The Shadow Brokers are back, this time with files they claim are "NSA passwords." The group resurfaced after punitive US airstrikes hit Syrian targets in response to the Assad regime's use of chemical weapons against mostly civilian targets. The Shadow Brokers have unpleasant things to say about US President Trump, saying in their communiqué (with familiar scriptwriter's broken English) that they're "no longer" his supporters, that he's abandoned "his base." So President Trump has either fallen out of favor with the Shadow Brokers' (by consensus Russian) masters or that he was never in that much favor to begin with. Motherboard, often in communication with the Brokers, has asked for clarification, but received none.
