Since yesterday, I receive forged mails which are targeted at me. They use personal information, seem to come from one of my friends and only contain links to these web sites:

http kaosbolaclothing.com/ceremonyemploy/Dean_Edwards28/
http www.sidat.com.mx/engagediatmosphere/Matthew_Bailey44/

(links disabled to prevent someone from accidentally following them).

What should I do now?

[EDIT] Some more information:

  1. The mail addresses me personally (by first name)
  2. The sender is the full name of my friend (no typos) but the attacker is using different sender emails (probably forged).

Here is the mail header (personal information replaced with ${...}):

  1. I'm pretty sure my server isn't hacked

    Can you clarify what you mean by personal information? Is it more than what's in your friend's address book? Aug 23, 2012 at 8:26
  • I've seen this kind of thing several times with Yahoo mail.

They probably did come from your friend, but not intentionally. There are two likely scenarios:

  1. A spammer knows your friend's email password, and is using details from previous emails to scam you.
  2. Your friend's computer has malware on it, and it's using their email account to send spam. In this case, it's probably pulling names and other details from the contact list.

In either case, tell your friend and get him/her to clear up their machine and change their password. Make sure it's in that order, otherwise malware could just keylog the new password.

In terms of the sites, it's difficult to know whether they're dedicated phishing/spam domains, or just sites that have been hacked into. In the USA it's a federal crime to send scam emails, so you can report it via IC3.

Update: It's likely that the attacker is monitoring your communications (e.g. Facebook, Twitter) and using them to target you directly. At this point it may be effective to just reply and say "I know you're trying to phish me, I'm not falling for it, bugger off."

  • And, could it be a faked sender, using some tools like FakeMailer, so his friend email account has not been compromised, but the attackers knows it, and is trying to phish him?

  • I'm also leaning towards phishing right now. It's possible that the Yahoo account is hacked but I'm still curious how they made the connection between me and my friend. We just met a couple of times at Linux events, so there is no close relation between the two of us. Aug 23, 2012 at 8:39
  • Possible that they're monitoring conversations through other channels. Faceook? Twitter?

  • I'm not using Twitter but he might be in my list of friends on Facebook. Checking ... yep, we're connected via Facebook. Sounds like a hit. Aug 23, 2012 at 8:54
  • Are you searchable by email address on Facebook? If so, it's likely they found your profile that way.

Just to add to @Polynomial's (what seems to me to be correct) answer (upvoted), when you talk to your friend, don't approach him/her as if it's a confrontation. I've seen many folk (after being hacked) react so badly because they felt they were confronted.

I think you can quickly confirm if it is a phish by asking if he's aware of the situation or if any of his other friends have received such emails? If his account was hacked as Polynomial rightly suggested then I doubt you're alone in receiving such a spam/phish, unless for some (rare) reason you're being specifically targeted. I receive similar emails around once per month from some friend, whose webmail password has been compromised (it's interesting when it happens to a security mailing list).

Looking at the mail headers, the X-Spam-Status: No, score=-0.1 headers show that everything on the mail was well-constructed, no content appearing like a spam mail, most likely a low SPF rating on the sending mail server and the websites referenced have no prior in terms of being a phishing or compromised URL. Taken with the results below, this would seem to indicate freshly compromised sites.

I also checked the reputation of the two sites (I regularly do this on such occasions and notify the vendors and the local CERT of such sites, I'd recommend doing so). I used to volunteer at a CSIRT and such notifications are invaluable.

  1. kaosbolaclothing.com

  2. www.sidat.com.mx

From experience, I've found the Websense Lookup Tool to be the best but I no longer have a login there.

I unfortunately don't have time to actually look at the sites to see if they try to exploit anything but I'd be interested to know :)

  • Spammers, these days, tend to compromise websites and upload phishing pages. It makes it difficult to trace the hosted page back to them.

  • Yep, agreed. It's an arms race and the spammers etc are winning. I actually wrote a paper on it a few years ago for a SANS white paper when I was volunteering at a CSIRT. Like so much else in security, it's more often than not about having an "incident handling" plan, reacting quickly and properly. Aug 23, 2012 at 9:09
  • @MarkHillick: Did you just check the whole site or the specific page that I mentioned? Maybe just that single page was hacked. But then, maybe it's just targeted spam. I'm not sure whether it's worth to raise my CERT's attention or not :-/ I'm on Linux so it's probably safe to look at the web site (I could download the HTML from the command line, so no way that JavaScript could hack me) but I'm not in a position to do a decent analysis it (time, knowledge). Aug 23, 2012 at 9:13
  • @AaronDigulla Only the domain, if I'd time, I'd check the pages. You can ask a URL checker to manually review a site & they should check the complete site and then categorise it accordingly. The "good behaviour" is to notify the CERT but given the amount of attacks like this now, a CERT probably won'twant to look at it unless it's out of the ordinary or has big impact. Re. browsing on Linux being safer, see this from yesterday :) I use a VM in such scenarios. Aug 23, 2012 at 9:28
