How can I know if someone copied my files in my USB to their computer?
You could check the last time the files were accessed, but that will probably just tell you when he inserted the USB stick and the computer scanned the contents. It will not tell you either way whether he copied them or not.I think you need a reality check. If you give someone a USB stick containing private or secret files then its your own fault if that person accessed them.No you don't have a right to search their computer for the file. You could ask your friend about the files, but this might just make things worse, especially if he simply copied the files and doesn't know yet exactly what the files are.If you dont want files to be accessed by someone then dont give them a folder full of them. If you absolutely have to, then you can encrypt the files. If you cannot do that then dont store them on a USB stick that you give out to your friends.Chalk this one up to experience and think carefully the next time you need to share files. Have you ever heard of email … or the cloud? Just a thought

How can someone hack your phone through the IMEI number?
IMHO the IMEI is a device identifier (International Mobile Station Equipment Identity). You can retrieve it from any device by dialling *#06#. So it´s not a real secret, and anyone borrowing your phone for a short moment can get hold of it. The IMEI is bound to the device, not your phone number or account. It could be used to track stolen phones, and to lock them out from networks (done in a few countries, but not across borders or carriers normally, they could not agree on a global DB). However, some phones apparently allow changing the IMEI, which is of course a bad idea (why hardware vendors allow such things BTW, is it too hard to burn in a number of bytes and then make them read-only?) and people could overwrite it easily.If WhatsApp would use the IMEI for personal identity I could not change my phone anymore, if my old one breaks. The whole idea of GSM was and is that you are not bound to the phone, rather you are just bound to the SIM card, and that is what needs to be protected. The SIM is your key to your telephone number, that´s the reason why you got a PIN code and why it locks you out after 3 failed attempts.There isn't any identity theft possible by knowing telephone number and IMEI. You need to get hold of the SIM card, somehow hack it and retrieve the IMSI. This is what identifies you against the mobile provider.
If I am using someones's wifi hotspot, are my files protected or can they view/copy files/notes on my phone?
hacking someone on the same wifi is very easy, it is called MITM (man in the middle).an attacker can sniff your packets, redirect you to fake or malicious websites,steal your cookies to hijack your session. This attack is dangerous and might lead to a full device control,if the hacker knows how to use the android/windows exploit kits (kits that download trojans silently), or how to use a RAT(remote administration tool) or a botnet.so basically your device might get completely hacked if the hacker has some knowledge about the points above.edit: and I disagree with the previous answers, I can steal your credentials even if you’re on an HTTPS website (SSL), this is called “Form-Grabbing”
