Message | ATTACK-RESPONSES file copied ok |
Summary | This event is generated by the successful completion of a file transfer operation. This may be indicative of post-compromise behavior indicating the use of a Windows command shell for copying files.
|
Impact | Serious. An attacker may have the ability to transfer files from the victim host.
|
Detailed Information | This event indicates that a file was successfully copied using Windows command line shell. The string "1 file(s) copied" is shown after the successful completion of a Windows "copy" command.
Seeing this response in HTTP traffic indicates that an attacker may have been able to spawn a shell bound to a web port and has successfully executed the copy command. Note that the source address of this event is actually the victim and not that of the attacker.
|
Affected Systems | |
Attack Scenarios | An attacker gains an access to a Windows web server via an IIS vulnerability and then copies "cmd.exe" into the directory accessible by the web server, thus creating a backdoor to access the system.
|
Ease of Attack | Simple. This may be post-attack behavior and can be indicative of the successful exploitation of a vulnerable system.
|
Corrective Action | Investigate the web server for other signs of compromise
Look for other events generated by the same IP addresses.
