Version: 1.0



APT1 hijacked FQDNs associated with legitimate websites hosted by hop points. Mandiant considers them to be "hijacked" since they were originally registered for a legitimate reason but are used by APT1 for malicious purposes.[2]


Detectable by Common Defenses (Yes/No/Partial): No

Explanation: Generally not easily detectable unless domain registrar provides alerting on any updates.

Difficulty for the Adversary

Easy for the Adversary (Yes/No): Yes

Explanation: Requires adversary to gain access to an email account for person listed as the domain registrar/POC. The adversary can then claim that they forgot their password in order to make changes to the domain registration. Other possibilities include social engineering a domain registration help desk to gain access to an account or take advantage of renewal process gaps.
