cant you just install a keylogger remotely? or send a packet or whatever for them to download? or run a scavenger hunt password thing and find a password and go to a commonly used website that requires the storage of your social like an online banking account?
btw, this thread is about to hit the 4 page mark, yall should be embarassed...
Who is going to make distracted rip thread?
The most common way to install a trojan is to patch a self-extracting archive or an installer inside a popular torrent. But this gets you random victims. To target someone, you need their IP address. I went into how you can find a persons IP address if you know the websites they visit (RCF). You can also learn a persons IP if you are geographically
or topologically (network-wise) located near them, and they are on a cable network.
Anyway, with the target IP, you can either push exploits directly to their system remotely (assuming they have some running services, even Google Talk is an exploitable service; don't just think of the standard TCP services like FTP/SSH etc). Most people would use the metasploit framework for this; but if you're savvy, you'll go on IRC and probably trade up for something closer to 0-day exploits.
Again, you can also perform a man in the middle attack over the HFC network (again, this can't be done over DSL, but there would be other approaches)...
Point being, you search for multiple vectors of attack on the IP by information gathering. What kind of router? Is it updated? No? Can I remote exploit? What kind of modem? Broadcomm (Motorola)? SB5xxx (excluding 5101a) and below can be remotely exploited via their noisy bootloader.. Running any services? Instant messengers are great targets.. How close am I to the target, or is there an exploitable target near them? Bluetooth receiver on the laptop/desktop? WIDCOMM drivers are notoriously exploitable and give a pivot from the kernel off-top in 32-bit systems.
Point being... Most setups can get exploited because they're misconfigured or are too trusting of third party software/Microsoft.
