Seems like scammers are trying everything they can to phish for bitcoins these days. Simply follow the golden rule:
Don't click on links from people you don't know.

jar files are java executable, donīt download it (there is only a very small amount of software that is actually a jar, and you would rememer ordering such a software).

This has happened with several spoofed email adresses of hardware manufacturers, so it is more likely the actual email list was leaked on another platform
(or that all email adresses from these manufacturers are stored in an unsafe way)

What a pity ,that they can't find a decent job. Instead go around the web stealing people money that doesn't belong to them.

The question noone seems to be asking is....how did they get those emails in the first place? It seems there may be a common thread there. Was BCT hacked and we are not aware of it? Or were one of the vendors hacked and the emails gotten that way? There clearly was a security breach or else the scammers would not know to specifically target people who have bought mining hardware.

About a month a go I was getting these spam emails with a jar attached from knc, cointerra and cloudhashing. Never registered with two of them so I'm guessing my emailaddress was leaked from somewhere else.

recently i started getting phising emails from various well known businesses such as btc-e , minereu , and many other exchange sites.

Not sure if it is only me but is there something i am missing? I will get about 4-5 a week. Anyone else having this same problem?

There's been so many bitcoin site hacks over the years that if you've been in it long enough it's all but guaranteed you have an email on a list somewhere.  If you're lucky, you used a throw-away/spam only address.  MtGox and Bitstamp both had database compromises that at the very least dumped a complete list of all their users emails on multiple occasions.

Just be careful about opening attachments as usual (aka: don't do it).  I probably get about a dozen a week with .jar files attached pretending to be invoices/miner screenshots.
Also, btctalk was ofcourse hacked a while back so not surprising my emailaddress is out there.


Also, this spam/phishing with jar files is nothing new:

I just got an email with a shipping notice from Bitcoinrigs.org, even though I've never ordered anything from them.
The reply to address appears to be from Stamps.com, through I didn't actually load any of the content to look at it.

I wonder if they're related?

Maybe it's BFL or AMT both desperate for cash seeing how they could not get away with scamming new customers and need other sources of revenue :P

For new uses, simple ways to protect your coins:
1) Don't access the web/internet on the machine that hosts your wallet
2) If you have the time, move/convert your wallet (the file with your private keys) into a paper wallet.  Paper might be ancient but I have yet to see a trojan/malware that is able to read paper (except somebody hacking your webcam)
3) If using a digital wallet file, encrypt it with a password/passphrase that is unique (not used anywhere else) and is difficult enough to not be bruteforced
4) Learn to use cold wallets and put the majority of your coins in that wallet

Learn to use the tools that the community has created.  There are several alternatives to the base Bitcoin-QT that can offer increased security options.  If you have a significant value of coins it may be prudent to invest a little time learning how to use something like a cold walllet with Armory or one of the other alternative clients:

Armory has a walkthough of how to make a offline/cold wallet here:
