The spy tool that the US government ordered Yahoo to install on its systems last year at the behest of the NSA or the FBI was a “poorly designed” and “buggy” piece of malware, according to two sources closely familiar with the matter, reports Motherboard. From the article: Last year, the US government served Yahoo with a secret order, asking the company to search within its users’ emails for some targeted information, as first reported by Reuters this week. It’s still unclear what was the information sought, but The New York Times, citing an anonymous official source, later reported that the government was looking for a specific digital “signature” of a “communications method used by a state-sponsored, foreign terrorist organization.” Anonymous sources told The Times that the tool was nothing more than a modified version of Yahoo’s existing scanning system, which searches all email for malware, spam and images of child pornography.
