34.78.183.19 has a very high threat confidence level of 98%, originating from Brussels, Belgium, on the Google LLC network (396982). It has been observed across 251 sessions targeting FTP, MONGODB, SMB, HTTP, HTTPS and 3 other protocols, First observed on January 22, 2026, most recently active February 25, 2026.
FTP session where a client probes for valid usernames, attempts authentication, negotiates transfer settings (ASCII and UTF-8), retrieves the current working directory, changes directories, enters passive mode, issues directory listings, and sends NOOP to maintain the session. This sequence reflects structured post-authentication exploration of the FTP file system to map directory structure and available content.
Composite behavior identifying authenticated SMB activity where a client accesses both IPC$ and data shares, performs root directory reads, and binds to SAMR and SRVSVC RPC interfaces. This sequence is consistent with structured remote enumeration of host configuration, shared resources, and account information, often conducted prior to lateral movement or privilege escalation attempts.
FTP session where the client enters passive mode (PASV) and issues a LIST command to retrieve a directory listing from the server.
FTP session where the client authenticates, queries the working directory, sets transfer mode, and enters passive mode without performing any file transfer or directory listing.
Identifies HTTPS requests targeting the web server root path ("/"), typically used for initial service discovery, host validation, or baseline content inspection prior to deeper enumeration
Identifies HTTP requests targeting the web server root path ("/"), typically used for initial service discovery, host validation, or baseline content inspection prior to deeper enumeration.
