Threat Intelligence Briefing

Threat activity has decreased significantly, down 65.4% from the previous 6-hour period. The vast majority of malicious activity (97%) consists of SSH brute-force attacks originating primarily from the US, Romania, China, and Russia. No significant malicious activity was observed within Nordic countries. No particular hosting providers or ISPs stand out as being disproportionately targeted or abused. The lack of Tor exit node activity suggests threat actors are utilizing more direct attack vectors. Given the prevalence of SSH brute-force attempts, prioritize monitoring networks exhibiting similar behavior. Specifically, monitor the ASNs associated with IPs 45.135.232.92 (RU), 2.57.121.112 (RO), 192.154.248.9 (US), 165.232.178.62 (IN), and 197.136.141.15 (KE). Consider implementing rate limiting and strong password policies to mitigate this threat. Track any shifts toward application-layer attacks, as the current focus is heavily on network-level brute-forcing.
