Threat Intelligence Briefing

Threat volume decreased significantly by 63.8% compared to the previous 6-hour period, dropping from 290,627 to 105,246 events. This represents a substantial deviation from the recent high-volume pattern, though reconnaissance remains the dominant category (101,103 events). Nordic countries show consistent patterns: Sweden leads with 703 events primarily from blacklisted sources and reconnaissance, while Norway's 200 events are reconnaissance-focused. The top threat IPs originate from Vietnam and Romania, showing concentrated SSH brute-force and attack patterns rather than distributed campaigns. Focus monitoring on Vietnamese and Romanian ASN ranges showing repeated SSH brute-force patterns rather than individual IPs. Consider temporary blocking of /24 ranges from these regions if SSH attacks align with your infrastructure. Prioritize investigating reconnaissance patterns from Swedish sources as they represent the most consistent regional threat.
