Threat Intelligence Briefing

The global threat landscape shows a 62.9% decrease in reported threats compared to the previous six-hour period. SSH brute-force attacks account for 53% of malicious activity, followed by malware C2 communications at 46%. Observed Nordic activity is minimal, with a single SSH brute-force attack originating from Sweden. No significant abuse of specific ISPs or hosting providers was detected, and no Tor exit node activity was reported. The majority of attacks appear to be originating from compromised datacentre IPs, given the prevalence of SSH brute-forcing. Given the dominance of SSH brute-force attempts, prioritize monitoring networks and ASNs associated with known brute-forcing activity, particularly those originating from Russia (RU). Continue to monitor for changes in attack patterns, specifically a potential shift from SSH brute-force to malware distribution, which could indicate a change in attacker objectives. Consider implementing stricter SSH access controls and monitoring.
