121.199.166.76 has a threat confidence score of 83%. This IP address from China (AS37963, Hangzhou Alibaba Advertising Co.,Ltd.) has been observed in 8 honeypot sessions targeting REDIS protocols. Detected attack patterns include redis cron persistence multi variant payload. First observed on March 15, 2026, most recently active March 16, 2026.
Detects Redis configuration abuse where an exposed instance is reconfigured to write cron entries that execute remote payloads via curl or wget/variant binaries (including root-executed variants), followed by SAVE to persist the malicious cron file to disk. Covers multiple backup job names and pipe-to-shell download techniques used for automated persistence and recurring remote code execution.
Identifies execution of the Redis INFO command (case-insensitive), which retrieves server configuration, version, memory usage, and runtime statistics. This behavior reflects service interrogation and environment fingerprinting activity. While INFO can be used legitimately by administrators, it is also commonly observed during automated scanning and pre-exploitation reconnaissance of exposed Redis instances.
