Threat Intelligence Briefing

Global threat volume decreased significantly by 87.7% compared to the previous period, representing a major deviation from the typical high baseline. This sharp decline is unusual and suggests potential attacker shift to off-hours or temporary infrastructure disruption. Nordic regions show routine low-level activity: Sweden (26 events), Finland (6), and Norway (4) primarily face SSH brute-force and repeat offender attacks, consistent with their 7-day averages. The top threat IPs originate from Bulgaria, Turkmenistan, and UK networks, focusing on SSH compromise. Focus defensive actions on monitoring SSH authentication patterns rather than blocking individual IPs, as these are ephemeral. Consider temporarily rate-limiting SSH connections from ASNs hosting repeat offenders, particularly those in Eastern European ranges. This low-volume period allows for security rule tuning and log review, but maintain vigilance for normalized threat resurgence.
