A security expert at Rapid 7 found that common videoconferencing equipment could give hackers access to company conference rooms and boardrooms. Hackers could remotely infiltrate conference rooms in some of the top venture capital and law firms across the country, as well as pharmaceutical and oil companies. Overall, the findings mean up to 150,000 systems across the internet could be vulnerable, according to Rapid7 security expert HD Moore. He hopes that by exposing these flaws it will persuade vendors and end-users to take the issue of video-conferencing security seriously.
