In this blogpost we will look deep into a spam campaign, where unlike other possible scenarios, the victim is infected by opening and running an email attachment. In the beginning of this year, we blogged about a spam campaign with a different spam message – a fake email from the popular WhatsApp messenger. This time we will look at spam email which tries to convince the victim that it originates from his bank. The malicious email contains contents similar to the following one:
Subject: FW: Bank docs
We have received this documents from your bank, please review attached documents.
How’s this for a good phishing scam? Everything seems legit:
1. From email is “firstname.lastname@example.org”
2. No misspelled words and has decent grammar (however, some punctuation inconsistency)
3. Copyright (c) symbol next to the university name
4. Gmail did not filter it as spam, but left it in my normal inbox
Yes, if I had ever attended that particular university, I might have fallen for it.
PLEASE NOTE: University of Texas has nothing to do with this email.
Today, I received an email from one of my coworkers (yes, even careful employees of security vendors are in danger:) ). This email has more recipients and contains only one link, without any text or subject.
Fortunately, I am a really paranoid person about emails containing only a link to an unknown site. At this link, you can notice two really suspicious things: The directory is images and there’s a file called yahoo12.php. That should warn users to avoid clicking on this link.
