Threat Intelligence Briefing

Threat volume surged 400% compared to the previous 6-hour period, with 16,188 total threats representing a significant deviation from typical baseline activity. This spike is primarily driven by spam (4,972 events) and attacks (4,132 events), indicating coordinated campaign activity rather than routine background noise. Nordic countries show elevated but proportional activity, with Sweden (56 threats) and Finland (48 threats) experiencing increased scanning and brute-force attempts consistent with global patterns. The top threat actors originate from US (2,531), India (1,142), and China (995) IPs, with specific clusters targeting SSH services. Focus on blocking patterns rather than individual IPs: implement temporary rate-limiting for SSH connections from ASNs demonstrating repeated brute-force behavior, particularly from Russian and Bulgarian networks. Prioritize investigation of spam campaigns which show the highest volume increase.
