with
customer information. It really depends on what level of access you
get today. Ninety-nine percent of the people using it will have
email access. It's basically a vector of attack into the enterprise
email system, which is today where we see most of the viruses on
the PC.
What really is the state of mobile security and mobile
devices? I've talked to people who have compared it to the PC world
in the 1980s in terms of viruses. You mentioned before that there
is a lot of fear-mongering going on, but is this threat
real?
Book: To use your comparison to the PC world, what we saw in the
'80s, it took probably 15 to 20 years before PC viruses began to
have a real financial impact on the marketplace. We've seen a much
quicker progression in the mobile virus world. I think the first
mobile virus was released in 2002 or 2003. Since that time, it's
already had a financial impact. I think we've seen a much quicker
progression than we did in the PC space….
When we're talking to customers or we're out there talking to
carriers, we're constantly telling them it is not an epidemic, not
a pandemic today. But we believe it certainly can be tomorrow. Now
it's very important as these operators begin to open up their
networks -- and their users are going to have the ability to go
out, for example, and browse the Internet and start downloading
third-party applications -- to provide that protection and put that
protection in place today before it does become an epidemic.
I personally believe [that] over the course of the next 10 to 18
months we're going to really start seeing a significant number of
viruses being released that have the ability to spread quickly and
to have a real financial impact on the marketplace. Today, for
example, it's there, particularly in Europe and Asia, but we're
seeing new releases coming out all the time.
Is there any specific operating system or platform that seems
to be targeted?
Tuvell: The dominant platform today has been the Symbian operating
system. It's 70% of the smartphone market. It's an open operating
system. And we've seen most of the MMS Trojans, SMS dialing
Trojans, these types of attacks, happening on that platform.
Aside from the financial aspect, are there any other negative
effects that could come from mobile viruses, such as devices being
rendered useless? What are the potential outcomes?
Tuvell: Aside from the charges, like you just said, the devices
could be rendered useless. It's an on-demand type of world in
mobile. It's all about right now: I want my service, I want my
messages. It's real time. The moment you don't have access to that;
the moment you can't make a voice call or you can't make a data
connection to check your email, it's a big pain point for the end
user. That's really on top of what the carrier experiences in terms
of loss of revenue for that downtime, you've now lost your access
to services. If I'm an enterprise, I've lost my productivity.
There's a pain point both from the enterprise/consumer side and at
the carrier level just from denial of service.
In Asia, two years ago, the first CommWarrior virus, which was
an MMS Trojan [and Bluetooth], went around to 30 different
countries around the world. We've seen multiple variants of that
today, but when it first came out, it actually took down a phone
operator in Brunei … and actually required the operator to recall
the handsets and re-flash [them]. It was an enormous cost for them
bringing the handsets into the flashing centre, re-flashing them,
resetting them and sending them out.
What should really be front of mind for enterprise, mobile
operators and the people who are in charge of managing and securing
these devices for their mobile workforces?
Tuvell: The plan needs to be, you have to have something in place
today to protect yourself. A perfect example of that for the
enterprise especially is the BlackBerry Proxy. This is something
that came out very quickly and it affects all BlackBerrys, it is
not limited. Enterprises have to have a solution in place, but they
[haven't deployed a solution] to protect them from that. The point
is that it can happen very, very quickly.
Why don't enterprises and companies have any solutions in
place?
Book: There are some enterprises that do have something in place.
Enterprises really haven't mandated it yet, and that's simply
because the financial impact has just not been there, and we
haven't seen a huge proliferation of viruses going out and
affecting corporate networks and taking down devices. However, we
are starting to see in certain parts of the world that once it does
enter a market and once the awareness is created, we are going to
see enterprises taking steps to remedy this problem. We're starting
to see that today. Since the announcement came [this month] about
the BlackBerry vulnerability, our phone has been ringing off the
hook from enterprises looking to deploy our antivirus solution on
that platform. It's all a matter of awareness. As the awareness is
created, you're going to start to see the enterprises taking those
steps to protect themselves.
Is there anything further you'd like to share with our
readers about mobile security?
Tuvell: There used to be a lot of closed systems, and everything
was closed off. Feature phones did not have Internet access. What
we've seen in a very short period of time [is that] some of them
have become very smart and they're very capable of Internet
connections and peer-to-peer applications. Basically, what's
happening is the Internet is now coming to your mobile phone. And
there's really no stopping that. We're going to be there at [the
latest] within the next two years in a smartphone-dominated market.
Both enterprises and consumers are going to have to do something
within the 18-month time frame. They're going to have to do
something to keep themselves protected because it's going to be a
dominant IP Internet world in terms of mobility, and a slew of new
attacks and new threat vectors are going to come with that. We're
at the early stages today, but it's going to be a very short
ramp-up time.
