Got an email from an, info@btcguild.com with a subject of, "invoice".  I assume this is a phishing email trying to get you to open the attachment, DON"T OPEN IT if you get an email like this.

I am sure Eleuthria can comment further, just wanted to bring it to everyone's attention.

BTC Guild does not send any unsolicited emails.  The only automated emails you will receive from the pool are confirmations for wallet/email address changes, or idle miner alerts.  If you get a wallet/email change email, you should  not click any links in that email unless you actually requested it (though you should check if its legit, because if it is it means somebody has your username+password).

There have been many phishing email scams over the years claiming to be from support@btcguild.com (and many other major BTC domains).  In all of them, the emails were spoofing the origination address.  There have been dozens of BTC based websites that have had database leaks over the years which is likely how your email address got on a list to receive the phony emails.  MtGox, Bitstamp, and Bitcointalk have all had complete leaks of all user email addresses over the years (and in some cases, passwords to match).

My inbox is generally filled with "invoices" and similar claims from about a dozen different sources (all spoofed headers).  KNC, BFL, MtGox, Bitstamp, BTC Guild itself [my favorite], and Bitmain.  In all cases, they have a Java (.jar) file attached with a filename like "Invoice 89324".  Obviously, it's stupid to ever open a .jar file from an email attachment.  You will probably never in your life receive a '.jar' file unless you're a Java developer passing application builds over email.

Just going to go on record saying that if you actually fall for a phishing email claiming to be an INVOICE PAYMENT from BTC Guild, turn off your computer, and put it in a garbage bin.  You're not sophisticated enough to use the modern technology, let alone Bitcoin.

EDIT:  Posted this because I just got a copy of the email in my inbox for my old address used for Bitstamp.

Greetings,

Has anyone else noticed a sudden decrease in their worker charts as of around 4pm (GMT) yesterday?

I have an Antminer S3 pointed at Slush and BTC Guild in balance mode and both the miner stats and Slush's stats report a constant 230GH/s to each site, but the BTC Guild charts show a sudden drop down to around 170GH/s and I cannot work out why, so wanted to see if it was a reporting issue for everyone or a problem somewhere for me.

Cheers n beers

My stats look perfectly ok around that time - nothing outside the normal range (I use the eu.stratum server).  Possibly it was some kind of intermediate routing issue which was not local either to you or the server.

I actually had an increase in worker performance my charts had been going up and down like a toilet seat cause I set share difficulty so high but as of yesterday they actually leveled off at exactly the hashrate I'm sending to btcguild.

Thanks for the replies gentlemen, this is very strange.

My stats went down from 230GH/s to 170GH/s and have remained at that level for 36 hours now, whereas the other half of my hash power going to slush has remained constant, as has the S3 itself which is sitting at 465GH/s. I could understand if the Slush stats had gone up (compensation for low BTC Guild) or down (AntMiner/connection issue) but since everything else remains the same, I am (easily) confused Sad

I have switched over to the EU server and will see what happens.

Thinking back, I had a similar issue with both Slush and BTCG when I first fired up my S3+s.  Initially I let the pools set their own difficulty levels, but when I changed it manually to a minimum of 256 for each worker on each pool I started getting better reported hash rates.  Each S3+ is balanced between the two pools, and each is set up as a seperate worker.  Of course, the optimum setting may be different for an S3 and so YMMV, but it could be worth experimenting.

Thanks for the replies chaps. Not sure why, but the solution seems to have been to point at the EU server (As suggested by Sir Alan)....see below: -

http://www.hpmuirt.com/images/temp/BTC%20Guild%2072%20hours-2.JPG

As you can see, as soon as I switched to that server, my reported speed and thus rewards came back up to normal and have remained there.

Cheers n beers

Fixed a problem with entering a new address being reported as invalid.

There were no connectivity issues with the servers, so it sounds like the problems you were having aren't totally fixed.

Yet another batch of phishing emails, now using support@btcguild.com instead of info@btcguild.com.  Once again, they are completely bogus, they aren't even targeted at users of BTC Guild (though I'm sure some BTC Guild users have received them as well).

So once again:  If you fall for something so painfully stupid, please destroy any and all of your electronics because you are a danger to the internet.  Anybody stupid enough to fall for a .jar attachment phishing email is obviously not running a functional computer, but some kind of virus breeding pit which is spewing out spam, worms, and UDP packets with reckless abandon.

Nope, stupid is the correct word.  It's careless to click on a link that was actually disguised or slightly misspelled in a clever way (vv instead of w, l instead of I, etc.).  It's stupid to click on an attachment to an email with the subject "Invoice Payment Confirmation" from a company that doesn't even have invoices.

EDIT:  Actually, it's pretty stupid to be clicking any email attachment at all unless you were expecting it, even if the subject/company/attachment name make sense.  Also it's pretty stupid to not notice a '.jar' extension.  And if the excuse is your email client hides extensions...that's also quite stupid.

EDIT #2: TL;DR:  I'm a tech elitist who has no issue with blaming the victim for their own stupidity.

What degree of foolishness would you assign when the person doing the clicking has never even had dealings with the company named?
