Threat Intelligence Briefing

Global threat volume decreased significantly by 63.1% compared to the previous period, with 1,225 events representing a return to baseline levels after heightened activity. This is consistent with routine weekend evening patterns across European and US business hours. SSH brute force remains the dominant attack vector, with clusters from Romanian (ASN 9049, 2.57.122.0/24) and Russian (ASN 48347, 176.120.22.0/24) networks showing persistent, coordinated activity. Nordic activity remains stable with Sweden seeing 16 events primarily in attacks and SSH brute force, consistent with its 7-day average. Recommend maintaining existing rate-limiting rules for SSH traffic, particularly from Eastern European ASNs exhibiting repeated scanning patterns. No immediate blocking is required given the routine nature of this traffic. Focus monitoring on the continued SSH brute force campaign rather than individual IPs.
