Roundup Highlight: Recent Probable Charming Kitten Infrastructure

20200803B: Microsoft Phosphorus Sinkhole Domain Siblings

 

Our highlight in this Roundup is Incident 20200803B: Microsoft Phosphorus Sinkhole Domain Siblings. ThreatConnect Research reviewed the following domains (and the notable IPs that previously hosted them) that began resolving to Microsoft’s Phosphorus sinkhole in late July 2020:

googel.email

app-view-support.club (5.9.162.156)

g-shorturl.com

on-dr.com

mailerdaemon.me (138.201.102.239)

mail-instgram.com (51.91.200.193)

verifychecking.com (148.251.85.50)

support-myservice.com (148.251.85.50)

cmailco.xyz (148.251.85.50)

We identified several additional domains that probably are related to Phosphorus / APT35 / Charming Kitten based on co-locations with the aforementioned domains on likely dedicated servers. The relevant IPs, the additional domains, and other notable IPs hosting those domains include the following:

148.251.85.50

email-checker.xyz

5.9.162.156

view-external-page.best (5.9.162.157, 88.99.10.237, 88.99.10.236, 88.99.10.235)

support-following-page.club

support-viewing-page.club

page-support-view.club

name-file-support.best (5.9.162.157)

Finally, we reviewed those additional, likely dedicated IPs identified from the hosting history for the co-located domains. This identified another set of domains that probably are associated with Phosphorus based on those co-locations and naming convention reuse:

88.99.10.237

reload-cover-page.live

reload-page-cover.site

88.99.10.236

cover-home-page.site
