Security threat from SD/WiFi cards?

I don't have a particular instance of said problem, just curious if anyone knows how I could check to see if a wifi device has any malware on it.

I've ordered a wifi-enabled SD card (EZ Share sold by MicroDragon, China) for my camera which both stores photos and will transmit them via wifi to my home network. I'm guessing I'll need to open up the network to the card and probably some installable app on the PC.

Would it be possible for someone to install a bunch of spyware on it? While my photos are obviously not sensitive, I'm thinking this would open up everything on the PC and other networked devices for analysis and transmission elsewhere.

I wonder if I could install something on my wifi router (that links to my cable modem) to filter/trap unwanted packets.

 

I'm guessing that this question is posted in the wrong forum or might not be considered very worthy of consideration and I'll repost elsewhere. However, it does appear that vulnerable wifi access points are real and could be really used to leak secure information.

The simple answer is - most likely no.
Remove the card, mount it in Linux and see how it works and what it does.
But if you suspect something, why use it then?
