The Cyber Intelligence Sharing and Protection Act now has more than 105 co-sponsors, and some fear the bill could go further than SOPA and PIPA in threatening online privacy. SOPA and PIPA were finally discarded earlier this year after resounding online protest changed the debate, but the same doesn't yet appear to be the case with CISPA.
According to the Electronic Frontier Foundation, H.R. 3523 "would let companies spy on users and share private information with the federal government and other companies with near-total immunity from civil and criminal liability. It effectively creates a 'cybersecurity' exemption to all existing laws."
The bill could sneak through Congress quickly once it's back in session, so be sure to track its progress.
