Weird routing pattern - Atlanta device hitting Argentine ISP + unknown EU endpoint

Hey NANOG,

Seeing some odd routing from an Atlanta device that seems to lack logic to say the least. Thought I'd shed some light 
on it....

Expected: Apple infrastructure (17.x.x.x) Actual destinations: - 109.1.2.1 (SFR France, INFRA-SBT, abuse () gaoland 
net) - 200.3.10.2 (INTERWEB-DAIREAUX Argentina, 200.3.10.0/23) - 67.1.2.1 (CenturyLink) - 184.0.0.13 (CenturyLink) - 
136.3.5.1 (AWS) Pattern: TLS 1.3, 02:00-03:30 local, multiple clients Geographic spread makes no sense (EU + small 
Argentine ISP from US). Possible C2/exfil. Worth checking your flows for 109.1.0.0/17 and 200.3.10.0/23 from 
non-EU/LACNIC sources. - Joseph II
