Threat Intelligence Briefing

Threat Landscape Right Now: Observed threat activity decreased 23.2% compared to the prior 6-hour window, with a focus on SSH brute-force attacks (92% of total events). Compromised or residential IPs are the primary attack vector. Within the Nordic region, Sweden experienced limited activity, with 2 unique IPs involved in SSH brute-force attempts. No specific hosting providers or ISPs exhibit disproportionate malicious activity. No Tor exit node abuse was detected. Tactical Intelligence: Monitor ASNs associated with the top attacking countries (RU, RO, CN, US, IR) for continued SSH brute-force activity. Prioritize detection rules for SSH login failures and unusual traffic patterns. Given the concentrated nature of SSH attacks, consider implementing rate limiting and strong password policies. Continue tracking the top attacking IPs, particularly 45.135.232.177, 45.140.17.124, and 194.0.234.19.
