The Insecurity of Short URLs
I just got an email from the awesome folks at Joyent alerting me that someone was using Culld.us to redirect to their phishing scam site.
I promptly blocked their IP, wiped the offending URLs from the system and reset the cache.
This experience brings to mind an after hours conversation I had with a couple U of MN network security guys about inherent security risks of short URL services.
Cullect currently recognizes 83 URL shortening services.
EIGHTY-THREE
I’m hard pressed to think of 83 providers of anything (outside of entertainment services). That’s a measure of demand if anything. Even more reason publishers should – as Dave Winer recommends – pull this capability under their own umbrella.
