Scary stuff.
It's been a rough week for the Jenner clan.
A woman was arrested by FBI special agents on Thursday in Newark, California, on federal cyberstalking and hacking charges related to harassment and threats targeting Kris Jenner.
Christina Elizabeth Bankston was arrested on 15 counts for allegedly harassing Jenner, members of her family, and two of her assistants. According to court documents obtained by ET, Bankston sent hundreds of disturbing emails and anonymous text messages to 60-year-old Jenner from multiple telephone numbers between March and September 2014.

Bankston is also accused of impersonating Jenner during text messages to the reality star's family by hacking into her iCloud account, including her ex, Caitlyn Jenner, and one of her daughters, who the documents note was a minor at the time.
And the alleged harassment didn't stop there. The 36-year-old nurse's assistant also allegedly hacked into Jenner's Instagram account and posted "negative comments" about "blacks" and other "disparaging remarks." She also allegedly called the Los Angeles Sheriff's Department in April 2014 and falsely stated that there was a suicide attempt at the residence, prompting them to send emergency personnel to Jenner's home -- commonly known as swatting.
Bankston appeared in federal court on Friday in Oakland, and was released on $20,000 bond. She must appear in court again on Aug. 22, and is not allowed to contact Jenner.
The arrest comes after Jenner's daughter, 20-year-old Kendall, was also granted a restraining order against an alleged stalker on Thursday. Shavaughn McKenzie, 25, has pleaded not guilty to two misdemeanor charges of stalking and trespassing.
