Threat Intelligence Briefing

The threat landscape has intensified, showing a 28.7% increase in malicious activity compared to the previous 6-hour period. The majority of threats continue to be focused on SSH brute-force attacks, accounting for 95% of the total. Within the Nordic region, Sweden experienced 4 attacks primarily categorized as repeat offending and SSH brute-forcing, while Finland saw 3 attacks, all attributed to SSH brute-force attempts. No significant activity was observed originating from or targeting specific ISPs or hosting providers during this period. Given the surge in SSH brute-force activity, prioritize monitoring networks and ASNs originating from Russia (RU), particularly those exhibiting brute-force behavior. Track IPs `45.135.232.92`, `45.140.17.124`, and `45.135.232.177`, which are repeat offenders. Defenders should implement stricter SSH access controls and consider rate-limiting connections from known malicious sources.
