Millions of IoT devices are vulnerable to cybersecurity attacks due to a vulnerability initially discovered in remote security cameras, Senrio reported this week. The firm found the flaw in a security camera developed by Axis Communications, one of the world's biggest manufacturers of the devices. The Model 3004 security camera is used for security at the Los Angeles International Airport and other places, according to Senrio. The problem turned out to be a stack buffer overflow vulnerability, which the firm dubbed "Devil's Ivy."
