How is that for irony? Going to Black Hat and getting hacked? Here are
some tips from our friends at Websense Security Labs and Qualys on how
to make it hard for the hackers to make a fool out of you.
If you are at a security conference, you have to accept that there is
someone probing the network for security vulnerabilities, sniffing
network traffic to see who is sending sensitive data on the web without
encrypting it, and pwning any attendees who didn't pick a strong password
for their accounts. Some of the brightest minds in security are in
attendance at Black Hat and DefCon. For the rest of us, it is in our
best interests to be paranoid and exercise some caution.
Before You Even Get to Vegas
Security paranoia
and best practices kick in long before you get to Las Vegas. First and
foremost, make sure you have patched the operating system, browser, and
installed software. Make sure your antivirus and security software are
fully patched and up-to-date, too.
Go ahead and delete your cookies and clear the Web browser history
and cache. Cookies contain a lot of information about you. If your
notebook is stolen, the last thing you want is for the thief to be able
to get access to information about you or your online activity.
If you don't already, encrypt sensitive files on your hard drive. If
possible, go with full-disk encryption so that you don't miss an
important piece of data.
Make a full backup of your computer and other devices and leave the
backups at home (or if you trust the cloud, online). That way, if you
accidentally lose your device, or if it gets stolen, you at least have
your data waiting for you.
When you get home, wipe your machine (in case you accidentally got
hacked or infected) and revert back to this clean backup. While at the
conference, consider saving to a cloud server or your own personal
removable drive. Don't ask around for someone to give you a USB key at
the conference; that's just asking to get an infected drive.
I actually just take a stripped down machine, with nothing on it from
my normal usage. Just a patched OS, and whatever information I will
need this week.
Just in General, Be Safe
While we are at it,
while you are at Black Hat or DefCon, if you are prompted to install a
patch or update, be really cautious. Odds are that it will be malicious.
We said it once, we will say it again. Do not accept storage devices,
USBs or files from people you don't know. If you find a USB drive in
your bag but you don't know how it got there, don't just pop it in to
your laptop "to see what's on it."
Be careful about using ATMs, especially near Caesars Palace or Rio,
where the conferences are. Anyone can install card skimmers. With Barnaby Jack's tragic death just last week, I am half-expecting someone to set up a fake ATM in his memory.
Device Security in Vegas
Keep an eye on all your
devices. If you leave it behind, it may get stolen. It may also
encourage someone to compromise it and leave behind a small present
instead.
Turn off Bluetooth and Wi-Fi on all your devices. Make sure none of
your applications can automatically turn them on. It may be best to
leave any radio-frequency identification (RFID) enabled devices, such as
your work badge, passport (some counties) or even some credit cards at
home, or in your hotel room. If your phone has
near-frequency-communications (NFC) chip, turn that off, too.
Do not charge phones, computers, or other devices in public charging
stations. We've seen demonstrations at Black Hat where these stations can be hacked
to link to your device and slurp data without your knowledge, or infect
the device. An option is to invest in a portable battery pack that
charges independently that you can use while on the go.
Network Security in Vegas
Be careful about
connecting to wireless networks. It's not hard to set up a Wi-Fi
Pineapple, a network access point that can sniff out your activity. "Be
wary of the wireless networks throughout the venue, and your entire stay
at Black Hat," Websense advises. In fact, when you can, stick to using a
wired connection, especially in the hotel.
Use your VPN at all times! Connect to work servers over VPN, and if
you don't have one, use any one of the VPN services we have looked at.
We like VPNBook and Cyber Ghost VPN for free VPNs, although the ad-supported version of AnchorFree's HotSpot Shield is good, too.
Avoid sending sensitive data while onsite. "I avoid accessing data at
all, but if you need to, use a VPN on a laptop to be safe," says Andrew
Wild, CSO of Qualys.
"People think the cell phone is safe, but it's not. There are going to be two presentations this year where people are using a femtocell base station
in a man-in-the-middle attack," says Wolfgang Kandek, CTO of Qualys.
"Someone can put up a fake cell tower close to you, in the next room, so
the air card would connect to it."
Consider sticking with 3G or 4G connectivity, if you can. I use my
Android device as a portable hotspot, but that femtocell talk by iSec
Partners this week may scare me off that option, too.
I grabbed a burner phone, because I didn't want to lose any
information on my device. "If you are really paranoid, you can always
leave your computer and devices at home (since hotel locks and even room
safes can be hacked)," says Kandek.
But that's no fun. Black Hat and DefCon are full of great
presentations and everyone is ready to share everything they know. Just
be aware, think about security, and have a good time. Look for SecurityWatch if you are there and say hi.
