you cannot hack someone by their IP.
Well the classic way I learned 10+ years ago, is to port scan the IP, see which services are running and try (known and specific) vulnerabilities on those, brute-force (SSH etc), see if there is already a trojan running, etc. I wouldn't say it's always impossible, but generally (like basically always
) it's not gonna work. There have been a few situations though where the victim was running TeamViewer and the attacker logged in (either database leak or bruteforce) and stole their bitcoins. In theory that is in fact hacking someone with just their IP, but still not likely.
I am mostly questioning the "
new found knowledge" part. If there is truly a new method to do so (0-day vulnerability in some MS service or whatever), OP can sell it for some serious bitcoins. But yeh...
