Roundup Highlight: SLOTHFULMEDIA RAT and Ryuk

20201116A: Suspicious Domains Registered Through NameCheap and Hosted at FranTech


In this Roundup, we highlight Incident 20201116A: Suspicious Domains Registered Through NameCheap and Hosted at FranTech. ThreatConnect Research identified a set of domains registered through NameCheap on 11/13/20 at essentially the same time and hosted on probable dedicated servers in FranTech ISP IP space. This combination of registration and hosting has also been seen in recent sets of Ryuk / Wizard Spider / UNC1878 registrations; however, it is not unique to them and at this time we cannot confidently assess that this infrastructure is associated with Ryuk. Notably, the domain name strings are inconsistent with those in previously identified Ryuk sets, no SSL certificates have been seen, and no related malicious files could be identified. Future reuse of these domain strings or additional information on related SSL certificates and files would help determine whether this infrastructure is related to Ryuk.

The identified domains and their hosting IPs include the following:

beerpong101[.]com (205.185.114[.]25)

growtancy[.]com (209.141.49[.]12)

ThreatConnect Research Team Intelligence: Items recently created or updated in the ThreatConnect Common Community by our Research Team.

  • 20201116B: APT35 Domain cover-home-panel[.]xyz ThreatConnect Research identified a most likely APT35 / Phosphorus / Charming Kitten domain registered through OnlineNIC Inc. on 11/15/20 and hosted on a dedicated server at a Hetzner IP. Per, this domain currently redirects to China Central Television’s domain. The domain’s registration and hosting characteristics are consistent with previously identified APT35 infrastructure. At this time we have no additional information on the extent to which this domain has been used maliciously.
  • 20201118A: Possible CloudAtlas Infrastructure ThreatConnect Research reviewed recently identified CloudAtlas / RedOctober files and related infrastructure. Based on domain reseller, string, and/or email domain reuse, we have identified several other domains and hosting IPs that also possibly are associated with CloudAtlas.
