8.216.5.140 has a threat confidence score of 50%. This IP address from Japan (AS45102, Alibaba US Technology Co., Ltd.) has been observed in 4 honeypot sessions targeting SMB, FTP protocols. Detected attack patterns include smb authenticated rpc service and account enumeration. First observed on March 10, 2026, most recently active April 26, 2026.
Identifies an SMB session where the IPC$ share is accessed and RPC bindings are established to the SAMR and SRVSVC interfaces via named pipes. The combination of IPC$ access, SAMR RPC binding (Security Account Manager Remote), and SRVSVC pipe interaction indicates authenticated enumeration of user accounts, groups, shares, or service information on a Windows host. This behavior reflects structured post-authentication reconnaissance against Windows systems rather than unauthenticated share scanning.
