Is it actually possible to hack into someone's computer?
    #5845146 - 07/10/06 11:42 PM (17 years, 6 months ago)

I'm not interested in actually doing this, I simply want to know if it is possible, without someone inviting you? I was talking to a kid who claims he can hack into anyone's computer, and something about that just doesn't ring true, but I've been wrong many a time. I know you can install keyloggers and whatnot, if you have physical access to the computer.

yes, but no one who could really do it would boast about it. people who hack keep that shit on the down low.

Chances are he's just accessed a couple unsecured systems before and likes to exaggerate by claiming he's teh l337 5|-|!7

In order to hack into someones computer you have to do one of a few things.

Most cases, a service is exploited with some kind of buffer overflow. A service is a program running on your computer, with a port listening on the internet. Usually these are servers who are required to have services running, because that is their job. Service examples are web servers, ftp server, ssh, etc.

As far as a normal desktop system goes, most windows machines do not have as many services running, but its not uncommon...even if you dont know about it. This is definately not "any computer" like he says though.

The next problem with personal computers lies in the fact that if you do have an open port, and it could be expoited...most broadband users have routers in place, with a shared IP. This acts as a firewall, and usually unless you specifically configure the router to forward a specific port to your computer...the outside request from the internet will be denied.

This can all change if he is on your local network, IE: Sitting outside your house, with a laptop and a wireless card.

The next method is installing some kind of trojan on your computer. Usually bundled with some kind of legit software he will send you, and when this happens...your computer is at the softwares will. Trojans will often times open a port, and let a remote computer connect. This will also pose a problem if you have a router/firewall because the port will not be open.

This does not mean that its not possible though. Some trojans are known to go to 192.168.1.1 using some default passworks like blank/admin, admin/password, etc. And changing your routers config to forward ports to you. Avoid this by changing the routers password.

New trojans are also taking this into consideration and not opening a local port for incoming connections, however repeatedly trying to connect to a specified computer. This means the attacker can have the open port, with the victim computer trying to connect to it, creating a data stream. This can work, but is often times flawed..as timing needs to be pretty accurate, and his ip cannot change, and the risk increases, etc.

All in all, he is full of shit, and just wants attention because he fails at everything else in life. If he could do it, you would know. He wouldnt have to try and convince you through AIM ;]

Almost all "real" hacking is "social hacking" rather than trying to find a weakness in the security of the hardware/software. Kevin Mitnick, for example, used social hacking to access the various networks he broke into. The rest are typically "script kiddies" that know how to run programs that look for known weaknesses on a computer network. Script kiddies usually like to brag about how "leet" they are. The movie "Hackers" idolized script kiddies, showing the world as they tend to see it, in a painful sort of way.

In answer to your question... think of a computer like a bank vault. Can you design a bank vault that cannot be broken into? Probably not. Where there is a will, there is a way. Can you design a bank vault that is so difficult to break into that nobody in their right mind would waste the time and money needed to circumvent the vault's security? Probably.

I have worked on a computer network that I am fairly certain your friend could not have hacked into. The computers were physically located in a secure area of a building that had access through a bank vault like door. The door was guarded by marines with guns 24 hours a day, 7 days a week. The entire secure area was built like a bank vault with very thick concrete walls and no openings to the outside world. The computers in the secure area were not networked to the outside. There were no phones in the secure area and cell phones and radios did not work in the area. Power lines were decoupled before entering the secure area. (In other words, there were no wires of any kind, even for power, that went through the walls from outside to inside the secure area.) Considering that none of the information we were working with in this area has ever been published, I would suspect that nobody else has ever hacked into these computers either... and this was over ten years ago. (No UFO stuff, or anything else that has a conspiracy ring to it... and I cannot talk about what we were doing, so don't ask, please.) Even a social hacker would have trouble getting info. Anybody that had access to the secure area went through a massive background check that took the CIA ten months to complete, and spent two weeks in training learning how to say "I can neither confirm nor deny..."

It basically boils down to one thing... if he was bragging, then he is probably a "leet" script kiddie, which is like a burglar that goes around looking to rob homes that the owners have left unlocked rather than a professional thief that is going to steal the Mona Lisa. The professional thief doesn't need to brag and knows better besides.

But surely someone could "hack" into the information store by, say, offering you hundred million dollars or holding a gun to your head, encouraging you to surrender the information you're privy to?

Social engineering is a powerful thing :sun:

> Social engineering is a powerful thing

Indeed, which is why "real" hackers tend to rely on it more than any other technique.

:lol: I remember reading that if the planet's surface was filled to a depth of twenty feet with computers the size of a grain of sand capable of performing calculations at the speed of light, it would take that cluster over a thousand years to break 128-bit pgp crypto. And then I remember thinking "Yeah, but how long would it take someone who investigated me to guess my current pass phrase?". All of about fifteen minutes.

people just suck, security wise :tongue:

Yep.  :smile:

PGP is very secure, given one assumption.  The huge assumption is that it is not possible to easily factor large numbers.  If somebody should discover (or publish) an easy way to factor large numbers, then PGP has no security what-so-ever.  It is a very cool proof that illustrates this.

I use 4096 bit PGP and my passphrase is almost 60 characters long, including mixed case and odd characters.  If only I had something worth while to encrypt...

:lol:

You and me both, Seuss :smirk:

I use the 4096 bit PGP encryption with a randomly-generated passphrase around 40 chars long (shit, 60? time for a new passphrase...)

Or, I should say, I'm ready to use PGP...if I ever find something worth locking up that tight :smirk:

I didn't build it, only worked in it... and it wasn't a room, but an area. It did not have all of the cool temperature and pressure gizmos that were in MI. The bank vault door was rather boring with a rather ordinary combination lock on it. Don't get excited, I'm not that good.
