chicksdaddy writes "More than six months after hacked Emergency Alert System (EAS) hardware allowed a phony warning about a zombie uprising to air in several U.S. states, a security consulting company is warning that serious issues persist in software from Monroe Electronics, whose equipment was compromised in the earlier attack. In a blog post, Mike Davis of the firm IOActive said patches issued by Monroe Electronics, the Lyndonville, New York firm that is a leading supplier of EAS hardware, do not adequately address problems raised earlier this year, including the use of 'bad and predictable' login credentials. Further inspection by Davis turned up other problems that were either missed in the initial code review or introduced by the patch. They include the use of “predictable and hard-coded keys and passwords,” as well as web-based backups that were publicly accessible and that contained valid user credentials. Monroe’s R-189 CAP-EAS product was the target of a hack in February during which EAS equipment operated by broadcasters in Montana, Michigan and other states was compromised and used to issue an alert claiming that the 'dead are rising from their graves,' and advising residents not to attempt to apprehend them. CAP refers to the Common Alerting Protocol, a successor to EAS. A recent search using the Shodan search engine by University of Florida graduate student Shawn Merdinger found more than 200 Monroe devices still accessible from the public Internet. 66% of those were running vulnerable versions of the Monroe firmware."
