Threat Intelligence Briefing

Global threat activity increased by 9.2% compared to the previous 6-hour period, primarily driven by reconnaissance scans, which remain consistent with the 7-day average in pattern but elevated in volume. The US and China continue to dominate source geography, with Google LLC and Microsoft Corporation among the top contributing ASNs. Nordic countries show stable baselines, with Sweden reporting the highest regional volume (575 events), mainly reconnaissance and brute-force attempts. No new persistent campaigns detected; observed activity aligns with ongoing automated scanning. Consider temporary blocking or rate-limiting for recurring IP clusters from DigitalOcean and Alibaba, particularly those associated with SSH brute-force patterns. Deprioritize isolated events from residential ISPs unless part of broader clusters. Focus monitoring on repeat offenders in datacenter ranges rather than ephemeral IPs, as infrastructure-based patterns indicate coordinated scanning rather than random noise.
