Humour
When the hunters get hunted
T A Balasubramanian reveals the entrapment tools for
hackers.
If you cannot fight them alone, join hands to sock them, says Danny
DeVito, CTO of Baffle Corporation, and a humanoid by design.
You, Papyrus Bytewala, CIO of Baffle, are, however, refreshingly human. You
are also caught up in the paranoid proceedings of the Hackers Gold Mine
Meet, or HGMM, which, in turn, is happening in a corner of the crowded Techno
Over-exposition of Geeks and Gizmos for Lazy Enterprises (TOGGLE). Standing
next to you is Gene Hackman, CEO of Virus Busters, seemingly transfixed by Dannys
brand new brainwave.
Go on, Danny, he urges. I see the beginning of a beginning
in OUCH, the Organisation of Unstoppable CTO Hackers. What a juicy name. Youre
a genius.
You were always perceptive, Gene, says DeVito,
slapping his friend on the back with a chuckle. Well, let me tell you
that CTOs of the world will be obliged to unite, and turn into de facto green
hats becoming new-age hackers themselves. They will be respected members
of OUCH, mark my words. They will turn smartly on their attackers, the one who
have been threatening corporate networks all these years, and chase them down
into their dirty nests and slam them with hacker-loving slimy spyware and evil
viruses that lurk and wait their turn to make those black hats smoulder.
Good strategy, Danny, you admit, wondering how your humanoid CTO
has already tuned in to the language of the alpha geeks. Not to mention the
modus operandi of nasty hackers. But how do we know that hackers are around
hacking inside our system? They dont leave their marks all the time, you
know. Besides, they are adepts at disguise, like the best espionage guys.
If every hour a burglar turned up at your house and rattled the locks
on the doors and windows to see if he could get in, you would hear it, Papyrus,
would you not? says Gene. I admit that hackers do not come in noisy
herds, rattling the disks, so to speak, but they do leave their mark. They leave
signs when they sneak in.
Well, Im glad to hear they do that, you say, quietly. How
do you catch these sneaks?
Honeypots, says Gene, with a broad grin.
Huh? Is that like the bait used for trapping bears? says DeVito,
scratching his head.
Precisely. Yes, honeypots use the same idea. Entrapment by seduction,
says Gene, winking. We lure the bears into the den by dangling irresistible,
lip-smacking offerings, and they, the fools, rush in where angels fear to tread.
Except that these fools are called bots the free-wheeling bits of code
that roam around on the Web, looking for easy prey.
How do they work, these honeypots? I mean, how do they know that there
has been an assaultor an attempt at one? you ask.
They work like detective evidence kits. You could say honeypots are forensic
tools that are a boon to guys like me who chase online crime. We use them to
collect statistics about popular attacks, to grab copies of malicious programs
that carry out the attacks and to get a detailed picture of how these attacks
are crafted. To the malicious programsthe botsscouring the Web these
honeypots look like any other computer. But in the backyard, the machines use
a battery of forensic tools to log what happens on them. They trap the smoke
from the smoking gun. Sometimes even the bullets.
This is wild, says DeVito, rubbing his hands gleefully. So
what kind of honeypots have you been setting up, Gene?
Quite a few of them, and we give them names like Allure and Passion.
Oh, inspiration from the perfume guys? you say.
A little, says Gene. But these alpha hackers are getting sharper
even as we chase them down. One indicator of how useful these entrapment tools
have become is that the most sophisticated hacker monkeys now make their vile
programs recognise when they have encountered Allure or Passiontrespassed
on a honeypot, I mean.
So how did Allure and Passion do it? you ask.
Well, Allure was a standard PC running Windoves that was made as secure
as possible, which we dubbed the host. This ran a software program which created
another virtual PC inside Allurecalled Passionthe guest.
So we had this big host and a little, innocent-looking guest inside her. Now
inside Passion, we installed an unprotected version of Windoves dressed up,
or configured, like any domestic PC. All sweet and approachable and irresistible,
I might add.
You virus hunters know how to get the fish, eh?
We live and learn, says Gene modestly. Passion turned out
to be pretty potent as it makes it easy to pause the virtual PC
or even roll it back to an earlier configuration. This proved essential when
recovering from an attack. Armed with some forensic software, Passion became
the honeypot. When we put this bait online it was like dripping honey on an
open farmyard.
What happened?
The bears came swarming over, says Hackman. On average, Allure
was hit by a potential security assault every 15 minutes. None of these attacks
were solicited, mind you. Merely putting the bait online was enough to attract
them. The fastest an attack struck was in mere seconds and it was never longer
than 15 minutes before the honeypot logged an attempt to subvert it.
Its a pretty crowded place out there in the farmyard, eh?
Absolutely full to the brim with mad black hatters. The majority of these
attacks were merely nuisances. Many were announcements for fake security products
that use leaks in Windoves to make their messages pop-up. Others were made to
look like security warnings to trick people into downloading the bogus file.
And we carry on with our computers without being aware of all this gruesome
activity going on under the board? you say.
There was much more than activity. At least once an hour, on average,
Allure was hit by an attack that could leave an unprotected machine unusable
or turn it into a launch-pad for attacking other PCs. Many of these attacks
were by bugs that appeared first many years ago. These die-hard survivors swamp
Net connections as they search for fresh victims and make host machines unstable.
Why are they still swarming around?
Because they have not been wiped out. They scan the Net so well that they
can always find another vulnerable machine to leap to and use as a host while
they search for new places to visit. They are like some of my relatives, you
know. The ones who believe that the world is an extended family from which they
can mooch off as long as they live.
I have a few sticky relatives like that too, you say.
Hey, dont look at me, says DeVito. I have no relatives
I can think of. At least not sticky ones.
And even more rarely, says Gene, resuming his narrative, Once
a day on average, came Net attacks that tried to subvert Passion to put it under
the control of a malicious hacker. Now these attacks came from all over the
worldmany clearly from other similarly hijacked PCs. Our pet honeypot
was attacked by a PC from a Taiwanese charity, a server in a Burmese school
and many machines in Germany.
Its a flat world out there, you say. And we are getting
flattened along with it.
