Topic: Buying Used Computer Equipment For CryptoCurrency Unsafe? - page 2. (Read 1043 times)
it's actually a problem where 50% of people say it's safe and only a few people say it's not safe buying a used computer for cryptocurrency, but I myself am safe now because I also use a used computer for cryptocurrency because I don't have more money to buy a new one, a little advice if you buy a used computer, you must reinstall the computer first before exploring cryptocurrency.
I have never had to buy already used computer equipment for cryptocurrency, but however, I think that the major thing here isn't whether or not the equipment is safe for use, but whether you are buying from a trusted source. If you are patronizing someone who is reliable, and has come through for you a couple of times, then there might be nothing to really worry about. Otherwise, it is unsafe.
There is a little possibility to get hacked by the hardware what you have mentioned here, According to the IT expert Wireless mouse or keyboard, Wired Mouse and Wired Keyboard are not responsible in order to be hacked, In the same way, you don't blame Monitor also because the monitor doesn't carry any storage data. I also think that Wireless equipment has more chances than wired equipment to get hacked or leaked the information what you have stored. One thing you can do that you have to use your computer fully offline when you use a used computer or related equipment. Most important thing is that you should use a private network in order to keep safe your data for being stored. There will be no chance to be stoled from your device.
Im curious about a few other products.
1. Uninterrupted Power Supply (UPS)
2. Powerbank ... imagine the ones where you buy where you can charge your laptop or tablet or phone.
Can these contain malware or not? For example whether its a used one or say a 3rd party sells it and they put it in?

What about these devices? What about a powerbank that you connect to your laptop via ac adapter?\
What if it also contains usb ports as well?
So if a powerbank has usb ports on it but you don't use it but charge your laptop with it with the ac adapter or cable they give you, such as connecting from the cable slot of power bank to the power slot of the laptop, its not possible to transfer malware?
one example but to be able to do that you have to know a lot of things, also in the movie they are using linux that's a great movie
thats why i like linux you can copy drives via terminal without being notice by others unlike windows people can definitely see it
I'm not familiar about UPS, only PSUs if that's what your talking about - realized I wasn't accurate enough in my last post so I'll break it down.
A PC has these parts
CPU
GPU
Motherboard
Ram
Storage
PSU
The storage is of biggest risk, but usually none of the other components are able to store any data in them, so it'll be impossible for malware to be installed. You can only boot into BIOS without storage, so that's why I usually wipe BIOS or flash a new one on just in case.
Power banks on the other hand, their USB ports are only made for processing power, and unless you've bought one with a wireless signal (needs to send the data back to somewhere), and USD ports that can transfer data, you'll be fine
As someone who's spent a lot of time on used hardware, and cryptocurrency, the number rule is to always assume the worst, and then prepare for that.
Assume the person who is selling you the used motherboard, or PC has infected it with malware, assume that if your BTC private key gets exposed on that PC, all is gone.
Usually the dumber hacker will install a malware on the windows account they'll set up for you, and then when your private keys touch that PC, you'll be fucked.
The best way to avoid this, use your own hard drives (I have a SSD and HDD that I install in every PC build), wipe their windows account and take their storage out - then you can wipe the mobo bios, or update it, but you should be safe with this.
Another good idea - buy a ledger, and your private keys will never be exposed to anything.

I dont exactly what are you trying to ask but there is a safe and unsafe for this
Example:
Computers that are use in mining do a lot of work during mining it stresses the processor and all parts of it
since it has to run 24x7 for like years so that parts life span is short unlike computers that are only use for browsing and so on
so its not okay to buy this equipement unless you are willing to risk money because it will not last longer
this is a no for sellers its unsafe for the seller to sell his/her harddrive why? because we can crawl and get old data from that
believe even if you format the drive it can be retrieve, and thats dangerous if you have 100 bitcoin and you save the password on the drive
My suggestion is for buyers don't buy computers that are use in mining it will not last
on seller's please don't sell computers together with hard drives remove it its not dafe

How much cost and time would it take a user to put malware in something like those 2 items i listed?
I
Well if you have to know, it is possible. If you are targeted, there is a chance to get you via social engineering: Example, I'm so nice, I'm sending you a new shiny usb keyboard! Am i not nice?
Basically anything USB could be a trojan (technically anything but lately usb is the trend). And USB with spy things can be bought in China or custom made by individuals or State organizations..
The computer used or new are about the same level of risk, assume compromised. I would use Tails or similar secure OS/distro if i were that paranoid, and it doesn't even need a hard drive (tho you could install that).
If you want to approach perfection, you would need perhaps to buy something recommended by the FSF.
Used or not, you can replace all the firmware/software of those, such as the Librem laptops.
Well if a flash drive can have, wouldn't a power bank for laptop can as well or not? What if it has 2 usb ports but you only use the charger to charge the powerbank and connect it to your laptop to charge it?
Almost all of the hardware you list doesnt have capacity to store and write data on them except the flash drive.But flashdrive with virus like a keyloger or worm viruses can easily be blocked by those anti viruses up to date.Its easy to prevent getting hacked nowadays
I keep some wallet data on the computer and it's safe. As long as I use a private network, I'm sure my data will be safe. So actually, hacking is an insecurity factor of the network used. For example we use a VPN that is less reliable, then our data could have been stolen by the owner of the VPN. So be careful when using public networks.
Unfortunately there's no fairly used Computer Equipment that's safe for cryptocurrency, or safe for any type of document generally. Many used Computer equipment are purposely hacked before there are sell out, this was my experience when i worked with Computer dealers years back, they do the hack, sell to their friends and then exploit their systems for selfish interest. Just to gain access to their privacy.
Advise: Buy fairly used Computer equipment, format the system by self or another dealer and then do the installation by self.

Are you serious? When you say these people do this, what exactly are they hacking? Like bank accounts and debit/credit cards? Or just bring noisy? Because if they hack back account, the owner can contact bank and get it back.

What you pie isn't what's unsafe, it's who you buy from. Who is the vendor, and do you trust them? If you can't trust the person who you are buying from, for some reason, then you should consider doing more research before buying.

I think op is being a little too paranoid here. I don't think there's a danger in buying used computer equipment considering as long as you know to do all the precautions there is to avoid any unwanted event. However, if we're talking about selling them (used computer equipment), it's gonna be the other way around. For selling your used computer might leave some of your data to be harvested, which some of them might be your crypto wallets. Nevertheless, it is still will not happen if you do all the precaution to erase your data before selling them.
That's the very reason why we needed to replace the hard drive when we will going to buy or sell our used computers, hard drive stored your data so this equipment always play the role so in any events replacing it will not do any damage, wise buyers and sellers will not allow this data to be recovered
so they will pay attentions and replaced this one to a new one before or after the deal has been made.
What about poker bank for laptop? What about power bank for your phone?
i think one can be fairly calm with a used computer just make a factory reset and reset the hard disk, use keyboard and mouse without flash memory, and a couple of good antivirus and it's done...
I buy many used things within reason. If they are looked after I would. I will buy the second hardware no problem at all. Cheaper and does the same thing. You will have much moeny left over since you can get it less then 50%
I buy from rich people who upgrade
I won't buy a harddrive though unless its an ssd since a nomal hdd can be worn out. I think saving a few bucks buying second-hand crypto wallet software is not worth it. Not worth the risk for so small reward.

Going for new equipment is much more better than buying used ones especially when using these equipment for cryptocurrency. Buying used computers, routers, keyboard, mouse for cryptocurrency is not a good idea! To be on a safer side, buying new equipment is very important.
I can buy any supported item,but only if it does not belong to the category of computer equipment.When it comes to tools that have some value for You it is better not to buy supported computer equipment.Crypto wallets can suffer if they are used on supported hardware.Given that cryptocurrency is gaining trend,many hackers will use different ways to steal Your passwords.
