Threat Intelligence Briefing

Global threat volume decreased by 2.5% compared to the previous period, remaining consistent with the 7-day average and representing routine background noise. A notable cluster of SSH brute force attacks originated from the Polish ASN hosting 87.251.64.144/29, with four IPs from this /24 subnet appearing in the top threats. Nordic traffic patterns were stable; Sweden and Finland saw the highest volume, primarily from abuseipdb_blacklist and reconnaissance, which aligns with their typical baseline activity. No new campaigns emerged. Focus defensive actions on the persistent SSH brute force cluster from the Polish ASN 87.251.64.144/29. Consider implementing temporary blocking or rate-limiting for this specific CIDR range, as these IPs are part of a coordinated attack pattern. Routine reconnaissance from the US and China can be deprioritized as it represents expected background scanning traffic.
