Yesterday, Bullet Proof Hosting provider sclad{.}us aka Morningstars (AS215939) connected to UAC-0050 (CERT-UA#8453 and CERT-UA#8494 Alerts) announced "technical works" as their main upstream drop them.

One month after the release of our Doppelganger investigation and the shutdown of Aeza at Datacamp, the ASNs that made it to the finish line have migrated to @packetbouncer @aurologiccom and @RoyaleHostingBV @stanvandeklippe Many prefixes remain behind GRE tunnels.

The power of CSI (194.36.177{.}229) server of 1cent{.}host runs in AS210281. Can you figure out where do the GRE tunnels of this BPH terminate? @banthisguy9349

MTU1448 update: Doppelganger Prefix sneaking away from Aurologic upstream to AS214891. Prefix now using AS56630 Melbikomas (LT) as upstream in Germany. route: 77.91.66.0/24 origin: AS214891 mnt-by: CENTHOST-MNT last-modified: 2024-08-02T09:47:27Z

The answer is 1448. In a standard setup the maximum payload for a ICMP packet will be 1472 bytes (1500-20-8). 28 bytes for the IP (20) and ICMP (8) headers. If you run GRE tunnels, you need to account for a 24 extra bytes overhead for Outer IP(20) and GRE(4). 1500-20-8-20-4=1448

Yesterday, AS198981 (netshield/1centhost) continued to serve Doppelganger domains but this time with @packetbouncer (Aurologic) as upstreams. This is not the kind of blocking we were expecting from you.

Suspended Cyberhub ASN that is part of the Doppelganger ecosystem has been just renamed to HellaAS (Hellenic Digital Services Ltd / Luxhost). Seems like "luxhost" is the new Aeza bullet proof hoster. 🤦 @Gi7w0rm @banthisguy9349 @SourcesOuvertes

In a new twist in the saga of Doppelganger, Aeza has decided to stop providing connectivity to two bullet proof hosters: Lethost and Sunhost. What a nice way to show the world that they handle "abuse". (1/3)

Since the release of our forensic investigation about Doppelganger infrastructure there has been a few interesting developments. Once of them is that the F-domains @ TNSECURITY and NETSHIELD remain online thanks to one common upstream provider: Datacamp/CDN77

BildBild

It seems that TNSECURITY/EVILEMPIRE is no longer routing traffic from Germany. Nice to have now a much clear picture of where Lethost is coming from

Hostinger today, DNS parking the F domains of DG. bikerspace[.]shop btwidea[.]shop cscerbr[.]shop envhb[.]shop summitslope[.]shop vokei[.]shop

TNSecurity (aka Evilempire) is interesting for 4 things: - Runs from Germany as downstream of @packetbouncer - Runs front proxies for Doppelganger - It is a hotspot of malware distribution - It was a "dorector" @Gi7w0rm @ffforward @banthisguy9349

Let us check of few domains of DG campaign today that were registered with Namecheap and then moved to Hostinger DNS parking service. The service has been provided for months and tje domains have been pointed to: AS215428 Mykyta Skorobohatko RU AS216309 Tnsecurity Ltd RU

Bild

Just a couple of hours ago, all these domains has been used by Doppelganger. All controlled from: - Hostinger DNS Parking service and - Served from "Evilempire" downstream of Aurologic in Germany.
