Researchers Hack Over a Dozen Home Routers

An anonymous reader writes "Security researchers at Independent Security Evaluators have published a report demonstrating that a slew of home and small office (SOHO) routers are vulnerable to previously undisclosed vulnerabilities. The report asserts that at least thirteen popular routers can be compromised by a remote attacker, and a number of them do not require knowledge of credentials or active management sessions. Some of the routers are not listed as they work with vendors to fix them, but there are 17 vulnerabilities disclosed, with another 21 pending release. An article on CNET includes an interview with some of the researchers."

    An older computer redone with a FreeBSD install makes an excellent router and is extremely secure. I would suggest anyone who is comfortable with a *nix command line use this solution as I've found it to be virtually bulletproof.

      I like these embedded devices because they are low power (save you money on an ongoing basis) and do the job. Many even offer some nice things like switch management (e.g. creating vlans) if you use custom firmware. That said, if you do switch to a custom firmware, chances are good that you are immune to these vulnerabilities.

      These security researchers don't really count on the later though. They advocate requiring these devices to require signed firmware. That means no custom firmwares, so if your manufacturer ever abandons the device, and security vulnerabilities are later found, you really can't do anything about it. I like custom firmware for not only that reason (e.g. it uses software that is generally better tested against threats) but because it ads features that most OEMs require you to pay a LOT extra for.

      I hope none of these vendors take the signed firmware advice, or at least allow you to sign your own. But many here already know how that goes. I think Netgear is the only one that might set itself apart in that regard as they carry certain models that are explicitly advertised to the customer as being able to use your own firmware.

      Probem with Pi is that its network throughput is kinda bad. I have a 50mbit pipe, and pi seems to top out at 35. Kind of problematic for XBMC use for me as well in that playing blu-rays results in buffering for me for the high bitrate ones (add nfs/smb overhead and you dip down to 30mbit - some of my blu-rays peak at 39mbit.) Still trying to figure out of the problem is just me (I only got the pi a week ago) or if everybody with high bitrate ripped bd's has this problem. And no, I don't want to transcode them to a lower bitrate.

  10. Won't help you by dutchwhizzman · · Score: 2

    Using a firewall box behind the router your ISP mandates you use, will not help you against a number of threats. Basically, they take over your router, put a sniffer on it and they can sniff all your internet traffic. The extra firewall may or may not prevent them gaining access to your computers behind the IPV4-NAT your router usually does. That's the only protection an extra firewall might give you. I'm saying might, since slight misconfiguration or access to a hackable service behind the firewall will negate all security that firewall is giving you.

    Advocating FreeBSD, or any other specific solution is not helpful here. There are plenty of other adequate firewall solutions, more or less regardless of the operating system they may be running.

    In practice, it will only help if manufacturers and vendors will be found liable for security flaws in their equipment and will automatically have to pay not just the price of the device and all damages to all customers that have bought it, but also a fine if they are found to be negligent. It's clear that vendors don't take security seriously (all tested devices were hacked) and ISPs aren't either. Home users can't be expected to know their security details up to such a high level so can't really be blamed for trusting their ISP or a leading brand to take care of security adequately. ISPs, vendors and manufacturers are supposed to know and actively secure their devices. Since they don't seem to care, some sort of threat should be put in place to make them take this more seriously.

And only because I "hacked" into it at some point and observed the malware in action, and reported my results back to the ISP. I thought my method (though it required some circumvention) was an intentional feature of the router. I didn't realize it was a vulnerability. Not at the time.

    I disagree. There is a demand for security, at least among some a certain set of consumers. The current problem is that apparently none of the commercially available routers appear to be worth anything when it comes to security. Every time an article like this appears on /. I keep looking for some recommendations as to what to do. And I never find anything. The only recommendation I did find was from Mr. Kitchen, about using an old computer and smoothwall. Well, first, physically that wouldn't work (the cable modem, router, and switch all live up on a small shelf near the patch panel for my house. Yes, I paid $$ to get the place wired). Second, I really doubt my ability to keep a linux box up, operating, and fully patched. Keeping the router's firmware up to date is easy (it checks itself, and will pop up on the admin page when a new firmware is available: some will even flash themselves if you allow it): a unix OS isn't going to be that easy. I really don't understand why some manufacturer doesn't use this as a marketing opportunity. There is a niche here. I'd may more (maybe significantly more) for something that is secure, works well, and meets my needs.
