Threat Intelligence Briefing

Threat volume surged by several orders of magnitude (2,995 → 33,308 events) compared to the previous period, representing a severe deviation from baseline. This spike is primarily driven by spam (8,500 events), attacks (7,577), and malware C2 (6,855), indicating coordinated activity rather than routine noise. The US (2,819), Brazil (2,040), and India (1,737) are top sources, with Nordic countries showing stable but persistent scanning and brute-force attempts. Focus on blocking ASNs associated with these top-source countries rather than individual IPs, which are ephemeral. Prioritize investigating malware C2 clusters and spam campaigns, as these represent the most significant volume increases and potential infiltration risk.
