That isn't WannaCry, it clearly says so in the article.
No, it doesn't use the same vulnerability either. Microsoft had to release new patches. https://www.axios.com/global-hack-appea ... 55293.html
Keep in mind this is probably just the start of a continued string of hacks we will be seeing for some time. The leaked NSA toolkit from a few months ago had all all sorts of unpublished vulnerabilities and tools, and Eternal Blue (the attack vector for Win 7 systems that WannaCry exploited) is just one of many that were probably in that kit. For those that don't know, Eternal Blue exploited a vulnerability in Win 7 that the NSA discovered but never notified Microsoft about. It allowed remote attacks on Win 7 installs without the need for user interaction in any fashion.
