Threat Intelligence Briefing

Global threat activity increased by 21.6% compared to the prior 6-hour period, driven primarily by a rise in reconnaissance and malware C2 traffic. This deviation from the recent baseline is notable, with consistent volume across major datacenter providers—particularly Google LLC and DigitalOcean, LLC—indicating potential campaign coordination. Nordic countries remain within expected thresholds, though SE and FI show persistent targeting across attack, brute force, and malware C2 vectors, consistent with ongoing regional exposure. The top individual IPs are linked to long-standing malicious infrastructure, with several observed over multiple weeks. Consider temporary blocking or rate-limiting at the ASN level for Google and DigitalOcean ranges exhibiting clustered malware C2 behavior. Prioritize pattern-based detection over single-IP blocks, as threat sources are distributed and infrastructure is reused. Deprioritize isolated spam and scanning events from residential ISPs, as these align with routine background noise rather than targeted campaigns.
