Threat Intelligence Briefing

Threat Landscape Right Now: Observed global threat activity decreased 18.6% compared to the previous six-hour period. SSH brute-force attacks constitute 99% of observed malicious activity, with a single HTTP DDoS attack detected. Iceland experienced limited activity, with 1 SSH brute-force attack originating from a unique IP. Russian and Romanian IPs are heavily represented among the top attacking IPs, suggesting potential botnet or compromised server infrastructure. No significant abuse of known hosting providers or Tor exit nodes was detected. Tactical Intelligence: Monitor ASNs originating from Russia (RU) and Romania (RO) for continued SSH brute-force activity. Focus on detecting and mitigating credential stuffing attacks targeting SSH services. Investigate the infrastructure behind IPs 45.134.26.79, 45.135.232.177, and 193.46.255.244 due to their high attack counts. Given the prevalence of SSH brute-forcing, ensure robust password policies and consider implementing multi-factor authentication.
