Threat Intelligence Briefing

Threat Landscape Right Now: Observed threat activity decreased 14.9% globally compared to the prior six-hour period. SSH brute-force attempts dominate, accounting for 99.5% of all detected threats. Limited activity was observed in the Nordic region, with a single Finnish IP address involved in SSH brute-forcing. The majority of attacking IPs originate from Romania and Russia. No significant abuse of major hosting providers or Tor exit nodes was detected. Infrastructure appears to be largely datacenter-based, though further investigation is needed. Tactical Intelligence: Monitor ASNs associated with the top attacking countries, specifically RO and RU, for increased SSH activity. Focus on hardening SSH configurations and consider rate-limiting connections. Investigate the single Finnish IP for potential compromise. Although no CERT-EU advisories exist, continue monitoring for emerging threats targeting SSH services and any changes in attack patterns.
