We see that port 5901 is running the VNC server as we configured. Beware, this will install a lot of stuff! Similar to the way that we converted the meterpreter session into a VNC session, we can use a post-exploitation module to get a VNC session out of any reverse connection that you might be able to achieve on the target machine. To test this hypothesis, we get back to the Kali Linux Machine, here we again performed the port scan using Nmap and we could see that indeed the service is detected on the new port and it is possible to connect to VNC at 4455. But if we go back to the terminal where we ran the module, we can see that we can capture the Challenge and Response for the VNC service that we faked. jemallocFreeBSDlibcFreeBSDphkmallocjemallocJason Evans 2005"je"2007Firefox3.0jemallocWindowsjemalloc2009Jason EvansjemallocFacebook2017Facebook jemallocarenas arenasmallocfreearenasjemalloc, CPURAMjemallocA Scalable Concurrent malloc(3) Implementation for FreeBSD, jemallocgithubhttps://github.com/jemalloc/jemalloc /root/Download/jemalloc, .so ex_stats_print.c, ./ex_stats_print.out.so.2./ex_stats_print.out: error while loading shared libraries: libjemalloc.so.2: cannot open shared object file: No such file or directorybenchmarkInstruction Cache Misses , jemalloc wikihttps://github.com/jemalloc/jemalloc/wiki/Use-Case, jemallocex_stats_print.cMALLOC_CONF=stats_print:true ./ex_stats_print.outjemalloc, numaSPEC CPUbenchmarkjemallocNUMA nodes, qq_29505453: This is a piece of unintended information that should not be visible in such a way.
