Threat Intelligence Briefing

Threat Landscape Right Now: Observed threat volume has decreased significantly, down 73% compared to the previous six-hour period. The vast majority of malicious activity (99%) is focused on SSH brute-force attacks. Top originating countries include Romania, India, and Russia. We are seeing no notable malicious activity originating from or targeting Nordic countries. There are no specific ISPs or hosting providers experiencing disproportionate abuse at this time, and Tor exit node activity is negligible. Tactical Intelligence: Monitor ASNs associated with the top attacking countries, particularly those hosting infrastructure known for SSH brute-force activity. Prioritize detection rules for SSH login failures and unusual authentication patterns. The dramatic decrease in overall volume warrants investigation to determine the cause – potential shifts in attacker tactics or effectiveness of existing defenses. Continue monitoring for any resurgence in CMS attacks, although currently minimal.
