Threat Intelligence shows malicious traffic coming from Palo Alto subnets

Vladimir_S — Wed, 30 Aug 2023 09:07:00 GMT

Hello All,

Recently, we started seeing threat events from different Palo Alto IPs (example subnet 198.235.x.x).

When we check them in AbuseIPDB, they show up as 100% malicious:

https://www.abuseipdb.com/check/198.235.24.146

Microsoft TI also categorizes them as malicious, but not the PA FWs.

Does anyone know what these subnets are used for or why they show up as malicious?

Attaching one of the logs.

Thanks in advance,

Pavel
