The bad thing is that sender has managed to get SPF and DKIM right because the email has been sent through Sendgrid: Code: Received: from o1.em.coinbase.com (o1.em.coinbase.com. [50.31.37.137]) Code: Received: from o1.em.coinbase.com (o1.em.coinbase.com. [50.31.37.137]) Real sender is probably Code: Received: from MTYwNDc2NQ (unknown [5.101.100.198]) which is a DigitalOcean customer. Title: Re: Fake Coinbase Email Scam Post by: cconrad0825 on April 08, 2015, 07:38:11 PM Thanks for the follow up info kseistrup. Is there a thread already about how you got that so other's can do it for this and other suspicious emails?
Title: Re: Fake Coinbase Email Scam Post by: kseistrup on April 08, 2015, 07:50:10 PM Thanks for the follow up info kseistrup. Is there a thread already about how you got that so other's can do it for this and other suspicious emails? Not really, I just looked in the raw email headers (the first two code sections), and did a “whois” lookup of the offending email address. I don't know about Windows, but mostly anyone on Linux should be able to do that easily. Title: Re: Fake Coinbase Email Scam Post by: kseistrup on April 08, 2015, 07:54:56 PM PS: The important thing here is that e.g. Gmail doesn't mark these emails as spam because both SPF and DKIM are legitimate. Even the reverse DNS is correct (because of the Sendgrid relation). The only thing about the email headers that gives this away is the Digital Ocean address.
(Of course the email is a blatant scam — I mean, if Coinbase could do a 50% profit in just 10 days they wouldn't need my money in the first place. Also, why do they ask me to send my investments to a Blockchain account? — but the email headers are well forged.) Title: Re: Fake Coinbase Email Scam Post by: Deathwing on April 08, 2015, 09:46:48 PM Quick tip;
If it says "youremail before @, bla bla bla bla" it's probably spam, always hover over link if you aren't sure if it's legit or not, for example a blockchain link can be seen like blokchain.info, make sure to double check the address.

What makes you think these are blockchain accounts? You can generate a QR code through BC by simply adjusting the address: https://blockchain.info/qr?data=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&size=400 Title: Re: Fake Coinbase Email Scam Post by: cassini on April 08, 2015, 11:42:42 PM but the email headers are well forged. Coinbase's Sendgrid account (their backup mail system) had been compromised, seehttps://www.reddit.com/r/Bitcoin/comments/31wjt7/coinbase_scam_email_alert/ Title: Re: Fake Coinbase Email Scam Post by: Cyrus on April 08, 2015, 11:45:43 PM Duplicate post.
