Quick post for today. I have been seeing a lot of malspam with malicious Javascript attachments zipped inside a 7zip archive for the past couple of days. The emails themselves all seem to revolve around the theme of a receipt or invoice as seen below. From what I can tell,…
So continuing from my update yesterday (see 2017-08-30 Trickbot Maldoc – Part One), it looks as if sometime last night while working on the writeup, and perhaps again this morning, Trickbot got cheeky and updated itself. It looks as if the file “Atpsijj.exe” is a new file with a different…
For today’s post, I will be looking at a malicious Word document that we got spoofing NatWest which led to Trickbot malware being installed on the system. After I found this sample, I started to see posts on Tweeter from people like @dvk01uk and @VK_Intel posting about Trickbot. For this…
For today’s post, I am walking through an Emotet malspam that we received this past Friday that contained a simple link that lead to a macro enabled Word document. Googling around I see that @dvk01uk came across the same URLs 5 days ago. You can read that post here. Running…

This write up stems from a user getting a malicious Word document via an email for an invoice. Running the PCAP file through Network Total, I saw that that this was tagged as Geodo/Emotet malware. Googling around for Emotet, I came across a Forcepoint article in which they did a…
Looking for some malspam yesterday and I came across something that looks like it was exploiting the CVE 2017-0199 vulnerability in MS Office RTF files. FireEye did a nice write-up of this which you can read here. Googling to see if anyone else had seen these domains before, I was…
So last week I came across some malspam that used a PDF with an embedded Word document in it that encrypted my test VM with Jaff ransomware which I discussed here. Trying to figure out how the script worked, I came across some aspects/things that I had not seen done…
So yesterday I came across some malspam that used a PDF with an embedded Word document in it that encrypted my test VM with the Jaff ransomeware. It looks like Brad (@Malware_Traffic) received something very similar to me which you can read about here. As a side note, I did…
