Less than an hour after tweeting about being safe during an active shooting at YouTube's headquarters, Vadim Lavrusik's account was hit by hackers. 

Lavrusik, a product manager at YouTube, sent one of the first tweets out about an active shooting at the office in San Bruno, California, at 12:57 p.m PT. The first 911 call for the shooting had come in at 12:46 p.m. PT, and police arrived in two minutes, San Bruno Police Chief Ed Barberini said at a press conference on Tuesday.
