Threat Intelligence Briefing

The threat landscape saw a 23.3% surge in malicious activity in the last 6 hours, dominated by SSH brute-force attacks. The bulk of activity originated from Romania (RO), India (IN), Russia (RU), and the United States (US). Within the Nordic region, Sweden (SE) saw a single SSH brute-force attack. No significant abuse of specific hosting providers was observed, and Tor exit node activity remained minimal. The majority of attacks appear to be originating from compromised residential IPs, given the diverse geographic distribution. Defenders should prioritize monitoring networks in RO, IN, RU, and US for SSH brute-force attempts. Specifically, monitor IPs 45.135.232.92 (RU), 167.71.231.200 (IN), and 45.140.17.124 (RU). Consider implementing rate limiting and strong password policies to mitigate the brute-force threat. Continue tracking the overall increase in malicious activity for further trends, especially if it continues.
