Be Careful Sharing The QR Code Of Your Wallet Too

[martina14]

If you are a type of gullible individuals here in crypto space, certainly, you are closed to become a victim by the scammer
for sure. That is why my rule is never talk to a stranger unless you know him anyhow. And never forget that Qr code,
seed phrase or private key is the most important matter here in cryptocurrency business industry

I never thought that such troubles could arise because of the QR code of my wallet. I constantly use the METAMASK application and this information is very important to me. Thanks to the author.

For your safety , when making use of a cryptocurrency wallet, you don’t have to be sharing any information at all with people you don’t know. Everything that has to do with your cryptocurrency wallet should be secured, every single bit of information. Even the slightest information that you least expect can be used to track or hack your wallet and before you know it you have lost your assets that are stored in there.

So, when giving out information just make sure that you’re giving out the ones you’re meant to give out and not the ones you are not to. It’s just like people who drop their emails online thinking that there is no risk in doing that, that can be a risk because anyone can hack your email and look through it and be able to lay hands on information that are very important to you. So, let’s always be guided.

A bit such incident happened with me. I store my 2fa QR code image in my email and somehow it’s stolen by hacker even though at first i didn’t found any clue how it happened than i observed it’s leaked from my QR code. Thanks for your post to alerting in here.

You have heard about never share your private key or recovery phrase but sharing qr codes is as dangerous.

There is sync with mobile feature in metamask wallet which lets you sync your desktop metamask with mobile, problem is it gives complete access to the one scanning qr, which many are unaware of.

Always verify who you receive dms from, all these scams started from fake dms then proceeded to MM qr code.

Edit: metamask has disabled the qr code feature as of now.

With the way the crypto space is growing and the push for scammers to get to their victims in any way they can, I would say it's better not to share any information other than wallet addresses with anyone or even store it on your frequently used device, offline is always best . Also, better to just share the wallet address but anything short of that, just keep it to yourself, the reason being, I used to know you could scan a QR code instead of sending an address but with this new development, let someone not get mixed up, then just a better wallet address to share.

This is why I don’t sent any details on email because it can compromise and its too risky. Hackers has a lot of ways to hack people, sharing QR code of your address might also be risky, better not to try it at all. Store all your important information online, this could save you a lot from any trouble especially now the market is getting better so you might want to be safe.

Actually we had better store all our passwords and keys vice versa off-line, on paper in the place where nobody has access to. If you store it somewhere in your computer, a hacker can send you a letter with virus for example, and this way your computer will be hacked and all information will be stolen. So personally I have put all my keys in my notebook.

Yes, I believe QR codes infected with malware constitute a new concern. When you scan the code, a malicious code will record information about your wallet which can be used to commit fraud. Scanning should be done with care.

This mistaken was a few years back when i was newbie in bitcointalk. I learned from this incident now again i will never do this shit. My all of wallet secret phrase stored in offline, nothing 100% safe in online though i am using internet security to protect my computer from unexpected things.

It seems we are missing a point here.
The QR code which was shared by the user was associated with his private keys.

#3 Tweet specify the exact communication of NFT guy with the fake mod. They clearly mentions that it was private key which got shared by mistake. I am pretty sure there is low chance that the tech will be able to extract the private keys from the public key. This way not only MetaMask but the whole other wallets will be compromised / should have been compromised by this time as they use the same synchronisation protocol.

It's really a good share btw because everyone should have their eyes wide open before sharing their qr codes. Good insane tip is to keep both of them separate and only keep the public keys handy while sharing.

Usually QR also has data for access to our wallet. Even if we open Myetherwallet there to get the private key. We will also be shown with a QR code. We need to be more careful to store our wallet access. Accessing a QR account is required.

Oh, wow that's anew one. I honestly didn't know that. And looking critically at it, its a huge security breach. I just checked my mobile Metamask, and truly, they have disabled that share option. So kudos mate, for bringing this up. By the way, many malicious actors would hate your guts for this

Wow, I never realized this myself if it turns out that fraudsters have been able to create fake QR codes that can scan all the information of other people who scan their codes, this is really scary because fake QR codes and real ones are indistinguishable.

Thanks so much for the advice. This world is an advance place due to technology advancement, small mistakes will lead to a very huge lost, most especially wallets keys that give access to all token and assets in the wallet, once some scammers were able to access your key all tokens were gone. This is a very good advice I hope newbies like me will take note of this.

Criminals are getting smarter and we need to be one step ahead of them, no matter how difficult it is. I have always been told never to give my private key or seed phrase to others, but now people scam by spreading seed phrases, it's so stupid and greedy for what they do. You will lose all your money in return, never trust a project or a website that forces you to enter 12 keys and understand it is just a scam and we need to be alert.

It is always a must not to share your private keys or even QR codes because in this digital age, scammers are even smarter than us. They will always find ways to scam other people because its their job that sustain their daily living. Everything that seems so suspicious should not be tolerated and as much as possible, never entertain people or websites that are almost indulging your privacy. I thought only private keys can get steal, but now also QR codes. This is the reason why we should always stay alert and cautious.
