Security: Voting Machines With Windows and Back Doors in Windows Help Crypto-jacking

  • Election Security a High Priority — Until It Comes to Paying for New Voting Machines [Ed: Sadly, the US has outsourced its voting machines to a private company whose systems are managed by Microsoft]
    When poll workers arrived at 6 a.m. to open the voting location in Allentown, New Jersey, for last November’s gubernatorial election, they found that none of the borough’s four voting machines were working. Their replacements, which were delivered about four hours later, also failed. Voters had to cast their ballots on paper, which then were counted by hand. Machine malfunctions are a regular feature of American elections. Even as worries over cybersecurity and election interference loom, many local jurisdictions depend on aging voting equipment based on frequently obsolete and sometimes insecure technology. And the counties and states that fund elections have dragged their heels on providing the money to buy new equipment.

    Separately, researchers from security firm FireEye said attackers, presumably with no relation to the one reported by Check Point, are exploiting unpatched systems running Oracle's WebLogic Server to install cryptocurrency-mining malware. Oracle patched the vulnerability, indexed as CVE-2017-10271, in October.
