Threat Intelligence Briefing

Threat Landscape Right Now: Observed threat activity decreased 99.9% compared to the previous 6-hour window, with a total of 238 threats originating from 169 unique IPs. SSH brute-force attempts constitute the vast majority of attacks. Within the Nordic region, Sweden saw minimal activity, with 2 brute-force attacks originating from 2 unique IPs. Most prevalent attacking IPs geolocate to Russia, with secondary concentrations in China and Romania. There were no significant spikes in malicious activity associated with specific ISPs or TOR exit nodes. Tactical Intelligence: Focus monitoring on ASNs associated with observed Russian, Chinese, and Romanian IPs, specifically targeting SSH brute-force activity. Monitor for changes in attack patterns that might indicate reconnaissance or lateral movement attempts. Due to the overwhelming prevalence of SSH brute-force, ensure default credentials are changed and multi-factor authentication is enabled where possible.
