Atkin added that the robbery has been a "huge wake-up call for me with social media," adding, "We need to be very careful about geotagged locations ... And posting live, so that people know your whereabouts."
"No matter who you are, you just need to be very cautious," she advised. "And I just hope and pray that everybody is safe... I don't want bad people to take our joy away from us, and our ability to live."
Meanwhile, a source close to Kim -- who reunited with her family in New York City on Monday -- tells ET she is "absolutely traumatized" after the terrifying incident.
"When the incident happened, [Kim] was half asleep and was woken up so abruptly," the source adds. "She picked up her cell but wasn't able to call [bodyguard] Pascal [Duvier] in time before one of the guys grabbed it out of her hand and she realized what was happening. It was absolutely horrific."
Kim also "didn't get a good look at any of the guys' faces," according to the source. "None of them spoke English, so she couldn't communicate with them ... All she kept saying over and over is 'I have kids. Take anything you want. Please don't kill me. Please don't kill me.'"
