No need to destroy and it may still be recovered from the n/w chip. Most network devices MAC ids can be spoofed.
Ignore that part... both the points were mentioned in jest. I have spoofed mac ids before. BTW, If you ever get caught on the wrong side of the law then the only person who can save your ass is ram jethmalani
I used to work from home when I was in the US in 2008. I tried to download a legal torrent related to linux and my ISP revoked my internet access within a minute. I thought my India office laptop conked off, so I started the download on US office laptop. Again, net access revoked immediately. Before I tried to do the same on my personal laptop, I realized that I might be in trouble. US ISPs didn't like torrents back then.
I tried to reason with the ISP that as they were my office's property, probably my colleague used it in my absence
. But they didn't buy that story. So, I had no option but to spoof the mac ids. Machines were working fine at home but I had a hard time explaining the IT guys why I couldn't join the LAN while in office.
If you have the time or opportunity to (securely) wipe your OS partition, then they will never be able to prove that it was your physical h/w
With some effort, the authorities can link your wiped out machine with those downloads. There are so many places where you'd have left a trace. In case of a laptop, they can contact the manufacturer for hardware details. Or checkout your invoice etc. What if you forgot to wipe your router logs? On top of that, a fresh OS install is always suspicious. And such things do happen in real world. I was once interrogated by Israeli authorities as they had some doubts about my laptop and its contents. Everything was fine... I didn't do anything wrong.
You really need to have all your bases covered to exercise "plausible deniability."
what if i use onion router like Tor for anonymous usage
What if i use a separate :LAN card
What are your intentions? Do you want to access the blocked content?
If you are a big fish then there'll be repercussions but they usually let go of small time downloaders with a warning. I don't know what happens if you are the former type... I've read about such stories only in the newspapers. They get arrested and fined etc. If you are latter, then you can expect a notice from your ISP stating when and what illegal content was downloaded from your side. They may ask you to pay a fine and expect a response. Most of the offenders choose not to respond and admit their mistake. They also stop downloading anymore illegal content - which is what the ISPs want in the first place. If the complaint is lodged by some big shots like Sony (or Avid
) then ISPs fine heavily a few offenders, to set an example for rest of the downloaders. They obviously can't run after each every downloader - so, strict action is meant for big fish only.
It's assumed that ISPs can't see your content if you are using Tor/VPN/encrypted torrent connections etc., but I believe that they can put in some effort to trace your stuff, if they think you are a big catch and worth their time & money.
