Okay I've downloaded the wallet from the website and it still says zero connections plus all my OPAL right now are on Bittrex but bittrex has OPAL disabled? Does this mean I'm gonna lose my coins? Or will I  still have them?

True, however the most important thing is: Don't keep your wallet encryption passwords anywhere near your PC. Even if a hacker was able to steal your wallet.dat file, he cannot grab the coins if he doesnt have the password. Ive heard about a program called keyscrambler, what it does is basically hide everything that you type. Keyloggers won't work for the hacker. Which is pretty important, incase you want to unlock your wallet for staking for example.

The motive was to steal your coins and convert them to btc and then fiat.  There have been numerous attempts recently to hijack users computers with infected wallets.  Those were typically done with a new coin launch but it appears that they have switched tactics since people have become wise to the Windows wallet only ninja launches that idiots would jump on and run the infected wallet.

Opal was likely just chosen at random.  This should be a warning to all that you never run a wallet posted by anyone but the official representatives for that coin.

This is likely to be repeated with other coins because there is never a shortage of idiots out there and these scumbags know that.  Make sure that you don't just update wallets because it's posted in a thread.  Make sure that the person posting it is legitimate.  

why cryptsy not freezed?

Alright, so what's the next move? Are we waiting on an OPAL client update for the rollback?

There was no attack on Opal. Scam_exposer is right, just user funds that have been taken. Sad enough though.

I use the term "attacker" rather than "hacker". In my mind, the actions of an attacker is an attack.

And if the motive behind the attack was to harm OPAL, it was magnificently successful.

OK. Decision made. Timescales??

This wasn't an attack.  It was users installing a backdoor on their computer allowing their wallet files to be taken.  

This has nothing to do with Opal the coin but restoring coins to users that did not protect their computers.  Rolling back the blockchain for user incompetence is idiotic.  



  

Yes

Ok, thanks StonerStanley, So during the corruption, the backdoor/the attacker can't install other malware/exploit ?


if yes my only advice (for corrupted wallets) will be "CHANGE ALL YOUR PASSWORDS".

Probably not, I believe I read it was some normal maintence

No you won't.

Does this mean I'll lose the OPALCoins that I have on the Bittrex exchange? That's the only place I have some right now and wanted to know if I would still have them
?

OPAL trading was halted several days ago on Poloniex; was that related to this attack?

well iam alsowating for the same but no updates on trading.

I fully support the rollback. If anyone can make this work, is the Opal dev's and community.

People, please scan your computers fully before the rollback takes place.

We have to design a procedure where someone's wallet.dat was stolen and it was not protected with a passphrase.  If we roll back, doesn't the hacker still have the privkeys to the addresses stored in the wallet.dat?

Let's do this patiently and methodically.

any chance bittrex can resume trading in the meantime and maybe just keep deposits and withdrawals frozen? how long can we expect to resume trading? i have btc stuck in orders on bittrex i could use to generate profits elsewhere in the meantime.

"malwares bytes detects the malware as "Backdoor.Agent.SBFGen"


This Backdoor or another affiliated agent may reload itself after a remove

Steps to clean your desktop:

Download Malwarebytes. (go to www.malwarebytes.org check your url field has exactly this url)
while installing, uncheck the "i want to use for free Malwarebytes premium for x days...)
Double click and update it.

Reboot with safe mode choose the simple Safe mode (Without NETWORKING)
if you used USB drive while being infected, plug the USB and start a complete scan
Fix all entries (PUP/Malware/Trojan/backdoor...) except maybe your miner software cgminer/sgminer

for those who were infected AND after the remove/reboot from Malwarebytes (under the safe mode):
check if Malwarebytes re-detect it or not (Re-scan)

if yes, you could try combofix, reboot (normal mode) Download it from bleepingcomputer
Save it to your desktop.

Note: Windows 8.1 and Windows 2000 are NOT supported by ComboFix
(i.E: XP, Vista, Seven and windows 8 is supported)

If you store files here:
-Temporary Internet Files
-Temp Folder
-Windows Recycle Bin
and want to keep it, move them to a safer location before the combofix scan. (remember to replace them after the scan)

You MUST close all open Windows.
Turn off Antivirii, antimalware residents, windows update, java update... other runnning programs.
(remember to turn them on after the scan)

Run Combofix, Please note: Be Patient, dont touch your computer untill been asked by combofix, possibly for:
-the installation of the windows recovery console (click yes)
-the scan (Click 'Yes' to continue scanning for malware...)

Combofix will disconnect your computer from the Internet and it will change your clock format (after the scan it will restore them.)
You will see around 35 to 50 stages, be patient.

The Find3M windows will stay a long time, Again, Be patient.

Then a new screen appear telling you the combofix report, will be located at C:\ComboFix.txt
usefull if you want to have further analyse, you can post this log in the dedicated forum of bleepingcomputer, majorgeeks, Malwareremoval.com

When you are sure your PC is clean, you can uninstall Combofix:
For Vista/seven/8: In the Search field, type Combofix /uninstall
(type a space between "Combofix" and "/uninstall") then press enter.

For XP: click start then Run, in the Run field, type Combofix /uninstall
(type a space between "Combofix" and "/uninstall") then press enter.

Reboot (safe mode) and run a Malwarebytes full scan. You should have wipe the backdoor and any other dangerous hack.
At this point YOU MUST CHANGE ALL YOUR PASSWORDS.

hope it helps

Im still behind Opalcoin aswell. I understand this is a very hard choice for the opal team. Best of luck!
