Copyright Infringement

Torrents?

What's your country?

What medium was the notice sent through? Email? Mail? Registered mail?

Who sent the notice? Provider? Law firm? Some guy?

Are they naming a particular work that you supposedly infringed upon?

Does it list a specific IP address? Is the IP address tied to you?

Spam?

I got letter from my provider in which they accused me of downloading illegal content.
It had a list of some movies I downloaded. I believe one of them was for Into the Wild.
This was years ago. Downloading is still not forbidden in my country but the provider had the task to notify me.

Who sent the letter? Your question is missing some vital info.

Sound like standart email forwarded by isp. if not - it might be just copyright troll.

It could be a spoof e-mail that looks real, but is actually fake. If you have not actually downloaded any of the stuff they said and no one in your house has either, contact your ISP, though not with any numbers that would be on the e-mail. Find out from them whats going on and if its a spoof e-mail or not. If its not, you might have someone accessing your internet connection some how.

ISPs will not email. They will send it via physical mail to establish a paper trail should a suit ever arise. In addition, they will explicitly name the item(s) you have supposedly acquired illicitly. If this has come via email, it is a fake.

maybe just analog scam ?

if its not on paper it is most likely fake. it is pretty easy to send an email with any sender address you want.

this was funny for pranks in school 15 years ago ;) - but nowadays its just annoying because of spam and scams.

• check if you actually did something they claim

• check computer for viruses and malware (perhaps it was/is part of a botnet)

• if they want money, check who/how they want it -> if it smells (paysafecard etc): fake
