This isnt surprising since most trojans were made in order to mine bitcoins using cpu and gpu devices, but with the difficulty on this level, even a botnet with thousands of computers
cant make enough profit to the attacker. Also before there were alot of wallet stealing trojans that had to do simple task, locate wallet.dat and upload it to attacker, but even wallets are much more secure now.
Bitcoin simply isnt as profitable for attackers as it used to be, so they moved elsewhere.
There now are stories like this one from Verge, which is much more troubling : http://www.theverge.com/a/anatomy-of-a-hack [worth reading]

cheers

Thanks for the article, it's really scary stuff.

A new report from security firm Symantec claims the number of Trojan malware programs targeting bitcoin users has fallen in the past year. they suggest that since the number of users of crypto is still low it is not a good target!

it is a good news but i thought cryptocurrency was getting popular so as a result it will attract evil people too but seems not!

It might also have something to do with Bitcoin's price?
The bitcoins that the trojans gain fetch far less fiat these days.

Password protect your wallet. Or save your coins on some trusted exchanger site.
Also, do not disable your antivirus, just update it and be safer.
I said this about antivirus as many users doing it "because it slows down their CPU" or whatever reason is.
Just don't. Stay protected. I know that sometime virus or trojan is undetected by antivirus, but it's more chances to not get infected by keeping antivirus up and running updates every day. Also, Malwarebytes is a good protection, can work with antivirus without conflict.

Im considering moving to Linux for this reason and forget about updating antiviruses and whatnot.

If u use multisig, trojan cant do anything as one private key wont give them the bitcoin...

Some users are plain lazy and just sign them all on one. Also, it is possible for malware to spread via a usb storage device. If this happens, the other keys could probably be compromised.

Having lower number of malware programs doesn't mean anything. I bet there are still users losing their coins either due to carelessness, ignorance or for whatever reasons and most of the time it sounds easier than it seems. And there were cases of coins getting stolen having nothing to do with malware, it was just left over there for the taking.

probably we blame too much to the bitcoin users who hasn't implemented security method to protect their bitcoin and end up losing them! It may be the reasons the masses still stay far away from bitçoin. Bitcoin itself needs to be unbreakable like the banks vaults and user friendly. The masses will be comfortable to use it.

Since Bitcoin is decentralized, we can't expect someone to take control of your coins and keep it secure for you. It's your coins and you need to take responsibility for it. Malware threat can possibly never be eliminated in our real life world. The best way is to practice security measures. It is very easy for one to reduce the risk of being infected with virus on an everyday computer :"Don't download foreign programs".

Not only trojan but silent miners! That makes 99x PROFIT! Satoshi wont be happy with that Sad

If satoshi's computer got infected...its over...hacker will probably take over Bitcoin Embarrassed

Okay so much FUD, No Satoshi was smart, very smart and if you think he left all of his private keys unencrypted on his harddrive and keeps it just connected to the internet after knowing what a risk it is you are dumb. Satoshi has probably deleted his coins anyway or he's dead.

ofcourse it is possible with present security because owr antiviruses are not fully designed to stop these type of attack

Password protect your wallet. Or save your coins on some trusted exchanger site.

This is horrible advice. Offline storage is the best option.

Never save your coins online with any service or exchange. And if you do make sure you store a very little amount in wallet sites.

People just need to stop with downloading and installing crap because it says "100% working Bitcoin generator!"

I'm pretty sure he is safetly storing his btc.. He is not an idiot, come on guys.

He might be an idiot Tongue

. Human make always makes mistakes.If he didnt do mistake , he aint human Roll Eyes

There is a difference between making a mistake and being an idiot. I expect he can manage to store at least some of his bitcoins in a paper wallet that is obviously completely safe from trojans.
I use online wallets generally with 2FA and strong unique passwords, and I am not quite as tech savvy as Satoshi!

It does seem that trojans like these will be a hinderance to further adoption of bitcoin though, your average windows 7, internet explorer user won't use Bitcoin again if they manage to lose them without doing anthing really wrong.

I'm curious, why on earth is a New Password requirement not part of the installation setup for every wallet in existence? I would think it should be automatic that whenever you install a wallet that it asks you to set up a password the first time you run it. The thought that people are downloading wallets and sending BTC to them and not realizing that anyone/anything accessing their PC can simply take the bitcoins, floors me.

I think most wallets first prompt the user to create a password to encrypt the wallet with when it's first generated. I know Electrum does, and Trezor recommends that the user either enters a PIN, or a password. I'm not sure why wallets like Mycellium, or Bitcoin-Core don't recommend setting a password when the wallet is first created.

that's the bad side of this, if you are not careful you can have your bitcoin stolen, as it is something you have in your computer and it is untraceable, hackers have bitcoin users as a target

Silent miners do not profit as much as before. To gain a viable hashrate, you need thousands of the most powerful and biggest hardware. GPU or CPU mining is dead long ago compared to ASIC.

The saving coins method is flawed. Everyone said inputs.io was legit and looked what happen Angry

. True it's a wallet service but exchanges are all the same. If you password protect the wallet, the password can still be captured if you have a virus.

Most Bitcoin users use Ubuntu which do not have much vulnerability.
