Victim of pishing in MtGox

[mineriapepe]

Hello. Lamentably I was a victim of pishing from Mtgix.tk. , asking me for a MtGox verification. All my funds are gone. I send a mail to MtGox to abort the transactions. Do it work???

Thanks.

Bitcoin transactions cannot be aborted.

You clicked the link...  

The site is was not very accurate, was missing the CA...,

You can, I guess, fill out a ticket and see... but I doubt it.

Use the real site http://support.mtgox.com  this time.

Sorry to here it.

Thanks, I send the tickets already in the correct place

The green dot of the start of .tk domains, confused me.

I received this phishing email in the last 24 hours (my email was on the original leaked list - surprised that they took this long to get around to it), forwarded it to Mt.Gox

Hello Redacted,

Thank you, this is indeed a phishing attempt. We will never send you an email asking you to log in anywhere, although we may occasionally send emails pointing you to the support page for information updates.

The email you provided has been documented, and will be used in our efforts to prevent phishers from continuing to target our users.

Kind regards,

I have wondered why Mt. Gox doesn't implement an optional irrevocable timer.

User sets a 1 hour to 48 hour delay timer.  Once set this timer can't be removed or reduced without waiting timeout period.

1) User (or attacker makes withdraw attempt)
2) User email (and possible SMS) is notified.
3) Timer engages.  If user set a 24 hour delay then funds will transfer in 24 hours.
4) If transfer is valid then user does nothing and in 24 hours funds will transfer.
5) If transfer if bogus then user aborts the transfer.

Making other "high security" changes would also require notification and delay timer period.
* changing email address
* adding new bank account for wire transfers


Yeah it would be less convenient is user wants to move funds rapidly but it would be user optional.  Users can each choose the compromise between security and convenience.

I think put some private "welcome message" hilighted -- like LibertyReserve does -- would somehow help.

Thats a damn good idea, you would save so much money from being stolen!

I was at 7-11 yesterday.  They have those time lock safes and it made me think of it.

Hopefully Mt. Gox understands that layered security is the only real security.  Personally I always look for the Green Address but some people don't.

Green Address
yubikey
strong password requirement
encrypted hashed password table (w/ key hardening)
user education
time locks
etc

all together created a layered defense.

encrypted password list

If you're referring to how passwords are stored server-side, then it should be hashed, not encrypted (huge difference).  Also, they should be salted and hashed with something like bcrypt with performs key hardening, not a hash primitive like sha256.

Yeah I was thinking that just wrote encryption for some reason.  Updated.

I wonder how many BTC's they stole total that day?

I also got the same mail, stating that my account is under review.
I was shocked for a moment, since after much struggle I was able to get Verified status.
When I clicked the link, it asked for username and password, resembling the same new mtgox interface.
Then I noticed the last price, which was some $3.xx, which alarmed me, since I had seen the price at 4.6x some 5-10 minutes ago.
After that I noticed the URL and then I was sure this is phishing

[Edward50]

I just got this same phishing E-mail about acounts being verified today.
It looked pretty legit also. But I knew right away it was wierd.




How the hell did they get my E-Mail address to send me this letter?

[Otoh]

assume that your email address wasn't on the original Mt.Gox leaked list or you wouldn't have asked such an obvious question, personally in your case I'd be inclined to suspect Goldilocks on this one
