Virginia election officials have decertified an electronic voting system after determining that it was possible for even unskilled people to surreptitiously hack into it and tamper with vote counts.

The AVS WINVote, made by Advanced Voting Solutions, passed necessary voting systems standards and has been used in Virginia and, until recently, in Pennsylvania and Mississippi. It used the easy-to-crack passwords of "admin," "abcde," and "shoup" to lock down its Windows administrator account, Wi-Fi network, and voting results database respectively, according to a scathing security review published Tuesday by the Virginia Information Technologies Agency. The agency conducted the audit after one Virginia precinct reported that some of the devices displayed errors that interfered with vote counting during last November's elections.
