Cybersecurity Weekly: Trend Micro, Firefox flaw and Amazon Ring Video doorbell

Nov 13, 2019


  • A Trend Micro employee stole customer data and sold them to criminals who used the information to conduct a support call phone scam. The breach affected 68,000 customers.
  • The City of Ocala in Florida fell victim to a business email compromise scam (BEC) that ended with redirecting over $742,000 to a bank account controlled by the fraudster(s). The swindle involved a phishing email impersonating an employee of a construction company the city is using to build a new terminal at the Ocala International Airport.
  • A Utah eye clinic began notifying about 20,000 patients last week about a June 2018 breach involving a third-party appointment reminder portal vendor. Many of the affected individuals had been previous targets of an email scam last year tied to the breach.


  • A flaw in Firefox is being actively exploited to freeze the browser. The freeze occurs after a pop-up message tells users they are running a pirated version of Windows and that it has been hacked. The message appears without user interaction when they visit sites that have been seeded with the malicious code. Users have to force close the browser.
  • Two bugs in the network configuration utility rConfig have been identified, both allowing remote code execution on affected systems. Worse, one is rated critical and allows for a user to attack a system remotely – sans authentication.
