Industrial robots (those used in fields like aerospace, automative, pharmaceutical, and welding) pose an enticing and dangerous opportunity to hackers since many of them are actually connected to the Internet, a new report finds.

Trend Micro and researchers from the Polytechnic University at Milan released a report detailing how hackers could compromise industrial robots, making various industries susceptible to hacks similar to the recent ransomeware attack.

One problem: The researchers found many of the robots they scanned during a two-week period were connected to company networks or the Internet — " some of which even provided unrestricted access using anonymous credentials (i.e., the authentication system was disabled)," they wrote.

Another problem: Much of the software used in these robots is patched together or not properly updated. They found that many had embedded remote access devices, which allow someone to connect to and control the robot from a remote location, as if they were on the local network. And, the researchers noted that "some vendors implement safety features such as emergency stop (e-stop) buttons in software," meaning a hacker could shut down the industrial robots.

One quick thing: The researchers also found that a complete robot with its controller could cost a hacker anywhere between $13,000 and $35,500.

Facebook said Wednesday that it was removing a series of ads from President Trump's campaign that linked American acceptance of refugees with increased coronavirus risk, a connection Facebook says is without merit.

Why it matters: The ads were pulled after they received thousands of impressions and are a sign that the Trump campaign continues to test the limits of social media rules on false information.

Over 73 million people watched the first debate on TV

More than 73.1 million people watched the first presidential debate on television on Tuesday night, according to Nielsen ratings.

Why it matters: While that's a sizable audience for any American TV program, it's down more than 13% from the record number of TV viewers who tuned in for the first debate of the 2016 election. The chaotic nature of the debate and the overall uncertainty around this year's election may have pushed some viewers away.
