Drive-By Pharming In the Wild 205

Posted by kdawson from the just-change-the-default-password-already dept.
An anonymous reader writes "Symantec reported Tuesday that the first case of drive-by pharming, in which a hacker changes the DNS settings on a customer's broadband router or wireless access point and directs the link to a fraudulent Web site, has been observed in the wild. The first drive-by pharming attack has been observed against a Mexican bank: 'It's associated with an e-mail pretending to be from a legitimate Spanish-language e-greeting card company, Gusanito.com,' says Symantec Security Response principal researcher Zulfikar Ramzan. Inside the e-mail is an HTML image tag but instead of displaying images, it sends a request to the home router to tamper with it."

What you are telling me is that a box on the edge of your network, a box that presumably is very open to abuse also happens to hold a huge volume of data, not too bright, even if it is just TV shows. Personally I'd grab a modest piece of hardware suited to the role and ensure it was locked down as tightly as possible.

      If you have a home network, there are several ways to secure it. Every router that I have ever owned have several characteristics. Look for the 'reset' key, make sure it is there and not like Asante where you have to short terminals 3 and 8 on the serial port...showin my age there folks. Make sure it is a real router and not a windows appendage. Do NOT use a PCI modem that you cannot disconnect fast. Use an external modem on a SERIAL port. Do not use a combination cable modem/router. This is foisted on many users, and as a default feature sets up remote administration from the outside. That remote admin 'feature' is 'supposed to allow customer engineers to help......' you out of all your money. Don't surf as administrator if microsoftintheheady or as root if a linux penguin. Thats just askin to get hosed. Yeah, I'm a ramblin old fart, but all these things I have picked up from experience. Definitely change the default password, 'admin' or whatever on the router to something realllly strange and long. Write that password down and put it in your wallet, your wife's ring box, or whatever. Do not even try to memorize it as you will forget it when you need it. Don't use 'DHCP' that routers and network vendors want you to do. This means that all home networks are on 192.168.1.0 or some predictable net address that all hackers try first. Use a REAL network with a real address like 192.168.205.89 or something. This forces hackers to really fail many many times in guessing your network setup. With a real network, hand out your own addresses and make them random in the third and fourth hex digits so that hackers will have to guess out each and every terminal on your net. Now add MAC security to your router so that the hacker not only has to correctly guess from a crore of non standard addresses to address it, but only those with the right computer NIC can even be qualified to guess the password! Having a switch available to shut down suspects in a hurry helps too. I could go on, but if you have followed all this rambling, print it out and do it.

        Good advice.

        But you forgot something: When a friend brings their PC/PSP/PS3/Wii/Xbox/iPhone/iPod over, and wants to use it with teh Intarwebs, go ahead and set it up and give them the passphrase and IP assignment, but make sure you destroy your friend before they leave.

        You can't allow any chance of your uber-obscurity leaking outside, right? Eventually, you'll eliminate all of your friends, but that has the nice benefit of eliminating the potential leaks.

        Naw, better to keep it simple. Don't run as root/admin. Set an unusual password (something other than your SO or child's name is adequate). Set a different, unusual, and lengthy, WAP passphrase. Use the strongest encryption you can with the devices on your network (AES, AES / TKIP, or just TKIP, in order of preference).

        Done.

        MAC filtering? Disabling DHCP? IP address range hide and seek?

        Bullshit. All that does is make it harder for you and the people you trust to use the network. And if I, the creepy dude in the van across the street, get to a point where any of those stupid tricks will start to matter, they won't make any difference at all. If I'm clever enough to get past WAP, then I'm clever enough to clone a MAC address while sniffing past the rest of your security-through-obscurity features.

        [And what's all that talk about serial ports? Are we still in 2008, or did we just jump back 10 years?]

      • You are confusing static addressing (which doesn't help) with choosing a less obvious IP range (which does). It's fine to use DHCP, just change the address you use to something non-default - anything in 192.168.0.0/24 or 172.x or 10.x ranges (check RFC1918) is good. That way the malware on a PC will have to scan first to know what to attack, which raises the bar slightly, although at Ethernet speeds it wouldn't take very long to scan the whole 192.168.x address range.

        BTW the 'third and fourth hex digits'

      • With a real network, hand out your own addresses and make them random in the third and fourth hex digits so that hackers will have to guess out each and every terminal on your net.

        Sounds like someone doesn't understand how DHCP and subnetting work. You can change the DHCP addressing range on your router so that it gives out, say, 192.168.100.0/24. There is no need to use manual addressing unless you have untrusted people able to physically plug into your LAN. Also, IP v4 addresses can be expressed in

      How about simpler... the router will NOT function until you set a username and password. It routes no traffic and redirects all web requests to the "Hey stupid user, pick a username and password, no you cant use linksys, router, admin, or password."

      that way the same binary image can be used on every router. Out of the box they do not work, they requre the user to have at last 35 brain cells to get it to work and in the process will be safe from this crap.

      Or better yet, make the default password the last 6 digits of the LAN side MAC address, that can't be terribly hard to manufacture.

      that wouldn't really help, drive-by attacks access the router from the lan side anyway, so would already have access to the lan side mac address.

    The paper shows that BIND 9 DNS queries are predictable i.e. that the source UDP port and DNS transaction ID can be effectively predicted. A predictability algorithm is described that, in optimal conditions, provides very few guesses for the "next" query (10 in the basic attack, and 1 in the advanced attack), thereby overcoming whatever protection offered by the transaction ID mechanism. This enables a much more effective DNS cache poisoning than the currently known attacks against BIND 9. The net effect is that pharming attacks are feasible against BIND 9 caching DNS servers, without the need to directly attack neither DNS servers nor clients (PCs). The results are applicable to all BIND 9 releases [1], when BIND (the named daemon) is in caching DNS server configuration.

    I live in Mexico, and yes, the bank name is Banamex (owned by Citibank) and this is how the hack works:

    The most prominent ISP in Mexico (Telmex) uses 2wire gateway modems, most of them wireless enabled. Security is turned on by default using serial numbers so no one from outside can login "easily".

    However, there is no default security from the inside, so the gusanito.com postcard contains a malicious flash program that sends a special URL to the modem that adds a DNS entry to its local name resolution table pointing www.banamex.com to a pharming site.

    Next time you open IE or any other browser and open www.banamex.com you'll get redirected to the other site.

    This easily solved putting a user password on the modem configuration, but not all people care to do that.
