Threat Intelligence Briefing

Threat Landscape Right Now: Observed threat activity decreased sharply by 62.9% compared to the previous six-hour window. The vast majority of attacks continue to be SSH brute-force attempts. Limited Nordic activity was detected, with two unique IPs in Sweden engaging in SSH brute-forcing. No significant abuse of specific hosting providers or Tor exit nodes was observed during this period, and the attack infrastructure appears to be distributed without a clear focus on datacenter or residential IPs. Tactical Intelligence: Monitor the networks associated with the top attacking IPs, particularly 45.135.232.0/24 (RU) and 2.57.121.0/24 (RO), given their continued SSH brute-force activity. Although overall volume is down, the persistence of SSH attacks warrants continued vigilance. Track emerging brute-force techniques and ensure systems are patched against common vulnerabilities.
