Can someone hack an encrypted wallet.dat?

[Amph]

remember that if you're device is infected, by the time you type your password on that device, it does not matter how strong the password was, it's like giving it to the hacker

Good paid antivirus, antikeylogger and antimalware software should protect you.

In addition to at least 15 letters passwords, combination letters and symbols.

short of having a keylogger on your system

this website will give you a good clue as to how strong your password is.

use a sentence as your password

"thereoncewasnoblocklimit"

would take "7 QUADRILLION YEARS" to brute force

Do Wallet-qt files have keyloggers in general?

[LiteCoinGuy]

i used 35 random letters - maybe iam too paranoid   ?


or buy a hardware wallet which even functions on an infected pc.



@cryptoheadd

There has been loads of studies done to show that paid vs free antivirus makes no differance at all, apart from the frills around the edges on the paid versions which are designed for aunt sally who uses a computer and was convinced by the 20 year old sales rep selling her the computer that she had to have it or her whole computer would blow up the minute it was turned on.....lol    cha ching $$$$$$$

Thank you all for your help.

Hey,

I was just wondering, is it possible for someone to hack an encrypted wallet.dat

Thanks

As other said. The only factor here is method of encryption and strength of your password. There are method of encrypting your files with algorithms that are impossible to break at this moment.
I recently got attacked by CryptoWall virus, and this Trojan encrypted every file on my disk with SHA256 algorithm. This is impossible to brute force now. Maybe in the future.

i have read about that trojan, it sounds like some scary ransomeware!

do you know how you got infected by it , i want to know how to prevent.

I personally know two guys that got infected by opening email attachments... A rule of thumb would be to never open attachments from people you don't know, but evidence suggests not everybody has enough basic knowledge to stay away from such emails.

The infection was not on my PC but  instead on my mom's notebook (where I keep handful of my own files and copy of some crucial projects).
And in my case it wasn't anything than came with an email. I think is was some fake update installer like flash, java or something like that.
interesting fact that laptop was protected by antivirus and ransomware wasn't detected - in the end I got rid of it by using Malwarebytes Anti-Malware.
