Threat Intelligence Briefing

Global threat activity increased by +3.3% compared to the previous 6-hour period, consistent with the 7-day average and within normal fluctuation range. Reconnaissance remains dominant (93% of all events), primarily from known scanning clusters in the US, CN, and DE. No new campaigns detected; top IPs are linked to Microsoft Azure (IN, JP) and Romanian hosting, showing multi-vector scanning patterns. Nordic exposure is stable, with SE and FI reporting expected levels of CMS and SSH brute-force attempts. Activity in NO and DK remains minimal and aligned with baseline. Consider temporary blocking or rate-limiting /24 ranges associated with high-reporting ASNs like Microsoft Corporation and Unmanaged Ltd, particularly for IPs exhibiting web_scanner and bruteforce behavior. Deprioritize isolated residential IPs with single reports—these reflect background noise. Focus on pattern-based detection of multi-category IPs from datacenter networks, as these show coordinated scanning rather than opportunistic probes.
