http://www.reddit.com/r/Bitcoin/comments/1zaqvy/bitstamp_email_list_used_to_spread_mtgox_malware/I have a domain that I use to create unique emails for signing up at all kinds of services. It's all explained at bustspammers.com. Today I received this email:
---------------------------- Original Message ----------------------------

Download Documents
This is the plain-text version. In the original HTML email, the "Download Documents" link led to a page on deseobc.com distributing malware (a .pif executable, they attempted to make it look like a .pdf). This means one of three things:
Bitstamp is actively pushing malware onto their own clients.
Someone stole Bitstamp's email list.
Bitstamp sold their email list to scammers.
Knowing that many Bitstamp users likely were also Mt.Gox users and might be easy targets, provides an obvious motivation for a scam. I asked Bitstamp for comment, will update this post if I hear anything back.
Bitstamp's email list was confirmed stolen ~2 weeks ago, when a boatload of emails claiming to be from
support@btcguild.com (but not sent from any of the BTC Guild mail servers) went out talking about a 3.201 bitcoin transfer. After replying to the people shouting at me for being a scammer, I was eventually able to narrow the source of the leak to Bitstamp at the very least, and likely a few other sources on top of it.
I informed Bitstamp that they had at least a breach on their email list, if not the rest of their system. At first they denied it, but in a follow up they eventually admitted to it.They then sent out a little security update email mentioning 2FA/password security.
I can confirm 3 same email "from" mtgox"
