A group of security researchers has found that some cameras are vulnerable to ransomware attacks via Wi-Fi or hijacked computers (using the USB connection) that can render a camera and its photos entirely usage until a sum of money is paid to the hackers.

Check Point Software Technologies has shown (as seen in the video above) that Canon DSLRs (it’s not clear if other cameras are also affected) are susceptible to ransomware attacks, an increasingly common exploitation in which a hacker disables a device until the owner pays a ransom to regain control. As more and more electronics gain internet connectivity, these attacks are becoming more common, particularly since manufacturers typically don’t put the same sort of effort into fortifying the network security of small electronics as they do into computers. Canon released a statement in which they offered some barebones tips to avoid being susceptible to these attacks and noted that there have been no known instances of such an attack occurring. They did not indicate whether they plan to fix the vulnerabilities through firmware updates, so it probably doesn’t hurt to be a bit more careful to protect your photos.

Warnings about connected vehicle vulnerabilities have been a steady drumbeat for years. Now a consumer-advocacy group is putting it in starker terms, suggesting a mass cyberattack against such vehicles could lead to Sept. 11-level casualties.

California-based Consumer Watchdog has issued a 49-page report that paints the dire picture and urges automakers to install 50-cent “kill switches” to allow vehicles to be disconnected from the Internet. The report highlights numerous widely reported instances of remote vehicle hacking, such as a 2015 demonstration involving a Jeep Cherokee left crawling along a St. Louis-area freeway.

“Millions of cars on the internet running the same software means a single exploit can affect millions of vehicles simultaneously. A hacker with only modest resources could launch a massive attack against our automotive infrastructure, potentially causing thousands of fatalities and disrupting our most critical form of transportation,” the group warns.
