According to "DHS Emergency Directive Regarding DNS Tampering" which published above and its IOCs included in the following cert alert(https://www.us-cert.gov/ncas/alerts/AA19-024A). We found another indicators related to communications initiated in Nov 1,2018. This old communication from 2 months ago from internal users directly to url: http://www.googleg.com which direct user to another URL: http://ww1.googloe.com. Both of these domains hosted on suspicious server which contains several malicious other domains like: [bingo.sg, adult.sg, asus.com.sg, bank.com.sg]. This server was reversed to several IP addresses:
107.161.23.204 ,192.161.187.200,209.141.38.71, 199.59.242.151.

198.133.158.0/23 -> where the email for the domain (googleg.com) goes which distributed malicious files: ec40ccaad63f8855d8de31a42b7c67ac.exe according to multiple analyzers on virustotal from month ago.

Sample of file names: hcjgfcyz.exe, idkhgdza.exe, xtntzbtk.exe, qqpvgube.exe. although the last file name was from month ago, the first file is NEW file used in this communication.

Analysis: .exe files that will create new exe file (random.exe) under Temp\, create new folder under windows under system32 (random-name) which will use it later to move the exe file in Temp to this place under “random-name”, then create service (using sc.exe utility) for “random-name.exe” with name “WIFI Support” that will auto-start to pretend as internet WIFI connection support service and you can know the following that could happen using this service specially with C2 server domain (107.161.23.204) and other communicated identities: 43.231.4.7, 5.9.32.166, 144.76.199.43, 144.76.199.2, 85.25.119.25, 46.4.52.109, 176.111.49.43, 216.58.215.68 on different ports (80, 425, 481, 443).
