Hi there. Is Metamask included with this kind of viruses.
I just did it recently and now I have read about this thread of yours.

Dont really know a deep information about this extensions.
All I know is Metamask is being prioritize since it had been the easier method.
Am I still in a safe journey now? All my Ethereum and other coins is there and I dont want it to be in jeopardy.

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

I have used some browser extension but not really trusted them much just as I don't know how they are getting data from us. Just as how google collected our data.

I have heard some spyware and probably this kind of extension that automatically change the address when you are about to send some coins into the scammer's address. If you didn't put enough attention it could easily steal your money away from you.

Maybe you just need a specific and secured browser if you want to use online wallet and keep mantaining your PC if you use desktop wallet.

Browser extension like metamask is needed by users who wants to work on ethlance. Such wallet works for people who got use to it quickly and they also store their money there from the Jobs they took. The importnat thing to do just when you user browser extension is I guess to download the extension from the team's website itself where they give out the link to their products.

I think anything that we download from internet, usually must be careful with it. I am in computer that only for crypto never download anything except picture for avatar in signature campaign. I think for now anything can be platform for malware or any kind like that to infect our computer. That is why i do like that when i get paid from signature campaign, i spare money to save and buy computer only to open wallet.

If extensions are scammy then it will be just the same as visiting scam website directly and telling the scam to come and steal our fund or we give them the right to install spy ware on our laptop that will make the scammer be able to monitor our cryptocurrency account and then steal our fund.

We really need to be very careful of the extension that we install, not all extension are actually bad, we just have to make sure that we follow extension from companies that are very reliable and not just the ones that we see verified, because even the verified ones will never tell the story that they have such thing, because it is very difficult to trace an extension to malware, so the only way to avoid it is either we don’t install the software at all or we extremely ensure that the company is a reliable one.

Its been a long time since ive knew that browser extensions are bad news and in fact they should consider red flags, you can easily get viruses on your pc or even spyware but the latest news about these so called browser extensions is they can be used to steal your coins, consider this a warning for those who use chrome and mozilla firefox browser extensions regularly. I came across the warning while surfing the internet today.

Browser extensions can help scammers steal your crypto Casa CEO Jeremy Welch warned the audience at the Baltic Honeybadger conference in Riga this weekend.

Sorry i couldn't drop link to the full news because i got the warning news from pivot news which would require you to download app before reading any news, share this warning with friends and crypto fans especially newbies
I never read and heard it before. Anyway thanks for this article it is very helpful and now for sure many people are aware in this threat that's why I always prefer to use ledger wallet.

Browser extensions can only steal browsing cache and data but i haven't seen whereby browser plugin spreading malware and virus, although nothing is impossible, the wallets that are in high risk to browser plugins are online web wallets and metamask plugin extension since they store data in browser data space

I've been using some browser extensions for my work and so far they are good for me, as long as the extension is verified and had a good reviews and those extensions have proven to be safe, some of the extensions I'm using is the Alexa and download manager.

Bit if you are downloading browser extensions from a third party then you better check it twice or thrice this is where hackers find their way to hack your wallet.

I heard this browser extension news. I stopped using browser extension before this i used in chrome extension. If browser has low support by user than shouldn't use browser extension. First support for extension software is Mozilla Firefox in 2004.

Just use as few browsers or outside applications as possible and you should be fine. Ideally you aren't using Chrome at all and you're using another browser, but if you must, just keep extensions like uBlock Origin and nothing extra or extensions with very low download counts in case there's malicious code hidden inside. You do gain convenience from using browser extensions to simplify things from automatically refreshing a page to autofilling, but you're also sacrificing security by doing so, and in many cases that's worth much more than the time you save with those extensions.

And that's why I do not use this extensions despite the fact that it has its inherent advantages, but they cannot be compared with the risk that's coming into play when you actually use them.

I'm one of those bitcoin enthusiast who's too concerned about security and safety, and I think it's a good thing to do, it has aided me so well that I've not fallen for any scam since I started operating on the network, any thing such as extensions that has a tendency to make me lose my bitcoins, I do not use, and if I do, I make sure they are the legit ones and also use all preventive measures available, everyone should indeed act that way.

If browser extensions can steal bitcoin, that means they've got some level of privacy infringement. Obviously, it's extensions from scammers which are mainly unofficial. This doesn't apply to web3 extensions like metamask so that shouldn't be a generalised statement. Aside browser extensions, some malicious keyboards can steal your private keys or mnemonic phrases. So my advise is, do not install 3rd party keyboards at all.

Fake Metamask extension is widely used for phishing the crypto customers but there are other ways of scamming people. The fake wallets are the requirements for the crypto bounty programs and the same working principle is actual for the fraud browser extensions. Before downloading the third-party software especially the browser extensions, checking the source from the site is a good idea for not becoming a next victim of the scammers.

I also use the Brave and Chrome browser on the both personal computer and notebook. The security of the crypto wallets is my primary anxiety however, the fake applications can leak the data from the personal computer. After downloading the third-party sofware I look for the additional information like feedback by other users, the rating of the extension. If the extension has rated over 3 stars and the count of feedbacks exceed the 10k, I will not think again to check the trustworthiness of the extension.

Any extension can read what you do and send on the internet. And some are used to debug a webpage... That's mean they can read all what you type and what website you are surfing on.
They are all potential threat to steal your passwords, private keys and information if the developers of thoses extensions decide to recover all the datas.
That's why an extension should only be activate when necessary.

The simply truth is, one has to be very careful with the extensions they download to their systems. This is because, extensions could easily be spywares and malwares developed by scammers to take hold of your information and report back to them to enable them still sensitive information with the sole purpose of defrauding innocent people. It is very possible to hear people cry of login details being compromised, this is one of the ways in which important information can be stolen and theft carried out.

I have never heard about Bitcoin stealing, with a browser extension, but Yes, I have heard several browser extension, chrome, in this case, can hack into your MetaMask account and then send all of your assets (not only ETH) but all the asset in your MetaMask wallet. This happened year ago, so I think it has been fixed. So, it is not impossible that someone tries to steal your bitcoin using browsing extension. My advice would be, never use a browser wallet, or else never install any 3rd party browser extension.

There is a possibility that could happen because it installed third-party applications in your browser. More careful to access your wallet and keep the private key always safe.
To be completely safe you need to use only safety programs. In no case do not install applications from untrusted manufacturers. Before installing each program, it is necessary to verify the checksum. The only way you protect yourself from fraudsters using the modified program.

I have read an article and experienced by my own friend because installing some extensions in their browser, the extension owner can be used to steal passwords owned by the computer owner, it's better when you have to be careful when you want to install extensions.
