'AITA if my USB killer fried my friend’s PC when she snooped?'

"AITA if my USB killer fried my friend’s PC when she snooped?"

I am 20F, my friend is 21F. I always carry a USB killer in my backpack. It looks like any other thumb drive except I stuck a tiny devil face sticker on it so I know it’s the dangerous one.

I keep it on me because I still live at home and my parents are super nosy; if I ever left it on my desk they’d definitely pick it up and plug it into their laptop to “see what it is.” Yesterday I had to leave campus in a rush and asked my friend to watch my bag for a bit.

I ended up not having time to come back so I just texted her to take it home and I’d grab it today. She said cool. She gets home, admits she got curious and started looking through my stuff, finds the devil sticker USB, thinks it’s my normal drive, plugs it into her gaming PC to see what files I have.

Computer instantly dies, mobo and PSU completely gone. Now she’s mad at me, saying I’m reckless for carrying something like that and I need to buy her a whole new setup, even though she knows she shouldn’t have been digging around in my bag in the first place. I feel bad her PC is dead but come on, don’t snoop and don’t plug random drives into your computer. AITA?

Here's what people had to say to OP:

Your last line covers it. She was a bad friend to look through your bag, and a bad friend to use something of yours without asking. She's learned an expensive and lifelong lesson: don't be a dick to your friends AND don't plug unknown USBs into your computer without first checking with a trusted source about what's on it. NTA.

Never ever install media of unknown content is your system. Don’t snoop in other peoples stuff. Simple rules. Violate them and bad things tend to occur.

This is known as FAFO. She snooped, she stole, she paid the price. Too bad, so sad for her.

Who in their right mind sticks an unknown USB into their PC? Do people really do this? NTA.

NTA. She acted irresponsibly and should not have snooped. BUT, depending on where you live, however, merely possessing such a device could get you charged with criminal intent and if they push it could sue you and win, because the only purpose of such a device is to cause damage.

Similar to having poisoned your food at work ("they shouldn't have eaten it") or digging a booby trap outside your bedroom ("they shouldn't have been trespassing") - neither argument flies in court and you WOULD be held liable for damages or worse.

NTA. I truly can’t imagine disrespecting a friend by invading their privacy like that. And then to have the audacity to be upset with you for what you happened to be carrying? She should’ve been apologizing for what she did and been worried about your reaction to catching her, not blaming you for what happened to her computer. Yikes, NTA but I’d recommend you rethink the friendship unfortunately.

NTA - She shouldn't have gone through your stuff, and she definitely shouldn't have taken it as far as plugging in a USB drive to see what else they can find. Interesting to see so many people saying you shouldn't have it, or why you have it - Which is frankly irrelevant to anything else and is completely your own business.
