Scary phishing attempt...beware!


I'm an evangelist about the danger of e-mail spam and phishing attempts crafted to lure you to click on links in an e-mail (I'm always warning my wife not to click on e-mail links), but this one had me doing a double-take. My family and friends send me e-cards from time-to-time, and although I feel that e-cards are by and large as annoying as spam, I appreciate the sentiment (and will often go to the e-card link). I received this e-mail the other day telling me "you received a postcard from a family member", and without thinking I opened the e-mail. Fortunately, there were several suspicious clues that jumped out at me before I clicked on anything, but by and large the message was pretty well crafted (netfuncards.com is a real e-card service). Read on to learn more about this clever phish...
See the mail details below...I removed all the IP addresses in the URLs (i.e. 10.34.121.10 for example) so no chance of anyone accidentally going there:

FROM: netfuncards.com [jig@iland.net]

The first thing that jumped out at me (and you too, probably) is there is no name included of who in my family sent the card. The second thing that should alert you is that the email address is not even in the same domain as netfuncards.com (iland.net), which is unusual. Then, there's the fact that a FQDN (like netfuncards.com) is not used in the links to my card. No respected web-service on the Internet would typically use anything but an FQDN in such e-mails. After some forensic investigation of the supposed e-card hotlinks themselves, I found that they were actually registered to some cable provider in the Netherlands (netfuncards is D.C. based). Other users online who have posted warnings on this same phish say the actual web-sites try to coax you to download or install an "Outlook plug-in". Finally I visited the real netfuncards.com site and cut/pasted my "e-card number" into the required field as instructed and of course could find no e-card. Busted! Remember, if someone you know, or a site you can verify sends you a link, it pays to still be suspicious. When something appears out of the blue unsolicited, look it up online. Perform a Google search of the subject line text, and read what other users may have posted on it. Chances are the first page results will reveal if it's a scam. Never visit a link directly from an e-mail. Go to the site's main page and try navigating through the real website instead of clicking through from the e-mail. It just might save you from a virus or worse. I'm pretty good about this stuff and admit to being a tad paranoid, but this one came pretty close to fooling me at first.

I got two of these emails this morning, from two different card companies. I did click on the link shown in the first email (before I received the second, but became suspicious when card did not immediately load and quit my browser.
Question: Aside from my ending up at a bogus site that tries to cox confidential info from me, is there any other potential security issues? Could clicking on link give phisher access to my computer files, passwords, etc?

It would depend on the nature of the malware payload you may download or install. It could do a lot of nasty things including what you listed...keylogger, remote control of your machine, damage your files, hide from the OS, and replicate itself to other un-protected PCs on your home network.
