Tool: sqllauncher.dll

Names	sqllauncher.dll
Category	Malware
Type	Backdoor
Description	(Avast) Both DLLs, sqllauncher.dll and logon.dll, are primarily used as backdoors. These are installed as services by the aforementioned batch file. They both create a log file under the path: %COMMON_DOCUMENT%\WZ9JuN00.tmp aggregating errors during the backdoor’s runtime. Each entry contains an error code, an error message, and a timestamp formatted as “[yyyy-mm-dd hh-mm-ss] %error code% %message%”. If the infected device can’t connect to the C&C server, the malware attempts to determine whether the traffic is routed through a proxy. This information may be retrieved either from %WINDOWS%\debug\netlogon.cfg or from the TCP table. After successfully connecting to the C&C server, a secure communication channel (Schannel) is established and telemetry (OS version, username) is sent to the C&C server.
