USB
So we were 5 guys playing on the computer together one night and I went out for a second when I came back my friend had plugged an USB into my computer but I didn't noticed. By the time pictures and statuses came up on my Facebook and Instagram taken and wrote from his computer. What did that USB do to my PC? Like how did he got control over my computer? Did he overwatched it?

Thanks. We'll let you know when a new response is added.

Most likely the USB drive was a keyboard logger that can capture your key strokes (passwords and all).

    Have you asked your friend this same Q ! If not, why and if you left this computer (I think laptop) at risk, then why are you not asking your friend ! It seems that, probably, your friend activated remote control mechanism on your computer or some kind of software that can control this from remote method. Check if there is/ are any kind of unwanted software(s) installed there. Or if you are not so comfortable, call an expert to overcome this issue.

    I removed the usb and he couldn't control anything anymore, so yes there must be some kind of remote software on the usb, but no software installed on the computer, asked him and he wouldn't tell me how, but the usb was a special specific brand that i looked up, something with recording medicin for patients or something like that :I

    He may have installed a key-logger and now has a file of everything you type. This includes accounts, passwords, credit card numbers basically anything you type goes into a file and he can then have it sent via e-mail without your knowledge. Run a virus scan immediately. How well do you trust this friend?

    He may have installed the key logger from the USB drive while you stepped out and he did not have a chance to remove it before you came back. These programs are usually very small ans install in seconds. After running you virus scan, or from a clean computer, change all you passwords.

    Let this be a good lesson to others - and to spread the word to their users - to get into the habit of locking their screens and disabling Auto-run/AutoPlay in Windows. I think a fair amount of breaches could be prevented by these two actions.

    There are several possibilities here. One was that there was trojan running on the USB Drive, and that uploaded all the data from the USB to your other accounts. All of my systems are set to auto scan for virus / malware upon insertion of any sort of memory devices to prevent being attacked this way. There is another possibility here too. This issue is something that showed up on Sophos recently in that Facebook and Social Network sites are now set to scan for pictures and other media that may be on memory devices, and if you do not have settings in your account set correctly, to prevent this, it will automatically load any media that is on the memory device to your social networking site. That is one of the main reasons that I do not allow my system to say logged into social media sites. even when I am not in them. I do not store my passwords. And lastly I make sure that my security settings on the social networking site is set to not allow this, but I don't trust it this anyway, and I am always checking. I got burned by Microsoft on this level because someone at Microsoft granted access to my Windows account without my permission. Once you are in on one level, you may other subordinate accounts below it that every now has access to it.
