Loading threat actor…
FIN13, also known as Elephant Beetle, is a financially motivated cybercriminal threat actor associated with intrusions into enterprise Windows and Linux environments. The group has used web-facing server compromise tradecraft, including exploitation of legacy IIS infrastructure and DLL side-loading, to execute malicious code. FIN13 has established persistence through Windows Registry Run keys, concealed artifacts through hidden files and directories and Windows file attributes, and decoded encoded malware with native utilities. Post-compromise activity includes obtaining administrative credentials from local files, enumerating files and directories, collecting host and network configuration information, and querying Active Directory Service Principal Names and associated accounts. FIN13 has used HTTP-based web-shell communications and command-and-control activity before exfiltrating stolen data.

SAP NetWeaver Invoker Servlet Exploit (CVE-2010-5326) The Invoker Servlet on SAP NetWeaver Application Server Java platforms, possibly before 7.3, does not require authentication, which allows remote attackers to execute arbitrary code via an HTTP or HTTPS request, as exploited in the wild in 2013 through 2016, aka a Detour attack.
This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
FIN13 has used IISCrack.dll as a side-loading technique to load a malicious version of httpodbc.dll on old IIS Servers (CVE-2001-0507).
FIN13 has exploited known vulnerabilities such as ... CVE-2015-7450 (WebSphere Application Server SOAP Deserialization Exploit) ... to gain initial access.
FIN13 has exploited known vulnerabilities such as CVE-2017-1000486 (Primefaces Application Expression Language Injection) ... to gain initial access.
