    Lightbulb Hardware Firewall issues

    Ok heres the deal, Im an A+/Network+ tech, I also teach classes at night on that and other things. I can usually figure out just about anything, but there has been one thing i cant figure out.

    It all started a few weeks ago, a client, lawyer/forensic accountant asked me to break some windows passwords and a few other things. I was able to do everything he asked, and I had a lot of fun doing it. So now this has sparked my interest. He wants to know if I can do some ethical hacking for some of his customers, and I told him id get back to him. I really want to do it, not only is it fun, but its really good money. I think im in just a little over my head Anyways back to my question.

    I can do just about anything on the networks I have been working with, thanks mostly to cain and abel and a few other tools. but thats when they give me a machine on the local network. But when the internet is in front of me, I have no idea how to get through the firewalls, software or hardware.

    Can someone point me in a good direction as to how to get the first machine. I can do anything on the customers network, but when i need to get in over the internet, im screwed.

    Thanks, any tutorials, links, or advice is greatly appreciated.

    I would start by getting their externial ip, or checking for any open wireless networks.

    Well lets just say i have thier external ip, they have actually given it to me. I run a port scan and find like 2 ports open what then, just look for exploits? what if 0 ports are open? Any tutorials or advice starting after that point?

    Thanks John

    first id like to say that mercenary hacking will land you the longest jail terms no matter whos footing the bill. that said, getting past a f/w istn't really an option. some have exploits but most fail closed which does you no good. you have to get a back-door/trojan/whatever to connect to you. depending on the type of f/w this might get pretty tricky but there a quite a few out there for any situation. pack it and morph it until it is undetected by all av systems, a process that will have to be repeated each time as new av sigs come out. then get the target to download/run it, use your social skills to find a gullable user and a good ploy. try the newest vulns ..still very likely to be un-patched on most workstations then ...well, use your imagination. now depending on the security of the network and the information your after you may or may not have to esculate privialges...you dont have to be told not to do this from home...right?

    Mercenary hacking.....I never heard of that expression before. Very good Tedob1, I'll have to remember that one.

    Ethical hacking can only be accomplished with the expressed and written consent of the owners of the network/equipment that you are attempting to hack/crack. If you are attempting to break into a system, and or network, without the knowledge and or permission of the owners.........It is not ethical and not legal. With the exception of authorized law enforcement personel with a wire tap authorization in hand.

    If your lawyer client is telling you different, than he is lying to you and setting you up for a hell of a fall. As Tedob1 has already stated, this will land you the hardest and longest jail terms, even longer than hacking to steal money.

    you like that moxnix?....it's yours

    BTW what two ports show open? if one a web server that might be a whole different ball game! and use nmap to determin the fw type so you know what your dealing with.

    Sounds wrong way round to me.................I would expect to check and harden the system from the inside FIRST before testing it for hackability?

    just a thought

    Ok so heres where im at, he gave me his external ip (made him goto ipchicken.com) and for kicks he says, he gave me his home ip as well. I had him draw up a document that says he gave me permission to attempt anything i want. Its kinda ruff around the edges, but he also made it reusable for me incase i get good at this.

    Anyways, ive been doing a whole hell of a lot of reading, I have a good amount of intrest in this and theres good money so why not lol

    So now, i used NetTools3 to run a port scan on the both machines. i have found that the only port open on them is the pop3 110. Im not really sure whats next. I tried messing around with a whole heep of apps from the astalavista cd, that didnt really get me anywhere, also I have been checking out the Learnkey Hacking Revealed cds.

    Anyways I appreciate all the help so far, and if you dont mind a little hand holding, whats next?

    ps the home machine is xp pro running norton firewall(i always here its crap, i dont use symantec anything on customers machines) and the work machine is behind a home grade linksys router.
