Buying Used Computer Equipment For CryptoCurrency Unsafe?

[jerry0]

I know many people store their crypto in their hardware wallets.  Some store it on their computers.  Some have a computer solely for crypto to be safe.



First off, is buying anything that used for the computer unsafe if you plan to store crypto in it?  Example buying a used laptop but then doing a complete factory reset and wiping everything?  Or could a hacker still put a virus/keylog in it?



Now what about other things?  Like imagine buying a used wireless mouse or keyboard.  What about a wired mouse or keyboard?  Or maybe even a used modem or wireless router?  Is it possibly to get a virus/hack keylogged if buying anything like this used?  I thought modem/router possible because well its connecting to the internet?  Obviously something like a used monitor cannot cause anything like this right?  What about a used usb cable connecting your modem to your computer?  A used flash drive definitely for sure?  But you should never have an issue if its a new one right?



With a wired mouse or keyboard, could someone just install something inside it or something and you get keylogged etc?  What if say you left your keyboard with someone and say that person is a hacker and then install something into it.  Then when you plug it into your computer, could you get hacked?



What about a modem or router?  Could someone install something inside it where when you connect to the internet, they see everything you type etc?  Like i know hackers put out fake wifi so if say a starbucks or hotel is there, you connect to it thinking its that wifi but its actually a hacker putting the name to trick you etc.  Then you connect to it and they see all your credit card info.



Obviously you should buy things new.  But if its a modem or router or computer, if you do a factory reset, does that 100 percent wipe everything clean?  I heard of cases where people would install trojans in other people laptops without them knowing.  The person then later access their laptop or notice things got hack etc.


Thoughts on all this?  Now let just say its not for crypto but just regular email and banking and everything else.  Is buying any of these things used foolish?  Or imagine just borrowing a wireless mouse or modem from someone such as a friend or acquaintance... but their intention was they know you had crypto and put a virus on the modem or mouse.  Thoughts on this?



So could you get hacked/keylogged on


1.  Wireless Mouse or Keyboard
2.  Wired Mouse or Keyboard
3.  Modem or Router
4.  Monitor
5.  USB Flash Drive
6.  Ram




From this list, i know USB Flash Drive is 100 percent because you can store files there.  Thus if a hacker has your laptop, they could just plug the flash drive in and put a virus/keylog and then leave your computer as is and then you access it and you have no clue right?


I assume the only one in this list which is impossible would be a monitor right?


But what about a used modem or router or mouse or keyboard?  I assume wireless increases chances a lot than wired right?

Hey all related question.  So i want to buy a security camera for my apartment.  The reason is because if there are any thieves or if someone were to access my laptop and do something with it and then leave it as is and then if i use it, then i might have no idea they installed malware/trojan or anything like that.


Im going to buy a camera on amazon and i notice some reviews, they say the camera is hacked etc.  Reviews were like they heard or saw someone viewing their home or apartment with it.


Now if that is the case, does that mean they could view your keystrokes or anything you view on your laptop or anything like that?  However, if you are setting it up with only your cell phone which most of these security cameras seem to do, then thats fine?  I want to buy a security camera and point it at my door when im not there or even there but one concern is if it gets hacked, could i potentially hack my laptop or something or internet network or hack my wallet?  Or make sure you get a security camera where you dont read anything like this in the reviews.
