The Caphaw client is a DLL which can easily be identified by its entry point code where it checks the fdwReason parameter. Detailed information on the available configuration in different versions is listed in Appendix 2. hijackcfg/upload_file, /hijackcfg /grabemails/, /hijackcfg/upload_file) have been added in newer clients. hijackcfg/backconnect, /hijackcfg/oskill) have become obsolete in later versions, while new features (e.g. Other than modifications to Caphaw which allow it to run more stably on an infected host, some small changes can be seen in its configuration parsing through different versions. One obvious change in this version was the improvement to the custom encryption method of strings to eliminate wasted spaces (four zero bytes) at each encrypted string. Even later, in version 1.8.x, there were only slight changes to the traffic data pattern and additional code obfuscation. No major structural changes were made at this point. In addition, the malware author created a test mode in order for the developer to be able to test the module and plug-in after download without being bothered by the newly added anti-VM and anti-debugging features.Ĭaphaw showed signs of stability when version 1.7.x was introduced in February 2013. The introduction of plug ins provided a more convenient way to introduce new functionalities and standardize communication with the master between different modules. Plug-ins were also introduced in this version to remove the limitations of the original ‘modules’ system. It also added anti-VM and anti-debug mechanisms so that the malicious payload would not trigger if it detected that it was running in a sandbox or debugging environment. In the 1.4.1 version, the memory injector was combined into the Caphaw client, hence the malware also needed to handle the situation when the Caphaw DLL client was not invoked by a memory injector. Most of the strings were not encrypted, hence they were visible after unpacking. Some other capabilities, such as VNC and archiver, could be downloaded from the Internet later, after the configuration files enabled them. Some of the modules, namely backsocket and dllhook, were bundled together with the Caphaw client in the custom packer. The 1.0.x versions of Caphaw client consisted only of master mode and slave mode.
