The attached file is named ScannedDocs122151.xls which comes in at least five different versions (VirusTotal results [1] [2] [3] [4] [5]). The Malwr reports for these documents [6] [7] [8] [9] [10] show the malicious macro contained within downloading a malware executable from:

armandosofsalem.com/l9k7hg4/b4387kfd.exe
trinity.ad-ventures.es/l9k7hg4/b4387kfd.exe
188.226.152.172/l9k7hg4/b4387kfd.exe

This dropped binary has a detection rate of 4/55. It is unclear what this does as in the Malwr report it throws an error. The payload is almost definitely the Dridex banking trojan, and even if this version is faulty then it is likely that the malware will be fixed shortly.
