Evolving Phishing Attacks Using Web Vulnerabilities? 179

Posted by Cliff from the how-to-protect-against-the-new-generation-of-annoyance dept.
miahrogers writes "The IRS Scam from a few weeks ago was not the the usual canned phishing attack; it exploited a vulnerability in the IRS benefits website to make users think they were at a government site. Also, according to Infoworld, eBay's own fraud team was tricked into thinking a phishing email was legitimate eBay correspondence. Mix the above IRS exploit with a phony email and you have misplaced trust that foils even professional fraud teams. Interestingly enough, the newest addition to my bookshelf predicted these attacks in full detail. From chapter 4: 'Combined with vulnerable Web servers allowing the "trusted" domain to launch the attack, it will be harder to determine whether the email is or isn't legitimate. When a person turns in the e-mail to question its legitimacy, due to the known marketing campaign a tech support representative may overlook the fraud report and tell the customer that XYZ company did send out such a marketing e-mail and it is OK to click the links.' Are phishers using this book as a tool, or is it a legitimate prediction? As an IT professional, what efforts should our corporate IT department be making to proactively to eliminate these vulnerabilities?"

Most webmail clients don't work well with it, how could they? they'd need to store your private key, which I wouldn't trust any free webmail client with. I'm surprised that EBay and Paypal don't support PGP encrypted/signed email. I get tons of phishing messages with their names on it. They also send out a lot of email, as it's often the only way to communicate with their customers. I think it would help out their customers a lot if they provided a way to verify that a message was actually from Paypal/Ebay.

      • I agree with you that public key cryptography could help sophisticated users avoid these schemes more easily. However, there are several problems with this approach which must be resolved before such a solution could become widely adopted:

        1) As you said, the PGP integration with popular e-mail clients, and web clients in particular, is either non-existent or cumbersome.

Currently I can run my e-mail server for free, and get the benefits of IMAP and other features without paying extra fees to various organizations. I do have to relay outgoing mail through my ISPs mail servers, but otherwise it works fine.

            How would I set up SPF for this?
      • The biggest issue I have with SPF is that too many of the big players don't want to use it. Or they use it but seem indecisive about what hosts are allowed to send email for them. For example:

        yahoo.com, peoplepc.com, sbc.com, fbi.gov, irs.gov, irs.com, whitehouse.gov - no SPF records at all

        gmail.com, google.com, aol.com, verizon.com - includes ?all in their SPF record which basically says "these are my authorized senders but other hosts are probably ok too.

        hotmail.com, msn.com, charter.net, ebay.com, usba
        • Companies like ebay, paypal and citibank need to be sure that if someone sends a legitimate email, it goes through even if IT forgot to add a new mail server to the SPF record (or whatever it might be). That email might be something from paypal telling you that they have frozen your account and that it is now in the red and that if you dont pay up right now, they will send debt collectors after you. Or something else important.

    Hopefully, at least 3/4 of those briefed will remember this information and put it to good use.

    You can also buy "Phishing Exposed: Uncover Secrets from the Dark Side" to help explain the attacks.
    This is essential reading for those who want to learn the ways of the Farce.
    • Another useful book that can raise awareness and understanding is "Phishing: Cutting the Identity Theft Line," by Rachael Lininger and Russell Dean Vines. It covers everything from the basics to detailed strategies, with summary sections of action points for IT staff, users and financial execs. About $20.

    Phishing attacks are Intelligently Designed, not evolved! It is improbable to the point of absurd for a random number generator to produce a phishing website in the same way that it is absurd for random events to result in a new liver. Only the actions of an Intelligent Designer like a programmer can produce a phishing vulnerability.

    There's a fairly simple way to avoid these attacks: never ever trust any link in any e-mail, period. If you think the e-mail is legitimate, ignore the links in it and use your own bookmarks to go to the relevant site and check your account or similar page there. If it really is legitimate, there'll be a way to find the information without depending on the e-mail links. It's not completely fool-proof, but for a phisher to fool you when you do this they'd have to vandalize the legitimate web-site to include their links on it's actual pages. That's harder than just faking an e-mail.

    Why should I have to tell anyone this? It's received wisdom that if you receive a phone call from someone claiming to be your bank and asking to verify things like your PIN you should hang up, look up the bank's phone number in the phone book, call them yourself and ask Customer Service about the situation. First rule: never trust the identity of the other end unless you called them. Why should e-mail be any different?

  • The weak point in phishing seems to be the people's reason ... lack of, I mean.
    Sometimes we tend not to use reason and this is what phishers try to exploit.
    I receive a dozen of such emails every month. Almost all of them are pitiful attempts, clearly showing they are fake without any special check.
    Nonetheless is seems that lots of people get trapped into them.
    Maybe people needs more real education in "Internet etiquette" than anti-anything software.


  • If a well known web site claims to link to an IP address to collect your sensitive information that's a pretty big red flag.

    If a Who-Is lookup of the owner of that IP address reads: China that's another pretty big flag.

    Of course if the email is from Prince Uba-bott-toomu-slam-botta and he needs your help in liberating the jewel of Thesia you're good to go.
  • Let's look at the problem:

    1) Email arrives promising free money .
    2) User clicks or copy/pastes URL
    3) User is redirected to a site which asks for very personal information.

    The vulnerability is a PEBKAC problem.

    Some are excusing the users because the link first went to a government website. BS. That carries the implied assertion that because the government is involved people should absolutely believe what is being said, shown, or asked for .
  • It sure seems to me that a big part of the solution is to establish some legitimate trust mechanism for domains. This applies to email and to HTTP packets.

    No I don't have a solution, but to use a famous analogy, lack of trust on domain addressing is equivalent to unlocked doors. It's still against the law to open the unlocked door, but at some point you really do need to install the locks.

    The two examples feature separate problems that are both serious, but not easy to combine. The IRS phishing scam was enabled by an open redirect [netcraft.com] on the govbenefits.gov web site that allowed phishers to craft a URL that uses the govbenefits.gov URL but instead sends users to a web server in Italy. Security flaws in trusted sites are found and exploited quite often by phishing crews, who look for applications that are likely to allow redirection or cross-site scripting. The NIST site, which hosts the US cyber-vulnerability database, was recently found to be briefly vulnerable to cross-site scripting [netcraft.com].

    The eBay issue was simply a case of a tech support staffer who failed to recognize a scam domain, rather than any technical wizardry or social engineering expertise on the part of the scammers. It's a good argument for adopting defense at the browser level (i.e. toolbars and in-browser blocking) rather than counting on banks, registrars or hosting companies to shut sites down.
