CISA mixup of IOC domains

Google's Threat Intelligence Group (GTIG) and Mandiant's recent Disrupting the GRIDTIDE Global Cyber Espionage Campaign report is great and it has lots of good Indicators of Compromise (IOC). Many of these IOCs had already been shared by CISA in May last year as part of their Alert AA25-141A titled "Russian GRU Targeting Western Logistics Entities and Technology Companies". The IOC overlap between these two reports is surprisingly big, provided that the GTIG report covers a Chinese espionage group while the CISA report covers the Russian GRU unit 26165 (aka APT28 / Fancy Bear).

But some of the domain names in CISA's report from last year seemed strange. For example, the domain name "accesscan[.]org" doesn't seem to ever have been registered. The GTIG report, however, contains the very similar domain "accesscam[.]org". This accesscam domain is registered to the dynamic DNS provider Dynu Systems, whose services are often abused by malicious actors. Is it possible that there are typos in the IOCs published by CISA? I think so.

Another odd domain in CISA's AA25-141A is "glize[.]com", which I suspect is a typo from either "giize[.]com" or "gleeze[.]com". The two latter domains are listed in the GTIG report and both of them also belong to the dynamic DNS provider Dynu Systems. The domain listed in CISA's alert, on the other hand, appears to be a legit website (archived page from 2024) from the marketing company Glize in Malta.

Glize's website seems to have disappeared sometime in 2025.
