The U.S. agency charged with ensuring that voting machines meet security standards was itself penetrated by a hacker after the November elections, according to a security firm working with law enforcement on the matter. The security firm, Recorded Future, was monitoring underground electronic markets where hackers buy and sell wares and discovered someone offering log-on credentials for access to computers at the U.S. Election Assistance Commission. Posing as a potential buyer, the researchers ... discovered that the Russian-speaking hacker had obtained the credentials of more than 100 people at the election commission after exploiting a common database vulnerability. The hacker was trying to sell information about the vulnerability to a Middle Eastern government for several thousand dollars. The election commission certifies voting systems and develops standards for technical guidelines and best practices for election officials across the country. The researchers said the hacker had an unusual business model, scanning for ways to break into all manner of businesses and other entities and then moving rapidly to sell that access. We don't think he actually works for any government or is super sophisticated," Barysevich said. In the case of the election commission, the hacker used methods including an SQL injection, a well known and preventable flaw, obtaining a list of user names and obfuscated passwords, which he was then able to crack.
