The US is no stranger to hacking North Korea, but it's usually in a bid to directly thwart the country's military ambitions. Now, however, those attacks are being used as a diplomatic strategy. The Washington Post has learned that President Trump ordered a broad pressure campaign against North Korea that led to the US conducting a denial of service attack against North Korea's spying office, the Reconnaissance General Bureau. The move flooded the RGB's servers with traffic that effectively strangled their internet access, including the Bureau 121 group responsible for the North's hacking campaigns. And while it clearly didn't change Kim Jong Un's mind, it does appear to have had a practical effect.
