This article is a result of an initial investigation, no attribution is done but you\u00e2\u20ac\u2122ll have all the necessary info for a deeper investigation.\r\nThe malicious document has SHA256: 5D9E1F4DAB6929BC699BA7E5C4FD09F2BBFD6B59D04CEFD8F4BF06710E684A5E.\r\n\r\nAfter a first glance I thought to know what\u00e2\u20ac\u2122s behind the rft, but running a specific script I got disappointed by the result. For a quick response, a submission to a sandbox could be the best option you have, but you\u00e2\u20ac\u2122ll miss all the fun! I decided to manually check using an hex editor because it\u00e2\u20ac\u2122s incredible how you can extract objects in a fast way."
