600K Cable Modems Have 'Backdoors In Backdoors'
 

So many "Yo dawg! I heard you like backdoors in your backdoors" jokes to be had, so little time. 600,000 Arris cable modems could be affected by a "backdoor-within-a-backdoor", according to a security researcher. Bernardo Rodrigues, a vulnerability tester with Brazil's Globo TV network, posted that he discovered the undocumented library within three Arris cable modems. However, using the search engine for internet-connected devices, Shodan, this found that in fact, 600,000 modems were affected.
