Phishing PDF Received in my ISC Mailbox
I received several PDF like these in the past few days in my ISC mailbox and decided to look at 3 that were very similar. All 3 files are a one page picture with nothing else in it except a URL.
Looking at the first one using Didier's pdfid.py tool:
There is something interesting in all 3 of them, they all have a URL (/URI) embedded in them. Using pdf-parser.py, lets extract the URLs:
PDF 1
.PNG)
PDF 2
PDF 3
What is interesting about all 3 email is they all have the same behavior with the same location /a/. The first 2 URLs do not resolve, only aleksalekss[.]ru resolve to 80.66.78.78 which was recently activated on the 28 March 2022. Several files have been submitted to VirusTotal in the past 4 days with 0 to low detection[1]. None of the 3 files below had any matches (submissions) in VirusTotal.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
