Threat Intelligence Briefing

Observed threat activity increased 29% in the last 6 hours, driven primarily by SSH brute-force attacks. While the global distribution is broad, the majority of attacks originated from infrastructure in China, Romania, and Russia. Nordic countries saw minimal activity, with single SSH brute-force attempts originating from unique IPs in both Finland and Sweden. No significant Tor exit node activity was detected, and no specific ISPs or hosting providers stand out as disproportionately targeted or abused during this period. Given the concentration of brute-force attempts, prioritize monitoring networks within the originating countries, specifically ASNs associated with known hosting providers. Focus on detecting and mitigating credential stuffing attacks and unusual login patterns. While Nordic activity is low, maintaining awareness of SSH traffic originating from those regions is advised. Track Russian IP ranges `45.135.232.0/24` and `45.140.17.0/24` due to high brute-force attempt volume.
