After last week’s Baltimore riots, the hashtag #BALTIMORELOOTCREW began to appear on Twitter and other social media linking together posts that depicted pilfered prescription drugs and demolished store shelves. The Baltimore Sun says that “crew” was not actually in Baltimore protesting the death of Freddie Gray. Many photos shared using that label, and others, were taken years ago, and often not even in the U.S., said Baltimore cybersecurity firm ZeroFox. Bad actors and so-called “hacktivists” descended on Baltimore electronically, flooding social media with automated accounts and inauthentic images, said ZeroFox’ James Foster. Law enforcement and cybersecurity experts said such barrages increasingly target areas of unrest around the world, spurring violence and challenging efforts to contain it.
