Threat Intelligence Briefing

Observed threat activity increased 40% in the last 6 hours, driven primarily by malware command and control (C2) and SSH brute-force attacks. Globally, the majority of observed attacks originated from Russia, Netherlands and Romania. One SSH brute-force attack was observed emanating from Sweden. No significant abuse was observed tied to specific ISPs or hosting providers. The majority of top attacking IPs are not resolving to specific countries, indicating potential obfuscation or compromised infrastructure in transit networks. No Tor exit node abuse was observed. Given the surge in C2 and brute-force attempts, prioritize monitoring network traffic to/from ASNs associated with Russia, Netherlands, and Romania. Investigate the non-attributing IPs for malicious activity. Focus on detecting malware beaconing and anomalous SSH login attempts. The increase in overall threat volume warrants heightened alert review and proactive threat hunting.
