I think it makes nice story but I would be very surprised if such a virus could spread. You have many router brands and versions and you would need to develop and test your firmware on many of those to make sure it can spread. Also, correct me if I am wrong but not many routers have easy way of uploading new firmware.
- Xylakant 13y agoWell, base your virus partially on DD-WRT or any other open source router OS and you're in the game. Consumer routers usually have a button "upload new firmware" somewhere in the administrative web UI.
- iuguy 13y agoYou do know that there's more than one hardware platform for routers, right?
- noobface 13y agoYou'd be surprised how similar they are, at least the consumer versions.
- iuguy 13y agoOk, so you have a lot of stuff based on similar SoCs and common platforms like MIPS (although ARM is in use it tends to be more low power on consumer routers, broadcom's MIPS certainly is the major player). However most of the routers have different components, memory configurations and here's the bit that kills random firmware upgrades: Different Memory Technology Device (MTD) layouts. Think of this a little like partition layouts. The flash upgrade process will vary by vendor and will often flash MTDs of specific sizes. If the sizes don't match, it won't work or worse it'll brick the device.
