Another day, another phishing scam, and an ISP that just doesn’t care

I eagerly opened my SPAM box in Gmail recently and discovered a standard-fare phishing attack email.  This particular one was impersonating USAA bank and claimed the user  needed to take action for a pending deposit.

USAA Phishing Email

Upon viewing the original source (raw copy) of the email, we can quickly identify where the phishing email came from.

Received: from ([] helo=TS-PCMV.inland.local) by with esmtp (Exim 4.69) (envelope-from <>) id 1dFJlm-0001IH-SU; Mon, 29 May 2017 05:27:38 -0700

According to DomainTools, the IP  has been assigned to Telepacific Communication, currently known as TPx Communications  as of April 11, 2017 and is headquartered in Los Angeles, CA. The WHOIS record further details the customer operating the IP address as “INLAND RHEUMATOLOGY & OSTEOPUROSIS MED GROUP”

So how did this email get through in the first place?  Interestingly, further details are found in the original source of the email:

X-Spam-Beval: 53
X-Spam-Score: 5.3
X-Spam-Report: Spam detection software, running on the telepacific email platform has scanned this email in an attempt to identify spam. The original message has been attached to this so you can view it or label similar future email.

So it appears the email was scanned by Telepacific Communication’s anti-spam software but was allowed to slip through. I reported the issue to and received a bounceback:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

host []

SMTP error from remote mail server after end of data:

552 5.2.0 FP6Vd4FrlCQzG :: CPANEL :: Message rejected for spam or virus content ::

Please include this entire message when contacting support ::

The irony of this is quite laughable since the original message was not flagged as malicious but the act of reporting it was.  I sent a follow up message to Telepacific Communication’s abuse department but did not receive any response.
